parisc: entry.S: fix space adjustment on interruption for 64-bit userspace
In wide mode, the IASQ contain the upper part of the GVA
during interruption. This needs to be reversed before
the space is used - otherwise it contains parts of IAOQ.
See Page 2-13 "Processing Resources / Interruption Instruction
Address Queues" in the Parisc 2.0 Architecture Manual page 2-13
for an explanation.
The IAOQ/IASQ space_adjust was skipped for other interruptions
than itlb misses. However, the code in handle_interruption()
checks whether iasq[0] contains a valid space. Due to the not
masked out bits this match failed and the process was killed.
Also add space_adjust for IAOQ1/IASQ1 so ptregs contains sane values.
