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/SubmitChecklist when testing your code ***
The -mm tree is included into linux-next and is updated
there every 3-4 working days

Subject: kernel/cpu.c: make set_cpu_* static inlines
Almost all callers of the set_cpu_* functions pass an explicit true or
false. Making them static inline thus replaces the function calls with a
simple set_bit/clear_bit, saving some .text.
