 "Fixup for arch/score after extable.h introduction.

  It seems that Guenter is the only one on the planet doing builds for
  arch/score -- we don't have compile coverage for it in linux-next or
  in the kbuild-bot either. Guenter couldn't even recall where he got
  his toolchain, but was kind enough to share it with me so I could
  validate this change and also add arch/score to my build coverage.

  I sat on this a bit in case there was any other fallout in other arch
  dirs, but since this still seems to be the only one, I might as well
  send it on its way"

This reverts commit 7b9f1d16e6 ("clocksource/drivers/tcb_clksrc: Use
32 bit tcb as sched_clock"). In the current state, the kernel warns
against a late registration of the new sched_clock, the printk clock
resets after only a few minutes, and it seems that scheduling can be
affected as well.

0acf611997 score: Fix implicit includes now failing build after extable change
After changing from module.h to extable.h, score builds fail with:

  arch/score/kernel/traps.c: In function 'do_ri':
  arch/score/kernel/traps.c:248:4: error: implicit declaration of function 'user_disable_single_step'

  arch/score/mm/extable.c:32:38: error: dereferencing pointer to incomplete type
  arch/score/mm/extable.c:34:24: error: dereferencing pointer to incomplete type

because extable.h doesn't drag in the same amount of headers as the
module.h did.  Add in the headers which were implicitly expected.

a77d6cd968 acpi/processor: Check for duplicate processor ids at hotplug time
The check for duplicate processor ids happens at boot time based on the
ACPI table contents, but the final sanity checks for a processor happen
at hotplug time.

At hotplug time, where the physical information is available, which might
differ from the ACPI table information, a check for duplicate processor
ids is missing.

Add it to the hotplug checks and rename the function so it better
reflects its purpose.

8c8cb30f49 acpi/processor: Implement DEVICE operator for processor enumeration
ACPI allows to declare processors either with the PROCESSOR or with the
DEVICE operator. The current implementation handles only the PROCESSOR
operator.

On a system which uses the DEVICE operator for processor enumeration the
evaluation fails.

Check for the ACPI type of the ACPI handle and evaluate PROCESSOR and
DEVICE types separately.

2b85b3d229 x86/acpi: Restore the order of CPU IDs
The following commits:

  f7c28833c2 ("x86/acpi: Enable acpi to register all possible cpus at
boot time") and 8f54969dc8 ("x86/acpi: Introduce persistent storage
for cpuid <-> apicid mapping")

... registered all the possible CPUs at boot time via ACPI tables to
make the mapping of cpuid <-> apicid fixed. Both enabled and disabled
CPUs could have a logical CPU ID after boot time.

But, ACPI tables are unreliable. the number amd order of Local APIC
entries which depends on the firmware is often inconsistent with the
physical devices. Even if they are consistent, The disabled CPUs which
take up some logical CPU IDs will also make the order discontinuous.

Revert the part of disabled CPUs registration, keep the allocation
logic of logical CPU IDs and also keep some code location changes.

c962cff17d Revert "x86/acpi: Set persistent cpuid <-> nodeid mapping when booting"
Revert: dc6db24d24 ("x86/acpi: Set persistent cpuid <-> nodeid mapping when booting")

The mapping of "cpuid <-> nodeid" is established at boot time via ACPI
tables to keep associations of workqueues and other node related items
consistent across cpu hotplug.

But, ACPI tables are unreliable and failures with that boot time mapping
have been reported on machines where the ACPI table and the physical
information which is retrieved at actual hotplug is inconsistent.

Revert the mapping implementation so it can be replaced with a less error
prone approach.

70b085b06c device-dax: fix pud fault fallback handling
Jeff Moyer reports:

    With a device dax alignment of 4KB or 2MB, I get sigbus when running
    the attached fio job file for the current kernel (4.11.0-rc1+).  If
    I specify an alignment of 1GB, it works.

    I turned on debug output, and saw that it was failing in the huge
    fault code.

     dax dax1.0: dax_open
     dax dax1.0: dax_mmap
     dax dax1.0: dax_dev_huge_fault: fio: write (0x7f08f0a00000 -
     dax dax1.0: __dax_dev_pud_fault: phys_to_pgoff(0xffffffffcf60)
     dax dax1.0: dax_release

    fio config for reproduce:
    [global]
    ioengine=dev-dax

    filename=/dev/dax0.0
    bs=2m

    [write]
    rw=write

    [read]
    stonewall
    rw=read

The driver fails to fallback when taking a fault that is larger than
the device alignment, or handling a larger fault when a smaller
mapping is already established. While we could support larger
mappings for a device with a smaller alignment, that change is
too large for the immediate fix. The simplest change is to force
fallback until the fault size matches the alignment.

