[PATCH] percpu: cleanup PER_CPU_DEF_ATTRIBUTES macro

[Alexander Pateenok]

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.
