KVM: PPC: Book3S HV: Add support for DABRX register on POWER7
The DABRX (DABR extension) register on POWER7 processors provides finer control over which accesses cause a data breakpoint interrupt. It contains 3 bits which indicate whether to enable accesses in user, kernel and hypervisor modes respectively to cause data breakpoint interrupts, plus one bit that enables both real mode and virtual mode accesses to cause interrupts. Currently, KVM sets DABRX to allow both kernel and user accesses to cause interrupts while in the guest. This adds support for the guest to specify other values for DABRX. PAPR defines a H_SET_XDABR hcall to allow the guest to set both DABR and DABRX with one call. This adds a real-mode implementation of H_SET_XDABR, which shares most of its code with the existing H_SET_DABR implementation. To support this, we add a per-vcpu field to store the DABRX value plus code to get and set it via the ONE_REG interface. For Linux guests to use this new hcall, userspace needs to add "hcall-xdabr" to the set of strings in the /chosen/hypertas-functions property in the device tree. If userspace does this and then migrates the guest to a host where the kernel doesn't include this patch, then userspace will need to implement H_SET_XDABR by writing the specified DABR value to the DABR using the ONE_REG interface. In that case, the old kernel will set DABRX to DABRX_USER | DABRX_KERNEL. That should still work correctly, at least for Linux guests, since Linux guests cope with getting data breakpoint interrupts in modes that weren't requested by just ignoring the interrupt, and Linux guests never set DABRX_BTI. The other thing this does is to make H_SET_DABR and H_SET_XDABR work on POWER8, which has the DAWR and DAWRX instead of DABR/X. Guests that know about POWER8 should use H_SET_MODE rather than H_SET_[X]DABR, but guests running in POWER7 compatibility mode will still use H_SET_[X]DABR. For them, this adds the logic to convert DABR/X values into DAWR/X values on POWER8. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Alexander Graf <agraf@suse.de> |

Here are the 3.13 KVM changes. There was a lot of work on the PPC
side: the HV and emulation flavors can now coexist in a single kernel is probably the most interesting change from a user point of view. On the x86 side there are nested virtualization improvements and a few bugfixes. ARM got transparent huge page support, improved overcommit, and support for big endian guests. Finally, there is a new interface to connect KVM with VFIO. This helps with devices that use NoSnoop PCI transactions, letting the driver in the guest execute WBINVD instructions. This includes some nVidia cards on Windows, that fail to start without these patches and the corresponding userspace changes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABAgAGBQJShPAhAAoJEBvWZb6bTYbyl48P/297GgmELHAGBgjvb6q7yyGu L8+eHjKbh4XBAkPwyzbvUjuww5z2hM0N3JQ0BDV9oeXlO+zwwCEns/sg2Q5/NJXq XxnTeShaKnp9lqVBnE6G9rAOUWKoyLJ2wItlvUL8JlaO9xJ0Vmk0ta4n2Nv5GqDp db6UD7vju6rHtIAhNpvvAO51kAOwc01xxRixCVb7KUYOnmO9nvpixzoI/S0Rp1gu w/OWMfCosDzBoT+cOe79Yx1OKcpaVW94X6CH1s+ShCw3wcbCL2f13Ka8/E3FIcuq vkZaLBxio7vjUAHRjPObw0XBW4InXEbhI1DjzIvm8dmc4VsgmtLQkTCG8fj+jINc dlHQUq6Do+1F4zy6WMBUj8tNeP1Z9DsABp98rQwR8+BwHoQpGQBpAxW0TE0ZMngC t1caqyvjZ5pPpFUxSrAV+8Kg4AvobXPYOim0vqV7Qea07KhFcBXLCfF7BWdwq/Jc 0CAOlsLL4mHGIQWZJuVGw0YGP7oATDCyewlBuDObx+szYCoV4fQGZVBEL0KwJx/1 7lrLN7JWzRyw6xTgJ5VVwgYE1tUY4IFQcHu7/5N+dw8/xg9KWA3f4PeMavIKSf+R qteewbtmQsxUnvuQIBHLs8NRWPnBPy+F3Sc2ckeOLIe4pmfTte6shtTXcLDL+LqH NTmT/cfmYp2BRkiCfCiS =rWNf -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM changes from Paolo Bonzini: "Here are the 3.13 KVM changes.