EeeBook X205TA is yet another ASUS device with a special touchpad
firmware that needs to be accounted for during initialization, or
else the touchpad will go into an invalid state upon suspend/resume.
Adding the appropriate ic_type and product_id check fixes the problem.

800a938f0b NFSD: fix nfsd_reset_versions for NFSv4.
If you write "-2 -3 -4" to the "versions" file, it will
notice that no versions are enabled, and nfsd_reset_versions()
is called.
This enables all major versions, not no minor versions.
So we lose the invariant that NFSv4 is only advertised when
at least one minor is enabled.

Fix the code to explicitly enable minor versions for v4,
change it to use nfsd_vers() to test and set, and simplify
the code.

928c6fb3a9 NFSD: fix nfsd_minorversion(.., NFSD_AVAIL)
Current code will return 1 if the version is supported,
and -1 if it isn't.
This is confusing and inconsistent with the one place where this
is used.
So change to return 1 if it is supported, and zero if not.
i.e. an error is never returned.

abcb4dacb0 NFSD: further refinement of content of /proc/fs/nfsd/versions
Prior to
  e35659f1b0 ("NFSD: correctly range-check v4.x minor version when setting versions.")

v4.0 could not be disabled without disabling all NFSv4 protocols.
So the 'versions' file contained ±4 ±4.1 ±4.2.
Writing "-4" would disable all v4 completely.  Writing +4 would enabled those
minor versions that are currently enabled, either by default or otherwise.

After that commit, it was possible to disable v4.0 independently.  To
maximize backward compatibility with use cases which never disabled
v4.0, the "versions" file would never contain "+4.0" - that was implied
by "+4", unless explicitly negated by "-4.0".

This introduced an inconsistency in that it was possible to disable all
minor versions, but still have the major version advertised.
e.g. "-4.0 -4.1 -4.2 +4" would result in NFSv4 support being advertised,
but all attempts to use it rejected.

Commit
  d3635ff07e ("nfsd: fix configuration of supported minor versions")

and following removed this inconsistency. If all minor version were disabled,
the major would be disabled too.  If any minor was enabled, the major would be
disabled.
This patch also treated "+4" as equivalent to "+4.0" and "-4" as "-4.0".
A consequence of this is that writing "-4" would only disable 4.0.
This is a regression against the earlier behaviour, in a use case that rpc.nfsd
actually uses.
The command "rpc.nfsd -N 4" will write "+2 +3 -4" to the versions files.
Previously, that would disable v4 completely.  Now it will only disable v4.0.

Also "4.0" never appears in the "versions" file when read.
So if only v4.1 is available, the previous kernel would have reported
"+4 -4.0 +4.1 -4.2"  the current kernel reports "-4 +4.1 -4.2" which
could easily confuse.

This patch restores the implication that "+4" and "-4" apply more
globals and do not imply "4.0".
Specifically:
 writing "-4" will disable all 4.x minor versions.
 writing "+4" will enable all 4.1 minor version if none are currently enabled.
    rpc.nfsd will list minor versions before major versions, so
      rpc.nfsd -V 4.2 -N 4.1
    will write "-4.1 +4.2 +2 +3 +4"
    so it would be a regression for "+4" to enable always all versions.
 reading "-4" implies that no v4.x are enabled
 reading "+4" implies that some v4.x are enabled, and that v4.0 is enabled unless
 "-4.0" is also present.  All other minor versions will explicitly be listed.

40c50c1fec kexec, x86/purgatory: Unbreak it and clean it up
The purgatory code defines global variables which are referenced via a
symbol lookup in the kexec code (core and arch).

A recent commit addressing sparse warnings made these static and thereby
broke kexec_file.

Why did this happen? Simply because the whole machinery is undocumented and
lacks any form of forward declarations. The variable names are unspecific
and lack a prefix, so adding forward declarations creates shadow variables
in the core code. Aside of that the code relies on magic constants and
duplicate struct definitions with no way to ensure that these things stay
in sync. The section placement of the purgatory variables happened by
chance and not by design.

