Put back a secondary declaration of ipi_base_addr in hardirq.h.  It
really is needed for UP builds and there doesn't seem to be an easy
way to avoid include-hell otherwise.

We had hardcoded defines for TI_TASK TI_EXEC_DOMAIN, TI_FLAGS, TI_CPU,
TI_ADDR_LIMIT, TI_PRE_COUNT, TI_RESTART_BLOCK; but only two of these
were ever used.  Remove all from thread_info.h, and generate the two
that we do use (TI_FLAGS and TI_PRE_COUNT) in asm_offsets.c

Here are three more sparse-triggered fixes which didn't fit anywhere
else.  The first one gets rid of some quoting in palinfo.c which
sparse doesn't like.  This used to be necessary because GCC would
otherwise warn about an unknown trigraph.  That's not a problem
anymore since the kernel is now being compiled with -Wno-trigraphs.
The efirtc.c patch is mostly sparse-annotations but also cleans up
trailing whitespace.  Finally, the bitfields in rwlock_t are changed
to be explicitly "unsigned" to avoid a warning from sparse (it doesn't
like 1-bit signed bitfields in particular).

This patch adds __iomem annotations.  The only less-than-trivial part
of the patch is the change of ipi_base_addr from "unsigned long" to
"void __iomem *" but even that part should be safe.  The patch results
in additional warnings from certain drivers (e.g., eepro100.c) but the
warnings are harmless and just indicate that the offending drivers
need to be updated for the more strict __iomem checking.  The patch
has been boot-tested.

This enables sparse for ia64 and adds a basic set of __user
annotations.  Apart for sys_execve() and the uaccess.h changes, the
patch is trivially safe.  Also note that in gcc_intrin.h, I
changed "asm __volatile" to "asm volatile" since sparse didn't
like the old version (and it's a "strane" version anyhow).
Patch has been (boot) tested.

Sparse really wants NULL for NULL-pointers.  This patch makes it so.

copy_siginfo_from_user32() directly dereferences a user-pointer, which
is a no-no.  At that point, to->si_code already has been initialized
so I think we can just use to->si_code instead.  Compile-tested (only)
patch attached.

Another sparse-detected bug.

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.
