From 08964c565b2fe49e338ffbe4907adcc19647ef16 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sat, 3 Sep 2005 15:57:41 -0700 Subject: [PATCH] uml: merge duplicated page table code There is a lot of code which is duplicated between the 2 and 3 level implementation, with the only difference that the 3-level implementation is a bit more generalized (instead of accessing directly pte_t.pte, it uses the appropriate access macros). So this code is joined together. As obvious, a "core code nice cleanup" is not a "stability-friendly patch" so usual care applies.
