[ARM] 3044/1: Fix sparse warnings about incompatible pointer types for register defined in pxa-regs.h

Patch from Ian Campbell

The sparse warning initially surfaced in sound/arm/pxa2xx-ac97.c
because it was using u32 * variables to hold the unsigned long *
register addresses.

I submitted an ALSA patch for this http://thread.gmane.org/gmane.linux.alsa.devel/27804 issue and it was suggested that it might be preferable to change the register
definitions to use u32.

Most other subarches seem to use u32 for their register type, at least
the ones which use a __REG macro (like the PXA) do. Nico indicated in
the thread above that he wouldn't mind this patch.

Changing the type required fixes for opposite warnings in the pxa2xx usb
gadget code but that was the only new warning introduced on defconfig
or lubbock, mainstone and our own PXA255 boards.

[ARM] 3017/1: Add support for 36-bit addresses to create_mapping()

Patch from Deepak Saxena

This patch adds support for 36-bit static mapped I/O. While there
are no platforms in the tree ATM that use it, it has been tested
tested on the IXP2350 NPU and I would like to get the support for
that chipset upstream one piece at a time. There are also other
Intel chipset ports in development that are waiting on this to go
upstream.

The patch replaces the print formats for physical addresses with
%016llx which will create a bit extraneous output on 32-bit systems,
but I think that is cleaner than having #ifdefs, specially since
users will only see the output in error cases.

[ARM] 4/4 Combine oprofile common and init code

There is nothing special about having the init code separate from

[ARM] 3/4 Rename common oprofile code

The common oprofile code assumes the name "PMU" (from Intel's

start adding oprofile support for other machine types which

pmu_*.

[BLOCK] Reimplement elevator switch

 This patch reimplements elevator switch.  This patch assumes generic
dispatch queue patchset is applied.

 * Each request is tagged with REQ_ELVPRIV flag if it has its elevator
   private data set.
 * Requests which doesn't have REQ_ELVPRIV flag set never enter
   iosched.  They are always directly back inserted to dispatch queue.
   Of course, elevator_put_req_fn is called only for requests which
   have its REQ_ELVPRIV set.
 * Request queue maintains the current number of requests which have
   its elevator data set (elevator_set_req_fn called) in
   q->rq->elvpriv.
 * If a request queue has QUEUE_FLAG_BYPASS set, elevator private data
   is not allocated for new requests.

 To switch to another iosched, we set QUEUE_FLAG_BYPASS and wait until
elvpriv goes to zero; then, we attach the new iosched and clears
QUEUE_FLAG_BYPASS.  New implementation is much simpler and main code
paths are less cluttered, IMHO.

[PATCH] 02/05: update ioscheds to use generic dispatch queue

This patch updates all four ioscheds to use generic dispatch
queue.  There's one behavior change in as-iosched.

* In as-iosched, when force dispatching
  (ELEVATOR_INSERT_BACK), batch_data_dir is reset to REQ_SYNC
  and changed_batch and new_batch are cleared to zero.  This
  prevernts AS from doing incorrect update_write_batch after
  the forced dispatched requests are finished.

* In cfq-iosched, cfqd->rq_in_driver currently counts the
  number of activated (removed) requests to determine
  whether queue-kicking is needed and cfq_max_depth has been
  reached.  With generic dispatch queue, I think counting
  the number of dispatched requests would be more appropriate.

* cfq_max_depth can be lowered to 1 again.
