b216c01829 [ARM] 3098/1: pxa2xx disable ssp irq
Patch from Liam Girdwood

This patch allows users of the pxa SSP driver to register their own irq
handlers instead of using the default SSP handler. It also cleans up the
CKEN clock and irq detection as the values are now stored in a table.

This patch replaces 2845/1

Changes:-
o Added flags parameter to ssp_init()
o Added SSP_NO_IRQ flag to disable registering of ssp irq handler (for
drivers that want to register their own handler)
o Cleaned up clock and irq detection, values are now stored in table.
o Added build changes to allow other drivers (e.g audio) to select the
ssp driver.
o corgi_ssp.c changed to use new interface.

078abcf95c [ARM] 3096/1: Add SharpSL Zaurus power and battery management core driver
Patch from Richard Purdie

This patch adds a power and battery management core driver which with
the addition of the right device files, supports the c7x0 and cxx00
series of Sharp Zaurus handhelds.

The driver is complex for several reasons. Battery charging is manually
monitored and controlled. When suspended, the device needs to
periodically partially resume, check the charging status and then
re-suspend. It does without bothering the higher linux layers as
a full resume and re-suspend is unnecessary. The code is carefully
written to avoid interrupts or calling code outside the module under
these circumstances. It also vets the various wake up sources and
monitors the device's power situation.

Hooks to limit the backlight intensity and to notify the battery
monitoring code of backlight events are connected/added as the
backlight is one of the biggest users of power on the device.

a7918f39bb [ARM] 3140/1: NSLU2 machine support
Patch from Alessandro Zummo

This patch adds support for the LinkSys NSLU2 running with
both big and little-endian kernels. The LinkSys NSLU2 is
a cost engineered ARM, XScale 420 based system similar to
the the Intel IXDP425 evaluation board. It uses the
IXP4XX ARCH.

While this patch applies independently of other patches
the resultant kernel requires further patches to successfully
use onboard devices, including the onboard flash. Since these
patches are independent of this one they will be submitted
separately.

A defconfig is not included here because not all of
the required drivers are actually in the kernel.
We intend to provide one as soon as the patches
will be incorporated in mainstream.

This patch is the combined work of nslu2-linux.org

0f34f49029 [PATCH] ppc64: fix PCI IO mapping
phbs_remap_io(), which maps the PCI IO space into the kernel virtual space,
is called too early on powermac, and thus doesn't work.

This fixes it by removing the call from all platforms and putting it back
into the ppc64 common code where it belongs, after the actual probing of
the bus.

That means that before that call, only the ISA IO space (if any) is mapped,
any PIO access (from quirks for example) will fail. This happens not to be
a problem for now, but we'll have to rework that code if it becomes one in
the future.

3ddfbcf19b [PATCH] powerpc: Consolidate asm compatibility macros
This patch consolidates macros used to generate assembly for
compatibility across different CPUs or configs.  A new header,
asm-powerpc/asm-compat.h contains the main compatibility macros.  It
uses some preprocessor magic to make the macros suitable both for use
in .S files, and in inline asm in .c files.  Headers (bitops.h,
uaccess.h, atomic.h, bug.h) which had their own such compatibility
macros are changed to use asm-compat.h.

ppc_asm.h is now for use in .S files *only*, and a #error enforces
that.  As such, we're a lot more careless about namespace pollution
here than in asm-compat.h.

While we're at it, this patch adds a call to the PPC405_ERR77 macro in
futex.h which should have had it already, but didn't.

26ef5c0957 [PATCH] powerpc: Merge cacheflush.h and cache.h
The ppc32 and ppc64 versions of cacheflush.h were almost identical.
The two versions of cache.h are fairly similar, except for a bunch of
register definitions in the ppc32 version which probably belong better
elsewhere.  This patch, therefore, merges both headers.  Notable
points:
	- there are several functions in cacheflush.h which exist only
on ppc32 or only on ppc64.  These are handled by #ifdef for now, but
these should probably be consolidated, along with the actual code
behind them later.
	- Confusingly, both ppc32 and ppc64 have a
flush_dcache_range(), but they're subtly different: it uses dcbf on
ppc32 and dcbst on ppc64, ppc64 has a flush_inval_dcache_range() which
uses dcbf.  These too should be merged and consolidated later.
	- Also flush_dcache_range() was defined in cacheflush.h on
ppc64, and in cache.h on ppc32.  In the merged version it's in
cacheflush.h
	- On ppc32 flush_icache_range() is a normal function from
misc.S.  On ppc64, it was wrapper, testing a feature bit before
calling __flush_icache_range() which does the actual flush.  This
patch takes the ppc64 approach, which amounts to no change on ppc32,
since CPU_FTR_COHERENT_ICACHE will never be set there, but does mean
renaming flush_icache_range() to __flush_icache_range() in
arch/ppc/kernel/misc.S and arch/powerpc/kernel/misc_32.S
	- The PReP register info from asm-ppc/cache.h has moved to
arch/ppc/platforms/prep_setup.c
	- The 8xx register info from asm-ppc/cache.h has moved to a
new asm-powerpc/reg_8xx.h, included from reg.h
	- flush_dcache_all() was defined on ppc32 (only), but was
never called (although it was exported).  Thus this patch removes it
from cacheflush.h and from ARCH=powerpc (misc_32.S) entirely.  It's
left in ARCH=ppc for now, with the prototype moved to ppc_ksyms.c.

