Subject[PATCH] Revert "MIPS: Fix PAGE_MASK definition"
Message-ID<qTNH3-7bM-1@gated-at.bofh.it>
This reverts commit 22b14523994588279ae9c5ccfe64073c1e5b3c00.

It was originally sent in an earlier revision of the pfn_t patchset.
Besides being broken, the warning is also fixed by PFN_FLAGS_MASK
casting the PAGE_MASK to an unsigned long.
