Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux

Pull arm64 festive updates from Will Deacon:
"In the end, we ended up with quite a lot more than I expected:

- Support for ARMv8.3 Pointer Authentication in userspace (CRIU and
kernel-side support to come later)

- Support for per-thread stack canaries, pending an update to GCC
that is currently undergoing review

- Support for kexec_file_load(), which permits secure boot of a kexec
payload but also happens to improve the performance of kexec
dramatically because we can avoid the sucky purgatory code from
userspace. Kdump will come later (requires updates to libfdt).

- Optimisation of our dynamic CPU feature framework, so that all
detected features are enabled via a single stop_machine()
invocation

- KPTI whitelisting of Cortex-A CPUs unaffected by Meltdown, so that
they can benefit from global TLB entries when KASLR is not in use

- 52-bit virtual addressing for userspace (kernel remains 48-bit)

- Patch in LSE atomics for per-cpu atomic operations

- Custom preempt.h implementation to avoid unconditional calls to
preempt_schedule() from preempt_enable()

- Support for the new 'SB' Speculation Barrier instruction

- Vectorised implementation of XOR checksumming and CRC32
optimisations

- Workaround for Cortex-A76 erratum #1165522

- Improved compatibility with Clang/LLD

- Support for TX2 system PMUS for profiling the L3 cache and DMC

- Reflect read-only permissions in the linear map by default

- Ensure MMIO reads are ordered with subsequent calls to Xdelay()

- Initial support for memory hotplug

- Tweak the threshold when we invalidate the TLB by-ASID, so that
mremap() performance is improved for ranges spanning multiple PMDs.

- Minor refactoring and cleanups"

arm64/neon: add workaround for ambiguous C99 stdint.h types

In a way similar to ARM commit 09096f6a0ee2 ("ARM: 7822/1: add workaround
for ambiguous C99 stdint.h types"), this patch redefines the macros that
are used in stdint.h so its definitions of uint64_t and int64_t are
compatible with those of the kernel.
