Subject: xen/arm: gic-{v2, hip04}: Use SZ_64K rather than our custom value
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=6e591025594d831c7c9526d1bbdd4ad20b7e99af;p=people%2Fliuw%2Flibxenctrl-split%2Fxen.git

xen/arm: gic-{v2, hip04}: Use SZ_64K rather than our custom value

It's not easy to understand PAGE_SIZE * 0x10 and PAGE_SIZE * 16 at the
first glance.
