[Xen-devel] [PATCH 02 of 12] blktap2: add tlb flush properly

[Daniel Stodden <daniel.stodden@xxxxxxxxxx>]

xen_invlpg() flushes tlb on its cpu, but tlb flush is needed on
all cpus. So replace xen_invlpg() with more proper ones.
Maybe it would be possible to make tlb flush less.
this patch also makes blktap2 compile on ia64 because xen_invlpg()
is x86 specific.

 * rebase against git-da22857f (port blktap2 from 2.6.18 to tip)
 * rebase against git-fbbc8527 (wean off of use of the BlkBack pageflag)
 * gpl-export flush_tlb_page, flush_tlb_all
