fc97114b8d sh: Fix boot crash related to SCI
Commit d006199e72a9 ("serial: sh-sci: Regtype probing doesn't need to be
fatal.") made sci_init_single() return when sci_probe_regmap() succeeds,
although it should return when sci_probe_regmap() fails.  This causes
systems using the serial sh-sci driver to crash during boot.

Fix the problem by using the right return condition.

6e5714eaf7 net: Compute protocol sequence numbers and fragment IDs using MD5.
Computers have become a lot faster since we compromised on the
partial MD4 hash which we use currently for performance reasons.

MD5 is a much safer choice, and is inline with both RFC1948 and
other ISS generators (OpenBSD, Solaris, etc.)

Furthermore, only having 24-bits of the sequence number be truly
unpredictable is a very serious limitation.  So the periodic
regeneration and 8-bit counter have been removed.  We compute and
use a full 32-bit sequence number.

For ipv6, DCCP was found to use a 32-bit truncated initial sequence
number (it needs 43-bits) and that is fixed here as well.

4b00e4b394 savagedb: Fix typo causing regression in savage4 series video chip detection
Two additional savage4 variants were added, but the S3_SAVAGE4_SERIES
macro was incompletely modified, resulting in a false positive detection
of a savage4 card regardless of which savage card is actually present.

For non-savage4 series cards, such as a Savage/IX-MV card, this results
in garbled video and/or a hard-hang at boot time.  Fix this by changing
an '||' to an '&&' in the S3_SAVAGE4_SERIES macro.

This patch introduces separate lock to struct acpi_battery to

So fix by Lan Tianyu is still there, we just grab independent lock.

02b26774af PM / Runtime: Allow _put_sync() from interrupts-disabled context
Currently the use of pm_runtime_put_sync() is not safe from
interrupts-disabled context because rpm_idle() will release the
spinlock and enable interrupts for the idle callbacks.  This enables
interrupts during a time where interrupts were expected to be
disabled, and can have strange side effects on drivers that expected
interrupts to be disabled.

This is not a bug since the documentation clearly states that only
_put_sync_suspend() is safe in IRQ-safe mode.

However, pm_runtime_put_sync() could be made safe when in IRQ-safe
mode by releasing the spinlock but not re-enabling interrupts, which
is what this patch aims to do.

Problem was found when using some buggy drivers that set
pm_runtime_irq_safe() and used _put_sync() in interrupts-disabled
context.

6ae8b80737 eeepc-wmi: Add support for T101MT Home/Express Gate key
This key is different than other hotkeys, having seperate scan
codes for press, release, and hold, so it requires some special
filtering. Press and release events are passed on, and hold events
are ignored since sparse-keymap does not support hardware
autorepeat.

Note that "Home" in the context of this button doesn't mean the
same thing as the usual Home key, and it really isn't clear at
all what is meant by "Home". The manufacurer's description of the
button indicates that it should launch some sort of touch screen
settings interface on short press and apply a desktop rotation on
long press.

49979d091d asus-wmi: fix hwmon/pwm1
The code was completly broken, and should never had been sent
to the kernel. That's what happens when you write code without
hardware to test it.

b06862ba6b acerhdf: add support for Aspire 1810TZ BIOS v1.3314
Would you please consider applying the following patch adding support for
the Aspire 1810TZ BIOS v.1.3314 version to the acerhdf module and avoids the
following error:

acerhdf: unknown (unsupported) BIOS version Acer/Aspire 1810TZ/v1.3314, ple=
ase report, aborting!

Not sure about the other Aspire models, but it seems at least 1810T should
also be updated.

7b8aca65db acer-wmi: schedule threeg and interface sysfs for feature removal
we can now autodetect internal 3G device and already have the threeg
rfkill device. So, we plan to remove threeg sysfs support for it's no
longer necessary.

We also plan to remove interface sysfs file that exposed which ACPI-WMI
interface that was used by acer-wmi driver. It will replaced by information
log when acer-wmi initial.

We keep it around for userspace compatibility reasons, schedule removal
in 2012.
