ARM: arm-soc: SoC updates for 3.8
This contains the bulk of new SoC development for this merge window. Two new platforms have been added, the sunxi platforms (Allwinner A1x SoCs) by Maxime Ripard, and a generic Broadcom platform for a new series of ARMv7 platforms from them, where the hope is that we can keep the platform code generic enough to have them all share one mach directory. The new Broadcom platform is contributed by Christian Daudt. Highbank has grown support for Calxeda's next generation of hardware, ECX-2000. clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also taken on maintainership of the platform. Beyond this there has been a bunch of work from a number of people on converting more platforms to IRQ domains, pinctrl conversion, cleanup and general feature enablement across most of the active platforms. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQyLCjAAoJEIwa5zzehBx3AdQP/R+L3+EQMjiEWt/p7g/ql5Em 0SnP92CcGzrjgLTg9z1FeOazfOsGnkZAYUlDRkqfKobH3VqkhYFFtt1/0x0KMahm xcowHgMBOyimFdWT9vLK3J8U6DLui5XrEG9LGH2VL+lqmfjIyP/OOF3mVc0/+pV9 WTLAsYswdBRSeiNuF43kqlfrOwF6xsPLgiNMlc82w6BzHqoHu6dOif5M9MqWaApS V74DPmwLD371Tyit6aHqt3JOqpgiPSHlmxkzomK+5idcW3Pa7HnzzFYmx85dk/eN J2siqIkoOu7tEfjIbNZTL2MYoX4tUUKv4qZZ3IOl3YSWaV3P5ilMApF01XVrkk8E DWOMhzte9hC7L90W+/kCPLF1VyeAhCem2KQWUitO71fKur3r+3ZaUokNVvWzkJIL 7aduxAJOV2hfLgEqbjbjF3o4S8p63OV3kzivFJM1And15zDJo4+qqOh67+bPo4jj +R4du+SqzXriw4i3tDLGVpdjDffk4D41tbLzgkWAtvGyoP45yeYfHAzAh0pDFPRv ASfZVmZ5PhwAUAkIMnpC2sjgmxMYff3SYqmDgnsqXES7rbDH/hG+teymtHFTyUQp m+f60DNotSMcMvkLdvruLSB4aeTiwbfOqPn/g+aXYUlPuNMq1fVWgN7EJKWkamK4 nRwaJmLwx1/ojcVbpy2G =YMKB -----END PGP SIGNATURE----- Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC updates from Olof Johansson: "This contains the bulk of new SoC development for this merge window.

Merge branch 'for-3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup changes from Tejun Heo:
"A lot of activities on cgroup side. The big changes are focused on
making cgroup hierarchy handling saner.
- cgroup_rmdir() had peculiar semantics - it allowed cgroup
destruction to be vetoed by individual controllers and tried to
drain refcnt synchronously. The vetoing never worked properly and
caused good deal of contortions in cgroup. memcg was the last
reamining user. Michal Hocko removed the usage and cgroup_rmdir()
path has been simplified significantly. This was done in a
separate branch so that the memcg people can base further memcg
changes on top.
- The above allowed cleaning up cgroup lifecycle management and
implementation of generic cgroup iterators which are used to
improve hierarchy support.
- cgroup_freezer updated to allow migration in and out of a frozen
cgroup and handle hierarchy. If a cgroup is frozen, all descendant
cgroups are frozen.
- netcls_cgroup and netprio_cgroup updated to handle hierarchy
properly.
- Various fixes and cleanups.
- Two merge commits. One to pull in memcg and rmdir cleanups (needed
to build iterators). The other pulled in cgroup/for-3.7-fixes for
device_cgroup fixes so that further device_cgroup patches can be
stacked on top."
Fixed up a trivial conflict in mm/memcontrol.c as per Tejun (due to

regmap: Updates for v3.8
Quite a few enhancements this time around, helpers and diagnostics for
the most part which is good to see:
- Addition of table based lookups for the register access checks from
Davide Ciminaghi, making life easier for drivers with big blocks of
similar registers.
- Allow drivers to get the irqdomain for regmap irq_chips, allowing the
domain to be used with other APIs.
- Debug improvements for paged register maps.
- Performance improvments for some of the diagnostic infrastructure,
very helpful for devices with large register maps.

Pull ARM OMAP serial updates from Russell King: "This series is a major reworking of the OMAP serial driver code fixing various bugs in the hardware-assisted flow control, extending up into serial_core for a couple of issues. These fixes have been done as a set of progressive changes and transformations in the hope that no new bugs will be introduced by this series. The problems are many-fold, from the driver not being informed about updated settings, to the driver not knowing what the intentions of the upper layers are. The first four patches tackle the serial_core layer, allowing it to provide the necessary information to drivers, and the remaining patches allow the OMAP serial driver to take advantage of this. This brings hardware assisted RTS/CTS and XON/OFF flow control into a useful state. These patches have been in linux-next for most of the last cycle; indeed they predate the previous merge window.

