[PATCH] x86_64: Minor fix to TLB flush IPI
Minor fix to TLB flush IPI
Fix minor harmless bug. When doing a flush IPI we used 0xffffffff as
the
catch all wildcard, which is a valid address in a 64bit process. When
this
page was flushed the IPI handler would do a full flush by mistake
instead of
just flushing the page. Use -1ULL instead.
