Jeff Mahoney 58e78475ec saa7134: fix thread shutdown handling
This patch changes the test for the thread pid from >= 0 to > 0.

When the saa8134 driver initialization fails after a certain point, it goes
through the complete shutdown process for the driver.  Part of shutting it
down includes tearing down the thread for tv audio.

The test for tearing down the thread tests for >= 0.  Since the dev
structure is kzalloc'd, the test will always be true if we haven't tried to
start the thread yet.  We end up waiting on pid 0 to complete, which will
never happen, so we lock up.

This bug was observed in Novell Bugzilla 284718, when request_irq() failed.

Rename struct pci_driver data so that false section mismatch warnings won't

Sam, ISTM that depending on variable names is the weakest & worst part of
modpost section checking.  Should __init_refok work here?  I got build
errors when I tried to use it, probably because the struct pci_driver probe
and remove methods are not marked "__init_refok".

Trent Piepho 59faba1b31 Fix Kconfig dependency problems wrt boolean menuconfigs
If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on
(tristate)BAZ, build problems will result.  If BAZ=m, then BAR can be set
y, which allows FOO=y.  It's possible to have FOO=y && BAZ=m, which
wouldn't be allowed if FOO depended directly on BAZ.  In effect, the bool
promotes the tristate from m to y.

This ends up causing a problem with several menuconfigs that look like:

menuconfig BAR
	bool
	depends on BAZ [tristate]
if BAR
config FOO
	tristate
endif

The solution used here is to add the dependencies of BAR to the if
statement, so that items in the if block will gain a direct
non-bool-promoted dependency on BAZ.  This is how it would work if a menu
was used instead of an if block.

Hugh Dickins 30acbabae3 mm: kill validate_anon_vma to avoid mapcount BUG
validate_anon_vma gave a useful check on the integrity of the anon_vma list
when Andrea was developing obj rmap; but it was not enabled in SLES9
itself, nor in mainline, until Nick changed commented-out RMAP_DEBUG to
configurable CONFIG_DEBUG_VM in 2.6.17.  Now Petr Vandrovec reports that
its BUG_ON(mapcount > 100000) can easily crash a CONFIG_DEBUG_VM=y system.

That limit was just an arbitrary number to protect against an infinite
loop.  We could raise it to something enormous (depending on sizeof struct
vma and size of memory?); but I rather think validate_anon_vma has outlived
its usefulness, and is better just removed - which gives a magnificent
performance boost to anything like Petr's test program ;)

Of course, a very long anon_vma list is bad news for preemption latency,
and I believe there has been one recent report of such: let's not forget
that, but validate_anon_vma only makes it worse not better.

Bjorn Helgaas 172d0496cd PNP SMCf010 quirk: auto-config device if BIOS left it broken
Some HP firmware leaves the SMCf010 IRDA device incompletely configured, or
reports the wrong resources in _CRS.  As a workaround, when we find such a
device, try to auto-configure the device.

This ignores the _CRS data, picks a config from _PRS, and runs _SRS to
configure the device.  This makes smsc-ircc2 work correctly with PNP
resources (with no preconfiguration!) on all the machines I tested.

I think Windows does something like this by default for all devices,
so we should consider doing the same thing in Linux.

This patch addresses part of the 2.6.22 regression:
    "no irda0 interface (2.6.21 was OK), smsc does not find chip"
It fixes smsc-ircc2 PNP device detection on HP nc6000, nc6220, nw8000,
nw8240, and possibly other machines.

Bjorn Helgaas 7c31d2f59c smsc-ircc2: skip preconfiguration for PNP devices
If we rely on the device resources from PNPBIOS, we also have to rely on
the BIOS to configure any bridges on the way to the device.

Using the PNPBIOS resources but changing the configuration of a bridge
behind the back of the firmware is likely to make things inconsistent.

This patch addresses part of the 2.6.22 regression:
    "no irda0 interface (2.6.21 was OK), smsc does not find chip"
It fixes smsc-ircc2 PNP device detection on HP nx5000 laptops.
Other laptops, including HP nc6000, HP nc8000, HP nw8000, and Toshiba
Portege 4000, still need PNP quirks to make this work.

With "smsc-ircc2.nopnp", we do the legacy device probe, including manual
bridge preconfiguration, as before.

Michael Halcrow 240e2df5c7 eCryptfs: fix write zeros behavior
This patch fixes the processes involved in wiping regions of the data during
truncate and write events, fixing a kernel hang in 2.6.22-rc4 while assuring
that zero values are written out to the appropriate locations during events in
which the i_size will change.

The range passed to ecryptfs_truncate() from ecryptfs_prepare_write() includes
the page that is the object of ecryptfs_prepare_write().  This leads to a
kernel hang as read_cache_page() is executed on the same page in the
ecryptfs_truncate() execution path.  This patch remedies this by limiting the
range passed to ecryptfs_truncate() so as to exclude the page that is the
object of ecryptfs_prepare_write(); it also adds code to
ecryptfs_prepare_write() to zero out the region of its own page when writing
past the i_size position.  This patch also modifies ecryptfs_truncate() so
that when a file is truncated to a smaller size, eCryptfs will zero out the
contents of the new last page from the new size through to the end of the last
page.

deadlock. The netpoll_send_skb held the netif_tx_lock, and the poll
routine could acquire it to clean up skb's. Other drivers might use
same locking model.

The driver is correct, netpoll should not introduce more locking
problems than it causes already. So change the code to drop lock
before calling poll handler.

Tejun Heo b9a4197e26 libata: use PIO for non-16 byte aligned ATAPI commands
The IDE driver used DMA for ATAPI commands if READ/WRITE command is
multiple of sector size or sg command is multiple of 16 bytes.  For
libata, READ/WRITE sector alignment is guaranteed by the high level
driver (sr), so we only have to worry about the 16 byte alignment.

This patch makes ata_check_atapi_dma() always request PIO for all data
transfer commands which are not multiple of 16 bytes.

Tejun Heo 55f3952d45 libata: kill the infamous abnormal status message
The infamous abnormal status message triggers on not so abnormal cases
including empty port and even when it's being triggered on actual
errors the info it provides is redundant and out of context - higher
level functions will print the info in better safe later anyway.

Also, by being triggered all the time, it leads people to think that
the abnormality is somehow related to all ATA and system problems
they're experiencing and gives owners of healthy systems unfounded
doubts about the integrity of the universe.  Make it a DPRINTK and
save the universe.

Siddha, Suresh B 48d8d7ee5d x86_64 irq: use mask/unmask and proper locking in fixup_irqs()
Force irq migration path during cpu offline, is not using proper locks and
irq_chip mask/unmask routines.  This will result in some races(especially
the device generating the interrupt can see some inconsistent state,
resulting in issues like stuck irq,..).

Appended patch fixes the issue by taking proper lock and encapsulating
irq_chip set_affinity() with a mask() before and an unmask() after.

This fixes a MSI irq stuck issue reported by Darrick Wong.

There are several more general bugs in this area(irq migration in the
process context). For example,

 1. Possibility of missing edge triggered irq.
 2. Reliable method of migrating level triggered irq in the process context.

We plan to look and close these in the near future.

Eric says:
	In addition even with the fix from Suresh there is still at least one
	nasty hardware race in fixup_irqs().   However we exercise that code
	path rarely enough that we are unlikely to hit it in the real world,
	and that race seems to have existed since the code was merged.  And a
	fix for that is not coming soon as it is an open investigation area
	if we can fix irq migration to work outside of irq context or if
	we have to rework the requirements imposed by the generic cpu hotplug
	and layer on fixup_irqs().  So this may come up again.
