ioread8_rep() and its friends.

The generic and IA-64 versions of alloc_zeroed_user_highpage() don't
check the return value from alloc_page_vma().  This can lead to an oops
if we're OOM.

This fixes my oops on PPC64, but I haven't got an IA-64 machine/compiler
handy.

Close a race which could allow for privilege escalation by users with DRI
privileges on Radeon hardware.  Essentially, a malicious program could submit
a packet containing an offset (possibly in main memory) to be rendered from/to,
while a separate thread switched that offset in userspace rapidly between a
valid value and an invalid one.  radeon_check_and_fixup_offset() would pull the
offset in from user space, check it, and spit it back out to user space to be
copied in later by the emit code.  It would sometimes catch the bad value, but
sometimes the malicious program could modify it after the check and get an
invalid offset rendered from/to.

Fix this by allocating a temporary buffer and copying the data in at once.
While here, make the cliprects stuff not do the VERIFYAREA_READ and
COPY_FROM_USER_UNCHECKED gymnastics, avoiding a lock order reversal on FreeBSD.
Performance impact is negligible  -- no difference on r200 to ~1% improvement on
rv200 in quake3 tests (P4 1Ghz, demofour at 1024x768, n=4 or 5)

The attached patch adds documentation for the behaviour of the no-MMU mmap.
Signed-Off-By: David Howells <dhowells@redhat.com>
Signed-Off-By: Linus Torvalds <torvalds@osdl.org>

The attached patch does two things:

 (1) We no longer check the return value of file->f_op->get_unmapped_area()
     unless we actually called it. We know addr is zero otherwise because
     we'd've given an error earlier if it wasn't.

 (2) If -ENOSYS was returned by that operation, then we assume we actually
     called a driver (such as the framebuffer driver) that might want to
     invoke the operation in a lower level driver (such as matroxfb) if one
     exists, and that it found that one didn't.

     We translate the -ENOSYS error into -ENODEV - the error we would have
     given if the operation was not supplied in the file ops.

     Doing this permits us an opportunity for arch_get_unmapped_area() or
     something else to be called if we want that to happen, particularly in
     the MMU case.

If we detect an overlap, we set a flag and wait for a wakeup.  When requests
are handled, if the flag was set, we perform the wakeup.

Note that the code currently in -mm is badly broken.  With this patch applied,
it passes tests the use O_DIRECT to cause lots of overlapping requests.
