net_sched: improve and refactor tcf_action_put_many()
tcf_action_put_many() is mostly called to clean up actions on
failure path, but tcf_action_put_many(&actions[acts_deleted]) is
used in the ugliest way: it passes a slice of the array and
uses an additional NULL at the end to avoid out-of-bound
access.
acts_deleted is completely unnecessary since we can teach
tcf_action_put_many() scan the whole array and checks against
NULL pointer. Which also means tcf_action_delete() should
set deleted action pointers to NULL to avoid double free.

hv_netvsc: ignore devices that are not PCI
Registering another device with same MAC address (such as TAP, VPN or
DPDK KNI) will confuse the VF autobinding logic. Restrict the search
to only run if the device is known to be a PCI attached VF.

net/ipv6: Put lwtstate when destroying fib6_info
Prior to the introduction of fib6_info lwtstate was managed by the dst
code. With fib6_info releasing lwtstate needs to be done when the struct
is freed.

qed: Avoid sending mailbox commands when MFW is not responsive
Keep sending mailbox commands to the MFW when it is not responsive ends up with a redundant amount of timeout expiries. This patch prints the MCP status on the first command which is not responded, and blocks the following commands. Since the (un)load request commands might be not responded due to other PFs, the patch also adds the option to skip the blocking upon a failure.

qed: Prevent a possible deadlock during driver load and unload
The MFW manages an internal lock to prevent concurrent hardware (de)initialization of different PFs. This, together with the busy-waiting for the MFW's responses for commands, might lead to a deadlock during concurrent load or unload of PFs. This patch adds the option to sleep within the busy-waiting, and uses it for the (un)load requests (which are not sent from an interrupt context) to prevent the possible deadlock.

qed: Wait for MCP halt and resume commands to take place
Successive iterations of halting and resuming the management chip (MCP) might fail, since currently the driver doesn't wait for these operations to actually take place.

qed: Wait for ready indication before rereading the shmem
The MFW might be reset and re-update its shared memory. Upon the detection of such a reset the driver rereads this memory, but it has to wait till the data is valid.

This because ip6n->tnls_wc[0] point to fallback device in default, but
in non-default namespace, ip6n->tnls_wc[0] will be NULL, so add the NULL

Minor code cleanups for PPC.
For x86 this brings in PCID emulation and CR3 caching for shadow page tables, nested VMX live migration, nested VMCS shadowing, an optimized IPI hypercall, and some optimizations. ARM will come next week. There is a semantic conflict because tip also added an .init_platform callback to kvm.c. Please keep the initializer from this branch, and add a call to kvmclock_init (added by tip) inside kvm_init_platform (added here). Also, there is a backmerge from 4.18-rc6. This is because of a refactoring that conflicted with a relatively late bugfix and resulted in a particularly hellish conflict. Because the conflict was only due to unfortunate timing of the bugfix, I backmerged and rebased the refactoring rather than force the resolution on you. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAABAgAGBQJbdwNFAAoJEL/70l94x66DiPEH/1cAGZWGd85Y3yRu1dmTmqiz kZy0V+WTQ5kyJF4ZsZKKOp+xK7Qxh5e9kLdTo70uPZCHwLu9IaGKN9+dL9Jar3DR yLPX5bMsL8UUed9g9mlhdaNOquWi7d7BseCOnIyRTolb+cqnM5h3sle0gqXloVrS UQb4QogDz8+86czqR8tNfazjQRKW/D2HEGD5NDNVY1qtpY+leCDAn9/u6hUT5c6z EtufgyDh35UN+UQH0e2605gt3nN3nw3FiQJFwFF1bKeQ7k5ByWkuGQI68XtFVhs+ 2WfqL3ftERkKzUOy/WoSJX/C9owvhMcpAuHDGOIlFwguNGroZivOMVnACG1AI3I= =9Mgw -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull first set of KVM updates from Paolo Bonzini: "PPC: - minor code cleanups x86: - PCID emulation and CR3 caching for shadow page tables - nested VMX live migration - nested VMCS shadowing - optimized IPI hypercall - some optimizations ARM will come next week" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (85 commits) kvm: x86: Set highest physical address bits in non-present/reserved SPTEs KVM/x86: Use CC_SET()/CC_OUT in arch/x86/kvm/vmx.c KVM: X86: Implement PV IPIs in linux guest KVM: X86: Add kvm hypervisor init time platform setup callback KVM: X86: Implement "send IPI" hypercall KVM/x86: Move X86_CR4_OSXSAVE check into kvm_valid_sregs() KVM: x86: Skip pae_root shadow allocation if tdp enabled KVM/MMU: Combine flushing remote tlb in mmu_set_spte() KVM: vmx: skip VMWRITE of HOST_{FS,GS}_BASE when possible KVM: vmx: skip VMWRITE of HOST_{FS,GS}_SEL when possible KVM: vmx: always initialize HOST_{FS,GS}_BASE to zero during setup KVM: vmx: move struct host_state usage to struct loaded_vmcs KVM: vmx: compute need to reload FS/GS/LDT on demand KVM: nVMX: remove a misleading comment regarding vmcs02 fields KVM: vmx: rename __vmx_load_host_state() and vmx_save_host_state() KVM: vmx: add dedicated utility to access guest's kernel_gs_base KVM: vmx: track host_state.loaded using a loaded_vmcs pointer KVM: vmx: refactor segmentation code in vmx_save_host_state() kvm: nVMX: Fix fault priority for VMX operations kvm: nVMX: Fix fault vector for VMX operation at CPL > 0 ... |

