Subject: [PATCH v2 0/3] arm64: Convert to ARCH_STACKWALK

This series updates the arm64 stacktrace code to use the newer and much
simpler arch_stack_walk() interface, the main benefit being a single
entry point to the arch code with no need for the arch code to worry
about skipping frames. Along the way I noticed that the reliable
parameter to the arch_stack_walk() callback appears to be redundant
so there's also a patch here removing that from the existing code to
simplify the interface.

This is preparatory work for implementing reliable stack trace for
arm64.

v2: Rebase onto v5.9-rc1.

Mark Brown (3):
  stacktrace: Remove reliable argument from arch_stack_walk() callback
  arm64: stacktrace: Make stack walk callback consistent with generic
    code
  arm64: stacktrace: Convert to ARCH_STACKWALK
