Ian Campbell 7edc24c4d1 [ARM] 3032/1: sparse: complains about generic_fls() prototype in asm-arm/bitops.h
Patch from Ian Campbell

Sparse complains about the definition of generic_fls in asm-arm/bitops.h:
  CHECK   /home/icampbell/devel/kernel/2.6/arch/arm/mach-pxa/viper.c
include2/asm/bitops.h:350:34: error: marked inline, but without a definition

The definition is unnecessary since linux/bitops.h defines generic_fls before including asm/bitops.h and asm/bitops.h should not be included directly. There are still some places where asm/bitops.h is directly included, but I think that code should be fixed. I was a little wary of the patch for this reason but lubbock, mainstone and assabet all build OK and so do my in house boards...

ARM is the only arch with the generic_fls prototype in this way.

Patch from Ben Dooks

Avoid the possiblity that if the board is using
a 16.9334 or higher crystal with a high PLL
multiplier, then the pll value could overflow
the capability of an int.

Also fix the value types of the intermediate
variables to unsigned int.

The following trivial patch is to fix what looks like a typo in the PXA register

Kenneth Tan 251b928cdf [ARM] 3021/1: Interrupt 0 bug fix for ixp4xx
Patch from Kenneth Tan

The get_irqnr_and_base subroutine of ixp4xx does not take interrupt 0 condition into account properly. We should not perform "subs" here. The Z flag will be set when interrupt 0 occur, which resulting "movne r1, sp" in the caller routine (irq_handler) not being executed.

When interrupt 0 occur:
o if CONFIG_CPU_IXP46X is not set, "subs" will set the Z flag and return
o if CONFIG_CPU_IXP46X is set, codes in upper interrupt handling will be trigerred. But since this is not supper interrupt, the "cmp" in the upper interrupt handling portion will set the Z flag and return

Lennert Buytenhek 917afce100 [ARM] 2911/1: ixp2000_reg_{read,write} accessors
Patch from Lennert Buytenhek

This patch:
- changes the ixp2000_reg_write accessor to take a 'volatile void *'
  instead of a 'volatile unsigned long *', which then allows passing in
  a u32 * as first argument without being greeted with a warning; and
- adds an ixp2000_reg_read accessor.
We can then use these accessors in ixp2000 code to access on-chip
peripherals, instead of directly dereferencing pointers.  This is for
use by the ixp2000 microengine driver which was recently announced on
netdev.  We can't use readl/writel on the ixp2000 since it is usually
run in big-endian mode, and on big-endian platforms, readl/writel
perform byteswapping.
A future patch will remove the readback from ixp2000_reg_write, since
it's not needed to prevent erratum #66, and add manual readbacks to the
places that need them (writes are not synchronous since we map in device
space using XCB=101 nowadays), such as interrupt disabling and GPIO
manipulation.  See also:

Richard Purdie 50a5de4482 [PATCH] SharpSL: Abstract c7x0 specifics from Corgi SSP
Sharp's newer range of Zaurus clamshell handhelds, the cxx00's are similar to
the c7x0 series yet different.  This patch series abstracts the differences
and generates a set of common drivers that support both series of devices.  It
then adds machine support for Spitz (SL-C3000) and Borzoi (SL-C3100).  Hooks
for Akita (SL-C1000) differences are also added.  The I2C driver for its IO
expander is the only missing piece.

This patch:

Separate out the Sharp Zaurus c7x0 series specific code from corgi_ssp.c so
that other models such as the cxx00's can share it.  Create sharpsl.h which
will be used to abstract machine/model specifics.

This enables the driver to be used by the Zaurus cxx00 series.

Ingo Molnar fb1c8f93d8 [PATCH] spinlock consolidation
This patch (written by me and also containing many suggestions of Arjan van
de Ven) does a major cleanup of the spinlock code.  It does the following
things:

 - consolidates and enhances the spinlock/rwlock debugging code

 - simplifies the asm/spinlock.h files

 - encapsulates the raw spinlock type and moves generic spinlock
   features (such as ->break_lock) into the generic code.

 - cleans up the spinlock code hierarchy to get rid of the spaghetti.

Most notably there's now only a single variant of the debugging code,
located in lib/spinlock_debug.c.  (previously we had one SMP debugging
variant per architecture, plus a separate generic one for UP builds)

Also, i've enhanced the rwlock debugging facility, it will now track
write-owners.  There is new spinlock-owner/CPU-tracking on SMP builds too.
All locks have lockup detection now, which will work for both soft and hard
spin/rwlock lockups.

