     desired (Nicholas Johnson)

   - Only enforce bus numbers from bridge EA if the bridge has EA
     devices downstream (Subbaraya Sundeep)

   - Consolidate DT "dma-ranges" parsing and convert all host drivers to
     use shared parsing (Rob Herring)

  Error reporting:

   - Add PoisonTLPBlocked AER counter (Rajat Jain)

   - Use for_each_set_bit() to simplify AER code (Andy Shevchenko)

   - Fix AER kernel-doc (Andy Shevchenko)

   - Add "pcie_ports=dpc-native" parameter to allow native use of DPC
     even if platform didn't grant control over AER (Olof Johansson)

  Hotplug:

   - Avoid returning prematurely from sysfs requests to enable or
     disable a PCIe hotplug slot (Lukas Wunner)

   - Don't disable interrupts twice when suspending hotplug ports (Mika
     Westerberg)

   - Fix deadlocks when PCIe ports are hot-removed while suspended (Mika
     Westerberg)

   - Fix incorrect MSI-X masking on resume and revert related nvme quirk
     for Kingston NVME SSD running FW E8FK11.T (Jian-Hong Pan)

   - Always return devices to D0 when thawing to fix hibernation with
     drivers like mlx4 that used legacy power management (previously we

     Helgaas)

   - Removed unused .resume_early() and .suspend_late() legacy power
     management hooks (Bjorn Helgaas)

   - Decode power states more clearly ("4" or "D4" really refers to
     "D3cold") (Bjorn Helgaas)

   - Notice when reading PM Control register returns an error (~0)
     instead of interpreting it as being in D3hot (Bjorn Helgaas)

   - Add missing link delays required by the PCIe spec (Mika Westerberg)

  Virtualization:

   - Move pci_prg_resp_pasid_required() to CONFIG_PCI_PRI (Bjorn

   - Allow VFs to use PRI (the PF PRI is shared by the VFs, but the code
     previously didn't recognize that) (Kuppuswamy Sathyanarayanan)

   - Allow VFs to use PASID (the PF PASID capability is shared by the
     VFs, but the code previously didn't recognize that) (Kuppuswamy
     Sathyanarayanan)

   - Disconnect PF and VF ATS enablement, since ATS in PFs and
     associated VFs can be enabled independently (Kuppuswamy
     Sathyanarayanan)

   - Cache PRI and PASID capability offsets (Kuppuswamy Sathyanarayanan)

   - Cache the PRI PRG Response PASID Required bit (Bjorn Helgaas)

   - Consolidate ATS declarations in linux/pci-ats.h (Krzysztof
     Wilczynski)

   - Remove unused PRI and PASID stubs (Bjorn Helgaas)

   - Removed unnecessary EXPORT_SYMBOL_GPL() from ATS, PRI, and PASID
     interfaces that are only used by built-in IOMMU drivers (Bjorn

     PCI core (Bjorn Helgaas)

   - Add a DMA alias quirk for the Intel VCA NTB (Slawomir Pawlowski)

   - Serialize sysfs sriov_numvfs reads vs writes (Pierre Crégut)

   - Update Cavium ACS quirk for ThunderX2 and ThunderX3 (George
     Cherian)

   - Fix the UPDCR register address in the Intel ACS quirk (Steffen
     Liebergeld)

     implement the Link Training bit (Remi Pommarel)

   - Delay before training Aardvark link in case PERST# was asserted
     before the driver probe (Remi Pommarel)

   - Fix Aardvark issues with Root Control reads and writes (Remi
     Pommarel)

   - Don't rely on jiffies in Aardvark config access path since
     interrupts may be disabled (Remi Pommarel)

   - Fix Aardvark big-endian support (Grzegorz Jaszczyk)

a1b39bae16 asm-generic: Make msi.h a mandatory include/asm header
msi.h is generic for all architectures except x86, which has its own
version.  Enabling MSI by adding msi.h to every architecture's Kbuild is
just an additional step which doesn't need to be done.

