Subject: hw/arm/virt: Put GIC register banks on 64K boundaries
X-Git-Tag: qemu-xen-4.6.0-rc1~479^2~1
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=3078e848faed0d6bf03d1ae789975abab9cb7778;p=qemu-upstream-4.6-testing.git

hw/arm/virt: Put GIC register banks on 64K boundaries

For an AArch64 CPU which supports 64K pages, having the GIC
register banks at 4K offsets is potentially awkward. Move
them out to being at 64K offsets. (This is harmless for
AArch32 CPUs and for AArch64 CPUs with 4K pages, so it is simpler
to use the same offsets everywhere than to try to use 64K offsets
only for AArch64 host CPUs.)
