This is needed for determining the reason for failure when a softdog
timeout occurs.
We use softdog to watch for critical application failures and at the
minimum a snapshot of the system would help to determine the cause. In
such a scenario the application could fail but there isn't a softlockup as
such, hence the detect softlockup feature does not help.
The patch adds a module parameter soft_panic which when set to 1 causes
softdog to invoke panic instead of reboot when the softdog timer expires.
By invoking panic we execute kdump if it is configured and the vmcore
generated by kdump should provide atleast a minimal idea of the reason for
failure.

While testing the performance of different receive interrupt
coalescing settings on a single stream TCP benchmark, I noticed two
very different results. With rx-usecs=50, most of the time a
connection would hit 8280 Mbps but once in a while it would hit
9330 Mbps.
It turns out we are only applying the interrupt coalescing settings
to the first queue and whenever the rx hash would direct us onto
that queue we ran faster.
With this patch applied and rx-usecs=50, I get 9330 Mbps
consistently.

In commit 95a0f10cdd ("drbd: store in-core bitmap little endian,
regardless of architecture") drbd had made the sane choice to use
little-endian bitmap functions everywhere. However, it used the
horrible old functions names from <asm-generic/bitops/le.h>, that were
never really meant to be exported.
In the meantime, things got cleaned up, and in commit c4945b9ed4
("asm-generic: rename generic little-endian bitops functions") we
renamed the LE bitops to something sane, exactly so that they could be
used in random code without people gouging their eyes out when seeing
the crazy jumble of letters that were the old internal names.
As a result the drbd thing merged cleanly (commit 8d49a77568: "Merge
branch 'for-2.6.39/drivers' of git://git.kernel.dk/linux-2.6-block"),
since there was no data conflict - but the end result obviously doesn't

Acer WMI hotkey event's result include current device status, just
need sync the status to killswitch after acer-wmi driver receive
hotkey event but not always poll device status. This is good for
performance.
But, if use EC raw mode, Acer BIOS will not emit wmi event and
leave EC to control device status. So, still startup polling job
when doesn't detect WMI event GUID or user choice to use ec_raw_mode.

Acer BIOS keeps devices state when system reboot, but reset to default
device states (Wlan on, Bluetooth off, wwan on) if system cold boot.
That means BIOS's initial state is not always real persistence.
So, removed rfkill_init_sw_state because it sets initial state to
persistence then replicate to other new killswitch when rfkill-input
enabled.
After removed it, acer-wmi set initial soft-block state after rfkill
register, and doesn't allow set_block until rfkill initial finished.
