From c4bce90ea2069e5a87beac806de3090ab32128d5 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sat, 11 Feb 2006 21:57:54 -0800 Subject: [SPARC64]: Deal with PTE layout differences in SUN4V. Yes, you heard it right, they changed the PTE layout for SUN4V. Ho hum... This is the simple and inefficient way to support this. It'll get optimized, don't worry. Signed-off-by: David S.
