My fix for a recursive Kconfig dependency caused another issue where the
ACPI specific options end up in the top-level menu in 'menuconfig'. This
was an unintended side-effect of having a silent option between
'menuconfig ACPI' and 'if ACPI'.

Moving the ARCH_SUPPORTS_ACPI symbol ahead of the ACPI menu solves that
problem and restores the previous presentation.

  ACPI / PMIC: CrystalCove: Extend PMOP support to support all possible fields

This is unnecessary and triggers a warning in the hypervisor.

Often systems have more processor entries in their ACPI tables than are
actually installed/active. The ACPI_STA_DEVICE_PRESENT bit cannot be
reliably used, but the ACPI_MADT_ENABLED bit can. In order to not
introduce new functions in the main ACPI processor driver code, simply
use acpi_get_phys_id(), which does more than we need, but which checks
the MADT enabled bit in the process. Any CPU for which we can't
determine the APIC ID is unlikely to work properly anyway, so the extra
checks done by acpi_get_phys_id() should do no harm.

Pull arm64 updates from Will Deacon:
 "A bunch of good stuff in here. Worth noting is that we've pulled in
  the x86/mm branch from -tip so that we can make use of the core
  ioremap changes which allow us to put down huge mappings in the
  vmalloc area without screwing up the TLB. Much of the positive
  diffstat is because of the rseq selftest for arm64.

  Summary:

   - Wire up support for qspinlock, replacing our trusty ticket lock
     code

   - Add an IPI to flush_icache_range() to ensure that stale
     instructions fetched into the pipeline are discarded along with the
     I-cache lines

   - Support for the GCC "stackleak" plugin

   - Support for restartable sequences, plus an arm64 port for the
     selftest

   - Kexec/kdump support on systems booting with ACPI

   - Rewrite of our syscall entry code in C, which allows us to zero the
     GPRs on entry from userspace

   - Support for chained PMU counters, allowing 64-bit event counters to
     be constructed on current CPUs

   - Ensure scheduler topology information is kept up-to-date with CPU
     hotplug events

   - Re-enable support for huge vmalloc/IO mappings now that the core
     code has the correct hooks to use break-before-make sequences

   - Miscellaneous, non-critical fixes and cleanups"

PMOP fields. Leading to errors like these on device using the VBUS field:

Commit fa85015c0d95 (ACPICA: Clear status of all events when entering
S5) made the sleep state entry code in ACPICA clear the status of all
ACPI events when entering S5 to fix a functional regression reported
against commit 18996f2db918 (ACPICA: Events: Stop unconditionally
clearing ACPI IRQs during suspend/resume).  However, it is reported
now that the regression also affects system states other than S5 on
some systems and causes them to wake up from sleep prematurely.

For this reason, make the code in question clear the status of all
ACPI events when entering all sleep states (in addition to S5) to
avoid the premature wakeups (this may cause some wakeup events to
be missed in theory, but the likelihood of that is small and the
change here simply restores the previous behavior of the code).
