Merge branch 'for-next/bti-user' into for-next/bti
Merge in user support for Branch Target Identification, which narrowly
missed the cut for 5.7 after a late ABI concern.
* for-next/bti-user:
arm64: bti: Document behaviour for dynamically linked binaries
arm64: elf: Fix allnoconfig kernel build with !ARCH_USE_GNU_PROPERTY
arm64: BTI: Add Kconfig entry for userspace BTI
mm: smaps: Report arm64 guarded pages in smaps
arm64: mm: Display guarded pages in ptdump
KVM: arm64: BTI: Reset BTYPE when skipping emulated instructions
arm64: BTI: Reset BTYPE when skipping emulated instructions
arm64: traps: Shuffle code to eliminate forward declarations
arm64: unify native/compat instruction skipping
arm64: BTI: Decode BYTPE bits when printing PSTATE
arm64: elf: Enable BTI at exec based on ELF program properties
elf: Allow arch to tweak initial mmap prot flags
arm64: Basic Branch Target Identification support
ELF: Add ELF program property parsing support
ELF: UAPI and Kconfig additions for ELF program properties
