274b89ca3b iwlagn: fix HW crypto for TX-only keys
Group keys in IBSS or AP mode are not programmed
into the device since we give the key to it with
every TX packet. However, we do need mac80211 to
create the MMIC & PN in all cases. Move the code
around to set the key flags all the time. We set
them even when the key is removed again but that
is obviously harmless.

de28f25e82 clockevents: Set noop handler in clockevents_exchange_device()
If a device is shutdown, then there might be a pending interrupt,
which will be processed after we reenable interrupts, which causes the
original handler to be run. If the old handler is the (broadcast)
periodic handler the shutdown state might hang the kernel completely.

550acb1926 genirq: Fix race condition when stopping the irq thread
In irq_wait_for_interrupt(), the should_stop member is verified before
setting the task's state to TASK_INTERRUPTIBLE and calling schedule().
In case kthread_stop sets should_stop and wakes up the process after
should_stop is checked by the irq thread but before the task's state
is changed, the irq thread might never exit:

kthread_stop                    irq_wait_for_interrupt
------------                    ----------------------

                                 ...
...                              while (!kthread_should_stop()) {
kthread->should_stop = 1;
wake_up_process(k);
wait_for_completion(&kthread->exited);
...
                                     set_current_state(TASK_INTERRUPTIBLE);

                                     ...

                                     schedule();
                                 }

Fix this by checking if the thread should stop after modifying the
task's state.

bab9efc206 vmwgfx: integer overflow in vmw_kms_update_layout_ioctl()
There are two issues in vmw_kms_update_layout_ioctl().  First, the
for loop forgets to index rects and only checks the first element.
Second, there is a potential integer overflow if userspace passes
in a large arg->num_outputs.  The call to kzalloc() would allocate
a small buffer, leading to out-of-bounds read.

6eebd6bb5f drm: Fix lack of CRTC disable for drm_crtc_helper_set_config(.fb=NULL)
Disabling the CRTC by setting its framebuffer to NULL, as used by
drm_framebuffer_cleanup(), was failing to pass the current framebuffer
to the crtc_func->disable callback. This is because of the dance within
drm_crtc_helper_set_config to pass the new_fb (NULL in this case) to the
drm_crtc_helper_set_mode with the currently attached fb as a parameter.
drm_crtc_helper_set_mode treats this as a no-op and the encoder is still
enabled. And so the current fb is forgotten before the call to
drm_helper_disable_unused_functions.

This patch treats disabling the CRTC as a simple special case rather
than adding further complexity into the configuration logic.

This fixes a pin-leak of the fb bo on Xserver close.

fc084e0b93 ALSA: sis7019 - give slow codecs more time to reset
There are some AC97 codec and board combinations that have been observed
to take a very long time to respond after the cold reset has completed.
In one case, more than 350 ms was required. To allow users to have sound
on those platforms, we'll wait up to 500ms for the codec to become
ready.

As a board may have multiple codecs, with some faster than others to
reset, we add a module parameter to inform the driver which codecs
should be present.

b29e23547e ARM: OMAP1: Remove unsafe clock values from omap1_defconfig
DPLL1 reprogramming to a different rate is actually blocked inside
omap1_select_table_rate(), resulting in the defalut rate of 60 MHz
always used instead of the one selected in .config. OTOH, in
omap1_defconfig we currently rely on Kconfig options for the supported
MHz rates in case of boards which boot with dpll1 not set correctly by
their boot loaders.

This means that before we allow for reprogramming of dpll1 rate, we
should remove all unsafe clock selections from omap1_defconfig,
otherwise it will stop booting on boards with imperfect boot loaders,
as it would always try to change to 216MHz.

Keep only one safe clock rate per each supported xtal frequency, i.e.
60MHZ dpll1 for 12MHz xtal and 182MHz dpll1 for 13MHz xtal.

BTW, this change goes into the direction of removing all OMAP1 clock
rate options, planned for next merge window.

650f7a72b8 ARM: OMAP1: Fix reprogramming of DPLL1 for systems that boot at rates below 60MHz
Commit e9b7086b80 (ARM: OMAP: Fix
reprogramming of dpll1 rate) fixed a regression for systems that
did not rely on bootloader set rates.

