commit 4aa819c79bb73f3d1bdf5244d0a0f7f15261504c upstream.
When building this driver on arm64, we get a harmless type
mismatch warning:
drivers/dma/bcm2835-dma.c: In function 'bcm2835_dma_fill_cb_chain_with_sg':
include/linux/kernel.h:743:17: warning: comparison of distinct pointer types lacks a cast

This changes the type of the 'len' variable to size_t, which
avoids the problem.

commit 7ad8fb61c4abf589596f0a4da34d987471481569 upstream.
The kbuild test robot reported a compile error if HIST_TRIGGERS was
enabled but nothing else that selected TRACING was configured in.
HIST_TRIGGERS should directly select it and not rely on anything else
to do it.

commit c146a2b98eb5898eb0fab15a332257a4102ecae9 upstream.
When looking up the nearest SLUB object for a given address, correctly
calculate its offset if SLAB_RED_ZONE is enabled for that cache.
Previously, when KASAN had detected an error on an object from a cache
with SLAB_RED_ZONE set, the actual start address of the object was
miscalculated, which led to random stacks having been reported.
When looking up the nearest SLUB object for a given address, correctly
calculate its offset if SLAB_RED_ZONE is enabled for that cache.

commit 9ef3c5112139cc5c5666ee096e05bc1e00e94015 upstream.
tdev->signal is not set NULL after it's freed. This will cause random
exceptions when the stale pointer is accessed after tdev->signal is
freed. Also, since tdev->signal allocation is skipped the next time
it's written, this leads to continuous fault finally leading to the
total death of the system.

commit d69e40fade97b6b19837c1772efa516bc28cc870 upstream.
The vsp1_pipeline_reset() function loops over pipeline inputs and output
and resets them. When doing so it assumes both that the pipeline has
been correctly configured with an output, and that inputs are are stored
in the pipe inputs array at positions 0 to num_inputs-1.
Both the assumptions are incorrect. The pipeline might need to be reset
after a failed attempts to configure it, without any output specified.
Furthermore, inputs are stored in a positiong equal to their RPF index,
possibly creating holes in the inputs array if the RPFs are not used in
sequence.
Fix both issues by looping over the whole inputs array and skipping
unused entries, and ignoring the output when not set.

commit cdf8b4633075f2171d440d2e37c9c2609019a81a upstream.
AT_VECTOR_SIZE_ARCH should be defined with the maximum number of
NEW_AUX_ENT entries that ARCH_DLINFO can contain, but it wasn't defined
for tile at all even though ARCH_DLINFO will contain one NEW_AUX_ENT for
the VDSO address.
This shouldn't be a problem as AT_VECTOR_SIZE_BASE includes space for
AT_BASE_PLATFORM which tile doesn't use, but lets define it now and add
the comment above ARCH_DLINFO as found in several other architectures to
remind future modifiers of ARCH_DLINFO to keep AT_VECTOR_SIZE_ARCH up to
date.

commit 52d210d961a62a9662e27f14d6505d6741b2fb02 upstream.
In ee1d267423a1 ("pstore: add pstore unregister") I added:
.owner = THIS_MODULE,
in both pstore_fs_type and pstore_file_operations to increase a reference
count when pstore filesystem is mounted and pstore file is opened.
But, it's repetitive. There is no need to increase the opened reference
count. We only need to increase the mounted reference count. When a file
is opened, the filesystem can't be unmounted. Hence the pstore module
can't be unloaded either.
So I drop the opened reference count in this patch.

commit 52b9c330c6a8a4b5a1819bdaddf4ec76ab571e81 upstream.
If ->queue_rq() returns BLK_MQ_RQ_QUEUE_OK, we use continue and skip
over the rest of the loop body. However, dptr is assigned later in the
loop body, and the BLK_MQ_RQ_QUEUE_OK case is exactly the case that we'd
want it for.
NVMe isn't actually using BLK_MQ_F_DEFER_ISSUE yet, nor is any other
in-tree driver, but if the code's going to be there, it might as well
work.

commit 06dfe5cc0cc684e735cb0232fdb756d30780b05d upstream.
SA1111 PCMCIA was broken when PCMCIA switched to using dev_pm_ops for
the PCMCIA socket class. PCMCIA used to handle suspend/resume via the
socket hosting device, which happened at normal device suspend/resume
time.
However, the referenced commit changed this: much of the resume now
happens much earlier, in the noirq resume handler of dev_pm_ops.
However, on SA1111, the PCMCIA device is not accessible as the SA1111
has not been resumed at _noirq time. It's slightly worse than that,
because the SA1111 has already been put to sleep at _noirq time, so
suspend doesn't work properly.
Fix this by converting the core SA1111 code to use dev_pm_ops as well,
and performing its own suspend/resume at noirq time.
This fixes these errors in the kernel log:
pcmcia_socket pcmcia_socket0: time out after reset
pcmcia_socket pcmcia_socket1: time out after reset
and the resulting lack of PCMCIA cards after a S2RAM cycle.

commit c2f321126e31cd69365e65ecd4a7c774e4fc71d2 upstream.
The current implementation only works if the da9xxx devices are added
before their drivers are registered. Only then it can apply the fixes to
both devices. Otherwise, the driver for the first device gets probed
before the fix for the second device can be applied. This is what
fails when using the IP core switcher or when having the i2c master
driver as a module.
So, we need to disable both da9xxx once we detected one of them. We now
use i2c_transfer with hardcoded i2c_messages and device addresses, so we
don't need the da9xxx client devices to be instantiated. Because the
fixup is used on specific boards only, the addresses are not going to
change.

