The conversion is quite complex given that the libata new error
handler has to be hooked into the current libsas timeout and error
handling. The way this is done is to process all the failed commands
via libsas first, but if they have no underlying sas task (and they're
on a sata device) assume they are destined for the libata error
handler and send them accordingly.
Finally, activate the port recovery of the libata error handler for
each port known to the host. This is somewhat suboptimal, since that
port may not need recovering, but given the current architecture of
the libata error handler, it's the only way; and the spurious
activation is harmless.

Right at the moment, the libata error handler is incredibly
monolithic. This makes it impossible to use from composite drivers
like libsas and ipr which have to handle error themselves in the first
instance.
The essence of the change is to split the monolithic error handler
into two components: one which handles a queue of ata commands for
processing and the other which handles the back end of readying a
port. This allows the upper error handler fine grained control in
calling libsas functions (and making sure they only get called for ATA
commands whose lower errors have been fixed up).

The SCSI host eh_cmd_q should be protected by the host lock (not the
port lock). This probably doesn't matter that much at the moment,
since we try to serialise the add and eh pieces, but it might matter
in future for more convenient error handling. Plus this switches
libata to the standard eh pattern where you lock, remove from the cmd
queue to a local list and unlock and then operate on the local list.

For historical reasons, libsas uses the scsi host lock as the ata port
lock, and libata always uses the ata host. For the old eh, this was
largely irrelevant since the two locks were never mixed inside the
code. However, the new eh has a case where it nests acquisition of
the host lock inside the port lock (this does look rather deadlock
prone). Obviously this would be an instant deadlock if the port lock
were the host lock, so switch the libsas paths to use the ata host
lock as well.

The function ata_sas_port_init() has always really done its own thing.
However, as a precursor to moving to the libata new eh, it has to be
properly using the standard libata scan paths. This means separating
the current libata scan paths into pieces which can be shared with
libsas and pieces which cant (really just the async call and the host
scan).

ata_eh_analyze_serror() suppresses hotplug notifications if LPM is
being used because LPM generates spurious hotplug events. It compared
whether link->lpm_policy was different from ATA_LPM_MAX_POWER to
determine whether LPM is enabled; however, this is incorrect as for
drivers which don't implement LPM, lpm_policy is always
ATA_LPM_UNKNOWN. This disabled hotplug detection for all drivers
which don't implement LPM.
Fix it by comparing whether lpm_policy is greater than
ATA_LPM_MAX_POWER.

Several ACPI drivers fail to build if CONFIG_NET is unset, because
they refer to things depending on CONFIG_THERMAL that in turn depends
on CONFIG_NET. However, CONFIG_THERMAL doesn't really need to depend
on CONFIG_NET, because the only part of it requiring CONFIG_NET is
the netlink interface in thermal_sys.c.
Put the netlink interface in thermal_sys.c under #ifdef CONFIG_NET
and remove the dependency of CONFIG_THERMAL on CONFIG_NET from
drivers/thermal/Kconfig.

Somehow fixes a misrendering + hang at GDM startup on my NVA8...
My first guess would have been stale TLB entries laying around that a new
bo then accidentally inherits. That doesn't make a great deal of sense
however, as when we mapped the pages for the new bo the TLBs would've
gotten flushed anyway.

CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base.
The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power
domain control register
Fix the same.
The autogen scripts is fixed thanks to Benoit Cousson
With the old value, the clockdomain code would access the
*_PWRSTCTRL.POWERSTATE field when it thought it was accessing the
*_CLKSTCTRL.CLKTRCTRL field. In the worst case, this could cause
system power management to behave incorrectly.

In OMAP35X TRM Rev 2010-05 Figure 7-18 "DPLL With EMI Reduction
Feature", it is shown that the internal frequency is calculated by
CLK_IN/(N+1). However, the value passed to _dpll_test_fint() is
already "N+1" since Linux is using the values to divide by. In the
technical reference manual, "N" is referring to the divider's register
value (0-127).
During power management testing, it was observed that programming the
wrong jitter correction value can cause the system to become unstable
and eventually crash.

Without CONFIG_OMAP_32K_TIMER, the kernel has an clockevent and
clocksource resolution about three orders of magnitude higher than

power consumption states are not available.
Fix by calling init_sched_clock() from the GPTIMER clocksource init code.

When the per cpu timer is marked CLOCK_EVT_FEAT_C3STOP, then we only
can switch into oneshot mode, when the backup broadcast device
supports oneshot mode as well. Otherwise we would try to switch the
broadcast device into an unsupported mode unconditionally. This went
unnoticed so far as the current available broadcast devices support
oneshot mode. Seth unearthed this problem while debugging and working
around an hpet related BIOS wreckage.
Add the necessary check to tick_is_oneshot_available().

They noticed when only 4 bytes were set to 0 instead of 8,
everything worked correctly.

| We're supposed to be resetting trampoline_phys_low and
| trampoline_phys_high here, which are two 16-bit values.

Currently numcpus is determined in pid_put_sample which is only

On a machine with a lot cpus I often saw the last cpu missing.
Check for (max) numcpus on every event happening and in the
beginning. -> fixes the issue for me.

fuse: fix truncate after open
fuse: fix hang of single threaded fuseblk filesystem

Commit e1181ee6 "vfs: pass struct file to do_truncate on O_TRUNC
opens" broke the behavior of open(O_TRUNC|O_RDONLY) in fuse. Fuse
assumed that when called from open, a truncate() will be done, not an
ftruncate().
Fix by restoring the old behavior, based on the ATTR_OPEN flag.

Single threaded NTFS-3G could get stuck if a delayed RELEASE reply
triggered a DESTROY request via path_put().
Fix this by
a) making RELEASE requests synchronous, whenever possible, on fuseblk
filesystems
b) if not possible (triggered by an asynchronous read/write) then do
the path_put() in a separate thread with schedule_work().

Commit 2c442719e90a44a6982c033d69df4aae4b167cfa added some checks for proper
heartbeat mode when the o2cb stack is running. Unfortunately, it didn't
take into account that a userpsace stack could be running. Fix this by only
doing the check if o2cb is in use. This patch allows userspace stacks to
mount the fs again.

right number.
Current refcounttree codes actually didn't writeback the new pages out in
write-back mode, due to a bug of always passing a ZERO number of clusters
to 'ocfs2_cow_sync_writeback', the patch tries to pass a proper one in.

The microphone detection functionality requires a clock to work. In any
non-detection case where the MICBIAS is enabled CLK_SYS will be needed
anyway so there is no negative impact on power consumption.

When a USB audio device is disconnected, snd_usb_audio_disconnect()
kills all audio URBs. At the same time, the application, after being
notified of the disconnection, might close the device, in which case
ALSA calls the .hw_free callback, which should free the URBs too.
Commit de1b8b93a0ba "[ALSA] Fix hang-up at disconnection of usb-audio"
prevented snd_usb_hw_free() from freeing the URBs to avoid a hang that
resulted from this race, but this introduced another race because the
URB callbacks could now be executed after snd_usb_hw_free() has
returned, and try to access already freed data.
Fix the first race by introducing a mutex to serialize the disconnect
callback and all PCM callbacks that manage URBs (hw_free and hw_params).
