The patch titled
Subject: tracing: replace __get_cpu_var uses with this_cpu_ptr
has been added to the -mm tree. Its filename is
tracing-replace-__get_cpu_var-uses-with-this_cpu_ptr.patch
This patch should soon appear at
http://ozlabs.org/~akpm/mmots/broken-out/tracing-replace-__get_cpu_var-uses-with-this_cpu_ptr.patch
and later at
http://ozlabs.org/~akpm/mmotm/broken-out/tracing-replace-__get_cpu_var-uses-with-this_cpu_ptr.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
