Linus Torvalds e77fafe9af arm64 updates for 5.4:
- 52-bit virtual addressing in the kernel
 
 - New ABI to allow tagged user pointers to be dereferenced by syscalls
 
 - Early RNG seeding by the bootloader
 
 - Improve robustness of SMP boot
 
 - Fix TLB invalidation in light of recent architectural clarifications
 
 - Support for i.MX8 DDR PMU
 
 - Remove direct LSE instruction patching in favour of static keys
 
 - Function error injection using kprobes
 
 - Support for the PPTT "thread" flag introduced by ACPI 6.3
 
 - Move PSCI idle code into proper cpuidle driver
 
 - Relaxation of implicit I/O memory barriers
 
 - Build with RELR relocations when toolchain supports them
 
 - Numerous cleanups and non-critical fixes

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

Pull arm64 updates from Will Deacon:
 "Although there isn't tonnes of code in terms of line count, there are
  a fair few headline features which I've noted both in the tag and also
  in the merge commits when I pulled everything together.

  The part I'm most pleased with is that we had 35 contributors this
  time around, which feels like a big jump from the usual small group of
  core arm64 arch developers. Hopefully they all enjoyed it so much that
  they'll continue to contribute, but we'll see.

  It's probably worth highlighting that we've pulled in a branch from
  the risc-v folks which moves our CPU topology code out to where it can
  be shared with others.

  Summary:

   - 52-bit virtual addressing in the kernel

   - New ABI to allow tagged user pointers to be dereferenced by
     syscalls

   - Early RNG seeding by the bootloader

   - Improve robustness of SMP boot

   - Fix TLB invalidation in light of recent architectural
     clarifications

   - Support for i.MX8 DDR PMU

   - Remove direct LSE instruction patching in favour of static keys

   - Function error injection using kprobes

   - Support for the PPTT "thread" flag introduced by ACPI 6.3

   - Move PSCI idle code into proper cpuidle driver

   - Relaxation of implicit I/O memory barriers

   - Build with RELR relocations when toolchain supports them

   - Numerous cleanups and non-critical fixes"
