Subject: [PATCH 2/5] x86: Nuke the supervisor_stack field in i386 thread_info
Date: Thu, 28 Jul 2011 21:42:17 -0400	[thread overview]
Message-ID: <20110729014248.019624959@goodmis.org> (raw)
In-Reply-To: 20110729014215.328710900@goodmis.org

[-- Attachment #1: 0002-x86-Nuke-the-supervisor_stack-field-in-i386-thread_i.patch --]
[-- Type: text/plain, Size: 941 bytes --]

From: Steven Rostedt <srostedt@redhat.com>

Nothing references the supervisor_stack in the thread_info field,
and it does not exist in x86_64. To make the two more the same,
it is being removed.
