74ec758daf parisc: Fix itlb miss handler for 64-bit programs
commit 9542130937e9dc707dd7c6b7af73326437da2d50 upstream.

For an itlb miss when executing code above 4 Gb on ILP64 adjust the
iasq/iaoq in the same way isr/ior was adjusted.  This fixes signal
delivery for the 64-bit static test program from
http://ftp.parisc-linux.org/src/64bit.tar.gz.  Note that signals are
handled by the signal trampoline code in the 64-bit VDSO which is mapped
into high userspace memory region above 4GB for 64-bit processes.

2aec5d59c0 parisc/pgtable: Do not drop upper 5 address bits of physical address
commit 166b0110d1ee53290bd11618df6e3991c117495a upstream.

When calculating the pfn for the iitlbt/idtlbt instruction, do not
drop the upper 5 address bits. This doesn't seem to have an effect
on physical hardware which uses less physical address bits, but in
qemu the missing bits are visible.
