Subject: percpu: remove PER_CPU_DEF_ATTRIBUTES macro
X-Git-Tag: v4.20-rc1~52^2~39
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=69a60bc75fe73511af89328ded1b33bc4a625a5c;p=linux.git

percpu: remove PER_CPU_DEF_ATTRIBUTES macro

The macro is not used:

  $ grep -r PER_CPU_DEF_ATTRIBUTES
  include/linux/percpu-defs.h:	__PCPU_ATTRS(sec) PER_CPU_DEF_ATTRIBUTES __weak		\
  include/linux/percpu-defs.h:	__PCPU_ATTRS(sec) PER_CPU_DEF_ATTRIBUTES		\
  include/asm-generic/percpu.h:#ifndef PER_CPU_DEF_ATTRIBUTES
  include/asm-generic/percpu.h:#define PER_CPU_DEF_ATTRIBUTES

It was added with b01e8dc34379 ("alpha: fix percpu build breakage") and
removed in 2009 with b01e8dc34379..6088464cf1ae.
