[PATCH gnumach] ast: Implement cause_ast_check() by switching cpus

If the current processor is not the one we want to run an ast on, we can bind the current thread to the processor we want, and force a thread switch to that one, then run the ast_check() on the right cpu. --- i386/i386/ast_check.c | 13 +++-- 1 file changed, 11 insertions(+), 2

[PATCH gnumach] cpu_number: Look up cpu kernel_id via lookup table

This speeds up smp slightly by reducing the cpu_number() complexity to have no branching, just a look up table. It also addresses the problem that CPU_NUMBER was only using raw apic_id as an approximation of the kernel_id. Other improvements were to remove unnecessary checks now that the lookup
