  arm64: entry: refine comment of stack overflow check (2019-12-06 14:11:31 +0000)

----------------------------------------------------------------
arm64 updates for 5.5:

- ZONE_DMA32 initialisation fix when memblocks fall entirely within the
  first GB (used by ZONE_DMA in 5.5 for Raspberry Pi 4).

- Couple of ftrace fixes following the FTRACE_WITH_REGS patchset.

- access_ok() fix for the Tagged Address ABI when called from from a
  kernel thread (asynchronous I/O): the kthread does not have the TIF
  flags of the mm owner, so untag the user address unconditionally.

- KVM compute_layout() called before the alternatives code patching.

- Minor clean-ups.