RISC-V Updates for the 4.19 Merge Window
This tag contains some major improvements to the RISC-V port, including the necessary interrupt controller and timer support to actually make it to userspace. Support for three devices has been added: * Support for the ISA-mandated timers on RISC-V systems. * Support for the ISA-mandated first-level interrupt controller on RISC-V systems, which is handled as part of our core arch code because it's very small and tightly tied to the ISA. * Support for SiFive's platform-level interrupt controller, which talks to the actual devices. In addition to these new devices, there are a handful of cleanups all over the RISC-V tree: * Build fixes for various configurations * A fix to the vDSO build's makefile so it respects CFLAGS. * The addition of __lshrti3, a libgcc derived function necessary for some 32-bit configurations. * !SMP && PERF_EVENTS * Cleanups to the arch code to remove the remnants of old versions of the drivers that were just properly submitted. * Some dead code from the timer driver, most of which wasn't ever even compiled. * Cleanups of some interrupt #defines, which are now local to the interrupt handling code. * Fixes to ptrace(), which while not being sufficient to fully make GDB work are at least sufficient to get simple GDB tasks to work. * Early printk support via RISC-V's architecturally mandated SBI console device. * A fix to our early debug trap handler to ensure it's always aligned. These patches have all been through a fairly extensive review process, but as this enables a whole pile of functionality (ie, userspace) I'm confident we'll need to submit a few more patches. The only concrete issues I know about are the sys_riscv_flush_icache patches, but as I managed to screw those up on Friday I figured it'd be best to let them bake another week. This tag boots a Fedora root filesystem on QEMU's master branch for me, and before this morning's rebase (from 4.18-rc8 to 4.18) it booted on the HiFive Unleashed. Thanks to Christoph Hellwig and the other guys at WD for getting the new drivers in shape! -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEAM520YNJYN/OiG3470yhUCzLq0EFAltx3HcTHHBhbG1lckBk YWJiZWx0LmNvbQAKCRDvTKFQLMurQc7nEACh8NCRLyXHOAQefomb+BUx+DJXweau lhTiPexB7+3ZAT6FvL8BgHFu3qMsgZ8iI5pxIz7tap2WRTlakRABLes7c3xQPI4a 3rDbZFE78lQDNY0Kj8iUpvYr0aOfMcC8aoD30qQHaWZVgYZvaZGD3Sar6VbTyaNe 5F5lRaiAtrMmHNio/fXQvnMP83nc1Nxzc4q8VeRjmufc0CvGZUs3L2ZRVx1phwav VedQFsrNHlcyulBv9rQXzaeyvVn+FNKlu4c/9sI6xsGZofGZjOqub1vjURuEfTc5 4AtdFMN0Xb2TYCK277Fr/FY/VEHGXCV+3hGc2U62hnpBtRgGERn7gQUimCJD5b+V gpXZGjtLvTXp9a4N6+ThC/oqvr72aLzInNap95MFK5xSMx/4AdCG7u63sd2qLtkL tlYho+Hd50ImIlUCTs6pfjzmgTMLW2huVJhDNx2lt9OUvNNYjTc4mjEK2WK8DUC7 aUMcHYZMn3hJFNwvd5xTxLPua4ahhhYTyfzHwnMiND4ZjdUnxtrKNj46HjSPqMp9 mgKOkv3G0a021gYODI/dweYI1SV2my814fQHZW4rcFYM2lLwrn2cPMMGezAJF9sR mbLHW6ZxJrtd9m+RZsJB9Z3QnBs68yIqTOBPRRFM5egwt9s9y+19HnBDVe1hj8/j OpmZ/qXCqQt+jA== =PfnC -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-4.19-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull RISC-V updates from Palmer Dabbelt: "This contains some major improvements to the RISC-V port, including the necessary interrupt controller and timer support to actually make it to userspace.

deprecate the '__deprecated' attribute warnings entirely and for good
We haven't had lots of deprecation warnings lately, but the rdma use of it made them flare up again. They are not useful. They annoy everybody, and nobody ever does anything about them, because it's always "somebody elses problem". And when people start thinking that warnings are normal, they stop looking at them, and the real warnings that mean something go unnoticed. If you want to get rid of a function, just get rid of it. Convert every user to the new world order. And if you can't do that, then don't annoy everybody else with your marking that says "I couldn't be bothered to fix this, so I'll just spam everybody elses build logs with warnings about my laziness". Make a kernelnewbies wiki page about things that could be cleaned up, write a blog post about it, or talk to people on the mailing lists. But don't add warnings to the kernel build about cleanup that you think should happen but you aren't doing yourself. Don't. Just don't. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1 There is a lot here, much more than normal, seems like everyone is writing new driver subsystems these days... Anyway, major things here are: - new FSI driver subsystem, yet-another-powerpc low-level hardware bus - gnss, finally an in-kernel GPS subsystem to try to tame all of the crazy out-of-tree drivers that have been floating around for years, combined with some really hacky userspace implementations. This is only for GNSS receivers, but you have to start somewhere, and this is great to see. Other than that, there are new slimbus drivers, new coresight drivers, new fpga drivers, and loads of DT bindings for all of these and existing drivers. Full details of everything is in the shortlog.

