ARM: OMAP4460/4470: PMU: Enable PMU for OMAP4460/70
OMAP4460 and OMAP4470 devices have dedicated PMU interrupts and so add these
interrupts to the MPU HWMOD so we can use these for PMU events on these
devices. The PMU interrupts need to be the first interrupts in the array of
interrupts as the ARM PMU driver assumes this.
By using these dedicated interrupts we only need to enable the MPU and DEBUG
sub-systems for PMU to work. This is different to OMAP4430 that did not have
dedicated interrupts and required other power domains in addition to the DEBUG
sub-system to be enabled so we could route the PMU events to the CTI interrupts.
Hence, OMAP4460 and OMAP4470 devices can use the same list of HWMODs to create
the PMU device that is using by OMAP3.

ARM: OMAP2+: PMU: Add runtime PM support
The original implementation of this patch was done by Ming Lei for PMU on OMAP4
[1]. Since then the PM runtime calls have been moved into the ARM PMU code and
this greatly simplifies the changes.
The another differnce since the original version, is that it is no longer
necessary to call pm_runtime_get/put during the PMU initialisation was we are no
longer accessing the hardware at this stage.
By adding runtime PM support, we can ensure that the appropriate power and clock
domains are kept on while PMU is being used.

the clockdomain is idle. Add a workaround flag in the clockdomain
code, CLKDM_MISSING_IDLE_REPORTING, to deal with this problem, and add
the code necessary to support it.
If CLKDM_MISSING_IDLE_REPORTING is set on a clockdomain, the
clockdomain will be forced active whenever an IP block inside that
clockdomain is in use, even if the clockdomain supports
hardware-supervised idle. When the kernel indicates that the last
active IP block inside the clockdomain is no longer used, the
clockdomain will be forced idle, or, if that mode is not supported in
the hardware, it will be placed into hardware-supervised idle.

On OMAP4 most modules/hwmods support module level context status. On
OMAP3 and earlier, we relied on the power domain level context status.
Identify all modules that don't support 'context_offs' by adding a
flag bit, HWMOD_OMAP4_NO_CONTEXT_LOSS_BIT. Rest have a valid
'context_offs' populated in .prcm structure already.

ARM: OMAP4: hwmod data: add support for lostcontext_mask
Currently hwmod only provides the offset for the context lose
register, and if we attempt to share the same register between two or
more hwmods, the resulting context loss counts get wrong. Thus, we
need a way to specify which bits are used for the context loss
information for each. This is accomplished by adding a new field to
the omap4 prcm struct, 'lostcontext_mask', which specifies a bit-mask
to use for filtering the register.
Mark the affected hwmods appropriately. 'l4_abe' hwmod uses the
LOSTMEM_AESSMEM bit of RM_ABE_AESS_CONTEXT register, as l4_abe doesn't
have its own dedicated register for this purpose. This register is
shared with 'aess' hwmod, thus both hwmods must also specify which
bits of the register are used for them.
This patch only adds the hwmod data, but a future patch should add
code support such that only the specified bits are read and cleared by
the context lose counter update code. If a hwmod doesn't specify
'lostcontext_mask' (default behavior), the whole contents of the
context register should be used without any filtering.

ARM: OMAP4: powerdomain: add support for reading prev logic and mem states
On OMAP4, there is no support to read previous logic state
or previous memory state achieved when a power domain transitions
to RET. Instead there are module level context registers.
In order to support the powerdomain level logic/mem_off_counters
on OMAP4, instead use the previous power state achieved (RET) and
the *programmed* logic/mem RET state to derive if a powerdomain lost
logic or did not.
If the powerdomain is programmed to enter RET state and lose logic
in RET state, knowing that the powerdomain entered RET is good enough
to derive that the logic was lost as well, in such cases.

ARM: OMAP2+: hwmod code: convert missing clockdomain warnings to debug messages
The decision was made a few months ago to allow struct omap_hwmod
records and struct clk records to omit clockdomain information if the
clockdomain is not software-controllable. See for example commit
868c157df9721675c19729eed2c96bac6c3f1d01 ("ARM: OMAP2+: hwmod: remove
prm_clkdm, cm_clkdm; allow hwmods to have no clockdomain").
So convert an existing pr_warning() to a pr_debug() (regarding missing
clockdomains in clocks), and add a pr_debug() for missing hwmod
clockdomains. It's still useful to enable these messages for
debugging, since missing clockdomains can cause hard-to-debug problems
with power management; see for example commit
6c4a057bffe9823221eab547e11fac181dc18a2b ("ARM: OMAP4: clock data:

7a623c039 ("edac: rewrite the sysfs code to use struct

leak, out-of-bound reads etc.):
L422: The iterator "chn" and bound "tot_channels" are totally wrong. Should be
"row" and "tot_csrows" respectively. Which means either memory leak, or
out-of-bound reads (which if does not trigger an immediate page fault
error, will further lead to kfree() on random addresses).
L425: The inner loop is reusing the same iterator "chn" as the outer loop,
which could lead to premature end of the outer loop, and hence memory leak.
L429: The array index 'i' in mci->csrows[i] is a temporary value used in
previous loops, and won't change at all in the current loop. Which
means either out-of-bound read and possibly kfree(random number), or the
same mci->csrows[i] get freed once and again, and possibly double free
for the kfree(csr) in L427.
L426/L427: a kfree(csr->channels) is needed in between to avoid leaking the memory.