The arch-level include files now only contain the minimally necessary
subset of the spinlock code - all the rest that can be generalized now
lives in the generic headers:

 include/asm-i386/spinlock_types.h       |   16
 include/asm-x86_64/spinlock_types.h     |   16

I have also split up the various spinlock variants into separate files,
making it easier to see which does what. The new layout is:

   SMP                         |  UP
   ----------------------------|-----------------------------------
   asm/spinlock_types_smp.h    |  linux/spinlock_types_up.h
   linux/spinlock_types.h      |  linux/spinlock_types.h
   asm/spinlock_smp.h          |  linux/spinlock_up.h
   linux/spinlock_api_smp.h    |  linux/spinlock_api_up.h
   linux/spinlock.h            |  linux/spinlock.h

/*
 * here's the role of the various spinlock/rwlock related include files:
 *
 * on SMP builds:
 *
 *  asm/spinlock_types.h: contains the raw_spinlock_t/raw_rwlock_t and the
 *                        initializers
 *
 *  linux/spinlock_types.h:
 *                        defines the generic type and initializers
 *
 *  asm/spinlock.h:       contains the __raw_spin_*()/etc. lowlevel
 *                        implementations, mostly inline assembly code
 *
 *   (also included on UP-debug builds:)
 *
 *  linux/spinlock_api_smp.h:
 *                        contains the prototypes for the _spin_*() APIs.
 *
 *  linux/spinlock.h:     builds the final spin_*() APIs.
 *
 * on UP builds:
 *
 *  linux/spinlock_type_up.h:
 *                        contains the generic, simplified UP spinlock type.
 *                        (which is an empty structure on non-debug builds)
 *
 *  linux/spinlock_types.h:
 *                        defines the generic type and initializers
 *
 *  linux/spinlock_up.h:
 *                        contains the __raw_spin_*()/etc. version of UP
 *                        builds. (which are NOPs on non-debug, non-preempt

crosscompilers.  m32r, mips, sh, sparc, have not been tested yet, but should
be mostly fine.

From: Grant Grundler <grundler@parisc-linux.org>

  Booted and lightly tested on a500-44 (64-bit, SMP kernel, dual CPU).
  Builds 32-bit SMP kernel (not booted or tested).  I did not try to build
  non-SMP kernels.  That should be trivial to fix up later if necessary.

  I converted bit ops atomic_hash lock to raw_spinlock_t.  Doing so avoids
  some ugly nesting of linux/*.h and asm/*.h files.  Those particular locks
  are well tested and contained entirely inside arch specific code.  I do NOT
  expect any new issues to arise with them.

 If someone does ever need to use debug/metrics with them, then they will
  need to unravel this hairball between spinlocks, atomic ops, and bit ops
  that exist only because parisc has exactly one atomic instruction: LDCW
  (load and clear word).

Arnaud Patard 20fd576768 [PATCH] s3c2410fb: ARM S3C2410 framebuffer driver
This set of two patches add support for the framebuffer of the Samsung S3C2410
ARM SoC.  This driver was started about one year ago and is now used on iPAQ
h1930/h1940, Acer n30 and probably other s3c2410-based machines I'm not aware
of.  I've also heard yesterday that it's working also on iPAQ rx3715/rx3115
(s3c2440-based machines).

Nicolas Pitre 61c8c158c8 [ARM] 2892/1: remove gcc workaround for direct access to absolute memory addresses
Patch from Nicolas Pitre

It used to make a difference in the gcc-2.95 era.  However these days
modern gcc apparently got better at not being influenced by such constructs
(which is good in general) and therefore such workaround is of no real
advantage anymore.
The good news is that gcc (from version 4.1.0) is now fixed with
regards to the defficiency this workaround was trying to address.
For those interested the patch can easily be backported to older gcc
versions and can be found here:
http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/gcc/config/arm/arm.c.diff?r1=1.476&r2=1.478
and also here:

David S. Miller 085ae41f66 [PATCH] Make sparc64 use setup-res.c
There were three changes necessary in order to allow
sparc64 to use setup-res.c:

1) Sparc64 roots the PCI I/O and MEM address space using
   parent resources contained in the PCI controller structure.
   I'm actually surprised no other platforms do this, especially
   ones like Alpha and PPC{,64}.  These resources get linked into the
   iomem/ioport tree when PCI controllers are probed.

   So the hierarchy looks like this:

   iomem --|
	   PCI controller 1 MEM space --|
				        device 1
					device 2
					etc.
	   PCI controller 2 MEM space --|
				        ...
   ioport --|
            PCI controller 1 IO space --|
					...
            PCI controller 2 IO space --|
					...

   You get the idea.  The drivers/pci/setup-res.c code allocates
   using plain iomem_space and ioport_space as the root, so that
   wouldn't work with the above setup.

   So I added a pcibios_select_root() that is used to handle this.
   It uses the PCI controller struct's io_space and mem_space on
   sparc64, and io{port,mem}_resource on every other platform to
   keep current behavior.

2) quirk_io_region() is buggy.  It takes in raw BUS view addresses
   and tries to use them as a PCI resource.

   pci_claim_resource() expects the resource to be fully formed when
   it gets called.  The sparc64 implementation would do the translation
   but that's absolutely wrong, because if the same resource gets
   released then re-claimed we'll adjust things twice.

   So I fixed up quirk_io_region() to do the proper pcibios_bus_to_resource()
   conversion before passing it on to pci_claim_resource().

3) I was mistakedly __init'ing the function methods the PCI controller
   drivers provide on sparc64 to implement some parts of these
   routines.  This was, of course, easy to fix.

So we end up with the following, and that nasty SPARC64 makefile
ifdef in drivers/pci/Makefile is finally zapped.
