sh: add EXPORT_SYMBOL(min_low_pfn) and EXPORT_SYMBOL(max_low_pfn) to sh_ksyms_32.c
commit ad70b029d2c678386384bd72c7fa2705c449b518 upstream.
Min_low_pfn and max_low_pfn were used in pfn_valid macro if defined
CONFIG_FLATMEM. When the functions that use the pfn_valid is used in
driver module, max_low_pfn and min_low_pfn is to undefined, and fail to
build.
ERROR: "min_low_pfn" [drivers/block/aoe/aoe.ko] undefined!
ERROR: "max_low_pfn" [drivers/block/aoe/aoe.ko] undefined!
make[2]: *** [__modpost] Error 1
make[1]: *** [modules] Error 2
This patch fix this problem.