de3910eb ("edac: change the mem
allocation scheme to make Documentation/kobject.txt happy") in the 3.6-rc1

As part of Common Clk Framework (CCF) the clk_enable() operation
was split into a clk_prepare() which could sleep, and a clk_enable()
which should never sleep. Similarly the clk_disable() was
split into clk_disable() and clk_unprepare(). This was
needed to handle complex cases where in a clk gate/ungate
would require a slow and a fast part to be implemented.
None of the clocks below seem to be in the 'complex' clocks
category and are just simple clocks which are enabled/disabled
through simple register writes.
Most of the instances also seem to be called in non-atomic
context which means its safe to move all of those from
using a clk_enable() to clk_prepare_enable() and clk_disable() to
clk_disable_unprepare().
For some others, mainly the ones handled through the hwmod framework
there is a possibility that they get called in either an atomic
or a non-atomic context.
The way these get handled below work only as long as clk_prepare
is implemented as a no-op (which is the case today) since this gets
called very early at boot while most subsystems are unavailable.
Hence these are marked with a *HACK* comment, which says we need
to re-visit these once we start doing something meaningful with
clk_prepare/clk_unprepare like doing voltage scaling or something
that involves i2c.

the clock is in the Wake-up, ABE or PER domain. So when we look-up the dmtimer's
"timer_sys_ck" we need to specify the timer device name as well as clock alias
to find the right clock.
Currently, the device names for the timers have the format "omap_timer.X" where
X is the timer instance number. When using to device tree, the format of the
device name created by device-tree is different and has the format
"<reg-address>.<device-name>" (this is assuming that the device-tree "reg"
property is specified). This causes the look-up for the OMAP4 "timer_sys_ck" to
fail. To fix this add new timer clock alias for using device-tree.
Please note that adding a 2nd set of clock aliases for the same clocks to only
temporary until device-tree migration is complete. Then we can remove the legacy
aliases. Hence, I have marked the legacy aliases with a "TODO" to remove them.

In commit c59b537 (ARM: OMAP2+: Simplify dmtimer clock aliases) new clock

clock flag as CK_243X instead of CK_242X. This did not introduce a regression

HID: Fix logitech-dj: missing Unifying device issue
This patch fixes an issue introduced after commit
4ea5454203d991ec
("HID: Fix race condition between driver core and ll-driver").
After that commit, hid-core discards any incoming packet that arrives while
hid driver's probe function is being executed.
This broke the enumeration process of hid-logitech-dj, that must receive
control packets in-band with the mouse and keyboard packets. Discarding mouse
or keyboard data at the very begining is usually fine, but it is not the case
for control packets.
This patch forces a re-enumeration of the paired devices when a packet arrives
that comes from an unknown device.
Based on a patch originally written by Benjamin Tissoires.

"More bug fixes, nothing gets past these guys"
1) More kernel info leaks found by Mathias Krause, this time in the
IPSEC configuration layers.
2) When IPSEC policies change, we do not properly make sure that cached
routes (which could now be stale) throughout the system will be
revalidated. Fix this by generalizing the generation count
invalidation scheme used by ipv4. From Nicolas Dichtel.
3) When repairing TCP sockets, we need to allow to restore not just the
send window scale, but the receive one too. Extend the existing
interface to achieve this in a backwards compatible way. From
Andrey Vagin.
4) A fix for FCOE scatter gather feature validation erroneously caused
scatter gather to be disabled for things like AOE too. From Ed L
Cashin.
5) Several cases of mishandling of error pointers, from Mathias Krause,
Wei Yongjun, and Devendra Naga.
6) Fix gianfar build, from Richard Cochran.
7) CAP_NET_* failures should return -EPERM not -EACCES, from Zhao
Hongjiang.
8) Hardware reset fix in janz-ican3 CAN driver, from Ira W Snyder.
9) Fix oops during rmmod in ti_hecc CAN driver, from Marc Kleine-Budde.
10) The removal of the conditional compilation of the clk support code
in the stmmac driver broke things. This is because the interfaces
used are the ones that don't also perform the enable/disable of the
clk. Fix from Stefan Roese.
11) The QFQ packet scheduler can record out of range virtual start
times, resulting later in misbehavior and even crashes. Fix from
Paolo Valente.
12) If MSG_WAITALL is used with IOAT DMA under TCP, we can wedge the
receiver when the advertised receive window goes to zero. Detect
this case and force the processing of the IOAT DMA queue when it
happens to avoid getting stuck. Fix from Michal Kubecek.
13) batman-adv assumes that test_bit() returns only 0 or 1, but this is
not true for x86 (which returns -1 or 0, via the 'sbb' instruction).
Fix from Linus Lussing.
14) Fix small packet corruption in e1000, from Tushar Dave.
15) make_blackhole() in the IPSEC policy code can do one read unlock too
many, fix from Li RongQing.
16) The new tcp_try_coalesce() code introduced a bug in TCP URG
handling, fix from Eric Dumazet.
17) Fix memory leak in __netif_receive_skb() when doing zerocopy and
when hit an OOM condition. From Michael S Tsirkin.
18) netxen blindly deferences pdev->bus->self, which is not guarenteed
to be non-NULL. Fix from Nikolay Aleksandrov.
