[PATCH] PCI: automatically set device_driver.owner
A nice feature of sysfs is that it can create the symlink from the
driver to the module that is contained in it.
It requires that the device_driver.owner is set, what is not the
case for many PCI drivers.
This patch allows pci_register_driver to set automatically the
device_driver.owner for any PCI driver.

[PATCH] pciehp: clean-up how we request control of hotplug hardware
This patch further tweaks how we request control of hotplug
controller hardware from BIOS. We first search the ACPI namespace
corresponding to a specific hotplug controller looking for an
_OSC or OSHP method. On failure, we successively move to the
ACPI parent object, till we hit the highest level host bridge
in the hierarchy. This allows for different types of BIOS's
which place the _OSC/OSHP methods at various places in the acpi
namespace, while still not encroaching on the namespace of
some other root level host bridge.
This patch also introduces a new load time option (pciehp_force)
that allows us to bypass all _OSC/OSHP checking. Not supporting
these methods seems to be be the most common ACPI firmware problem
we've run into. This will still _not_ allow the pciehp driver to
work correctly if the BIOS really doesn't support pciehp (i.e. if
it doesn't generate a hotplug interrupt). Use this option with
caution. Some BIOS's may deliberately not build any _OSC/OSHP
methods to make sure it retains control the hotplug hardware.
Using the pciehp_force parameter for such systems can lead to
two separate entities trying to control the same hardware.

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.

[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.

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

[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.

[NETLINK]: Generic netlink family
The generic netlink family builds on top of netlink and provides
simplifies access for the less demanding netlink users. It solves
the problem of protocol numbers running out by introducing a so
called controller taking care of id management and name resolving.
Generic netlink modules register themself after filling out their
id card (struct genl_family), after successful registration the
modules are able to register callbacks to command numbers by
filling out a struct genl_ops and calling genl_register_op(). The
registered callbacks are invoked with attributes parsed making
life of simple modules a lot easier.
Although generic netlink modules can request static identifiers,
it is recommended to use GENL_ID_GENERATE and to let the controller
assign a unique identifier to the module. Userspace applications
will then ask the controller and lookup the idenfier by the module
name.
Due to the current multicast implementation of netlink, the number
of generic netlink modules is restricted to 1024 to avoid wasting
memory for the per socket multiacst subscription bitmask.

powerpc: Fix find_next_bit on 32-bit
We had a "64" that didn't get changed to BITS_PER_LONG, resulting
in find_next_bit not working correctly.

ppc/powerpc: workarounds for old Open Firmware versions
This adds code to work around some problems with old versions of
Open Firmware, such as on the early powermacs (7500 etc.) and the
"Longtrail" CHRP machine. On these machines we have to claim
the physical and virtual address ranges explicitly when claiming
memory and then set up a V->P mapping.
The Longtrail has more problems: setprop doesn't work, and we have
to set an "allow-reclaim" variable to 0 in order to get claim on
physical memory ranges to fail if the memory is already claimed.
