If anyone has any objections, please let me know. ------------------ From: James Bottomley commit 5e185581d7c46ddd33cd9c01106d1fc86efb9376 upstream. All PA1.1 systems have been oopsing on boot since commit f311847c2fcebd81912e2f0caf8a461dec28db41 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.
