Samsung DeviceTree ARM64 updates and improvements for 4.5:
1. Add S2MPS15 PMIC node to Espresso board. This gives proper
   control over regulators, provides 32KHz clocks and RTC driver.
2. Enable HS200 mode operation on Espresso board for MMC0.
3. Add reboot capability (generic syscon-reboot).

target_core_sbc's compare_and_write functionality suffers from taking
data at the wrong memory location when writing a CAW request to disk
when a SGL offset is non-zero.

This can happen with loopback and vhost-scsi fabric drivers when
SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC is used to map existing user-space
SGL memory into COMPARE_AND_WRITE READ/WRITE payload buffers.

Given the following sample LIO subtopology,

% targetcli ls /loopback/
o- loopback ................................. [1 Target]
  o- naa.6001405ebb8df14a ....... [naa.60014059143ed2b3]
    o- luns ................................... [2 LUNs]
      o- lun0 ................ [iblock/ram0 (/dev/ram0)]

[3:0:1:1]    disk    LIO-ORG  IBLOCK           4.0   /dev/sdd   /dev/sg4

the following bug can be observed in Linux 4.3 and 4.4~rc1:

Rather than writing all-zeroes as instructed with the -D file, it
corrupts the data in the sector by splicing some of the original
bytes in. The page of the first entry of cmd->t_data_sg includes the
CDB, and sg->offset is set to a position past the CDB. I presume that
sg->offset is also the right choice to use for subsequent sglist
members.

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.

This patch addresses a case where iscsi_target_do_tx_login_io()
fails sending the last login response PDU, after the RX/TX
threads have already been started.

The case centers around iscsi_target_rx_thread() not invoking
allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs
from the failure path, resulting in RX thread hanging
indefinately on iscsi_conn->rx_login_comp.

Note this bug is a regression introduced by:

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.

* tag 'pci-v4.4-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci:
  ARM/PCI: Move align_resource function pointer to pci_host_bridge structure
  PCI: hisi: Fix deferred probing
  PCI: designware: Remove incorrect io_base assignment
  PCI: Prevent out of bounds access in numa_node override

The firmware can support PSCI-1.0 in fact. This change also enables
suspend to ram on Marvell berlin arm64 SoC.

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"

Pull ARM SoC fixes from Arnd Bergmann:
 "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:
	Enable SCPSYS power domain driver by default

  mvebu:
	fix QNAP TS219 power-off in dts
	fix legacy get_irqnr_and_base for dove and orion5x

  omap:
	fix l4 related boot time errors for dm81xx
	use lockless cldm/pwrdm api in omap4_boot_secondary
	remove t410 abort handler to avoid hiding other critical errors
	mark cpuidle tracepoints as _rcuidle
	fix module alias for omap-ocp2scp

  pxa:
	palm: Fix typos in PWM lookup table code

  renesas:
	missing __initconst annotation for r8a7793_boards_compat_dt

  rockchip:
	disable mmc-tuning on the veyron-minnie board
	adding the init state for the over-temperature-protection

  zx:
	only build power domain code when CONFIG_PM=y"