Make msi.h mandatory in the asm-generic/Kbuild so we don't have to do it
for each architecture.

1bf883c1a9 y2038: stat: avoid 'time_t' in 'struct stat'
The time_t definition may differ between user space and kernel space,
so replace time_t with an unambiguous 'long' for the mips and sparc.

The same structures also contain 'off_t', which has the same problem,
so replace that as well on those two architectures and powerpc.

caf5e32d4e y2038: ipc: remove __kernel_time_t reference from headers
There are two structures based on time_t that conflict between libc and
kernel: timeval and timespec. Both are now renamed to __kernel_old_timeval
and __kernel_old_timespec.

For time_t, the old typedef is still __kernel_time_t. There is nothing
wrong with that name, but it would be nice to not use that going forward
as this type is used almost only in deprecated interfaces because of
the y2038 overflow.

In the IPC headers (msgbuf.h, sembuf.h, shmbuf.h), __kernel_time_t is only
used for the 64-bit variants, which are not deprecated.

Change these to a plain 'long', which is the same type as __kernel_time_t
on all 64-bit architectures anyway, to reduce the number of users of the
old type.

903f433f8f lib: untag user pointers in strn*_user
Patch series "arm64: untag user pointers passed to the kernel", v19.

=== Overview

arm64 has a feature called Top Byte Ignore, which allows to embed pointer
tags into the top byte of each pointer.  Userspace programs (such as
HWASan, a memory debugging tool [1]) might use this feature and pass
tagged user pointers to the kernel through syscalls or other interfaces.

Right now the kernel is already able to handle user faults with tagged
pointers, due to these patches:

1. 81cddd65 ("arm64: traps: fix userspace cache maintenance emulation on a
             tagged pointer")
2. 7dcd9dd8 ("arm64: hw_breakpoint: fix watchpoint matching for tagged
	      pointers")
3. 276e9327 ("arm64: entry: improve data abort handling of tagged
	      pointers")

This patchset extends tagged pointer support to syscall arguments.

As per the proposed ABI change [3], tagged pointers are only allowed to be
passed to syscalls when they point to memory ranges obtained by anonymous
mmap() or sbrk() (see the patchset [3] for more details).

For non-memory syscalls this is done by untaging user pointers when the
kernel performs pointer checking to find out whether the pointer comes
from userspace (most notably in access_ok).  The untagging is done only
when the pointer is being checked, the tag is preserved as the pointer
makes its way through the kernel and stays tagged when the kernel
dereferences the pointer when perfoming user memory accesses.

The mmap and mremap (only new_addr) syscalls do not currently accept
tagged addresses.  Architectures may interpret the tag as a background
colour for the corresponding vma.

Other memory syscalls (mprotect, etc.) don't do user memory accesses but
rather deal with memory ranges, and untagged pointers are better suited to
describe memory ranges internally.  Thus for memory syscalls we untag
pointers completely when they enter the kernel.

=== Other approaches

One of the alternative approaches to untagging that was considered is to
completely strip the pointer tag as the pointer enters the kernel with
some kind of a syscall wrapper, but that won't work with the countless
number of different ioctl calls.  With this approach we would need a
custom wrapper for each ioctl variation, which doesn't seem practical.

An alternative approach to untagging pointers in memory syscalls prologues
is to inspead allow tagged pointers to be passed to find_vma() (and other
vma related functions) and untag them there.  Unfortunately, a lot of
find_vma() callers then compare or subtract the returned vma start and end
fields against the pointer that was being searched.  Thus this approach
would still require changing all find_vma() callers.

=== Testing

The following testing approaches has been taken to find potential issues
with user pointer untagging:

1. Static testing (with sparse [2] and separately with a custom static
   analyzer based on Clang) to track casts of __user pointers to integer
   types to find places where untagging needs to be done.

2. Static testing with grep to find parts of the kernel that call
   find_vma() (and other similar functions) or directly compare against
   vm_start/vm_end fields of vma.

