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]

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:

full feature phase (TARG_CONN_STATE_LOGGED_IN).

TCMU sets TRANSPORT_FLAG_PASSTHROUGH, so INQUIRY commands will not be
emulated by LIO but passed up to userspace. Therefore TCMU should not
set these, just like pscsi doesn't.

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.

Pull PCI fixes from Bjorn Helgaas:
 "Here are a few fixes I'd like to have in v4.4: a generic one for sysfs
  and three for HiSilicon and DesignWare host controllers.

  Summary:

  NUMA:
   - Prevent out of bounds access in numa_node override (Mathias Krause)

  HiSilicon host bridge driver:
   - Fix deferred probing (Arnd Bergmann)

  Synopsys DesignWare host bridge driver:
   - Remove incorrect io_base assignment (Stanimir Varbanov)
   - Move align_resource function pointer to pci_host_bridge structure
     (Gabriele Paoloni)"

* 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.
