Move the computation of QP capabilities (max scatter/gather entries,
max inline data, etc) into the kernel, and have the uverbs module
return the values as part of the create QP response. This keeps
precise knowledge of device limits in the low-level kernel driver.
This requires an ABI bump, so while we're making changes, get rid of
the max_sge parameter for the modify SRQ command -- it's not used and
shouldn't be there.

Now that ib_umad uses the new MAD sending interface, it no longer

Change the struct ib_device.resize_cq() method to take a plain integer
that holds the new CQ size, rather than a pointer to an integer that
it uses to return the new size. This makes the interface match the
exported ib_resize_cq() signature, and allows the low-level driver to
update the CQ size with proper locking if necessary.
No in-tree drivers are exporting this method yet.

ib_unregister_mad_agent() completes all pending MAD sends and waits
for the agent's send_handler routine to return. umad's send_handler()
calls queue_packet(), which does down_read() on the port mutex to look
up the agent ID. This means that the port mutex cannot be held for
writing while calling ib_unregister_mad_agent(), or else it will
deadlock. This patch fixes all the calls to ib_unregister_mad_agent()
in the umad module to avoid this deadlock.

Add ibX_path files to debugfs that contain information about the IPoIB
path cache. IPoIB ARP only gives GIDs, which the IPoIB driver must
resolve to real IB paths through the ib_sa module. For debugging,
when the ARP table looks OK but traffic isn't flowing, it's useful to
be able to see if the resolution from GID to path worked.
Also clean up the formatting of the existing _mcg debugfs files.

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.

The problem (eject not working on ATAPI LS-120 drive) is caused by
idefloppy_ioctl() function which *first* tries generic_ide_ioctl()
and *only* if it fails with -EINVAL, proceeds with the specific ioctls.
The generic eject command fails with something other than -EINVAL
and the specific one is never executed.
This patch fixes it by first going through the internal ioctls
and only trying generic_ide_ioctl() if none of them matches.

The siimage driver proports to support the Adaptec SA-1210 SATA
controller. However, at least some of those cards boot-up with their
interrupts disabled internally. The siimage driver currently ignores
that fact, so that driver does not actually work with those cards.
This patch enables those interrupts on cards that need it.

AGP shouldn't use "global_flush_tlb()" to flush the AGP mappings, that i
spurely an x86'ism. The proper AGP mapping flusher that should be used
is "flush_agp_mappings()", which on x86 obviously happens to do a global
TLB flush.
This makes AGP (or at least the config _I_ happen to use) compile again

This patch started life as a response to fedora specific ide subsystem changes
that made error handling of my ATAPI tape drive fail; the specifics are in
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=160868
The insertion of the statement rq->errors = err; near the end of
ide_end_drive_cmd() in drivers/ide/ide-io.c means that rq->errors does not
contain what it needs to in idescsi_end_request() in drivers/scsi/ide-scsi.c
anymore. Recent mainline kernels now also have this change.

A driver must wait 100us before attempting an MMIO operation
to the RISC after a soft-reset has been initiated. A
similar delay was needed with earlier ISPs.
Note: a PCI config-space read is used to flush the MMIO
write to the ISP, since the ISP's state machines are unable
to respond to any MMIO read during the reset process.

Introduce struct platform_driver. This allows the platform device
driver methods to be passed a platform_device structure instead of
instead of a plain device structure, and therefore requiring casting
in every platform driver.
We introduce this in such a way that any existing platform drivers
registered directly via driver_register continue to work as before,
thereby allowing a gradual conversion to the new platform_driver
methods.
