- conversion of amba-pl08x.c to use these helper functions.
- addition of OMAP DMA engine driver (using these helper functions),

Nothing in the helper functions is ARM specific, so I hope that other
implementations can consolidate some of their code by making use of
these helpers.
This has been sitting in linux-next most of the merge cycle, and has
been tested by several OMAP folk. I've tested it on sa11x0 platforms,

block: add partition resize function to blkpg ioctl
Add a new operation code (BLKPG_RESIZE_PARTITION) to the BLKPG ioctl that
allows altering the size of an existing partition, even if it is currently
in use.
This patch converts hd_struct->nr_sects into sequence counter because
One might extend a partition while IO is happening to it and update of
nr_sects can be non-atomic on 32bit machines with 64bit sector_t. This
can lead to issues like reading inconsistent size of a partition. Sequence
counter have been used so that readers don't have to take bdev mutex lock
as we call sector_in_part() very frequently.
Now all the access to hd_struct->nr_sects should happen using sequence
counter read/update helper functions part_nr_sects_read/part_nr_sects_write.
There is one exception though, set_capacity()/get_capacity(). I think
theoritically race should exist there too but this patch does not
modify set_capacity()/get_capacity() due to sheer number of call sites
and I am afraid that change might break something. I have left that as a
TODO item. We can handle it later if need be. This patch does not introduce
any new races as such w.r.t set_capacity()/get_capacity().

block: do not artificially constrain max_sectors for stacking drivers
blk_set_stacking_limits is intended to allow stacking drivers to build
up the limits of the stacked device based on the underlying devices'

doesn't allow the stacking driver to inherit a max_sectors larger than
1024 -- due to blk_stack_limits' use of min_not_zero.
It is now clear that this artificial limit is getting in the way so
change blk_set_stacking_limits's max_sectors to UINT_MAX (which allows
stacking drivers like dm-multipath to inherit 'max_sectors' from the

Commit
ca5481c68e9fbcea62bb3c78ae6cccf99ca8fb73 ("sh: pfc: Rudimentary
pinctrl-backed GPIO support.") introduced a regression for platforms that
were doing early GPIO API calls (from arch_initcall() or earlier),
leading to a situation where our two-stage registration logic would trip
itself up and we'd -ENODEV out of the pinctrl registration path,
resulting in endless -EPROBE_DEFER errors. Further lack of checking any
sort of errors from gpio_request() resulted in boot time warnings,
tripping on the FLAG_REQUESTED test-and-set in gpio_ensure_requested().
As it turns out there's no particular need to bother with the two-stage
registration, as the platform bus is already available at the point that
we have to start caring. As such, it's easiest to simply fold these
together in to a single init path, the ordering of which is ensured
through the platform's mux registration, as usual.

Merge tag 'nfs-for-3.6-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull second wave of NFS client updates from Trond Myklebust:
- Patches from Bryan to allow splitting of the NFSv2/v3/v4 code into
separate modules.
- Fix Oopses in the NFSv4 idmapper
- Fix a deadlock whereby rpciod tries to allocate a new socket and ends
up recursing into the NFS code due to memory reclaim.
- Increase the number of permitted callback connections.

Merge git://git./linux/kernel/git/davem/net
Pull networking update from David S. Miller:
"I think Eric Dumazet and I have dealt with all of the known routing
cache removal fallout. Some other minor fixes all around.
1) Fix RCU of cached routes, particular of output routes which require
liberation via call_rcu() instead of call_rcu_bh(). From Eric
Dumazet.
2) Make sure we purge net device references in cached routes properly.
3) TG3 driver bug fixes from Michael Chan.
4) Fix reported 'expires' value in ipv6 routes, from Li Wei.
5) TUN driver ioctl leaks kernel bytes to userspace, from Mathias
Krause."

rtc/rtc-88pm80x: remove unneed devm_kfree
devm_kzalloc() doesn't need a matching devm_kfree(), the freeing mechanism
will trigger when driver unloads.

rtc/rtc-88pm80x: assign ret only when rtc_register_driver fails
At the probe we are assigning ret to return value of PTR_ERR right after
the rtc_register_drive()r, as we would have done it in the if
(IS_ERR(ptr)) check, since the function fails and goes inside that case
