The encoding of the pkey register differs on arm64, than on x86/ppc. On those
platforms, a bit in the register is used to disable permissions, for arm64, a
bit enabled in the register indicates that the permission is allowed.

This drops two asserts of the form:
	 assert(read_pkey_reg() <= orig_pkey_reg);
Because on arm64 this doesn't hold, due to the encoding.

The pkey must be reset to both access allow and write allow in the signal
handler. pkey_access_allow() works currently for PowerPC as the
PKEY_DISABLE_ACCESS and PKEY_DISABLE_WRITE have overlapping bits set.

Access to the uc_mcontext is abstracted, as arm64 has a different structure.

Permission Indirection Extension and Permission Overlay Extension can be
enabled independently.

When PIE is disabled and POE is enabled, the permissions set by POR_EL0 will be
applied on top of the permissions set in the PTE.

When both PIE and POE are enabled, the permissions set by POR_EL0 will be
applied on top of the permissions set by the PIRE0_EL1 register.
However PIRE0_EL1 has encodings that specifically enable and disable the
overlay from applying.

For example:
	0001	Read, Overlay applied.
	1000	Read, Overlay not applied.

Switch to using the 'Overlay applied' encodings in PIRE0_EL1, so that PIE and
POE can coexist.

Pull x86 fixes from Thomas Gleixner:

 - Fix 32-bit PTI for real.

   pti_clone_entry_text() is called twice, once before initcalls so that
   initcalls can use the user-mode helper and then again after text is
   set read only. Setting read only on 32-bit might break up the PMD
   mapping, which makes the second invocation of pti_clone_entry_text()
   find the mappings out of sync and failing.

   Allow the second call to split the existing PMDs in the user mapping
   and synchronize with the kernel mapping.

 - Don't make acpi_mp_wake_mailbox read-only after init as the mail box
   must be writable in the case that CPU hotplug operations happen after
   boot. Otherwise the attempt to start a CPU crashes with a write to
   read only memory.

 - Add a missing sanity check in mtrr_save_state() to ensure that the
   fixed MTRR MSRs are supported.

   Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but
   the WARN_ON() can bring systems down when panic on warn is set.

Pull time keeping fixes from Thomas Gleixner:

 - Fix a couple of issues in the NTP code where user supplied values are
   neither sanity checked nor clamped to the operating range. This
   results in integer overflows and eventualy NTP getting out of sync.

   According to the history the sanity checks had been removed in favor
   of clamping the values, but the clamping never worked correctly under
   all circumstances. The NTP people asked to not bring the sanity
   checks back as it might break existing applications.

   Make the clamping work correctly and add it where it's missing

 - If adjtimex() sets the clock it has to trigger the hrtimer subsystem
   so it can adjust and if the clock was set into the future expire
   timers if needed. The caller should provide a bitmask to tell
   hrtimers which clocks have been adjusted.

   adjtimex() uses not the proper constant and uses CLOCK_REALTIME
   instead, which is 0. So hrtimers adjusts only the clocks, but does
   not check for expired timers, which might make them expire really
   late. Use the proper bitmask constant instead.
