0045c0dd2f ARM: debug-ll: rework footbridge handling
Footbridge has two debug ports that are handled a bit differently:

The 8250 port uses the normal debug/8250.S implementation that is shared
with a lot of other platforms, but it relies on the DEBUG_UART_8250
option to be turned on automatically instead of being selected by
DEBUG_FOOTBRIDGE_COM1 as we do for most other platforms. I'm changing
this to use a 'select' and change the dependency to the debug symbol
rather than the platform symbol for consistency.

The DC21285 UART has a separate top-level option, and relies on
the traditional include/mach/debug-macro.S method. With the s3c64xx
multiplatform series queued up for 4.5, it is now the last one that does
this, so by moving this file to include/debug/dc21285.S, we can get
all platforms to do things the same way.

59bd4c3827 ARM: debug-ll: rework lpc32xx handling
LPC32xx can not yet be configured in a multiplatform kernel, but
if we ever get there, enabling one of the LPC32xx platforms
while trying to use DEBUG_LL for another platform can default to
the wrong UART address, as the options are purely based on the
architecture being enabled or not.

This changes the logic to use the LPC32xx default addresses only
if we have also picked the respective Kconfig symbols introduced
here.

While we're at it, this also reorders the virtual address as
it should be.

f06455fab6 ARM: debug-ll: rework ep93xx handling
This makes ep93xx debug-ll handling more consistent with the other
platforms, by adding a separate Kconfig symbol for it that
in turn selects the standard DEBUG_UART_PL01X symbol.

We still have to pick a physical address even if DEBUG_LL is disabled
here, because the EP93xx uncompress output code uses
CONFIG_DEBUG_UART_PHYS. If we ever move to multiplatform support,
this can go away.

c047f529e8 ARM: debug-ll: reorganize mvebu debug uart config
As we are moving dove/mv78xx0/orion into multiplatform, the debug-ll
configuration options for these platforms are conflicting with the
multiplatform configuration: enabling one of those platforms sometimes
changes the default addresses to the ones used on one of them, rather
than the one that was selected in Kconfig.

This changes the configuration so we share the physical address
configuration with mach-mvebu.

cdd2e08b21 ARM: debug-ll: fix UART configuration with ARCH_KEYSTONE
We may have multiple platforms enabled and also DEBUG_LL
configured for one of them. However if we enable ARCH_KEYSTONE,
we default to using 32-bit UART access independent of which
platform we are actually using, which can be confusing.

This changes the logic so the 32-bit default gets only
used by default if we actually configure the keystone
UART, as opposed to picking some other 8250 setting on
a kernel that has keystone support enabled.

d94e5a6135 target: fix COMPARE_AND_WRITE non zero SGL offset data corruption
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- lun0 ................ [iblock/ram0 (/dev/ram0)]
      o- lun1 ................ [iblock/ram1 (/dev/ram1)]
% lsscsi -g

[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:

% perl -e 'print chr$_ for 0..255,reverse 0..255' >rand

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.

057085e522 target: Fix race for SCF_COMPARE_AND_WRITE_POST checking
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.

ca82c2bded iscsi-target: Fix rx_login_comp hang after login failure
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).

aa7d5f18e5 ARM: 8454/1: OF implies OF_FLATTREE
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.

c64410f3ec ARM: SoC fixes for 4.4-rc
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

8620015499 xen/evtchn: dynamically grow pending event channel ring
If more than 1024 event channels are bound to a evtchn device then it
possible (even with well behaved applications) for the ring to
overflow and events to be lost (reported as an -EFBIG error).

Dynamically increase the size of the ring so there is always enough
space for all bound events.  Well behaved applicables that only unmask
events after draining them from the ring can thus no longer lose
events.

However, an application could unmask an event before draining it,
allowing multiple entries per port to accumulate in the ring, and a
overflow could still occur.  So the overflow detection and reporting
is retained.

The ring size is initially only 64 entries so the common use case of
an application only binding a few events will use less memory than
before.  The ring size may grow to 512 KiB (enough for all 2^17
possible channels).  This order 7 kmalloc() may fail due to memory
fragmentation, so we fall back to trying vmalloc().

66362c9afc arm64: efi: fix initcall return values
Even though initcall return values are typically ignored, the
prototype is to return 0 on success or a negative errno value on
error. So fix the arm_enable_runtime_services() implementation to
return 0 on conditions that are not in fact errors, and return a
meaningful error code otherwise.

Add NULL return value checks to two invocations of early_memremap()
in the UEFI init code. For the UEFI configuration tables, we just
warn since we have a better chance of being able to report the issue
in a way that can actually be noticed by a human operator if we don't
abort right away. For the UEFI memory map, however, all we can do is
panic() since we cannot proceed without a description of memory.
