Florian Fainelli (3):
mm: Silence vmap() allocation failures based on caller gfp_flags
ARM: Silence first allocation with CONFIG_ARM_MODULE_PLTS=y
arm64: Silence first allocation with CONFIG_ARM64_MODULE_PLTS=y

Kristina Martsenko (4):
arm64: traps: fix userspace cache maintenance emulation on a tagged pointer
arm64: hw_breakpoint: fix watchpoint matching for tagged pointers
arm64: entry: improve data abort handling of tagged pointers
arm64: documentation: document tagged pointer stack constraints

Mark Rutland (6):
arm64: xchg: hazard against entire exchange variable
arm64: ensure extension of smp_store_release value