3. Static testing with grep to find parts of the kernel that compare
   user pointers with TASK_SIZE or other similar consts and macros.

4. Dynamic testing: adding BUG_ON(has_tag(addr)) to find_vma() and running
   a modified syzkaller version that passes tagged pointers to the kernel.

Based on the results of the testing the requried patches have been added
to the patchset.

=== Notes

This patchset is meant to be merged together with "arm64 relaxed ABI" [3].

This patchset is a prerequisite for ARM's memory tagging hardware feature
support [4].

This patchset has been merged into the Pixel 2 & 3 kernel trees and is
now being used to enable testing of Pixel phones with HWASan.

This patch (of 11)

This patch is a part of a series that extends kernel ABI to allow to pass
tagged user pointers (with the top byte set to something else other than
0x00) as syscall arguments.

strncpy_from_user and strnlen_user accept user addresses as arguments, and
do not go through the same path as copy_from_user and others, so here we
need to handle the case of tagged user addresses separately.

Untag user pointers passed to these functions.

Note, that this patch only temporarily untags the pointers to perform
validity checks, but then uses them as is to perform user memory accesses.

782de70c42 mm: consolidate pgtable_cache_init() and pgd_cache_init()
Both pgtable_cache_init() and pgd_cache_init() are used to initialize kmem
cache for page table allocations on several architectures that do not use
PAGE_SIZE tables for one or more levels of the page table hierarchy.

Most architectures do not implement these functions and use __weak default
NOP implementation of pgd_cache_init().  Since there is no such default
for pgtable_cache_init(), its empty stub is duplicated among most
architectures.

Rename the definitions of pgd_cache_init() to pgtable_cache_init() and
drop empty stubs of pgtable_cache_init().

13224794cb mm: remove quicklist page table caches
Patch series "mm: remove quicklist page table caches".

A while ago Nicholas proposed to remove quicklist page table caches [1].

I've rebased his patch on the curren upstream and switched ia64 and sh to
use generic versions of PTE allocation.

[1] https://lore.kernel.org/linux-mm/20190711030339.20892-1-npiggin@gmail.com

This patch (of 3):

Remove page table allocator "quicklists".  These have been around for a
long time, but have not got much traction in the last decade and are only
used on ia64 and sh architectures.

The numbers in the initial commit look interesting but probably don't
apply anymore.  If anybody wants to resurrect this it's in the git
history, but it's unhelpful to have this code and divergent allocator
behaviour for minor archs.

Also it might be better to instead make more general improvements to page
allocator if this is still so slow.

b8074aa246 PCI: Convert pci_resource_to_user() to a weak function
Convert pci_resource_to_user() to a weak function so the existing
architecture-specific implementations will automatically override the
generic one.  This allows us to remove HAVE_ARCH_PCI_RESOURCE_TO_USER
definitions and avoid the conditional compilation for this single function.

d9c5252295 treewide: add "WITH Linux-syscall-note" to SPDX tag of uapi headers
UAPI headers licensed under GPL are supposed to have exception
"WITH Linux-syscall-note" so that they can be included into non-GPL
user space application code.

The exception note is missing in some UAPI headers.

Some of them slipped in by the treewide conversion commit b24413180f
("License cleanup: add SPDX GPL-2.0 license identifier to files with
no license"). Just run:

  $ git show --oneline b24413180f -- arch/x86/include/uapi/asm/

I believe they are not intentional, and should be fixed too.