Pull scheduler updates from Ingo Molnar: "The biggest change affects group scheduling: we now track the runnable average on a per-task entity basis, allowing a smoother, exponential decay average based load/weight estimation instead of the previous binary on-the-runqueue/off-the-runqueue load weight method. This will inevitably disturb workloads that were in some sort of borderline balancing state or unstable equilibrium, so an eye has to be kept on regressions. For that reason the new load average is only limited to group scheduling (shares distribution) at the moment (which was also hurting the most from the prior, crude weight calculation and whose scheduling quality wins most from this change) - but we plan to extend this to regular SMP balancing as well in the future, which will simplify and speed up things a bit. Other changes involve ongoing preparatory work to extend NOHZ to the scheduler as well, eventually allowing completely irq-free user-space execution." * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) Revert "sched/autogroup: Fix crash on reboot when autogroup is disabled" cputime: Comment cputime's adjusting code cputime: Consolidate cputime adjustment code cputime: Rename thread_group_times to thread_group_cputime_adjusted cputime: Move thread_group_cputime() to sched code vtime: Warn if irqs aren't disabled on system time accounting APIs vtime: No need to disable irqs on vtime_account() vtime: Consolidate a bit the ctx switch code vtime: Explicitly account pending user time on process tick vtime: Remove the underscore prefix invasion sched/autogroup: Fix crash on reboot when autogroup is disabled cputime: Separate irqtime accounting from generic vtime cputime: Specialize irq vtime hooks kvm: Directly account vtime to system on guest switch vtime: Make vtime_account_system() irqsafe vtime: Gather vtime declarations to their own header file sched: Describe CFS load-balancer sched: Introduce temporary FAIR_GROUP_SCHED dependency for load-tracking sched: Make __update_entity_runnable_avg() fast sched: Update_cfs_shares at period edge ... |

now used in the default 'diff' output, making the sum of the
'baseline' column be 100%, eliminating blind spots.
* libtraceevent fixes for compiler warnings trying to make perf it
build on some distros, like fedora 14, 32-bit, some of the warnings
really pointed to real bugs.

Pull RCU update from Ingo Molnar:
"The major features of this tree are:
1. A first version of no-callbacks CPUs. This version prohibits
offlining CPU 0, but only when enabled via CONFIG_RCU_NOCB_CPU=y.
Relaxing this constraint is in progress, but not yet ready
for prime time. These commits were posted to LKML at
https://lkml.org/lkml/2012/10/30/724.
2. Changes to SRCU that allows statically initialized srcu_struct
structures. These commits were posted to LKML at
https://lkml.org/lkml/2012/10/30/296.
3. Restructuring of RCU's debugfs output. These commits were posted
to LKML at https://lkml.org/lkml/2012/10/30/341.
4. Additional CPU-hotplug/RCU improvements, posted to LKML at
https://lkml.org/lkml/2012/10/30/327.
Note that the commit eliminating __stop_machine() was judged to
be too-high of risk, so is deferred to 3.9.
5. Changes to RCU's idle interface, most notably a new module
parameter that redirects normal grace-period operations to
their expedited equivalents. These were posted to LKML at
https://lkml.org/lkml/2012/10/30/739.
6. Additional diagnostics for RCU's CPU stall warning facility,
posted to LKML at https://lkml.org/lkml/2012/10/30/315.
The most notable change reduces the
default RCU CPU stall-warning time from 60 seconds to 21 seconds,
so that it once again happens sooner than the softlockup timeout.
7. Documentation updates, which were posted to LKML at
https://lkml.org/lkml/2012/10/30/280.
A couple of late-breaking changes were posted at
https://lkml.org/lkml/2012/11/16/634 and
https://lkml.org/lkml/2012/11/16/547.
8. Miscellaneous fixes, which were posted to LKML at
https://lkml.org/lkml/2012/10/30/309.
9. Finally, a fix for an lockdep-RCU splat was posted to LKML
at https://lkml.org/lkml/2012/11/7/486."

