cx18: Move DVB buffer transfer handling from irq handler to work_queue thread.
In order to properly lock the epu2cpu mailbox for driver to CX23418 commands,
the DVB/TS buffer handling needs to be moved from the IRQ handler and IRQ
context to a work queue.  This work_queue implmentation is strikingly similar
to the ivtv implementation - for better or worse.

cx18: Use correct Mailbox IRQ Ack values and misc IRQ handling cleanup.
The SCB field definitions for Ack IRQ's for mailboxes were inconsistent with
the bitmasks being loaded into those SCB fields and the SW2 Ack IRQ handling
logic.  Renamed fields in SCB to make things consistent and did misc IRQ
handling cleanups: removing legacy ivtv dma_reg_lock, HPU IRQ flags, etc.

8268c8f545 V4L/DVB (9492): unplug oops from dvb_frontend_init...
When inadvertently hot-unplugging a WT-220U USB DVB-T receiver with
2.6.24, I was met with an oops [1]. The problem is relevant to
2.6.25/26-rc also.

dvb_frontend_init() was called either from re-creation of the kdvb-fe0
thread - seems unlikely, or someone called
dvb_frontend_reinitialise(), causing this path in the thread - really
unlikely, as I can't find any call-site for it.

Either way, quite a number of drivers call dvb_usb_generic_rw() [2]
without checking the validity of the relevant member in the
dvb_usb_device struct - which had changed. Having dvb_usb_generic_rw()
sanity-check and fail (rather than loading from 0x120) seems
reasonable defensive programming [3], in light of it being called in
this way.

The problem with this, is that drivers don't check the return code of
the init call [4]. Does it make sense to cook a patch which allows the
failure to be propagated back up, or am I missing something else?

Thanks,
  Daniel

0e8bac9791 V4L/DVB (9357): cx88-dvb: Fix Oops in case i2c bus failed to register
There already is an report at kernel bugzilla about this issue:
http://bugzilla.kernel.org/show_bug.cgi?id=9455

When enabling extra checks for the i2c-bus of cx88 based cards by
loading i2c_algo_bit with bit_test=1 this may trigger an oops
when loading cx88_dvb.

This is caused by the extra check code that detects that the
sda-line is stuck high and thus does not register the i2c-bus.

cx88-dvb however does not check if the i2c-bus is valid and just
uses core->i2c_adap to attach dvb frontend modules.
This leads to an oops at the first call to i2c_transfer:

$ modprobe i2c_algo_bit bit_test=1

d522af581c V4L/DVB (9356): [PATCH] saa7134: fix resource map sanity check conflict
Impact: driver could possibly stomp on resources outside of its scope

{mchehab@redhat.com: I got two versions of the same patch (identical,
except for whitespacing). One authored by Andy Burns and another
authored by Suresh Siddha. Due to that, I'm applying the one that has
less CodingStyle errors. I'm also adding both comments and the SOB's for
both patches, since they are both interesting}

Suresh Siddha commented:

  Alexey Fisher reported:

  > resource map sanity check conflict: 0xcfeff800 0xcff007ff 0xcfe00000
  > 0xcfefffff PCI Bus 0000:01

  BAR base is located in the middle of the 4K page and the hardcoded
  size argument makes the request span two pages causing the conflict.

  Fix the hard coded size argument in ioremap().

Andy Burns commented:

  I have already sent this patch on the linux-dvb list, but it didn't get
  much attention, so re-sending direct, I hope you all don't mind.

  While attempting to run mythtv in a xen domU, I encountered problems
  loading the driver for my saa7134 card, with an error from ioremap().

  This error was due to the driver allocating an incorrectly sized mmio
  area, which was trapped by xen's permission checks, but this would go
  un-noticed on a kernel without xen.

  My card has a 1K sized mmio area, I've had information that other cards
  have 2K areas, perhaps others have different sizes, yet the driver
  always attempts to map 4K.  I realise that the granularity of mapping is
  the page size, which typically would be 4K, but unless the card's base
  address happens to fall on a 4K boundary (mine does not) then the
  base+4K will end up spanning two pages, and this is when the error
  occurs under xen.

  My patch uses the pci_resource_len macro to determine the size required
  for the user's particular card, instead of the hardcoded 4K value. I've
  tested with a couple of printk() inside ioremap() that the start address
  and size do get rounded to the closest page boundary.

  With this patch I am able to successfully load the saa7134 driver and
  run mythtv under xen with my card, subject to correct pollirq settings
  in case of shared IRQ, I am still seeing occasional DMA panics, which I
  think are related to swiotlb handling by dom0/domU, usually the panic
  occurs when changing mux, once tuned to a mux, 12 hour continuous
  recordings are possible without errors.

This allows multiple gate_enable/disable's in the tuner_read/write

eventually leading to better results. As a side effect demods that
detect the STOP bit for auto closing of the gate can be avoided, thereby
a very minimal gain in disabling the auto detect feature as well.

5d5254f0d3 timers: handle HRTIMER_CB_IRQSAFE_UNLOCKED correctly from softirq context
Impact: fix incorrect locking triggered during hotplug-intense stress-tests

While migrating the the CB_IRQSAFE_UNLOCKED timers during a cpu-offline,
we queue them on the cb_pending list, so that they won't go
stale.

Thus, when the callbacks of the timers run from the softirq context,
they could run into potential deadlocks, since these callbacks
assume that they're running with irq's disabled, thereby annoying
lockdep!

Fix this by emulating hardirq context while running these callbacks from
the hrtimer softirq.