Built for Walnut (ARCH=ppc), 32-bit multiplatform (pmac, CHRP and PReP
ARCH=ppc, pmac and CHRP ARCH=powerpc).  Built and booted on POWER5
LPAR (ARCH=powerpc and ARCH=ppc64).

memory and then set up a V->P mapping.

physical memory ranges to fail if the memory is already claimed.

172ca92618 [PATCH] ppc64: PCI error event dispatcher
12-eeh-event-dispatcher.patch

ppc64: EEH Recovery dispatcher thread

This patch adds a mechanism to create recovery threads when an
EEH event is received.  Since an EEH freeze state may be detected
within an interrupt context, we need to get out of the interrupt
context before starting recovery. This dispatcher does this in
two steps: first, it uses a workqueue to get out, and then
lanuches a kernel thread, so that the recovery routine can
sleep for exteded periods without upseting the keventd.

A kernel thread is created with each EEH event, rather than
having one long-running daemon started at boot time.  This is
because it is anticipated that EEH events will be very rare
(very very rare, ideally) and so its pointless to cluter the
process tables with a daemon that will almost never run.

76e6faf7a3 [PATCH] ppc64: avoid PCI error reporting for empty slots
06-eeh-empty-slot-error.patch

Performing PCI config-space reads to empty PCI slots can lead to reports of
"permanent failure" from the firmware. Ignore permanent failures on empty slots.

177bc9367e [PATCH] ppc64: PCI error rate statistics
04-eeh-statistics.patch

This minor patch adds some statistics-gathering counters that allow the
behaviour of the EEH subsystem o be monitored. While far from perfect,
it does provide a rudimentary device that makes understanding of the
current state of the system a bit easier.

56b0fca3a0 [PATCH] ppc64: PCI address cache minor fixes
03-eeh-addr-cache-cleanup.patch

This is a minor patch to clean up a buglet related to the PCI address cache.
(The buglet doesn't manifes itself unless there are also bugs elsewhere,
which is why its minor.).  Also:

-- Improved debug printing.
-- Declare some private routines as static
-- Adds reference counting to struct pci_dn->pcidev structure

02-eeh-minor-cleanup.patch

This patch performs some minor cleanup of the eeh.c file, including:
-- trim some trailing whitespace
-- remove extraneous #includes
-- use the macro PCI_DN uniformly, instead of the void pointer chase.
-- typos in comments
-- improved debug printk's

ae65a391ca [PATCH] ppc64: uniform usage of bus unit id interfaces
01-pci-dn-uniformization.patch

This patch changes the rtas_pci interface to use the new struct pci_dn
structure for two routines that work with pci device nodes.

This patch also does some minor janitorial work: it uses some handy macros
and cleans up some trailing whitespace in the affected file.

77ac166fba [PATCH] ppc64: Don't panic when early __ioremap fails
Early calls to __ioremap() will panic if the hash insertion fails. This
patch makes them return NULL instead. It happens with some pSeries users
who enabled CONFIG_BOOTX_TEXT. The later is getting an incorrect address
for the fame buffer and the hash insertion fails. With this patch, it
will display an error instead of crashing at boot.

681c774d0f [PATCH] ppc64 boot: remove sysmap from required filenames
A stripped vmlinux does not contain enough symbols to recreate the
System.map.  The System.map file is only used to determine the end of
the runtime memory size.  This is the same value (rounded up to
PAGE_SIZE) as ->memsiz in the ELF program header.

Also, the target vmlinux.initrd doesnt work in 2.6.14:

  arch/ppc64/boot/addRamDisk arch/ppc64/boot/ramdisk.image.gz vmlinux.strip arch/ppc64/boot/vmlinux.initrd
  Name of vmlinux output file missing.