mm, memory-hotplug: dynamic configure movable memory and portion memory
Add online_movable and online_kernel for logic memory hotplug. This is the dynamic version of "movablecore" & "kernelcore". We have the same reason to introduce it as to introduce "movablecore" & "kernelcore". It has the same motive as "movablecore" & "kernelcore", but it is dynamic/running-time: o We can configure memory as kernelcore or movablecore after boot. Userspace workload is increased, we need more hugepage, we can't use "online_movable" to add memory and allow the system use more THP(transparent-huge-page), vice-verse when kernel workload is increase. Also help for virtualization to dynamic configure host/guest's memory, to save/(reduce waste) memory. Memory capacity on Demand o When a new node is physically online after boot, we need to use "online_movable" or "online_kernel" to configure/portion it as we expected when we logic-online it. This configuration also helps for physically-memory-migrate. o all benefit as the same as existed "movablecore" & "kernelcore". o Preparing for movable-node, which is very important for power-saving, hardware partitioning and high-available-system(hardware fault management). (Note, we don't introduce movable-node here.) Action behavior: When a memoryblock/memorysection is onlined by "online_movable", the kernel will not have directly reference to the page of the memoryblock, thus we can remove that memory any time when needed. When it is online by "online_kernel", the kernel can use it. When it is online by "online", the zone type doesn't changed. Current constraints: Only the memoryblock which is adjacent to the ZONE_MOVABLE can be online from ZONE_NORMAL to ZONE_MOVABLE.

mm, oom: fix race when specifying a thread as the oom origin
test_set_oom_score_adj() and compare_swap_oom_score_adj() are used to specify that current should be killed first if an oom condition occurs in between the two calls. The usage is short oom_score_adj = test_set_oom_score_adj(OOM_SCORE_ADJ_MAX); ... compare_swap_oom_score_adj(OOM_SCORE_ADJ_MAX, oom_score_adj); to store the thread's oom_score_adj, temporarily change it to the maximum score possible, and then restore the old value if it is still the same. This happens to still be racy, however, if the user writes OOM_SCORE_ADJ_MAX to /proc/pid/oom_score_adj in between the two calls. The compare_swap_oom_score_adj() will then incorrectly reset the old value prior to the write of OOM_SCORE_ADJ_MAX. To fix this, introduce a new oom_flags_t member in struct signal_struct that will be used for per-thread oom killer flags. KSM and swapoff can now use a bit in this member to specify that threads should be killed first in oom conditions without playing around with oom_score_adj. This also allows the correct oom_score_adj to always be shown when reading /proc/pid/oom_score.

Memory fragmentation introduced by ballooning might reduce significantly the number of 2MB contiguous memory blocks that can be used within a guest, thus imposing performance penalties associated with the reduced number of transparent huge pages that could be used by the guest workload. This patch-set follows the main idea discussed at 2012 LSFMMS session: "Ballooning for transparent huge pages" -- http://lwn.net/Articles/490114/ to introduce the required changes to the virtio_balloon driver, as well as the changes to the core compaction & migration bits, in order to make those subsystems aware of ballooned pages and allow memory balloon pages become movable within a guest, thus avoiding the aforementioned fragmentation issue Following are numbers that prove this patch benefits on allowing compaction to be more effective at memory ballooned guests.

mm: augment vma rbtree with rb_subtree_gap
Define vma->rb_subtree_gap as the largest gap between any vma in the subtree rooted at that vma, and their predecessor. Or, for a recursive definition, vma->rb_subtree_gap is the max of: - vma->vm_start - vma->vm_prev->vm_end - rb_subtree_gap fields of the vmas pointed by vma->rb.rb_left and vma->rb.rb_right This will allow get_unmapped_area_* to find a free area of the right size in O(log(N)) time, instead of potentially having to do a linear walk across all the VMAs. Also define mm->highest_vm_end as the vm_end field of the highest vma, so that we can easily check if the following gap is suitable. This does have the potential to make unmapping VMAs more expensive, especially for processes with very large numbers of VMAs, where the VMA rbtree can grow quite deep.

mm: support more pagesizes for MAP_HUGETLB/SHM_HUGETLB
There was some desire in large applications using MAP_HUGETLB or SHM_HUGETLB to use 1GB huge pages on some mappings, and stay with 2MB on others. This is useful together with NUMA policy: use 2MB interleaving on some mappings, but 1GB on local mappings. This patch extends the IPC/SHM syscall interfaces slightly to allow specifying the page size. It borrows some upper bits in the existing flag arguments and allows encoding the log of the desired page size in addition to the *_HUGETLB flag. When 0 is specified the default size is used, this makes the change fully compatible. Extending the internal hugetlb code to handle this is straight forward. Instead of a single mount it just keeps an array of them and selects the right mount based on the specified page size. When no page size is specified it uses the mount of the default page size. The change is not visible in /proc/mounts because internal mounts don't appear there. It also has very little overhead: the additional mounts just consume a super block, but not more memory when not used. I also exported the new flags to the user headers (they were previously under __KERNEL__). Right now only symbols for x86 and some other architecture for 1GB and 2MB are defined. The interface should already work for all other architectures though. Only architectures that define multiple hugetlb sizes actually need it (that is currently x86, tile, powerpc). However tile and powerpc have user configurable hugetlb sizes, so it's not easy to add defines. A program on those architectures would need to query sysfs and use the appropiate log2.

