PATCH 1/1 powerpc/pseries: Disable relocation on exception while going down during crash.

From: Mahesh Salgaonkar <[email protected]>

Disable relocation on exception while going down even in kdump case. This is because we are about clear htab mappings while kexec-ing into kdump kernel and we may run into issues if we still have AIL ON.
