Subject: x86: move max_pfn_mapped and max_low_pfn_mapped to setup.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2b72394e4089643f11669d9610907a1442fe044a;p=linux-beck.git

x86: move max_pfn_mapped and max_low_pfn_mapped to setup.c

This patch moves the max_pfn_mapped and max_low_pfn_mapped global
variables to kernel/setup.c where they're initialized.
