[PATCH] Make percpu_modcopy a macro
davidm@hpl.hp.com writes:
"I'm working on updating the ia64 tree with local_t etc. One
thing that would really help me: could you make
asm-generic/percpu_modcopy() a macro? The routine depends on
cpu_possible(), but I can't including smp.h in percpu.h since
that would lead to recusive header-file dependencies (and in my
opinion, percpu.h should be more "primitive" than smp.h, so that
it can be included virtually everywhere)."
