Subject: [patch 7/9] x86: thread_info: Merget TIF_ flags.
Date: Mon, 28 Apr 2008 18:52:38 -0700 [thread overview]
Message-ID: <20080429015301.902656145@sgi.com> (raw)
In-Reply-To: 20080429015231.908196699@sgi.com
[-- Attachment #1: merge_tif_flags --]
[-- Type: text/plain, Size: 8318 bytes --]
Both TIF lists are essentially the same. x86_32 also has TIF_SYSCALL_EMU which
must be undefined for the 64 bit case.
