[PATCH] make used_math SMP-safe
Convert the unsafe signed (16bit) used_math to a safe and optimal
PF_USED_MATH
I might have broken arm, see the very first change in the patch to
asm-offsets.c, rest looks ok at first glance.
If you want used_math to return 0 or 1 (instead of 0 or PF_USED_MATH), just
s/!!// in the below patch and place !! in sched.h::*used_math()
accordingly after applying the patch, it should work just fine. Using !!
only when necessary as the below is optimal.
From: Yoichi Yuasa <yuasa@hh.iij4u.or.jp>
This patch had fixed restore_sigcontext/restore_sigcontext32 about MIPS.
