I get the following compile error:
[tmolina@lap linux-2.5-tm]$ make bzImage > makeimage
arch/i386/kernel/apm.c:336:1: warning: "savesegment" redefined

include/asm/elf.h:63:1: warning: this is the location of the previous definition
in apm.c it is:
#define savesegment(seg, where) \
__asm__ __volatile__("movl %%" #seg ",%0" : "=m" (where))
in elf.h
#define savesegment(seg,value) \
asm volatile("movl %%" #seg ",%0":"=m" (*(int *)&(value)))
Is there any reason we can't just do the following:
