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.

0d1fa1311b parisc: Prevent booting 64-bit kernels on PA1.x machines
commit a406b8b424fa01f244c1aab02ba186258448c36b upstream.

Bail out early with error message when trying to boot a 64-bit kernel on
32-bit machines. This fixes the previous commit to include the check for
true 64-bit kernels as well.
