Subject: MIPS: Fix GCC-4.6 'set but not used' warning in arch/mips/mm/init.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d3ce0e98b7fe17bb1dec9f6d7c50213db01e7189;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

MIPS: Fix GCC-4.6 'set but not used' warning in arch/mips/mm/init.c

Under some combinations of CONFIG_*, lastpfn in page_is_ram is 'set
but not used'.  Mark it as __maybe_unused to quiet the warning/error.