This patch was generated by the following script:

  git grep -l --not -e Linux-syscall-note --and -e SPDX-License-Identifier \
    -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild |
  while read file
  do
          sed -i -e '/[[:space:]]OR[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
          -e '/[[:space:]]or[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
          -e '/[[:space:]]OR[[:space:]]/!{/[[:space:]]or[[:space:]]/!s/\(GPL-[^[:space:]]*\)/\1 WITH Linux-syscall-note/g}' $file
  done

After this patch is applied, there are 5 UAPI headers that do not contain
"WITH Linux-syscall-note". They are kept untouched since this exception
applies only to GPL variants.

e192832869 Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar:
 "The main changes in this cycle are:

   - rwsem scalability improvements, phase #2, by Waiman Long, which are
     rather impressive:

       "On a 2-socket 40-core 80-thread Skylake system with 40 reader
        and writer locking threads, the min/mean/max locking operations
        done in a 5-second testing window before the patchset were:

         40 readers, Iterations Min/Mean/Max = 1,807/1,808/1,810
         40 writers, Iterations Min/Mean/Max = 1,807/50,344/151,255

        After the patchset, they became:

         40 readers, Iterations Min/Mean/Max = 30,057/31,359/32,741
         40 writers, Iterations Min/Mean/Max = 94,466/95,845/97,098"

     There's a lot of changes to the locking implementation that makes
     it similar to qrwlock, including owner handoff for more fair
     locking.

     Another microbenchmark shows how across the spectrum the
     improvements are:

       "With a locking microbenchmark running on 5.1 based kernel, the
        total locking rates (in kops/s) on a 2-socket Skylake system
        with equal numbers of readers and writers (mixed) before and
        after this patchset were:

        # of Threads   Before Patch      After Patch
        ------------   ------------      -----------
             2            2,618             4,193
             4            1,202             3,726
             8              802             3,622
            16              729             3,359
            32              319             2,826
            64              102             2,744"

     The changes are extensive and the patch-set has been through
     several iterations addressing various locking workloads. There
     might be more regressions, but unless they are pathological I
     believe we want to use this new implementation as the baseline
     going forward.

   - jump-label optimizations by Daniel Bristot de Oliveira: the primary
     motivation was to remove IPI disturbance of isolated RT-workload
     CPUs, which resulted in the implementation of batched jump-label
     updates. Beyond the improvement of the real-time characteristics
     kernel, in one test this patchset improved static key update
     overhead from 57 msecs to just 1.4 msecs - which is a nice speedup
     as well.

   - atomic64_t cross-arch type cleanups by Mark Rutland: over the last
     ~10 years of atomic64_t existence the various types used by the
     APIs only had to be self-consistent within each architecture -
     which means they became wildly inconsistent across architectures.
     Mark puts and end to this by reworking all the atomic64
     implementations to use 's64' as the base type for atomic64_t, and
     to ensure that this type is consistently used for parameters and
     return values in the API, avoiding further problems in this area.

   - A large set of small improvements to lockdep by Yuyang Du: type
     cleanups, output cleanups, function return type and othr cleanups
     all around the place.

   - A set of percpu ops cleanups and fixes by Peter Zijlstra.

   - Misc other changes - please see the Git log for more details"

99f3a064bc bpf: net: Add SO_DETACH_REUSEPORT_BPF
There is SO_ATTACH_REUSEPORT_[CE]BPF but there is no DETACH.
This patch adds SO_DETACH_REUSEPORT_BPF sockopt.  The same
sockopt can be used to undo both SO_ATTACH_REUSEPORT_[CE]BPF.

reseport_detach_prog() is added and it is mostly a mirror
of the existing reuseport_attach_prog().  The differences are,
it does not call reuseport_alloc() and returns -ENOENT when
there is no old prog.

15d5dfaf4a sparc: fix unknown type name u_int in uapi header
'u_int' is a shorthand that is only available in the kernel space
because it is defined in include/linux/types.h, which is not exported
to the user space.

You cannot use it in uapi headers even if you include <linux/types.h>

Detected by compile-testing exported headers.

04e8851af7 locking/atomic, sparc: Use s64 for atomic64
As a step towards making the atomic64 API use consistent types treewide,
let's have the sparc atomic64 implementation use s64 as the underlying
type for atomic64_t, rather than long, matching the generated headers.

As atomic64_read() depends on the generic defintion of atomic64_t, this
still returns long. This will be converted in a subsequent patch.

Otherwise, there should be no functional change as a result of this patch.

