For platform with auto restart support, between every transfer,
i2c controller will trigger an interrupt and SW need to handle
it to start new transfer. When doing write-then-read transfer,
instead of restart mechanism, using WRRD mode to have controller
send both transfer in one request to reduce latency.

This patch adds support for port names for the SB800 chipset.

The SB800 chipset supports a multiplexed main SMBus controller with
four ports. The multiplexed ports share the same SMBus address and
register set. The port is selected by bits 2:1 of the smb_en register
(0x2C).
Only one port can be active at any point in time therefore a mutex is
needed in order to synchronize access.
Additionally, the commit avoids requesting and releasing the SMBus base
address index region on every multiplexed transfer by moving the
request_region call into piix4_probe.
Tested on HP ProLiant MicroServer G7 N54L (where this patch adds
support to access sensor data from the w83795adg).

If we don't clear START generation as soon as possible, it may cause
another message to be generated, e.g. when receiving NACK in address
phase. To keep the race window as small as possible, we clear it right
at the beginning of the interrupt. We don't need any checks since we
always want to stop START and STOP generation on the next occasion after
we started it.
This patch improves the situation but sadly does not completely fix it.
It is still to be researched if we can do better given this HW design.

Setting up new messages was done in process context while handling a

is sensitive to timing, so the context switches were too expensive. Move
this setup to interrupt context as well.
In my test setup, this fixed the occasional 'data byte sent twice' issue

This patch addresses a race + use after free where the first
stage of COMPARE_AND_WRITE in compare_and_write_callback()
is rescheduled after the backend sends the secondary WRITE,
resulting in second stage compare_and_write_post() callback
completing in target_complete_ok_work() before the first
can return.
Because current code depends on checking se_cmd->se_cmd_flags
after return from se_cmd->transport_complete_callback(),
this results in first stage having SCF_COMPARE_AND_WRITE_POST
set, which incorrectly falls through into second stage CAW
processing code, eventually triggering a NULL pointer
dereference due to use after free.
To address this bug, pass in a new *post_ret parameter into
se_cmd->transport_complete_callback(), and depend upon this
value instead of ->se_cmd_flags to determine when to return
or fall through into ->queue_status() code for CAW.

On the ARM architecture, individual platforms select CONFIG_USE_OF if they
need it, but all device tree code is keyed off CONFIG_OF. When building
a platform without DT support and manually enabling CONFIG_OF, we now
get a number of build errors, e.g.
arch/arm/kernel/devtree.c: In function 'setup_machine_fdt':
arch/arm/kernel/devtree.c:215:19: error: implicit declaration of function 'early_init_dt_verify' [-Werror=implicit-function-declaration]
We could now try to separate the use case of booting from DT vs. the
case of using the dynamic implementation, but that seems more complicated
than it can gain us.
This simply changes the ARM Kconfig file to always enable OF_RESERVED_MEM
and OF_EARLY_FLATTREE when CONFIG_OF is enabled. These options add a little
extra code when we just want the dynamic OF implementation, but that seems
like a rather obscure case, and this version solves all CONFIG_OF related
randconfig regressions.

Merge tag 'nfs-for-4.4-2' of git://git.linux-nfs.org/projects/trondmy/linux-nfs
Pull NFS client bugfixes from Trond Myklebust:
"Highlights include:
Stable patches:
- Fix a NFSv4 callback identifier leak that was also causing client
crashes
- Fix NFSv4 callback decoding issues when incoming requests are
truncated
- Don't declare the attribute cache valid when we call
nfs_update_inode with an empty attribute structure.
- Resend LAYOUTGET when there is a race that changes the seqid
Bugfixes:
- Fix a number of issues with the NFSv4.2 CLONE ioctl()
- Properly set NFS v4.2 NFSDBG_FACILITY
- NFSv4 referrals are broken; Cleanup FATTR4_WORD0_FS_LOCATIONS after
decoding success
- Use sliding delay when LAYOUTGET gets NFS4ERR_DELAY
- Ensure that attrcache is revalidated after a SETATTR"

There is a small backlog of at91 patches here, the most significant is
the addition of some sama5d2 Xplained nodes that were waiting on an MFD include
file to get merged through another tree. We normally try to sort those out
before the merge window opens, but the maintainer wasn't aware of that here
and I decided to merge the changes this time as an exception.
On OMAP a series of audio changes for dra7 missed the merge window but turned
out to be necessary to fix a boot time imprecise external abort error and to
get audio working.
The other changes are the usual simple changes, here is a list sorted by
platform:
at91:
removal of a useless defconfig option
removal of some legacy DT pieces
use of the proper watchdog compatible string
update of the MAINTAINERS entries for some Atmel drivers
drivers/scpi:
hide get_scpi_ops in module from built-in code
imx:
add missing .irq_set_type for i.MX GPC irq_chip.
fix the wrong spi-num-chipselects settings for Vybrid DSPI devices.
fix a merge error in Vybrid dts regarding to ADC device property
keystone:
fix the optional PDSP firmware loading
fix linking RAM setup for QMs
fix crash with clk_ignore_unused
mediatek:
