3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: James Bottomley <redacted>

commit 5e185581d7c46ddd33cd9c01106d1fc86efb9376 upstream.

All PA1.1 systems have been oopsing on boot since

commit f311847c2fcebd81912e2f0caf8a461dec28db41
Author: James Bottomley [off-list ref]
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.
