Subject: iommu/core: Use PAGE_SIZE instead of hard-coded value
X-Git-Tag: v3.2-rc1~117^2^5~10^4
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=85410340e0d0224c78c7d40a3ac7e1b3e9670cf1;p=linux-2.6-block.git

iommu/core: Use PAGE_SIZE instead of hard-coded value

Replace the hard-coded 4kb by PAGE_SIZE to make iommu-api
implementations possible on architectures where
PAGE_SIZE != 4kb.
