Implement ata_scsi_unlock_native_capacity() which will be called
through SCSI layer when block layer notices that partitions on a
device extend beyond the end of the device. It requests EH to unlock
HPA, waits for completion and returns the current device capacity.
This allows libata to unlock HPA on demand instead of having to decide
whether to unlock upfront. Unlocking on demand is safer than
unlocking by upfront because some BIOSes write private data to the
area beyond HPA limit. This was suggested by Ben Hutchings.

Per IEEE 1394 clause 8.4.2.3, a contender for the IRM role shall check
whether the current IRM complies to 1394a-2000 or later. If not force a
compliant node (e.g. itself) to become IRM. This was implemented in the
older ieee1394 driver but not yet in firewire-core.
An older Sony camcorder (Sony DCR-TRV25) which implements 1394-1995 IRM
but neither 1394a-2000 IRM nor BM was now found to cause an
interoperability bug:
- Camcorder becomes root node when plugged in, hence gets IRM role.
- firewire-core successfully contends for BM role, proceeds to perform
gap count optimization and resets the bus.
- Sony camcorder ignores presence of a BM (against the spec, this is
a firmware bug), performs its idea of gap count optimization and
resets the bus.
- Preceding two steps are repeated endlessly, bus never settles,
regular I/O is practically impossible.
http://thread.gmane.org/gmane.linux.kernel.firewire.user/3913
This is an interoperability regression from the old to the new drivers.
Fix it indirectly by adding the 1394a IRM check. The spec suggests
three and a half methods to determine 1394a compliance of a remote IRM;
we choose the method of testing the Config_ROM.Bus_Info.generation
field. This is data that firewire-core should have readily available at
this point, i.e. does not require extra I/O.

By calling korina_restart(), the IRQ handler tries to disable the
interrupt it's currently serving. This leads to a deadlock since
disable_irq() waits for any running IRQ handlers to finish before
returning. This patch addresses the issue by turning korina_restart()
into a workqueue task, which is then scheduled when needed.
Reproducing the deadlock is easily done using e.g. GNU netcat to send
large amounts of UDP data to the host running this driver.
Note that the same problem (and fix) applies to TX FIFO underruns, but
apparently these are less easy to trigger.

Since commit 98962465ed ("nohz: Prevent

the clocksource is registered. As a consequence the safe maximum sleep
time is negative and the CPU never goes into idle.

Grant patches added an of mach table to struct device_driver. However,
while he changed the macio device code to use that, he left the match
table pointer in struct macio_driver and didn't update drivers to use
the "new" one, thus breaking the probing.
This completes the change by moving all drivers to setup the "new"

changes the exact same locations), I also remove two other duplicates

This adds a wrapper to do so, and uses it appropriately.

Note that because we cannot easily determine which socket will be

IR support on FusionHDTV cards is broken since kernel 2.6.31. One side
effect of the switch to the standard binding model for IR I2C devices
was to let i2c-core do the probing instead of the ir-kbd-i2c driver.
There is a slight difference between the two probe methods: i2c-core
uses 0-byte writes, while the ir-kbd-i2c was using 0-byte reads. As
some IR I2C devices only support reads, the new probe method fails to
detect them.
For now, revert to letting the driver do the probe, using 0-byte
reads. In the future, i2c-core will be extended to let callers of
i2c_new_probed_device() provide a custom probing function.

pvrusb2: Delete sysfs class device as the _very_ last step, after
we're sure that all driver contexts have gone away first. This is
important because it appears that there isn't any protection from a
struct device instance reference a deleted struct class instance. The
assumption in the kernel code appears to be that the class instance is
assumed to be around for the life of the device. So we can't let the
class instance go away until all referencing device instances are
gone; this is ensured by delaying removal of the class instance until
after the driver contexts have all gone away. This bug has been
present for a very long time but it didn't apparently become malignant
until recently (probably because of other changes in the kernel).

Add a spin_unlock missing on the error path. The return value of write_reg
seems to be completely ignored, so it seems that the lock should be

This patch fixes an occasional transmit lockup in the mac-fcc which
occurs after a tx error. The test scenario had the local port set
to autoneg and the other end fixed at 100FD, resulting in a large
number of late collisions.
According to the MPC8280RM 30.10.1.3 (also 8272RM 29.10.1.3), after
a tx error occurs, TBPTR may sometimes point beyond BDs still marked
as ready. This patch walks back through the BDs and points TBPTR to
the earliest one marked as ready.
Tested on a custom board with a MPC8280.

There still is a race that may result in suspending the system in
the middle of an EC transaction in progress, which leads to problems
(like the kernel thinking that the ACPI global lock is held during
resume while in fact it's not).
To remove the race condition, modify the ACPI platform suspend and
hibernate callbacks so that EC transactions are blocked right after
executing the _PTS global control method and are allowed to happen
again right after the low-level wakeup.
Introduce acpi_pm_freeze() that will disable GPEs, wait until the
event queues are empty and block EC transactions. Use it wherever
GPEs are disabled in preparation for switching local interrupts off.
Introduce acpi_pm_thaw() that will allow EC transactions to happen
again and enable runtime GPEs. Use it to balance acpi_pm_freeze()
wherever necessary.
In addition to that use acpi_ec_resume_transactions_early() to
unblock EC transactions as early as reasonably possible during
resume. Also unblock EC transactions in acpi_hibernation_finish()
and in the analogous suspend routine to make sure that the EC
transactions are enabled in all error paths.

acpi pad driver kind of aggressively marks TSC as unstable at init
time, on mwait capable and non X86_FEATURE_NONSTOP_TSC systems. This is
irrespective of whether pad driver is ever going to be used on the
system or deep C-states are supported/used. This will affect every user
who just happens to compile in (or get a kernel version which
compiles in) acpi pad driver.
Move mark_tsc_unstable() out of init to the actual idle invocation path
of the pad driver.
There is also another bug/missing_feature in the code that it does not
support 'always running apic timer' and switches to broadcast mode
unconditionally. Shaohua, can you take a look at that please.

This EXPERIMENTAL driver supersedes acpi_idle on
Intel Atom Processors, Intel Core i3/i5/i7 Processors
and associated Intel Xeon processors.
It does not support the Intel Core2 processor or earlier.
For kernels configured with ACPI, CONFIG_INTEL_IDLE=y
allows intel_idle to probe before the ACPI processor driver.
Booting with "intel_idle.max_cstate=0" disables intel_idle
and the system will fall back on ACPI's "acpi_idle".
Typical Linux distributions load ACPI processor module early,
making CONFIG_INTEL_IDLE=m not easily useful on ACPI platforms.
intel_idle probes all processors at module_init time.
Processors that are hot-added later will be limited
to using C1 in idle.

commit d306ebc286
(ACPI: Be in TS_POLLING state during mwait based C-state entry)
fixed an important power & performance issue where ACPI c2 and c3 C-states
were clearing TS_POLLING even when using MWAIT (ACPI_STATE_FFH).
That bug had been causing us to receive redundant scheduling interrups
when we had already been woken up by MONITOR/MWAIT.
Following up on that...
In the MWAIT case, we don't have to subsequently
check need_resched(), as that c heck was there
for the TS_POLLING-clearing case.
Note that not only does the cpuidle calling function
already check need_resched() before calling us, the
low-level entry into monitor/mwait calls it twice --
guaranteeing that a write to the trigger address
can not go un-noticed.
Also, in this case, we don't have to set TS_POLLING
when we wake, because we never cleared it.
