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

    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.
