With POWER10, single tlbiel instruction invalidates all the congruence
class of the TLB and hence we need to issue only one tlbiel with SET=0.

If the RTAS call to query the PE address for a device fails we jump the
err: label where an error message is printed along with the return code.
However, the printed return code is from the "ret" variable which isn't set
at that point since we assigned the result to "addr" instead. Fix this by
The eeh_pe->config_addr field was supposed to be removed in
commit 35d64734b643 ("powerpc/eeh: Clean up PE addressing") which made it
largely unused. Finish the job.

Unlike PPC64 which had a single head_64.S, PPC32 are multiple ones.
There is the head_32.S, selected by default based on the value of BITS
and overridden based on some CONFIG_ values. This leads to thinking
that it may be selected by different types of PPC32 platform but
indeed it ends up being
head_book3s_32.S is only built when CONFIG_PPC_BOOK3S_32 is selected.
Remove all conditions based on CONFIG_PPC_BOOK3S_32 in the file.
