From 74ae998772041b62e9ad420d602e4f7dbb182cd6 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sun, 5 Mar 2006 18:26:24 -0800 Subject: [SPARC64]: Simplify TSB insert checks. Don't try to avoid putting non-base page sized entries into the user TSB. It actually costs us more to check this than it helps. Eventually we'll have a multiple TSB scheme for user processes. Once a process starts using larger pages, we'll allocate and use such a TSB. Signed-off-by: David S.