5470dea49f mm: use mm_zero_struct_page from SPARC on all 64b architectures
Patch series "Deferred page init improvements", v7.

This patchset is essentially a refactor of the page initialization logic
that is meant to provide for better code reuse while providing a
significant improvement in deferred page initialization performance.

In my testing on an x86_64 system with 384GB of RAM I have seen the
following.  In the case of regular memory initialization the deferred init
time was decreased from 3.75s to 1.38s on average.  This amounts to a 172%
improvement for the deferred memory initialization performance.

I have called out the improvement observed with each patch.

This patch (of 4):

Use the same approach that was already in use on Sparc on all the
architectures that support a 64b long.

This is mostly motivated by the fact that 7 to 10 store/move instructions
are likely always going to be faster than having to call into a function
that is not specialized for handling page init.

An added advantage to doing it this way is that the compiler can get away
with combining writes in the __init_single_page call.  As a result the
memset call will be reduced to only about 4 write operations, or at least
that is what I am seeing with GCC 6.2 as the flags, LRU pointers, and
count/mapcount seem to be cancelling out at least 4 of the 8 assignments
on my system.

One change I had to make to the function was to reduce the minimum page
size to 56 to support some powerpc64 configurations.

This change should introduce no change on SPARC since it already had this
code.  In the case of x86_64 I saw a reduction from 3.75s to 2.80s when
initializing 384GB of RAM per node.  Pavel Tatashin tested on a system
with Broadcom's Stingray CPU and 48GB of RAM and found that
__init_single_page() takes 19.30ns / 64-byte struct page before this patch
and with this patch it takes 17.33ns / 64-byte struct page.  Mike Rapoport
ran a similar test on a OpenPower (S812LC 8348-21C) with Power8 processor
and 128GB or RAM.  His results per 64-byte struct page were 4.68ns before,
and 4.59ns after this patch.

171c2bcbcb Merge branch 'core-mm-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull unified TLB flushing from Ingo Molnar:
 "This contains the generic mmu_gather feature from Peter Zijlstra,
  which is an all-arch unification of TLB flushing APIs, via the
  following (broad) steps:

   - enhance the <asm-generic/tlb.h> APIs to cover more arch details

   - convert most TLB flushing arch implementations to the generic
     <asm-generic/tlb.h> APIs.

   - remove leftovers of per arch implementations

  After this series every single architecture makes use of the unified
  TLB flushing APIs"

5ce5d8a5a4 asm-generic: generalize asm/sockios.h
ia64, parisc and sparc just use a copy of the generic version
of asm/sockios.h, and x86 is a redirect to the same file, so we
can just let the header file be generated.

01e3b958ef arch: Remove dummy mmiowb() definitions from arch code
Now that no driver code is using mmiowb() directly, remove the dummy
definitions remaining in architectures that don't make use of
asm-generic/io.h, as well as the definition in asm-generic/io.h itself.

fdcd06a8ab arch: Use asm-generic header for asm/mmiowb.h
Hook up asm-generic/mmiowb.h to Kbuild for all architectures so that we
can subsequently include asm/mmiowb.h from core code.

32d9258662 syscalls: Remove start and number from syscall_set_arguments() args
After removing the start and count arguments of syscall_get_arguments() it
seems reasonable to remove them from syscall_set_arguments(). Note, as of
today, there are no users of syscall_set_arguments(). But we are told that
there will be soon. But for now, at least make it consistent with
syscall_get_arguments().

b35f549df1 syscalls: Remove start and number from syscall_get_arguments() args
At Linux Plumbers, Andy Lutomirski approached me and pointed out that the
function call syscall_get_arguments() implemented in x86 was horribly
written and not optimized for the standard case of passing in 0 and 6 for
the starting index and the number of system calls to get. When looking at
all the users of this function, I discovered that all instances pass in only
0 and 6 for these arguments. Instead of having this function handle
different cases that are never used, simply rewrite it to return the first 6
arguments of a system call.

This should help out the performance of tracing system calls by ptrace,
ftrace and perf.