mm: dynamically allocate page->ptl if it cannot be embedded to struct page
If split page table lock is in use, we embed the lock into struct page of table's page. We have to disable split lock, if spinlock_t is too big be to be embedded, like when DEBUG_SPINLOCK or DEBUG_LOCK_ALLOC enabled. This patch add support for dynamic allocation of split page table lock if we can't embed it to struct page. page->ptl is unsigned long now and we use it as spinlock_t if sizeof(spinlock_t) <= sizeof(long), otherwise it's pointer to spinlock_t. The spinlock_t allocated in pgtable_page_ctor() for PTE table and in pgtable_pmd_page_ctor() for PMD table. All other helpers converted to support dynamically allocated page->ptl.

fbdev changes for 3.13
Nothing particularly stands out in this pull request. The biggest part of the changes are cleanups. Maybe one fix to mention is the "fb: reorder the lock sequence to fix potential dead lock" which hopefully fixes the fb locking issues reported by multiple persons. There are also a few commits that have changes to arch/arm/mach-at91 and arch/avr32, which have been acked by the maintainers. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.14 (GNU/Linux) iQIcBAABAgAGBQJSg2oCAAoJEPo9qoy8lh71vXsP/2AjkzOlcKBPutMG/W30QMHT tkKfr/RL8C3oXcimkE6ch3ksbFj2t5corxa/DLTdESdTpeFAgxj72pcdhN3X4+Xs 7IokExM2W5s6p4pP66PTr2A5XhEyAHtEMp+2JbHPRzwZitblzBLZvuPUJljwJDpj Z9+sD00xv/MZrXDCsEN8k2xdJ3rFn6JgX267y1qajlsocZoseTF2ed94IN/YnIM7 B2hra1B4E21FPYLzRDOJRmZa0YGomLTymezPnPg33hLBhnJU/aG4HLDHKUZWhduz /6UwACH63ja7I2z/8AZHQ1ACdbGheRtHbjwV9LLYlbaAvPmUqNTZ4b6UeQOb/EZ0 3SPCYbwD6+RMhSx/j/XhySvw82RY0i1aTlTDyjgOggfrfdi4x1Wk54bUWp5l9O3D SX1vSpNLGSh4GKXRzJjf3jouG/LcOzlpDlVZXzgsPzkyirluUv6QdMTopJwFwIGx rFgtsbkvhEsFvaNhhVIqQXKfwZ69r42U5JC+fDM5u7VX0mqyJ1usUNGvNSeifcDg EwUAI6RGnOXCO6crj2BZYpRTdc61tnY9b4CGLHDCeQkEXokEsEJ7Mz+8YfSwFo7X wqh+dAPQaixeHtUFZ8GhHXeAsjoQRSBXygf3NSNmCeP3WsmuozbauuujSrrTHITp LOXFPhU9uxHu4mDd6wrq =59+j -----END PGP SIGNATURE----- Merge tag 'fbdev-3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux Pull fbdev changes from Tomi Valkeinen: "Nothing particularly stands out in this pull request.

Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm
Pull DMA mask updates from Russell King: "This series cleans up the handling of DMA masks in a lot of drivers, fixing some bugs as we go. Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ... |

