gpio: mpc8xxx: Fix a potential double iounmap call in 'mpc8xxx_probe()'

Commit 76c47d1449fc ("gpio: mpc8xxx: Add ACPI support") has switched to a
managed version when dealing with 'mpc8xxx_gc->regs'. So the corresponding
'iounmap()' call in the error handling path and in the remove should be
removed to avoid a double unmap.

This also allows some simplification in the probe. All the error handling
paths related to managed resources can be direct returns and a NULL check
in what remains in the error handling path can be removed.

mm/rmap: fix old bug: munlocking THP missed other mlocks

The kernel recovers in due course from missing Mlocked pages: but there
was no point in calling page_mlock() (formerly known as
try_to_munlock()) on a THP, because nothing got done even when it was
found to be mapped in another VM_LOCKED vma.

It's true that we need to be careful: Mlocked accounting of pte-mapped
THPs is too difficult (so consistently avoided); but Mlocked accounting
of only-pmd-mapped THPs is supposed to work, even when multiple mappings
are mlocked and munlocked or munmapped.  Refine the tests.

There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so
page_mlock_one() does not even have to worry about that complication.

(I said the kernel recovers: but would page reclaim be likely to split
THP before rediscovering that it's VM_LOCKED? I've not followed that up)

Merge tag 'perf-tools-for-v5.14-2021-07-10' of git://git./linux/kernel/git/acme/linux

Pull more perf tool updates from Arnaldo Carvalho de Melo:
 "New features:

   - Enable use of BPF counters with 'perf stat --for-each-cgroup',
     using per-CPU 'cgroup-switch' events with an attached BPF program
     that does aggregation per-cgroup in the kernel instead of using
     per-cgroup perf events.

   - Add Topdown metrics L2 events as default events in 'perf stat' for
     systems having those events.

  Hardware tracing:

   - Add a config for max loops without consuming a packet in the Intel
     PT packet decoder, set via 'perf config intel-pt.max-loops=N'

  Hardware enablement:

   - Disable misleading NMI watchdog message in 'perf stat' on hybrid
     systems such as Intel Alder Lake.

   - Add a dummy event on hybrid systems to collect metadata records.

   - Add 24x7 nest metric events for the Power10 platform.

  Fixes:

   - Fix event parsing for PMUs starting with the same prefix.

   - Fix the 'perf trace' 'trace' alias installation dir.

   - Fix buffer size to report iregs in perf script python scripts,
     supporting the extended registers in PowerPC.

   - Fix overflow in elf_sec__is_text().

   - Fix 's' on source line when disasm is empty in the annotation TUI,
     accessible via 'perf annotate', 'perf report' and 'perf top'.

   - Plug leaks in scandir() returned dirent entries in 'perf test' when
     sorting the shell tests.

   - Fix --task and --stat with pipe input in 'perf report'.

   - Fix 'perf probe' use of debuginfo files by build id.

   - If a DSO has both dynsym and symtab ELF sections, read from both
     when loading the symbol table, fixing a problem processing Fedora
     32 glibc DSOs.

  Libraries:

   - Add grouping of events to libperf, from code in tools/perf,
     allowing libperf users to use that mode.

  Misc:

   - Filter plt stubs from the 'perf probe --functions' output.

   - Update UAPI header copies for asound, DRM, mman-common.h and the
     ones affected by the quotactl_fd syscall"

added support for timestamp interrupts. However they are not being
handled in the irq handler. If a timestamp interrupt occurs it
results in kernel disabling the interrupt and displaying the call
trace:

[  121.248971] Disabling IRQ #78

Handle timestamp interrupts in pcf2127_rtc_irq(). Save time stamp
before clearing TSF1 and TSF2 flags so that it can't be overwritten.
Set a flag to mark if the timestamp is valid and only report to sysfs
if the flag is set. To mimic the hardware behavior, don’t save
another timestamp until the first one has been read by the userspace.

However, if the alarm irq is not configured, keep the old way of
handling timestamp interrupt in the timestamp0 sysfs calls.

SMB3.1.1: Add support for negotiating signing algorithm

Support for faster packet signing (using GMAC instead of CMAC) can
now be negotiated to some newer servers, including Windows.
See MS-SMB2 section 2.2.3.17.

This patch adds support for sending the new negotiate context
with the first of three supported signing algorithms (AES-CMAC)
and decoding the response.  A followon patch will add support
for sending the other two (including AES-GMAC, which is fastest)
and changing the signing algorithm used based on what was
negotiated.

To allow the client to request GMAC signing set module parameter
"enable_negotiate_signing" to 1.
