Modified Files:
src/sys/arch/x86/include: intr.h
Log Message:
Allow x86 builds to have the opportunity to not have pre-emption
enabled by default. This can be effected by having a:
"options NO_PREEMPTION"
line in the kernel configuration file.
While it was tempting to tie __HAVE_PREEMPTION to MULTIPROCESSOR,
as is currently assumed in sys/kern/kern_stub.c ,
having MULTIPROCESSOR without __HAVE_PREEMPTION
and not having either are valid configuration options which users
could have choice of. We thus err on the side of configurability.
