Currently, vhost-net and vhost-scsi are sharing the vhost core code.
However, vhost-scsi shares the code by including the vhost.c file
directly.
Making vhost a separate module makes it is easier to share code with
other vhost devices.

vhost_net_ubuf_put_and_wait has a confusing name:
it will actually also free it's argument.
Thus since commit 1280c27f8e29acf4af2da914e80ec27c3dbd5c01
"vhost-net: flush outstanding DMAs on memory change"
vhost_net_flush tries to use the argument after passing it
to vhost_net_ubuf_put_and_wait, this results
in use after free.
To fix, don't free the argument in vhost_net_ubuf_put_and_wait,
add an new API for callers that want to free ubufs.

This patch adds target_get_sess_cmd reference counting for
iscsit_handle_task_mgt_cmd(), and adds a target_put_sess_cmd()
for the failure case.
It also fixes a bug where ISCSI_OP_SCSI_TMFUNC type commands
where leaking iscsi_cmd->i_conn_node and eventually triggering
an OOPs during struct isert_conn shutdown.

This patch moves ISCSI_OP_REJECT failures into iscsit_sequence_cmd()
in order to avoid external iscsit_reject_cmd() reject usage for all
PDU types.
It also updates PDU specific handlers for traditional iscsi-target
code to not reset the session after posting a ISCSI_OP_REJECT during
setup.

target_put_sess_cmd() after iscsit_sequence_cmd() failure)

This patch changes iscsit_add_reject() + iscsit_add_reject_from_cmd()
usage to not sleep on iscsi_cmd->reject_comp to address a free-after-use
usage bug in v3.10 with iser-target code.
It saves ->reject_reason for use within iscsit_build_reject() so the
correct value for both transport cases. It also drops the legacy
fail_conn parameter usage throughput iscsi-target code and adds
two iscsit_add_reject_cmd() and iscsit_reject_cmd helper functions,
along with various small cleanups.
(v2: Re-enable target_put_sess_cmd() to be called from
iscsit_add_reject_from_cmd() for rejects invoked after
target_get_sess_cmd() has been called)

This patch adds the missing isert_put_reject() logic to post
a outgoing payload buffer to hold the 48 bytes of original PDU
header request payload for the rejected cmd.
It also fixes ISTATE_SEND_REJECT handling in isert_response_completion()
-> isert_do_control_comp() code, and drops incorrect iscsi_cmd_t->reject_comp
usage.

* 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.

- sched_clock implementation moved from ARM to core code to avoid

- clocksource and clockevents unregistration facilities
- clocksource/events support for new hardware
- precise nanoseconds RTC readout (Xen feature)
- generic support for Xen suspend/resume oddities
- the usual lot of fixes and cleanups all over the place
The parts which touch other areas (ARM/XEN) have been coordinated with

always return 1 and therefore the subsequent condition will always

Certain older rv770 asics have both a performance and
a 3D performance state rather than just multiple performance
levels in the state power state. The current code would
select the performance state rather than the 3D performance
state when the "performance" profile was selected. This change
switches to the "balanced" profile by default which ends up being
the internal performance profile. When the user selects the
"performance" profile, it selects the internal 3D performance
state so the user can select the higher performance modes.
For most asics this changes nothing. For certain rv770 asics
with static performance and 3D performance states, this allows
you to select between then using by selecting the "balanced"
and "performance" dpm profiles.

then the function simply returns instead of writing to the register.

This patch adds support of connecting an MMC media using an 8-bit
bus width connection to Freescale's P2020 H/W SDHC controller. During
the probe function, the generic function mmc_of_parse is called to
detect whether the controller is configured with 8-bit bus width.
Also, the generic function detects if the non-removable property is
set in the device tree. The function esdhc_pltfm_bus_width was added
because the bus width configuration is platform specific.

The field containing the production date in the CID register only uses
4 bits to encode the year, starting from 1997 in the original standard.
In 2013, the production year field contains 0, and the kernel reports a
1997 production date.
The eMMC 4.51 specification adds a new interpretation rule. For all
devices implementing the 4.41 specification or later, the production
year field will be interpreted as a value between 2010 and 2025, with
