Currently the bootloader enabled V28 is kept on but this may change in the

Also if there are any consumers on the V28 domain doing regulator_enable

OMAP: PM constraints: add omap_pm_set_min_clk_rate()
Add omap_pm_set_min_clk_rate(). This constraint is meant for use by
device drivers to translate a certain device-specific performance
constraint (e.g., "minimum polygons per second") to a clock rate for
the driver's device, given the driver's intimate knowledge of the
device hardware (e.g., device type, device hardware revision, firmware
revision, etc.) From a general PM core perspective, clock rate is
probably the closest general analog to "performance" that is
available, but the exact mapping from a use-case-specific performance
constraint to clock rate must be done by the driver. Drivers intended for
upstream merging shouldn't hardcode specific clock rates in their code
without basing those rates on some performance criteria requested through
the driver's subsystem (ideally, from userspace).
Imre Deak <imre.deak@nokia.com> described the need and use-case for
this constraint, and discussed the implementation - thanks, Imre.

OMAP: PM constraints: add return values; add requesting device param to omap_pm_set_max_dev_wakeup_lat()
Add return values to the PM constraint functions. This allows the PM
core to provide feedback to the caller if a constraint is not
possible. Update the one upstream user of omap_pm_set_max_mpu_wakeup_lat()
to add a compatibility wrapper, needed until the driver is changed.
Update some of the documentation to conform more closely to kerneldoc style.
Add an additional device parameter to omap_pm_set_max_dev_wakeup_lat()
to identify the device requesting the constraint. This is so repeated calls
to omap_pm_set_max_dev_wakeup_lat() with the same requesting device can
override the device's previously-set constraint. Also, it allows the PM
core to make a decision as to whether or not the constraint should be
satisfied, based on the caller's identity.

OMAP: hwmod/device: add omap_{device,hwmod}_get_mpu_rt_va
Add omap_device_get_mpu_rt_va(). This is intended to be used by
device drivers (currently, via a struct platform_data function
pointer) to retrieve their corresponding device's virtual base address
that the MPU should use to access the device. This is needed because
the omap_hwmod code does its own ioremap(), in order to gain access to
the module's OCP_SYSCONFIG register.
Add omap_hwmod_get_mpu_rt_va(). omap_device_get_mpu_rt_va() calls this
function to do the real work.
While here, rename struct omap_hwmod._rt_va to struct
omap_hwmod._mpu_rt_va, to reinforce that it refers to the MPU's
register target virtual address base (as opposed to, for example, the
L3's).
In the future, this belongs as a function in an omap_bus, so it is not

We need to wait on the IDLEST bit after the clocks are enabled

while the USBTLL f-clock ops uses clkops_omap2_dflt. If the

short-circuited as the companion f-clock is not enabled.
This can cause a data abort if the IDLEST has not transitioned,

futex: futex_find_get_task remove credentails check
futex_find_get_task is currently used (through lookup_pi_state) from two
contexts, futex_requeue and futex_lock_pi_atomic. None of the paths
looks it needs the credentials check, though. Different (e)uids
shouldn't matter at all because the only thing that is important for
shared futex is the accessibility of the shared memory.
The credentail check results in glibc assert failure or process hang (if
glibc is compiled without assert support) for shared robust pthread
mutex with priority inheritance if a process tries to lock already held
lock owned by a process with a different euid:
pthread_mutex_lock.c:312: __pthread_mutex_lock_full: Assertion `(-(e)) != 3 || !robust' failed.
The problem is that futex_lock_pi_atomic which is called when we try to
lock already held lock checks the current holder (tid is stored in the
futex value) to get the PI state. It uses lookup_pi_state which in turn
gets task struct from futex_find_get_task. ESRCH is returned either
when the task is not found or if credentials check fails.
futex_lock_pi_atomic simply returns if it gets ESRCH. glibc code,
however, doesn't expect that robust lock returns with ESRCH because it
should get either success or owner died.

USB: obey the sysfs power/wakeup setting

(commit
5f677f1d45b2bf08085bbba7394392dfa586fa8e "USB: fix remote
wakeup settings during system sleep"). After hearing from a user, I
realized that remote wakeup should be enabled during system sleep
whenever userspace allows it, and not only if a driver requests it
too.
Indeed, there could be a device with no driver, that does nothing but
generate a wakeup request when the user presses a button. Such a
device should be allowed to do its job.
The problem fixed by the earlier patch -- device generating a wakeup
request for no reason, causing system suspend to abort -- was also
addressed by a later patch ("USB: don't enable remote wakeup by
default", accepted but not yet merged into mainline). The device
won't be able to generate the bogus wakeup requests because it will be
disabled for remote wakeup by default. Hence this reversion will not
re-introduce any old problems.

USB: gadget eth: Fix calculate CRC32 in EEM
CRC should be calculated for Ethernet frame, not for whole recievede EEM data.
This bug shows rarely, because in many times len == skb->len.

USB: gadget/printer, fix sleep inside atomic
Stanse found that sleep is called inside atomic context created by
lock_printer_io spinlock in several functions. It's used in process
context only and some functions sleep inside its critical section. As
this is not allowed for spinlocks, switch it to mutex.

USB: isp1362-hcd, fix double lock
Stanse found that isp1362_sw_reset tries to take a isp1362_hcd->lock,
but it is already held in isp1362_hc_stop. Avoid that by introducing
__isp1362_sw_reset which doesn't take the lock and call it from
isp1362_hc_stop. isp1362_sw_reset is then as simple as lock --
__isp1362_sw_reset -- unlock.

USB: serial: ftdi: correct merge conflict with CONTEC id
This patch corrects a problem with the merge of a previous
patch to add the CONTEC identifier.
I believe the merge problem occurred with the commit:
dee5658b482e9e2ac7d6205dc876fc11d4008138
Originally I submitted a patch and then they asked me to order the IDs
and resubmit, so did I. But unfortunately in the end somehow both
patches were merged.

USB: fix oops in usb_sg_init()
This patch (as1401) fixes a bug in usb_sg_init() that can cause an
invalid pointer dereference. An inner loop reuses some local variables
in an unsafe manner, so new variables are introduced.
