From 2a5eacca85d39d8b6dffae821d7d260f05584dc7 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Thu, 31 Dec 2009 12:19:24 +0000 Subject: sh: Move page table allocation out of line We also switched away from quicklists and instead moved to slab caches. After benchmarking both implementations the difference is negligible. The slab caches suit us better though because the size of a pgd table is just 4 entries when we're using a 3-level page table layout and quicklists always deal with pages.