However, it also introduced a new problem where the rates selected
in .config would not take affect as omap1_select_table_rate
currently refuses to reprogram DPLL1 if it's already initialized.

This was not a problem earlier, as the reprogramming was done
earlier with ck_dpll1_p->rate uninitialized.

Fix this by forcing the reprogramming on systems booting at rates
below 60MHz. Note that the long term fix is to make the rates
SoC specific later on.

Thanks for Janusz Krzysztofik <jkrzyszt@tis.icnet.pl> for figuring
this one out.

1ee5fa1e99 sch_red: fix red_change
Le mercredi 30 novembre 2011 à 14:36 -0800, Stephen Hemminger a écrit :

RED is useful for high throughput routers, I doubt many linux machines
act as such devices.

I was considering adding Adaptative RED (Sally Floyd, Ramakrishna
Gummadi, Scott Shender), August 2001

In this version, maxp is dynamic (from 1% to 50%), and user only have to
setup min_th (target average queue size)
(max_th and wq (burst in linux RED) are automatically setup)

By the way it seems we have a small bug in red_change()

if (skb_queue_empty(&sch->q))
	red_end_of_idle_period(&q->parms);

First, if queue is empty, we should call
red_start_of_idle_period(&q->parms);

Second, since we dont use anymore sch->q, but q->qdisc, the test is
meaningless.

Oh well...

[PATCH] sch_red: fix red_change()

Now RED is classful, we must check q->qdisc->q.qlen, and if queue is empty,
we start an idle period, not end it.

939255798a ocfs2: avoid unaligned access to dqc_bitmap
The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned,
but not 64-bit aligned.  The dqc_bitmap is accessed by ocfs2_set_bit(),
ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit().  These
are wrapper macros for ext2_*_bit() which need to take an unsigned long
aligned address (though some architectures are able to handle unaligned
address correctly)

So some 64bit architectures may not be able to access the dqc_bitmap
correctly.

This avoids such unaligned access by using another wrapper functions for
ext2_*_bit().  The code is taken from fs/ext4/mballoc.c which also need to
handle unaligned bitmap access.

This reverts commit 81d54ec847.

If we take the "try_again" goto, due to a checksum error,
the 'len' has already been truncated.  So we won't compute
the same values as the original code did.

b03b6dd58c bridge: master device stuck in no-carrier state forever when in user-stp mode
When in user-stp mode, bridge master do not follow state of its slaves, so
after the following sequence of events it can stuck forever in no-carrier
state:
1) turn stp off
2) put all slaves down - master device will follow their state and also go in
no-carrier state
3) turn stp on with bridge-stp script returning 0 (go to the user-stp mode)
Now bridge master won't follow slaves' state and will never reach running
state.

This patch solves the problem by making user-stp and kernel-stp behavior
similar regarding master following slaves' states.

0de13500ad Revert "xHCI: reset-on-resume quirk for NEC uPD720200"
This reverts commit df711fc996.

The commit added a reset-on-resume quirk because the NEC chipset stopped
responding to commands about 30 minutes after a system resume from
suspend.  We thought it was a chipset issue, but it turns out that the
xHCI driver was zeroing out the link TRB after a successful context
restore during resume.  The host controller would fall off the command
ring sometime later, causing it to not respond to new commands.

The link TRB issue has been fixed with commit
158886cd2c "xHCI: fix bug in
xhci_clear_command_ring()", so revert the reset-on-resume quirk, as it's
not necessary.

Commit df711fc996 was marked for stable
trees back to 2.6.37, but according to my mail, it has not made it into
Linus' tree or the stable trees yet.

158886cd2c xHCI: fix bug in xhci_clear_command_ring()
When system enters suspend, xHCI driver clears command ring by writing zero
to all the TRBs. However, this also writes zero to the Link TRB, and the ring
is mangled. This may cause driver accesses wrong memory address and the
result is unpredicted.

When clear the command ring, keep the last Link TRB intact, only clear its
cycle bit. This should fix the "command ring full" issue reported by Oliver
Neukum.

This should be backported to stable kernels as old as 2.6.37, since the
commit 89821320 "xhci: Fix command ring replay after resume" is merged.
