In bbc_envctrl_init() we have to unlink the fan and temp instances
from the lists because our caller is going to free up the 'bp' object
if we return an error.We can't rely upon bbc_envctrl_cleanup() to do this work for us in
this case.Reported-by: Patrick Finnegan

The BKL is in this function because of the BKL pushdown (see commit
f8f2c79d594463427f7114cedb1555110d547d89)It is not needed here because the mutex_lock sonypi_device.lock provides
the necessary locking.sonypi_misc_ioctl can be converted to unlocked ioctls since it relies on
its own locking (the mutex sonypi_device.lock) and not the bklDocument that llseek is not needed by explictly setting it to no_llseek

Revamp the qdio performance statistics and move them from procfs to
debugfs using the seq_file interface. Since the statistics are not
intended for the general user the removal of /proc/qdio_perf should
not surprise anyone.The per device statistics are disabled by default, writing 1 to
//qdio//statistics enables the
statistics for the given device.Signed-off-by: Jan Glauber

Commit 239007b844 ("genirq: Convert irq_desc.lock to raw_spinlock")
seems to have missed this driver, leaving it to use the normal spin-lock
functions for the irq descriptor lock, which is now a raw lock.Reported-and-compile-tested-by: Stephen Rothwell

Introduced by commit 5b889bf23 ("PCI: Fix build if quirks are not
enabled"), which made the pci_dev_reset_methods[] array static and
'const', but didn't then change the code to match, and use a const
pointer when moving it to quirks.c.Trivially fixed by just adding the required 'const' to the iterator
variable.Reported-by: Stephen Rothwell

firewire: ohci: always use packet-per-buffer mode for isochronous reception
firewire: cdev: fix another memory leak in an error path
firewire: fix use of multiple AV/C devices, allow multiple FCP listenersComments from Stefan:
Distributors who still ship the old stack (ieee1394, ohci1394,
raw1394, sbp2, eth1394 and more) should now switch to the new one
(firewire-core, firewire-ohci, firewire-sbp2, firewire-net). In the
first iteration, those distributors might want to ship the old stack
also (but blacklisted) as a fallback for their users if unforeseen
problems with the newer replacement drivers are encountered.The older FireWire stack contains several known problems which are
not going to be fixed; instead, those issues are addressed by the new
stack. An incomplete list of these issues is kept in bugzilla:http://bugzilla.kernel.org/show_bug.cgi?id=10046
We have a guide on migration from the older to the newer stack:

#endifagp_amd64_init() was called via gart_iommu_init with

with CONFIG_GART_IOMMU=nThe commit 75f1cdf1dda92cae037ec848ae63690d91913eac changes the
x86 dma initialization routine: gart_iommu_init() is called only
when GART IOMMU is detected. So when GART IOMMU isn't detected,
agp_amd64_init isn't called.Marin Mitov reported this issue:
http://marc.info/?l=linux-kernel&m=126192729110083&w=2
With this patch, agp_amd64_init() is always called via
module_init (the above ifndef is removed). If agp_amd64_init()
is called via gart_iommu_init() earlier, agp_amd64_init()
finishes without doing anything (when it is called via
module_init).Reported-by: Marin Mitov

It would appear that in BIOS's with nVidia hooks, the GUID
05901221-D566-11D1-B2F0-00A0C9062910 is duplicated. For now, the simplest
solution is to just ignore any duplicate GUIDs. These particular hooks are not
currently supported/ used in the kernel, so whoever does that can figure out
what the 'right' solution should be (if there's a better one).http://bugzilla.kernel.org/show_bug.cgi?id=14846

When acpi_evaluate_object() is passed ACPI_ALLOCATE_BUFFER,
the caller must kfree the returned buffer if AE_OK is returned.The callers of wmi_get_event_data() pass ACPI_ALLOCATE_BUFFER,

Emphasize that that wmi_install_notify_handler() returns an acpi_status
