Subject: [PATCH] powerpc/pseries: Disable relocation on exception while going down during crash.
Date: Fri, 31 Jan 2014 00:30:45 +0530 [thread overview]
Message-ID: <20140130190044.19305.63111.stgit@mars> (raw)
From: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>
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.
