| H A D | tlbflush.h | 4c1ba392 Sat Feb 20 17:17:05 CST 2021 Nadav Amit <namit@vmware.com> x86/mm/tlb: Unify flush_tlb_func_local() and flush_tlb_func_remote()
The unification of these two functions allows to use them in the updated
SMP infrastrucutre.
To do so, remove the reason argument from flush_tlb_func_local(), add
a member to struct tlb_flush_info that says which CPU initiated the
flush and act accordingly. Optimize the size of flush_tlb_info while we
are at it.
Unfortunately, this prevents us from using a constant tlb_flush_info for
arch_tlbbatch_flush(), but in a later stage we may be able to inline
tlb_flush_info into the IPI data, so it should not have an impact
eventually.
