almost, highstart_pfn is used in a few printks

arch/i386/mm/discontig.c: In function 'setup_memory':
arch/i386/mm/discontig.c:314: error: 'highstart_pfn' undeclared (first
use in this function)
arch/i386/mm/discontig.c:314: error: (Each undeclared identifier is
reported only once
arch/i386/mm/discontig.c:314: error: for each function it appears in.)