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking updates from David Miller: 1) The addition of nftables. No longer will we need protocol aware firewall filtering modules, it can all live in userspace. At the core of nftables is a, for lack of a better term, virtual machine that executes byte codes to inspect packet or metadata (arriving interface index, etc.) and make verdict decisions. Besides support for loading packet contents and comparing them, the interpreter supports lookups in various datastructures as fundamental operations. For example sets are supports, and therefore one could create a set of whitelist IP address entries which have ACCEPT verdicts attached to them, and use the appropriate byte codes to do such lookups. Since the interpreted code is composed in userspace, userspace can do things like optimize things before giving it to the kernel. Another major improvement is the capability of atomically updating portions of the ruleset. In the existing netfilter implementation, one has to update the entire rule set in order to make a change and this is very expensive. Userspace tools exist to create nftables rules using existing netfilter rule sets, but both kernel implementations will need to co-exist for quite some time as we transition from the old to the new stuff. Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have worked so hard on this. 2) Daniel Borkmann and Hannes Frederic Sowa made several improvements to our pseudo-random number generator, mostly used for things like UDP port randomization and netfitler, amongst other things. In particular the taus88 generater is updated to taus113, and test cases are added. 3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet and Yang Yingliang. 4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin Sujir. 5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet, Neal Cardwell, and Yuchung Cheng. 6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary control message data, much like other socket option attributes. From Francesco Fusco. 7) Allow applications to specify a cap on the rate computed automatically by the kernel for pacing flows, via a new SO_MAX_PACING_RATE socket option. From Eric Dumazet. 8) Make the initial autotuned send buffer sizing in TCP more closely reflect actual needs, from Eric Dumazet. 9) Currently early socket demux only happens for TCP sockets, but we can do it for connected UDP sockets too. Implementation from Shawn Bohrer. 10) Refactor inet socket demux with the goal of improving hash demux performance for listening sockets. With the main goals being able to use RCU lookups on even request sockets, and eliminating the listening lock contention. From Eric Dumazet. 11) The bonding layer has many demuxes in it's fast path, and an RCU conversion was started back in 3.11, several changes here extend the RCU usage to even more locations. From Ding Tianhong and Wang Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav Falico. 12) Allow stackability of segmentation offloads to, in particular, allow segmentation offloading over tunnels. From Eric Dumazet. 13) Significantly improve the handling of secret keys we input into the various hash functions in the inet hashtables, TCP fast open, as well as syncookies. From Hannes Frederic Sowa. The key fundamental operation is "net_get_random_once()" which uses static keys. Hannes even extended this to ipv4/ipv6 fragmentation handling and our generic flow dissector. 14) The generic driver layer takes care now to set the driver data to NULL on device removal, so it's no longer necessary for drivers to explicitly set it to NULL any more. Many drivers have been cleaned up in this way, from Jingoo Han. 15) Add a BPF based packet scheduler classifier, from Daniel Borkmann. 16) Improve CRC32 interfaces and generic SKB checksum iterators so that SCTP's checksumming can more cleanly be handled. Also from Daniel Borkmann. 17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces using the interface MTU value. This helps avoid PMTU attacks, particularly on DNS servers. From Hannes Frederic Sowa. 18) Use generic XPS for transmit queue steering rather than internal (re-)implementation in virtio-net. From Jason Wang. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1622 commits) random32: add test cases for taus113 implementation random32: upgrade taus88 generator to taus113 from errata paper random32: move rnd_state to linux/random.h random32: add prandom_reseed_late() and call when nonblocking pool becomes initialized random32: add periodic reseeding random32: fix off-by-one in seeding requirement PHY: Add RTL8201CP phy_driver to realtek xtsonic: add missing platform_set_drvdata() in xtsonic_probe() macmace: add missing platform_set_drvdata() in mace_probe() ethernet/arc/arc_emac: add missing platform_set_drvdata() in arc_emac_probe() ipv6: protect for_each_sk_fl_rcu in mem_check with rcu_read_lock_bh vlan: Implement vlan_dev_get_egress_qos_mask as an inline. ixgbe: add warning when max_vfs is out of range. igb: Update link modes display in ethtool netfilter: push reasm skb through instead of original frag skbs ip6_output: fragment outgoing reassembled skb properly MAINTAINERS: mv643xx_eth: take over maintainership from Lennart net_sched: tbf: support of 64bit rates ixgbe: deleting dfwd stations out of order can cause null ptr deref ixgbe: fix build err, num_rx_queues is only available with CONFIG_RPS ... |

Discussion at Kernel Summit made it clear that the presence or absence of specific Kconfig symbols are not considered ABI, and that no userspace (or bootloader, etc) should rely on them.

