parisc: fix find_extend_vma() breakage
The STACK_GROWSUP case of stack expansion was missing a test for 'prev',
which got removed by commit
cb8f488c33539f096580e202f5438a809195008f
("mmap.c: deinline a few functions") by mistake.
I found my original email in "sent" folder. The patch in that mail
does NOT remove !prev. That change had beed added by someone else.
Ok, I think we are not much interested in who did it, let's
fix it for good.

ACPI: pci_link: remove acpi_irq_balance_set() interface
This removes the acpi_irq_balance_set() interface from the PCI
interrupt link driver.
x86 used acpi_irq_balance_set() to tell the PCI interrupt link
driver to configure links to minimize IRQ sharing. But the link
driver can easily figure out whether to turn on IRQ balancing
based on the IRQ model (PIC/IOAPIC/etc), so we can get rid of
that external interface.
It's better for the driver to figure this out at init-time. If
we set it externally via the x86 code, the interface reduces
modularity, and we depend on the fact that acpi_process_madt()
happens before we process the kernel command line.

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

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:

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}

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.

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

sort-of get away with only fiddling with the master interface's

Since it makes no sense to keep the master interface's allmulti or

net: fix setting of skb->tail in skb_recycle_check()
Since skb_reset_tail_pointer() reads skb->data, we need to set
skb->data before calling skb_reset_tail_pointer(). This was causing
spurious skb_over_panic()s from skb_put() being called on a recycled
skb that had its skb->tail set to beyond where it should have been.
