Subject: [patch 41/44] make thread_info.flags an unsigned long
Date: Wed, 01 Feb 2006 18:03:05 +0900	[thread overview]
Message-ID: <20060201090335.476045000@localhost.localdomain> (raw)
In-Reply-To: 20060201090224.536581000@localhost.localdomain

[-- Attachment #1: thread_info-flags.patch --]
[-- Type: text/plain, Size: 3129 bytes --]

The *_bit() routines are defined to work on a pointer to unsigned long.
And the thread_info.flags is passed to *_bit() routines in
include/linux/thread_info.h. But

 - alpha: flags is unsigned int
 - ia64, sh, x86_64: flags is __u32

So flags should be changed to unsigned long instead.

The only affected 64-platforms are little endian, so it will work
without this change. But it's better to change it before people copy the
code to a big endian platform.
