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).

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.

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.

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"

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().

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.

After commit 8c058b0b9c ("x86/irq: Probe for PIC presence before
allocating descs for legacy IRQs") early_irq_init() will no longer
preallocate descriptors for legacy interrupts if PIC does not
exist, which is the case for Xen PV guests.
Therefore we may need to allocate those descriptors ourselves.

The cpuid_feature_extract_field() extracts the feature value
as a signed integer. This could be problematic for features
whose values are unsigned. e.g, ID_AA64DFR0_EL1:BRPs. Add
an unsigned variant for the unsigned fields.

Doing so will cause the grant to be unmapped and then, during
fault handling, the fault to be mistakenly treated as NUMA hint
fault.
In addition, even if those maps could partcipate in NUMA
balancing, it wouldn't provide any benefit since we are unable
to determine physical page's node (even if/when VNUMA is
implemented).
Marking grant maps' VMAs as VM_IO will exclude them from being
part of NUMA balancing.

With the actual code, read_alarm() always returns -EINVAL when called
during the RTC device registration. This prevents from retrieving an
already configured alarm in hardware.
This patch fixes the issue by moving the HAS_ALARM bit configuration
(if supported by the hardware) above the rtc_device_register() call.

This reverts commit 348a65cdcb.
Incorrect page table manipulation that does not respect the ARM ARM
recommended break-before-make sequence may lead to TLB conflicts. The
contiguous PTE patch makes the system even more susceptible to such
errors by changing the mapping from a single page to a contiguous range
of pages. An additional TLB invalidation would reduce the risk window,
however, the correct fix is to switch to a temporary swapper_pg_dir.
Once the correct workaround is done, the reverted commit will be
re-applied.

Under some unusual context-switching patterns, it is possible to end up
with multiple threads from the same mm running concurrently with
different ASIDs:
1. CPU x schedules task t with mm p containing ASID a and generation g
This task doesn't block and the CPU doesn't context switch.
So:
* per_cpu(active_asid, x) = {g,a}
* p->context.id = {g,a}
2. Some other CPU generates an ASID rollover. The global generation is
now (g + 1). CPU x is still running t, with no context switch and
so per_cpu(reserved_asid, x) = {g,a}
3. CPU y schedules task t', which shares mm p with t. The generation
mismatches, so we take the slowpath and hit the reserved ASID from
CPU x. p is then updated so that p->context.id = {g + 1,a}
4. CPU y schedules some other task u, which has an mm != p.
5. Some other CPU generates *another* CPU rollover. The global
generation is now (g + 2). CPU x is still running t, with no context
switch and so per_cpu(reserved_asid, x) = {g,a}.
6. CPU y once again schedules task t', but now *fails* to hit the
reserved ASID from CPU x because of the generation mismatch. This
results in a new ASID being allocated, despite the fact that t is
still running on CPU x with the same mm.
Consequently, TLBIs (e.g. as a result of CoW) will not be synchronised
between the two threads.
This patch fixes the problem by updating all of the matching reserved
ASIDs when we hit on the slowpath (i.e. in step 3 above). This keeps
the reserved ASIDs in-sync with the mm and avoids the problem.