vsprintf: check real user/group id for %pK
Some setuid binaries will allow reading of files which have read permission by the real user id. This is problematic with files which use %pK because the file access permission is checked at open() time, but the kptr_restrict setting is checked at read() time. If a setuid binary opens a %pK file as an unprivileged user, and then elevates permissions before reading the file, then kernel pointer values may be leaked. This happens for example with the setuid pppd application on Ubuntu 12.04: $ head -1 /proc/kallsyms 00000000 T startup_32 $ pppd file /proc/kallsyms pppd: In file /proc/kallsyms: unrecognized option 'c1000000' This will only leak the pointer value from the first line, but other setuid binaries may leak more information. Fix this by adding a check that in addition to the current process having CAP_SYSLOG, that effective user and group ids are equal to the real ids. If a setuid binary reads the contents of a file which uses %pK then the pointer values will be printed as NULL if the real user is unprivileged. Update the sysctl documentation to reflect the changes, and also correct the documentation to state the kptr_restrict=0 is the default. This is a only temporary solution to the issue. The correct solution is to do the permission check at open() time on files, and to replace %pK with a function which checks the open() time permission. %pK uses in printk should be removed since no sane permission check can be done, and instead protected by using dmesg_restrict.

drivers/char/hpet.c: allow user controlled mmap for user processes
The CONFIG_HPET_MMAP Kconfig option exposes the memory map of the HPET registers to userspace. The Kconfig help points out that in some cases this can be a security risk as some systems may erroneously configure the map such that additional data is exposed to userspace. This is a problem for distributions -- some users want the MMAP functionality but it comes with a significant security risk. In an effort to mitigate this risk, and due to the low number of users of the MMAP functionality, I've introduced a kernel parameter, hpet_mmap_enable, that is required in order to actually have the HPET MMAP exposed.

mm: improve the description for dirty_background_ratio/dirty_ratio sysctl
Now dirty_background_ratio/dirty_ratio contains a percentage of total avaiable memory, which contains free pages and reclaimable pages. The number of these pages is not equal to the number of total system memory. But they are described as a percentage of total system memory in Documentation/sysctl/vm.txt. So we need to fix them to avoid misunderstanding.

mem-hotplug: introduce movable_node boot option
The hot-Pluggable field in SRAT specifies which memory is hotpluggable. As we mentioned before, if hotpluggable memory is used by the kernel, it cannot be hot-removed. So memory hotplug users may want to set all hotpluggable memory in ZONE_MOVABLE so that the kernel won't use it. Memory hotplug users may also set a node as movable node, which has ZONE_MOVABLE only, so that the whole node can be hot-removed. But the kernel cannot use memory in ZONE_MOVABLE. By doing this, the kernel cannot use memory in movable nodes. This will cause NUMA performance down. And other users may be unhappy. So we need a way to allow users to enable and disable this functionality. In this patch, we introduce movable_node boot option to allow users to choose to not to consume hotpluggable memory at early boot time and later we can set it as ZONE_MOVABLE. To achieve this, the movable_node boot option will control the memblock allocation direction. That said, after memblock is ready, before SRAT is parsed, we should allocate memory near the kernel image as we explained in the previous patches. So if movable_node boot option is set, the kernel does the following: 1. After memblock is ready, make memblock allocate memory bottom up. 2. After SRAT is parsed, make memblock behave as default, allocate memory top down. Users can specify "movable_node" in kernel commandline to enable this functionality. For those who don't use memory hotplug or who don't want to lose their NUMA performance, just don't specify anything. The kernel will work as before.