Unbreak kexec and cleanup the mess:

 - Add proper forward declarations and document the usage
 - Use common struct definition
 - Use the proper common defines instead of magic constants
 - Add a purgatory_ prefix to have a proper name space
 - Use ARRAY_SIZE() instead of a homebrewn reimplementation
 - Add proper sections to the purgatory variables [ From Mike ]

14088540ad arm64: use const cap for system_uses_ttbr0_pan()
Since commit 4b65a5db36 ("arm64: Introduce
uaccess_{disable,enable} functionality based on TTBR0_EL1"),
system_uses_ttbr0_pan() has used cpus_have_cap() to determine whether
PAN is present.

Since commit a4023f6827 ("arm64: Add hypervisor safe helper for
checking constant capabilities"), which was introduced around the same
time, cpus_have_cap() doesn't try to use a static key, and must always
perform a load, test, and consitional branch (likely a tbnz for the
latter two).

Elsewhere, we moved to using cpus_have_const_cap(), which can use a
static key (i.e. a non-conditional branch), which is patched at runtime
when the feature is detected.

This patch makes system_uses_ttbr0_pan() use cpus_have_const_cap(). The
static key is likely a win for hot-paths like the uacccess primitives,
and this makes our usage consistent regardless.

5c2a625937 arm64: support keyctl() system call in 32-bit mode
As is the case for a number of other architectures that have a 32-bit
compat mode, enable KEYS_COMPAT if both COMPAT and KEYS are enabled.
This allows AArch32 programs to use the keyctl() system call when
running on an AArch64 kernel.

b0de0ccc8b arm64: kasan: avoid bad virt_to_pfn()
Booting a v4.11-rc1 kernel with DEBUG_VIRTUAL and KASAN enabled produces
the following splat (trimmed for brevity):

[    0.000000] virt_to_phys used for non-linear address: ffff200008080000 (0xffff200008080000)
[    0.000000] WARNING: CPU: 0 PID: 0 at arch/arm64/mm/physaddr.c:14 __virt_to_phys+0x48/0x70

[    0.000000] Call trace:

[    0.000000] [<ffff20000a0301e8>] __primary_switched+0x6c/0x74

This is because we use virt_to_pfn() on a kernel image address when
trying to figure out its nid, so that we can allocate its shadow from
the same node.

As with other recent changes, this patch uses lm_alias() to solve this.

We could instead use NUMA_NO_NODE, as x86 does for all shadow
allocations, though we'll likely want the "real" memory shadow to be
backed from its corresponding nid anyway, so we may as well be
consistent and find the nid for the image shadow.

Commit fc62d0207a ("kprobes: Introduce weak variant of
kprobe_exceptions_notify()") introduces a generic empty version of the
function for architectures that don't need special handling, like arm64.
As such, remove the arch/arm64/ specific handler.

702f2ac87a rxrpc: Wake up the transmitter if Rx window size increases on the peer
The RxRPC ACK packet may contain an extension that includes the peer's
current Rx window size for this call.  We adjust the local Tx window size
to match.  However, the transmitter can stall if the receive window is
reduced to 0 by the peer and then reopened.

This is because the normal way that the transmitter is re-energised is by
dropping something out of our Tx queue and thus making space.  When a
single gap is made, the transmitter is woken up.  However, because there's
nothing in the Tx queue at this point, this doesn't happen.

To fix this, perform a wake_up() any time we see the peer's Rx window size
increasing.

The observable symptom is that calls start failing on ETIMEDOUT and the
following:

	kAFS: SERVER DEAD state=-62

appears in dmesg.

baeedc7158 Merge branch 'prep-for-5level'
Merge 5-level page table prep from Kirill Shutemov:
 "Here's relatively low-risk part of 5-level paging patchset. Merging it
  now will make x86 5-level paging enabling in v4.12 easier.

  The first patch is actually x86-specific: detect 5-level paging
  support. It boils down to single define.

  The rest of patchset converts Linux MMU abstraction from 4- to 5-level
  paging.

  Enabling of new abstraction in most cases requires adding single line
  of code in arch-specific code. The rest is taken care by asm-generic/.

  Changes to mm/ code are mostly mechanical: add support for new page
  table level -- p4d_t -- where we deal with pud_t now.

  v2:
   - fix build on microblaze (Michal);
   - comment for __ARCH_HAS_5LEVEL_HACK in kasan_populate_zero_shadow();
   - acks from Michal"
