Christophe LeroyandGreg Kroah-Hartman d8a3693c58 powerpc/32: Fix unpaired stwcx. on interrupt exit ...

[ Upstream commit 10e1c77c36 ]

Commit b96bae3ae2 ("powerpc/32: Replace ASM exception exit by C
exception exit from ppc64") erroneouly copied to powerpc/32 the logic
from powerpc/64 based on feature CPU_FTR_STCX_CHECKS_ADDRESS which is
always 0 on powerpc/32.

Re-instate the logic implemented by commit b64f87c16f ("[POWERPC]
Avoid unpaired stwcx. on some processors") which is based on
CPU_FTR_NEED_PAIRED_STWCX feature.

Fixes: b96bae3ae2 ("powerpc/32: Replace ASM exception exit by C exception exit from ppc64")
