[PATCH] Add external declaration of pagetable_init() to pgalloc.h

[Atsushi Nemoto <anemo@xxxxxxxxxxxxx>]

This fixes some sparse warnings.

pgtable-32.c:15:6: warning: symbol 'pgd_init' was not declared. Should it be static?
pgtable-32.c:32:13: warning: symbol 'pagetable_init' was not declared. Should it be static?
