Configuring this option as a module with ACPI_TOSHIBA built-in
results in the following errors:
drivers/built-in.o: In function `toshiba_acpi_remove':
>> toshiba_acpi.c:(.text+0x314bb0): undefined reference to `i8042_remove_filter'
drivers/built-in.o: In function `toshiba_acpi_add':

>> toshiba_acpi.c:(.devinit.text+0xb98b): undefined reference to `i8042_remove_filter'
Add a dependency to prevent ACPI_TOSHIBA from being built-in when
SERIO_I8042=m.

Intel Smart Connect is an Intel-specific ACPI interface for configuring
devices to wake up at regular intervals so they can pull down mail or other
internet updates, and then go to sleep again. If a user enables this in
Windows and then reboots into Linux, the device may wake up if it's put to
sleep. Since there's no Linux userland support for any of this, the machine
will then remain awake until something else puts it back to sleep.
I haven't figured out all that much about how this works (there's a bunch
of different ACPI calls available on the device), but this seems to be
enough to turn it off. We can add more features to this driver if anyone
ever cares about figuring out what the rest of the calls do or writing some
Linux userspace to implement the rest of it.

Intel Rapid Start Technology is a firmware-based suspend-to-disk
implementation. Once placed in S3, the device will wake once either a
timeout elapses or the battery reaches a critical level. It will then resume
to the firmware and copy the contents of RAM to a specialised partition, and
then power off the machine. If the user turns the machine back on the
firmware will copy the contents of the partition back to RAM and then resume
from S3 as normal.
This driver provides an interface for configuring the wakeup events and
timeout. It still requires firmware support and an appropriate suspend
partition.

Controlling the wlan led seems to have some side effects to the machines
with wapf value is not equal to 4. It will make the keyboard backlight
out of order.
So, the patch will enable the wlan led function only if the wapf == 4.

Kyle Evans discovered that he needed to set some bits in an EC register in
order to receive hotkey events. Doing so blindly broke some otherwise
working HP laptops. It turns out that there's a WMI call that accesses
the same register, so let's try calling that instead.

* Fix version recognition in elantech_set_properties
The new hardware reports itself as v7 but the packets'
structure is unaltered.
* Fix packet type recognition in elantech_packet_check_v4
The bitmask used for v6 is too wide, only the last three bits of
the third byte in a packet (packet[3] & 0x03) are actually used to
distinguish between packet types.
Starting from v7, additional information (to be interpreted) is
stored in the remaining bits (packets[3] & 0x1c).
In addition, the value stored in (packet[0] & 0x0c) is no longer
a constant but contains additional information yet to be deciphered.
This change should be backwards compatible with v6 hardware.

In TSG4, register map is 512bytes long and to access all of it,
one bit from address byte is used (which bit to use differs for
I2C and SPI);
Since common code used for TSG3 and TSG4 for I2C, this parameter
wrongly used as u8. TSG3 does not access beyond 255 bytes
but TSG4 may.

The usual straighforward failure to check for dma_mapping_error after a map
operation is completed.
This patch should fix it, the reporter wandered off after filing this bz:
https://bugzilla.redhat.com/show_bug.cgi?id=954170
and I don't have hardware to test, but the fix is pretty straightforward, so I
figured I'd post it for review.

Base on cdc_ether, add the mii functions for RTL8152 and RTL8153.
The RTL8152 and RTL8153 support ECM mode which use the driver of
cdc_ether. Add the mii functions. Then, the basic PHY access is
possible.

We rename the dummy in modprobe.conf like this:
install dummy0 /sbin/modprobe -o dummy0 --ignore-install dummy
install dummy1 /sbin/modprobe -o dummy1 --ignore-install dummy
We got oops when we run the command:
modprobe dummy0
modprobe dummy1

vxlan exit module unregisters vxlan net and then it unregisters
rtnl ops which triggers vxlan_dellink() from __rtnl_kill_links().
vxlan_dellink() deletes vxlan-dev from vxlan_list which has
list-head in vxlan-net-struct but that is already gone due to
net-unregister. That is how we are getting following crash.
Following commit fixes the crash by fixing module exit path.

Userspace may produce vectors greater than MAX_SKB_FRAGS. When we try to
linearize parts of the skb to let the rest of iov to be fit in
the frags, we need count copylen into linear when calling macvtap_alloc_skb()
instead of partly counting it into data_len. Since this breaks
zerocopy_sg_from_iovec() since its inner counter assumes nr_frags should
be zero at beginning. This cause nr_frags to be increased wrongly without
setting the correct frags.
This bug were introduced from b92946e2919134ebe2a4083e4302236295ea2a73
(macvtap: zerocopy: validate vectors before building skb).

Userspace may produce vectors greater than MAX_SKB_FRAGS. When we try to
linearize parts of the skb to let the rest of iov to be fit in
the frags, we need count copylen into linear when calling tun_alloc_skb()
instead of partly counting it into data_len. Since this breaks
zerocopy_sg_from_iovec() since its inner counter assumes nr_frags should
be zero at beginning. This cause nr_frags to be increased wrongly without
setting the correct frags.
This bug were introduced from 0690899b4d4501b3505be069b9a687e68ccbe15b
(tun: experimental zero copy tx support)

According to the commit 16b0dc29c1af9df341428f4c49ada4f626258082
(dummy: fix rcu_sched self-detected stalls)
Eric Dumazet fix the problem in dummy, but the ifb will occur the
same problem like the dummy modules.
Trying to "modprobe ifb numifbs=30000" triggers :
INFO: rcu_sched self-detected stall on CPU
After this splat, RTNL is locked and reboot is needed.
We must call cond_resched() to avoid this, even holding RTNL.

Pull final round of SCSI updates from James Bottomley:
"This is the remaining set of SCSI patches for the merge window. It's
mostly driver updates (scsi_debug, qla2xxx, storvsc, mp3sas). There
are also several bug fixes in fcoe, libfc, and megaraid_sas. We also
have a couple of core changes to try to make device destruction more
deterministic"

A short series of fixes to libfc, libfcoe and fcoe.
Most patches fix formatting problems, one changes
the behavior of which discovered ports can/will be
logged into and another fixes a memory leak.

When repeatedly doing rmmod and modprobe on the ixgbe
driver while FCoE is active in a VN2VN configuration,
memory leaks would be discovered by kmemleak with the