mm: thp: set the accessed flag for old pages on access fault
On x86 memory accesses to pages without the ACCESSED flag set result in the ACCESSED flag being set automatically. With the ARM architecture a page access fault is raised instead (and it will continue to be raised until the ACCESSED flag is set for the appropriate PTE/PMD). For normal memory pages, handle_pte_fault will call pte_mkyoung (effectively setting the ACCESSED flag). For transparent huge pages, pmd_mkyoung will only be called for a write fault. This patch ensures that faults on transparent hugepages which do not result in a CoW update the access flags for the faulting pmd.

memory_hotplug: fix possible incorrect node_states[N_NORMAL_MEMORY]
Currently memory_hotplug only manages the node_states[N_HIGH_MEMORY], it forgets to manage node_states[N_NORMAL_MEMORY]. This may cause node_states[N_NORMAL_MEMORY] to become incorrect. Example, if a node is empty before online, and we online a memory which is in ZONE_NORMAL. And after online, node_states[N_HIGH_MEMORY] is correct, but node_states[N_NORMAL_MEMORY] is incorrect, the online code doesn't set the new online node to node_states[N_NORMAL_MEMORY]. The same thing will happen when offlining (the offline code doesn't clear the node from node_states[N_NORMAL_MEMORY] when needed). Some memory managment code depends node_states[N_NORMAL_MEMORY], so we have to fix up the node_states[N_NORMAL_MEMORY]. We add node_states_check_changes_online() and node_states_check_changes_offline() to detect whether node_states[N_HIGH_MEMORY] and node_states[N_NORMAL_MEMORY] are changed while hotpluging. Also add @status_change_nid_normal to struct memory_notify, thus the memory hotplug callbacks know whether the node_states[N_NORMAL_MEMORY] are changed. (We can add a @flags and reuse @status_change_nid instead of introducing @status_change_nid_normal, but it will add much more complexity in memory hotplug callback in every subsystem. So introducing @status_change_nid_normal is better and it doesn't change the sematics of @status_change_nid) Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> Cc: David Rientjes <rientjes@google.com> Cc: Minchan Kim <minchan.kim@gmail.com> Cc: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Cc: Yasuaki Ishimatsu <isimatu.yasuaki@jp.fujitsu.com> Cc: Rob Landley <rob@landley.net> Cc: Jiang Liu <jiang.liu@huawei.com> Cc: Kay Sievers <kay.sievers@vrfy.org> Cc: Greg Kroah-Hartman <gregkh@suse.de> Cc: Mel Gorman <mgorman@suse.de> Cc: Wen Congyang <wency@cn.fujitsu.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Driver core updates for 3.8-rc1
Here's the large driver core updates for 3.8-rc1.
The biggest thing here is the various __dev* marking removals. This is
going to be a pain for the merge with different subsystem trees, I know,
but all of the patches included here have been ACKed by their various
subsystem maintainers, as they wanted them to go through here.
If this is too much of a pain, I can pull all of them out of this tree
and just send you one with the other fixes/updates and then, after
3.8-rc1 is out, do the rest of the removals to ensure we catch them all,
it's up to you. The merges should all be trivial, and Stephen has been
doing them all in linux-next for a few weeks now quite easily.
Other than the __dev* marking removals, there's nothing major here, some
firmware loading updates and other minor things in the driver core.
All of these have (much to Stephen's annoyance), been in linux-next for
a while.

This is the pinctrl big pull request for v3.8.
As can be seen from the diffstat the major changes
are:
- A big conversion of the AT91 pinctrl driver and
the associated ACKed platform changes under
arch/arm/max-at91 and its device trees. This
has been coordinated with the AT91 maintainers
to go in through the pinctrl tree.
- A larger chunk of changes to the SPEAr drivers
and the addition of the "plgpio" driver for the
SPEAr as well.
- The removal of the remnants of the Nomadik driver
from the arch/arm tree and fusion of that into
the Nomadik driver and platform data header files.
- Some local movement in the Marvell MVEBU drivers,
these now have their own subdirectory.
- The addition of a chunk of code to gpiolib under
drivers/gpio to register gpio-to-pin range mappings
from the GPIO side of things. This has been
requested by Grant Likely and is now implemented,
it is particularly useful for device tree work.
Then we have incremental updates all over the place,
many of these are cleanups and fixes from Axel Lin
who has done a great job of removing minor mistakes
and compilation annoyances.
