Subject: [IA64] A small fix in mm.c. Use PAGE_MASK, not ~PAGE_MASK.
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~14107
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=45ac7f53d72d2205089e351068b21e2ecbcf0c25;p=xen.git

[IA64] A small fix in mm.c. Use PAGE_MASK, not ~PAGE_MASK.

~PAGE_MASK was wrongly used to get page aligned address.
Use PAGE_MASK, not ~PAGE_MASK.
