bac65d9d87 powerpc updates for 4.14
Nothing really major this release, despite quite a lot of activity. Just lots of
 things all over the place.
 
 Some things of note include:
 
  - Access via perf to a new type of PMU (IMC) on Power9, which can count both
    core events as well as nest unit events (Memory controller etc).
 
  - Optimisations to the radix MMU TLB flushing, mostly to avoid unnecessary Page
    Walk Cache (PWC) flushes when the structure of the tree is not changing.
 
  - Reworks/cleanups of do_page_fault() to modernise it and bring it closer to
    other architectures where possible.
 
  - Rework of our page table walking so that THP updates only need to send IPIs
    to CPUs where the affected mm has run, rather than all CPUs.
 
  - The size of our vmalloc area is increased to 56T on 64-bit hash MMU systems.
    This avoids problems with the percpu allocator on systems with very sparse
    NUMA layouts.
 
  - STRICT_KERNEL_RWX support on PPC32.
 
  - A new sched domain topology for Power9, to capture the fact that pairs of
    cores may share an L2 cache.
 
  - Power9 support for VAS, which is a new mechanism for accessing coprocessors,
    and initial support for using it with the NX compression accelerator.
 
  - Major work on the instruction emulation support, adding support for many new
    instructions, and reworking it so it can be used to implement the emulation
    needed to fixup alignment faults.
 
  - Support for guests under PowerVM to use the Power9 XIVE interrupt controller.
 
 And probably that many things again that are almost as interesting, but I had to
 keep the list short. Plus the usual fixes and cleanups as always.

Pull EFI updates from Ingo Molnar:
 "The main changes in this cycle were:

   - Transparently fall back to other poweroff method(s) if EFI poweroff
     fails (and returns)

   - Use separate PE/COFF section headers for the RX and RW parts of the
     ARM stub loader so that the firmware can use strict mapping
     permissions

   - Add support for requesting the firmware to wipe RAM at warm reboot

   - Increase the size of the random seed obtained from UEFI so CRNG
     fast init can complete earlier

   - Update the EFI framebuffer address if it points to a BAR that gets
     moved by the PCI resource allocation code

   - Enable "reset attack mitigation" of TPM environments: this is
     enabled if the kernel is configured with
     CONFIG_RESET_ATTACK_MITIGATION=y.

   - Clang related fixes

   - Misc cleanups, constification, refactoring, etc"

2eabc84d2f iwlwifi: mvm: only send LEDS_CMD when the FW supports it
The LEDS_CMD command is only supported in some newer FW versions
(e.g. iwlwifi-8000C-31.ucode), so we can't send it to older versions
(such as iwlwifi-8000C-27.ucode).

To fix this, check for a new bit in the FW capabilities TLV that tells
when the command is supported.

Note that the current version of -31.ucode in linux-firmware.git
(31.532993.0) does not have this capability bit set, so the LED won't
work, even though this version should support it.  But we will update
this firmware soon, so it won't be a problem anymore.

KVM/PPC update for 4.14

There are various minor fixes and cleanups.  The only new feature is
that we now export information about storage key support to userspace,
so it can advertise it to the guest.

I have pulled in Michael Ellerman's topic/ppc-kvm branch from the
powerpc tree to get a couple of fixes that touch both KVM PPC code and
other PPC code.  That's why there is some arch/powerpc stuff in the
diffstat that isn't arch/powerpc/kvm.

2a8a98673c fs: aio: fix the increment of aio-nr and counting against aio-max-nr
Currently, aio-nr is incremented in steps of 'num_possible_cpus() * 8'
for io_setup(nr_events, ..) with 'nr_events < num_possible_cpus() * 4':

    ioctx_alloc()
    ...
        nr_events = max(nr_events, num_possible_cpus() * 4);
        nr_events *= 2;
    ...
        ctx->max_reqs = nr_events;
    ...
        aio_nr += ctx->max_reqs;
    ....

This limits the number of aio contexts actually available to much less
than aio-max-nr, and is increasingly worse with greater number of CPUs.

For example, with 64 CPUs, only 256 aio contexts are actually available
(with aio-max-nr = 65536) because the increment is 512 in that scenario.

Note: 65536 [max aio contexts] / (64*4*2) [increment per aio context]
is 128, but make it 256 (double) as counting against 'aio-max-nr * 2':

    ioctx_alloc()
    ...
        if (aio_nr + nr_events > (aio_max_nr * 2UL) ||
        ...
            goto err_ctx;
    ...

This patch uses the original value of nr_events (from userspace) to
increment aio-nr and count against aio-max-nr, which resolves those.

e973b1a599 NFS: Sync the correct byte range during synchronous writes
Since commit 18290650b1 ("NFS: Move buffered I/O locking into
nfs_file_write()") nfs_file_write() has not flushed the correct byte
range during synchronous writes.  generic_write_sync() expects that
iocb->ki_pos points to the right edge of the range rather than the
left edge.

To replicate the problem, open a file with O_DSYNC, have the client
write at increasing offsets, and then print the successful offsets.
Block port 2049 partway through that sequence, and observe that the
client application indicates successful writes in advance of what the
server received.

21d9bb4a05 x86/mm: Make the SME mask a u64
The SME encryption mask is for masking 64-bit pagetable entries. It
being an unsigned long works fine on X86_64 but on 32-bit builds in
truncates bits leading to Xen guests crashing very early.

And regardless, the whole SME mask handling shouldnt've leaked into
32-bit because SME is X86_64-only feature. So, first make the mask u64.
And then, add trivial 32-bit versions of the __sme_* macros so that
nothing happens there.

50e7663233 sched/cpuset/pm: Fix cpuset vs. suspend-resume bugs
Cpusets vs. suspend-resume is _completely_ broken. And it got noticed
because it now resulted in non-cpuset usage breaking too.

On suspend cpuset_cpu_inactive() doesn't call into
cpuset_update_active_cpus() because it doesn't want to move tasks about,
there is no need, all tasks are frozen and won't run again until after
we've resumed everything.

But this means that when we finally do call into
cpuset_update_active_cpus() after resuming the last frozen cpu in
cpuset_cpu_active(), the top_cpuset will not have any difference with
the cpu_active_mask and this it will not in fact do _anything_.

So the cpuset configuration will not be restored. This was largely
hidden because we would unconditionally create identity domains and
mobile users would not in fact use cpusets much. And servers what do use
cpusets tend to not suspend-resume much.

An addition problem is that we'd not in fact wait for the cpuset work to
finish before resuming the tasks, allowing spurious migrations outside
of the specified domains.

Fix the rebuild by introducing cpuset_force_rebuild() and fix the
ordering with cpuset_wait_for_hotplug().
