To: linuxppc-dev , Benjamin Herrenschmidt From: Mahesh J Salgaonkar Date: Fri, 31 Jan 2014 00:30:45 +0530 Message-ID: <20140130190044.19305.63111.stgit@mars> MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Cc: Steve Best , Paul Mackerras , Anton Blanchard , Hari Bathini List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , From: Mahesh Salgaonkar 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.