memcg: support hierarchical memory.numa_stats
The memory.numa_stat file was not hierarchical. Memory charged to the children was not shown in parent's numa_stat. This change adds the "hierarchical_" stats to the existing stats. The new hierarchical stats include the sum of all children's values in addition to the value of the memcg. Tested: Create cgroup a, a/b and run workload under b. The values of b are included in the "hierarchical_*" under a. $ cd /sys/fs/cgroup $ echo 1 > memory.use_hierarchy $ mkdir a a/b Run workload in a/b: $ (echo $BASHPID >> a/b/cgroup.procs && cat /some/file && bash) & The hierarchical_ fields in parent (a) show use of workload in a/b: $ cat a/memory.numa_stat total=0 N0=0 N1=0 N2=0 N3=0 file=0 N0=0 N1=0 N2=0 N3=0 anon=0 N0=0 N1=0 N2=0 N3=0 unevictable=0 N0=0 N1=0 N2=0 N3=0 hierarchical_total=908 N0=552 N1=317 N2=39 N3=0 hierarchical_file=850 N0=549 N1=301 N2=0 N3=0 hierarchical_anon=58 N0=3 N1=16 N2=39 N3=0 hierarchical_unevictable=0 N0=0 N1=0 N2=0 N3=0 $ cat a/b/memory.numa_stat total=908 N0=552 N1=317 N2=39 N3=0 file=850 N0=549 N1=301 N2=0 N3=0 anon=58 N0=3 N1=16 N2=39 N3=0 unevictable=0 N0=0 N1=0 N2=0 N3=0 hierarchical_total=908 N0=552 N1=317 N2=39 N3=0 hierarchical_file=850 N0=549 N1=301 N2=0 N3=0 hierarchical_anon=58 N0=3 N1=16 N2=39 N3=0 hierarchical_unevictable=0 N0=0 N1=0 N2=0 N3=0 Signed-off-by: Ying Han <yinghan@google.com> Signed-off-by: Greg Thelen <gthelen@google.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Michal Hocko <mhocko@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

GPIO bulk changes for the v3.13 development cycle
- Merged the GPIO descriptor API from Alexandre Courbot. This is a first step toward trying to get rid of the global GPIO numberspace for the future. - Add an API so that driver can flag that a certain GPIO line is being used by a irqchip backend for generating IRQs, so that we can enforce checks, like not allowing users to switch that line to an output at runtime, since this makes no sense. Implemented corresponding calls in a few select drivers. - ACPI GPIO cleanups, refactorings and switch to using the descriptor-based interface. - Support for the TPS80036 Palmas GPIO variant. - A new driver for the Broadcom Kona GPIO SoC IP block. - Device tree support for the PCF857x driver. - A set of ARM GPIO refactorings with the goal of getting rid of a bunch of custom GPIO implementations from the arch/arm/* tree: - Move the IOP GPIO driver to the GPIO subsystem and fix all users to use the gpiolib API for accessing GPIOs. Delete the old custom GPIO implementation. - Delete the unused custom PXA GPIO implemention. - Convert all users of the IXP4 custom GPIO implementation to use gpiolib and delete the custom implementation. - Delete the custom Gemini GPIO implementation, also completely unused. - Various cleanups and renamings. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) iQIcBAABAgAGBQJSgNF3AAoJEEEQszewGV1zPiwP/RdQTL8KTe2ULL2QpKAj2TSP wuqbvSfW0AOUVf7SvUwXYctxnA718orH2rFKRM9UjK2XFEYgNrtsL4e2Igtbo057 uZ1sr+dytxgLC67CqkbYTfFxQZZ97ZCO3j8VWtVRxcpMEpoE10Y09ZW7nzvF3Lhq 0lRd+Cf4KirurOAVfQOVA0Fv+zKuSKSD0i8FLq60li/5EaxXPrYlene4SNY/B+ue IWvLJfeDRkv8dR11LYdI/WIET7ljMfIb4MEA5FQ0hae0SSlQtZHQBQi8PjnWnHX0 n+kxFBFMhWPqBDVwbheD4u6U0RFrm8IVfgdVG94G7wlIQXd5TY4d9Nzd2Y5+bzDF THHZiM9PdzU2rjV2QN5gV+AHJuLw/7tSB9pBpcAtKbwb0FFholUDImWI45YoJAdx d949YAblh7QZ2nFJJtNgzerco0XAT6BA5/Bs9TPx3L4tij2e+YZzhJbW/EeNmICo rE98wUdpV9pk6siv56bsoLowCjNOwaWmI6aYErBdh21mTNx65kwd40xWb3ylM3sy X1QC/oLhqxc7Il/KvF9DbGvpgg5QUB1mY9eb2B+gOhRO0cg+qiWvvvqi0dcTHkaT aqg7BPXVGUMO73qSsV1x7hmOWsqSFxCBSkVFyWJO7GxqarmWvsXiVh72E85pK60P RSyJ/5TghCiGAPFWsg/7 =881E -----END PGP SIGNATURE----- Merge tag 'gpio-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO changes from Linus Walleij: "Here is the bulk of GPIO changes for the v3.13 development cycle.

