Subject: [PATCH] elfcore.h : Fix UML build breakage
Date: Tue, 7 Jul 2009 22:41:50 -0400 (EDT) [thread overview]
Message-ID: <alpine.DEB.2.00.0907072226140.24195@parag-desktop> (raw)
[-- Attachment #1: Type: TEXT/PLAIN, Size: 887 bytes --]
Commit a65e7bfcd74e4c0939f235d2bf9f48ddb3a57991 breaks UML build with
below error -
In file included from fs/proc/kcore.c:17:
include/linux/elfcore.h: In function ‘elf_core_copy_task_regs’:
include/linux/elfcore.h:129: error: implicit declaration of function
‘task_pt_regs’
Fix this by restoring the previous behavior of returning 0 for all arches
like UML that don't define task_pt_regs.
