crash backtrace

A regression was introduced into Mesa that causes 3DMark2000 to crash in the
high detail helicopter benchmark. A bisect revealed this patch:

68a097596efdf314ec60487a1761cac789ae2367 is the first bad commit
commit 68a097596efdf314ec60487a1761cac789ae2367
Author: Brian Paul <brianp at vmware.com>
Date:   Thu Jan 24 14:44:09 2013 -0700

    util: add some defensive coding in u_upload_alloc()

The terminal output when the crash occurs is this:

radeon: mmap failed, errno: 12
radeon: mmap failed, errno: 12
wine: Unhandled page fault on read access to 0x00000034 at address 0x7cdd1e9b
(thread 001f), starting debugger...

A backtrace of the crash is attached. I do not know where exactly the "mmap
failed" lines are written.
