x86: prepare for tlb merge
Impact: clean up, ipi vector number reordering for x86_32 Make the following changes to prepare for tlb merge. * reorder x86_32 ip vectors * adjust tlb_32.c and tlb_64.c such that their logics coincide exactly - on spurious invalidate ipi, tlb_32 acks the irq - tlb_64 now has proper memory barriers around clearing flush_cpumask (no change in generated code) * unexport flush_tlb_page from tlb_32.c, there's no user * use unsigned int for cpu id * drop unnecessary includes from tlb_64.c Signed-off-by: Tejun Heo <tj@kernel.org>

* some of the following vectors are 'rare', they are merged
* into a single vector (CALL_FUNCTION_VECTOR) to save vector space.
* TLB, reschedule and local APIC vectors are performance-critical.
