From b1b901c2029aa0fd8aa4ac5f04f31648ae2358b4 Mon Sep 17 00:00:00 2001 From: Russ Anderson Date: Wed, 6 Apr 2005 00:07:00 -0700 Subject: [IA64] MCA recovery improvements Jack Steiner uncovered some opportunities for improvement in the MCA recovery code. 1) Set bsp to save registers on the kernel stack. 2) Disable interrupts while in the MCA recovery code. 3) Change the way the user process is killed, to avoid a panic in schedule. Testing shows that these changes make the recovery code much more reliable with the 2.6.12 kernel.
