Drivers: hv: Implement routines for read side signaling optimization
Implement functions that will support read-side signaling optimization.
By having the reader indicate the start of the "read" operation and the
"end" of the read operation we can more efficiently handle the signaling
protocol: while the read is in progress, there is no need for the "writer"
to signal the "reader" as new items are put on the read queue.

drivers/w1/masters/mxc_w1.c: use devm_ functions
The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
At the same time, this fixes two faults. First, mdev, the result of
kzalloc, was never freed. Second, on failure of ioremap, 0 was returned.
This has been replaced by -EBUSY, which was the failure value for the call
to request_mem_region, with which the call to ioremap has been combined.
The warning message on failure of ioremap is dropped, because
devm_request_and_ioremap already gives such messages on failure.
Finally, the initial call to platform_get_resource is moved closer to the
call to devm_request_and_ioremap, which takes care of checking whether its
result is NULL, implying that a test on the result of this call to
platform_get_resource is not needed.

Merge tag 'omap-for-v3.8-rc2/fixes-signed-v2' of git://git./linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
The biggest change is a fix to deal with different power state
on omap2 registers that causes issues trying to use common PM code.
Also fix few incorrect registers, and an issue for omap1 USB, and
few sparse fixes for issues that sneaked in with all the clean-up.

drm/ttm: fix fence locking in ttm_buffer_object_transfer
Noticed while reviewing the fence locking in the radeon pageflip
handler.
v2: Instead of grabbing the bdev->fence_lock in object_transfer just
move the single callsite of that function a few lines, so that it is
protected by the fence_lock. Suggested by Jerome Glisse.

ARM: highbank: fix secondary boot and hotplug
With commit 384a290 (ARM: gic: use a private mapping for CPU target
interfaces), wake-up IPIs now go to all cores as the gic cpu interface
numbering may not follow core numbering. This broke secondary boot on
highbank since the boot address was already set for all secondary cores,
this caused all cores to boot before the kernel was ready.
Fix this by moving the setting of the jump address to
highbank_boot_secondary instead of highbank_smp_prepare_cpus and
highbank_cpu_die. Also, clear the address when we boot. This prevents
cores from booting before they are actually triggered and is also necessary
to get suspend/resume to work.