Staging/IIO patches for 4.19-rc1
Here are the big staging/iio patches for 4.19-rc1. Lots of churn here, with tons of cleanups happening in staging drivers, a removal of an old crypto driver that no one was using (skein), and the addition of some new IIO drivers. Also added was a "gasket" driver from Google that needs loads of work and the erofs filesystem. Even with adding all of the new drivers and a new filesystem, we are only adding about 1000 lines overall to the kernel linecount, which shows just how much cleanup happened, and how big the unused crypto driver was. All of these have been in the linux-next tree for a while now with no reported issues. Note, you will have a merge problem with a device tree IIO file and the MAINTAINERS file, both resolutions are easy, just take all changed. There will be a skein file merge issue as well, but that file got deleted so just drop that.

mm, vmacache: hash addresses based on pmd
When perf profiling a wide variety of different workloads, it was found that vmacache_find() had higher than expected cost: up to 0.08% of cpu utilization in some cases. This was found to rival other core VM functions such as alloc_pages_vma() with thp enabled and default mempolicy, and the conditionals in __get_vma_policy(). VMACACHE_HASH() determines which of the four per-task_struct slots a vma is cached for a particular address. This currently depends on the pfn, so pfn 5212 occupies a different vmacache slot than its neighboring pfn 5213. vmacache_find() iterates through all four of current's vmacache slots when looking up an address. Hashing based on pfn, an address has ~1/VMACACHE_SIZE chance of being cached in the first vmacache slot, or about 25%, *if* the vma is cached. This patch hashes an address by its pmd instead of pte to optimize for workloads with good spatial locality. This results in a higher probability of vmas being cached in the first slot that is checked: normally ~70% on the same workloads instead of 25%.

mm/list_lru: introduce list_lru_shrink_walk_irq()
Provide list_lru_shrink_walk_irq() and let it behave like list_lru_walk_one() except that it locks the spinlock with spin_lock_irq(). This is used by scan_shadow_nodes() because its lock nests within the i_pages lock which is acquired with IRQ. This change allows to use proper locking promitives instead hand crafted lock_irq_disable() plus spin_lock(). There is no EXPORT_SYMBOL provided because the current user is in-kernel only. Add list_lru_shrink_walk_irq() which acquires the spinlock with the proper locking primitives.

__list_lru_walk_one() is invoked with struct list_lru *lru, int nid as the first two argument. Those two are only used to retrieve struct list_lru_node. Since this is already done by the caller of the function for the locking, we can pass struct list_lru_node* directly and avoid the dance around it.

mm/list_lru.c: use list_lru_walk_one() in list_lru_walk_node()
Patch series "mm/list_lru: Add list_lru_shrink_walk_irq() and a user". This series removes the local_irq_disable() around list_lru_shrink_walk() (as used by mm/workingset) by adding list_lru_shrink_walk_irq(). Vladimir Davydov preferred this over `irq' argument which I added to struct list_lru. The initial post (of this series) received a Reviewed-by tag by Vladimir Davydov which I added to each patch of the series. The series applies on top of akpm's tree which has Kirill's shrink_slab series and does not clash with it (akpm asked me to wait a week or so and repost it then). I tested the code paths by triggering the OOM-killer via memory over commit and lockdep did not complain (nor did I see any warnings). This patch (of 4): list_lru_walk_node() invokes __list_lru_walk_one() with -1 as the memcg_idx parameter. The same can be achieved by list_lru_walk_one() and passing NULL as memcg argument which then gets converted into -1. This is a preparation step when the spin_lock() function is lifted to the caller of __list_lru_walk_one(). Invoke list_lru_walk_one() instead __list_lru_walk_one() when possible.

mm, swap: make CONFIG_THP_SWAP depend on CONFIG_SWAP
CONFIG_THP_SWAP should depend on CONFIG_SWAP, because it's unreasonable
to optimize swapping for THP (Transparent Huge Page) without basic
swapping support.
In original code, when CONFIG_SWAP=n and CONFIG_THP_SWAP=y,
split_swap_cluster() will not be built because it is in swapfile.c, but
it will be called in huge_memory.c. This doesn't trigger a build error
in practice because the call site is enclosed by PageSwapCache(), which
is defined to be constant 0 when CONFIG_SWAP=n. But this is fragile and
should be fixed.
The comments are fixed too to reflect the latest progress.
