Here is another fix for a sparse-detected bug: turns out
ptrace_getregs() and ptrace_putregs() did unchecked user-memory
accesses!  These were tricky to see, so it's not surprising that they
went unnoticed so far.  Fortunately, sparse can detect these
trivially.  Patch below should fix the problem, but it's completely
untested (I don't have any testcases for getregs/putregs).

These were found by sparse.

the pfm_fasync() function must not lock the context and mask interrupts
because the fasync_helper() function may allocate memory and this could
lead to sleeping, due to SLAB_KERNEL memory type, if no memory is available.
Going to sleep with interrupts mask is not allowed otherwise you have a deadlock.
The locking of the context is not necessary in this function because it is protected
by caller via get_fd()/put_fd(). The async_queue is also protected. Serialization to
pfm_fasync() is also ensured by caller. The fix is to drop the PROTECT_CTX()
and UNPROTECT_CTX() calls.

Patch in replacement of 2099/1 due to formatting problems.

Some compilers seem to get "%?" wrong in macros.

We really need to check that we have access to the whole of the
signal frame when we allocate it, rather than "most of it" when
we have iWMMXt extensions selected.

- Use ISA_DMA_THRESHOLD as the mask for GFP_DMA allocations.
- Don't allow DMA allocations which are for a "smaller" mask than
  ISA_DMA_THRESHOLD.
- Ensure that "handle" is initialised to our error value when
  returning an error.

Add locking for use of kecardd services.
Use wait_event_interruptible() rather htan interruptible_sleep_on().

Ulrich Drepper points out that EPOLL_CTL_DEL doesn't need to copy any of
the hash events.

Also, we should specify in the man pages that a NULL is allowed in
EPOLL_CTL_DEL.  Currently it does not say that. 

Also, starting from when epoll uses rbtrees instead of hashes, the
'size' hint passed to epoll_create(2) is no more used.  But since an API
change has clearly to be excluded, I guess it'll stay as is.
