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 bkl

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
/<debugfs mountpoint>/qdio/<device bus ID>/statistics enables the
statistics for the given device.

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.

firewire, ieee1394: update Kconfig help

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 listeners
Comments 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:

After commit b9c3b266411d27f1a6466c19d146d08db576bfea ("PCI: support
device-specific reset methods") the kernel build is broken if
CONFIG_PCI_QUIRKS is unset.
Fix this by moving pci_dev_specific_reset() to drivers/pci/quirks.c and

with CONFIG_GART_IOMMU enabled drivers/char/agp/amd64-agp.c has:
#ifndef CONFIG_GART_IOMMU
module_init(agp_amd64_init);
module_exit(agp_amd64_cleanup);
#endif
agp_amd64_init() was called via gart_iommu_init with
CONFIG_GART_IOMMU=y agp_amd64_init() was called via module_init
with CONFIG_GART_IOMMU=n
The 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).

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).

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

Today's -tip failed to build because commit
9e368fa011d4e0aa050db348d69514900520e40b ("ipmi: add PNP discovery (ACPI
namespace via PNPACPI)") from today's upstream kernel causes the following
build failure on x86, for CONFIG_ACPI=n && CONFIG_IPMI_SI=y:
drivers/char/ipmi/ipmi_si_intf.c:3208: error: 'ipmi_pnp_driver' undeclared (first use in this function)
drivers/char/ipmi/ipmi_si_intf.c:3208: error: (Each undeclared identifier is reported only once

drivers/char/ipmi/ipmi_si_intf.c:3334: error: 'ipmi_pnp_driver' undeclared (first use in this function)
The reason is that the ipmi_pnp_driver depends on ACPI facilities and is only
made available under ACPI - while the registration and unregistration is made
dependent on CONFIG_PNP:
#ifdef CONFIG_PNP
pnp_register_driver(&ipmi_pnp_driver);
#endif
The solution is to only register this driver under ACPI. (Also, the CONFIG_PNP
dependency is not needed because pnp_register_driver() is stubbed out in the
!CONFIG_PNP case.)

If two arrays share a device, then they will not both resync at the
same time. One will wait for the other to complete.
While waiting, the MD_RECOVERY_INTR flag is not checked so a device
failure, which would make the resync pointless, does not cause the
resync to abort, so the failed device cannot be removed (as it cannot
be remove while a resync is happening).
So add a test for MD_RECOVERY_INTR.

Since commit dfc7064500061677720fa26352963c772d3ebe6b,
->hot_remove_disks has not removed non-failed devices from
an array until recovery is no longer possible.
So the code in do_md_run to get around the fact that
md_check_recovery (which calls ->hot_remove_disks) would
remove partially-in-sync devices is no longer needed.
So remove it.

By default md_do_sync() will perform recovery if no other actions are
specified. However, action_show() relies on MD_RECOVERY_RECOVER to be

MD_RECOVERY_RECOVER when starting recovery.

The start_ro modules parameter can be used to force arrays to be
started in 'auto-readonly' in which they are read-only until the first
write. This ensures that no resync/recovery happens until something
else writes to the device. This is important for resume-from-disk
off an md array.
However if an array is started 'readonly' (by writing 'readonly' to
the 'array_state' sysfs attribute) we want it to be really 'readonly',
not 'auto-readonly'.
So strengthen the condition to only set auto-readonly if the
array is not already read-only.

evms configures md arrays by:
open device
send ioctl
close device
for each different ioctl needed.
Since 2.6.29, the device can disappear after the 'close'
unless a significant configuration has happened to the device.
The change made by "SET_ARRAY_INFO" can too minor to stop the device
from disappearing, but important enough that losing the change is bad.
So: make sure SET_ARRAY_INFO sets mddev->ctime, and keep the device
active as long as ctime is non-zero (it gets zeroed with lots of other
things when the array is stopped).
This is suitable for -stable kernels since 2.6.29.
