Subject: MIPS: mm: Fix highmem compile
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=625cfb6f20360e82a9c65d8184df49f1d67bc18e;p=linux.git

MIPS: mm: Fix highmem compile

Commit a5718fe8f70f ("MIPS: mm: Drop boot_mem_map") removed the
definition of a page variable for some reason, but that variable is
still used. Restore it to fix compilation with CONFIG_HIGHMEM enabled.
