Subject: [PATCH v2 00/24] cpu,sched: Mark arch_cpu_idle_dead() __noreturn

v2:
- make arch_call_rest_init() and rest_init() __noreturn
- make objtool 'global_returns' work for weak functions
- rebase on tip/objtool/core with dependencies merged in (mingo)
- add acks

v1.1:
- add __noreturn to all arch_cpu_idle_dead() implementations (mpe)

Josh Poimboeuf (24):
  alpha/cpu: Expose arch_cpu_idle_dead()'s prototype declaration
  alpha/cpu: Make sure arch_cpu_idle_dead() doesn't return
  arm/cpu: Make sure arch_cpu_idle_dead() doesn't return
  arm64/cpu: Mark cpu_die() __noreturn
  csky/cpu: Make sure arch_cpu_idle_dead() doesn't return
  ia64/cpu: Mark play_dead() __noreturn
  loongarch/cpu: Make sure play_dead() doesn't return
  loongarch/cpu: Mark play_dead() __noreturn
  mips/cpu: Expose play_dead()'s prototype definition
  mips/cpu: Make sure play_dead() doesn't return
  mips/cpu: Mark play_dead() __noreturn
  powerpc/cpu: Mark start_secondary_resume() __noreturn
  sh/cpu: Make sure play_dead() doesn't return
  sh/cpu: Mark play_dead() __noreturn
  sh/cpu: Expose arch_cpu_idle_dead()'s prototype definition
  sparc/cpu: Mark cpu_play_dead() __noreturn
  x86/cpu: Make sure play_dead() doesn't return
  x86/cpu: Mark play_dead() __noreturn
  xtensa/cpu: Make sure cpu_die() doesn't return
  xtensa/cpu: Mark cpu_die() __noreturn
  sched/idle: Make sure weak version of arch_cpu_idle_dead() doesn't
    return
  objtool: Include weak functions in 'global_noreturns' check
  init: Make arch_call_rest_init() and rest_init() __noreturn
  sched/idle: Mark arch_cpu_idle_dead() __noreturn
