From 45f16ef46bb22c57464e796de49a318d89950fa3 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Tue, 15 May 2012 11:04:19 +0100 Subject: [PATCH] [PARISC] fix PA1.1 oops on boot All PA1.1 systems have been oopsing on boot since commit b2482eb22c5a728cb6df57fb675a2c6d15ab7a3e Author: James Bottomley Date: Wed Dec 22 10:22:11 2010 -0600 parisc: flush pages through tmpalias space because a PA2.0 instruction was accidentally introduced into the PA1.1 TLB insertion interruption path when it was consolidated with the do_alias macro. Fix the do_alias macro only to use PA2.0 instructions if compiled for 64 bit.
