Subject: [PATCH] ppc32: ide, mpc8xx - volatile fix
Date: Sat, 8 Jan 2005 19:02:09 +0100 (CET) [thread overview]
Message-ID: <20050108180050.14410.66973.89460@kubu> (raw)
This patch makes sure that a PCMCIA register is accessed with a volatile
pointer. Wierd things happen without the patch if compiled with gcc-3.
