Subject[GIT PULL] arm64 fixes for 5.5-rc1
Hi Linus,

Please pull the arm64 fixes below. Thanks.

The following changes since commit d8e85e144bbe12e8d82c6b05d690a34da62cc991:

arm64: Kconfig: add a choice for endianness (2019-11-14 14:39:03 +0000)

are available in the Git repository at:

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.
