[PATCH] x86: convert highmem macros to functions

[Marcin Slusarz <marcin.slusarz@gmail.com>]

convert kmap_init, permanent_kmaps_init, set_highmem_pages_init macros
defined when !CONFIG_HIGHMEM to functions

supresses following warning from gcc:
arch/x86/mm/init_32.c: In function 'pagetable_init':
arch/x86/mm/init_32.c:516: warning: unused variable 'pgd_base'
