From 8f6c99c11ae63ce887686f3e51c412cc4d8d8a7d Mon Sep 17 00:00:00 2001 From: Hugh Dickins Date: Tue, 19 Apr 2005 13:29:17 -0700 Subject: [PATCH] freepgt: remove arch pgd_addr_end ia64 and sparc64 hurriedly had to introduce their own variants of pgd_addr_end, to leapfrog over the holes in their virtual address spaces which the final clear_page_range suddenly presented when converted from pgd_index to pgd_addr_end. But now that free_pgtables respects the vma list, those holes are never presented, and the arch variants can go.
