From cbb921443424fb8019e52bae83e442d01f7715ef Mon Sep 17 00:00:00 2001 From: Russ Anderson Date: Fri, 4 Nov 2005 16:58:28 -0600 Subject: [PATCH] [IA64] MCA recovery: Bump reference count on bad pages When a page has a memory uncorrectable ECC error, the recovery code wants to prevent the page from being reused. This change bumps the reference count to prevent the page from getting back on the free list.
