    Subject[ 05/94] PARISC: fix PA1.1 oops on boot
    3.3-stable review patch.  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.

    * OK, it is in the temp alias region, check whether "from" or "to".
