From 3915bcf38fe0b6d130b4bbde97804f29a0becf32 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 22 Mar 2006 00:08:59 -0800 Subject: [PATCH] hugepage: Move hugetlb_free_pgd_range() prototype to hugetlb.h The optional hugepage callback, hugetlb_free_pgd_range() is presently implemented non-trivially only on ia64 (but I plan to add one for powerpc shortly). It has its own prototype for the function in asm-ia64/pgtable.h. However, since the function is called from generic code, it make sense for its prototype to be in the generic hugetlb.h header file, as the protypes other arch callbacks already are (prepare_hugepage_range(), set_huge_pte_at(), etc.). This patch makes it so.
