The patch titled Subject: percpu: remove PER_CPU_DEF_ATTRIBUTES macro has been added to the -mm tree. Its filename is percpu-cleanup-per_cpu_def_attributes-macro.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/percpu-cleanup-per_cpu_def_attributes-macro.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/percpu-cleanup-per_cpu_def_attributes-macro.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Alexander Pateenok <pateenoc@xxxxxxxxx> Subject: 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.
