[PARISC] fix TLB fault path on PA2.0 narrow systems
commit 5e185581d7c46ddd33cd9c01106d1fc86efb9376
Author: James Bottomley <JBottomley@Parallels.com>
[PARISC] fix PA1.1 oops on boot
Didn't quite fix the crash on boot. It moved it from PA1.1 processors to
PA2.0 narrow kernels. The final fix is to make sure the [id]tlb_miss_20 paths
also work. Even on narrow systems, these paths require using the wide
instructions becuase the tlb insertion format is wide. Fix this by
conditioning the dep[wd],z on whether we're being called from _11 or _20[w]
paths.
