Subject: [GIT PULL] arm64 updates for 5.13-rc1 (2nd set)

Hi Linus,

Please pull the arm64 updates below. They contain a mix of fixes and
clean-ups that turned up too late for the first pull request this
merging window. There is a trivial conflict in alternative.c, my
resolution is at the end of this email.

Thanks.

The following changes since commit a27a8816568964fcef62a3ae5f9d2228ec1ebc68:

  arm64: kernel: Update the stale comment (2021-05-06 12:26:26 +0100)

----------------------------------------------------------------
Assorted arm64 fixes and clean-ups, the most important:

- Restore terminal stack frame records. Their previous removal caused
  traces which cross secondary_start_kernel to terminate one entry too
  late, with a spurious "0" entry.

- Fix boot warning with pseudo-NMI due to the way we manipulate the PMR
  register.

- ACPI fixes: avoid corruption of interrupt mappings on watchdog probe
  failure (GTDT), prevent unregistering of GIC SGIs.

- Force SPARSEMEM_VMEMMAP as the only memory model, it saves with having
  to test all the other combinations.

- Documentation fixes and updates: tagged address ABI exceptions on
  brk/mmap/mremap(), event stream frequency, update booting requirements
  on the configuration of traps.