Main pin control pull request for the v3.13 cycle:
- Blackfin ADI pin control driver, we move yet another architecture under this subsystem umbrella. - Incremental updates to the Renesas Super-H PFC pin control driver. New subdriver for the r8a7791 SoC. - Non-linear GPIO ranges from the gpiolib side of things, this enabled simplified device tree bindings by referring entire groups of pins on some pin controller to act as back-end for a certain GPIO-chip driver. - Add the Abilis TB10x pin control driver used on the ARC architecture. Also the corresponding GPIO driver is merged through this tree, so the ARC has full support for pins and GPIOs after this. - Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller instances. The i.MX1 and i.MX27 is an entirely new family (silicon) of controllers whereas i.MX50 is a variant of the previous supported controller. - Then the usual slew of fixes, cleanups and incremental updates. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) iQIcBAABAgAGBQJSgHrbAAoJEEEQszewGV1zX/gP/R4mAl5rixzu7RDC0nlUHz2S F7zf3nhtsAM9GnvJjh9lE43nrisDdCnnBMFeqb7fEr3sp3j+BjQZLp4w/gbkakfY 6xx6dQ+1+fGojd/gqZI9Le6afpBasAz2E8trariOXW5TmET9ai1y9JCmE2l9K3xA jX3h138iUZ4SihBW7c/Ib46TWfe7vaeAF0WKpfNie/uMHYyc+nXQXNNvtzxtk+N3 +MMuxr9io+d3OyORHD5PlbwWs+jhEPKXfy/isudlkeGbPrA+CMxTCmRc5iu8AvTv L0wE6FnBhrdbTUHp9fGmdo1sxmIsijYbbc16yVQOn5kAr/hZvmltjV8efBytEep/ 268ruds2l3TWypaPotuj8Z3Fxm0Jr/+tcQ9Ck8CTMdrGG3J5D78U8fLwVKTcfzJ5 QjaG0c39MYBbDPO29wfr93MJF7BoNm0D4AyypOCQiH17jL0Q7sXMpeW2WYqlgFf7 uIWnN3Vsh5V4DcYSCrXoHtts1Wn7i8QEkjyj5gQYvXBU47vGToX5xO6Llvr34lVV VGMhivC3f5Z1UmTImwhi+FkfdDVwBYEuiAo3J9ezGvls4Ywq4AjZV/QZB563CztE riZ/Xpw3djrxMLKMjGvebTRGpFHcVoh9XV3FetIk+2SCyK7DK1jyYRE1+tvKudAF TEIV8476kb7xIVbKt8Oy =z9SM -----END PGP SIGNATURE----- Merge tag 'pinctrl-for-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "Main pin control pull request for the v3.13 cycle.

dm cache: add cache block invalidation support
Cache block invalidation is removing an entry from the cache without writing it back. Cache blocks can be invalidated via the 'invalidate_cblocks' message, which takes an arbitrary number of cblock ranges: invalidate_cblocks [<cblock>|<cblock begin>-<cblock end>]* E.g. dmsetup message my_cache 0 invalidate_cblocks 2345 3456-4567 5678-6789 Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> |

dm cache: add passthrough mode
"Passthrough" is a dm-cache operating mode (like writethrough or writeback) which is intended to be used when the cache contents are not known to be coherent with the origin device. It behaves as follows: * All reads are served from the origin device (all reads miss the cache) * All writes are forwarded to the origin device; additionally, write hits cause cache block invalidates This mode decouples cache coherency checks from cache device creation, largely to avoid having to perform coherency checks while booting. Boot scripts can create cache devices in passthrough mode and put them into service (mount cached filesystems, for example) without having to worry about coherency. Coherency that exists is maintained, although the cache will gradually cool as writes take place. Later, applications can perform coherency checks, the nature of which will depend on the type of the underlying storage. If coherency can be verified, the cache device can be transitioned to writethrough or writeback mode while still warm; otherwise, the cache contents can be discarded prior to transitioning to the desired operating mode.
