Subject: [PATCH 011/117] fix PA1.1 oops on boot
|
|
|
|
commit 5e185581d7c46ddd33cd9c01106d1fc86efb9376 upstream.

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.