In commit 99fc5ba0bfb6 ("ARM: dts: imx6sx: add i.mx6sx sabreauto board

commit c488f0071eacd10a290df4fb34bbdeb4eb8e7888 upstream.
The voltage ranges listed here are wrong. The pma8084 pldo
supports three different overlapping voltage ranges with
differing step sizes and the pma8084 ftsmps supports two. These
ranges can be seen in the "native" spmi regulator driver
(qcom_spmi-regulator.c) at pldo_ranges[] and ftsmps_ranges[]
respectively. Port these ranges over to the RPM SMD regulator
driver so that we list the appropriate set of supported voltages
on these types of regulators.

commit 93bfe79b03365f410aa91caf04263173c008ecdf upstream.
The mvs1 and mvs2 switches are actually called 5vs1 and 5vs2 on
some datasheets. Let's rename them to match the datasheets and
also match the RPM based regulator driver which calls these by
their 5vs names (see qcom_smd-regulator.c). There aren't any
users of these regulators so far, so there aren't any concerns of
DT ABI breakage here. While we're here making updates to the
switches, also mandate usage of the OCP irq for these switches
too.

commit c2588393e6315ab68207323d37d2a73713d6bc81 upstream.
The original commit adding support for continuous voltage mode didn't
handle the regulator ramp delay properly. It treated the delay as a
fixed delay in uS despite the property being defined as uV / uS. Let's
adjust it. Luckily there appear to be no users of this ramp delay for
PWM regulators (as per grepping through device trees in linuxnext).
Note also that the upper bound of usleep_range probably shouldn't be a
full 1 ms longer than the lower bound since I've seen plenty of hardware
with a ramp rate of ~5000 uS / uV and for small jumps the total delays
are in the tens of uS. 1000 is way too much. We'll try to be dynamic
and use 10%.
NOTE: This commit doesn't add support for regulator-enable-ramp-delay.
That could be done in a future patch when someone has a user of that
featre.
Though this patch is shows as "fixing" a bug, there are no actual known
users of continuous mode PWM regulator w/ ramp delay in mainline and so
this likely won't have any effect on anyone unless they are working
out-of-tree with private patches. For anyone in this state, it is
highly encouraged to also pick Boris Brezillon's WIP patches to get
yourself a reliable and glitch-free regulator.

commit dbb50887c8f619fc5c3489783ebc3122bc134a31 upstream.
During an audit for sk_filter(), we found that rx_busy_skb handling
in l2cap_sock_recv_cb() and l2cap_sock_recvmsg() looks not quite as
intended.
The assumption from commit e328140fdacb ("Bluetooth: Use event-driven
approach for handling ERTM receive buffer") is that errors returned
from sock_queue_rcv_skb() are due to receive buffer shortage. However,
nothing should prevent doing a setsockopt() with SO_ATTACH_FILTER on
the socket, that could drop some of the incoming skbs when handled in
sock_queue_rcv_skb().
In that case sock_queue_rcv_skb() will return with -EPERM, propagated
from sk_filter() and if in L2CAP_MODE_ERTM mode, wrong assumption was
that we failed due to receive buffer being full. From that point onwards,
due to the to-be-dropped skb being held in rx_busy_skb, we cannot make
any forward progress as rx_busy_skb is never cleared from l2cap_sock_recvmsg(),
due to the filter drop verdict over and over coming from sk_filter().
Meanwhile, in l2cap_sock_recv_cb() all new incoming skbs are being
dropped due to rx_busy_skb being occupied.
Instead, just use __sock_queue_rcv_skb() where an error really tells that
there's a receive buffer issue. Split the sk_filter() and enable it for
non-segmented modes at queuing time since at this point in time the skb has
already been through the ERTM state machine and it has been acked, so dropping
is not allowed. Instead, for ERTM and streaming mode, call sk_filter() in
l2cap_data_rcv() so the packet can be dropped before the state machine sees it.

Update the code to make "brl=" option work again and replace memcmp()

commit 305723ab439e14debc1d339aa04e835d488b8253 upstream.
Malta boards used with CPU emulators feature a switch to disable use of
an IOCU. Software has to check this switch & ignore any present IOCU if
the switch is closed. The read used to do this was unsafe for 64 bit
kernels, as it simply casted the address 0xbf403000 to a pointer &
dereferenced it. Whilst in a 32 bit kernel this would access kseg1, in a
64 bit kernel this attempts to access xuseg & results in an address
error exception.
Fix by accessing a correctly formed ckseg1 address generated using the
CKSEG1ADDR macro.
Whilst modifying this code, define the name of the register and the bit
we care about within it, which indicates whether PCI DMA is routed to
the IOCU or straight to DRAM. The code previously checked that bit 0 was
also set, but the least significant 7 bits of the CONFIG_GEN0 register
contain the value of the MReqInfo signal provided to the IOCU OCP bus,
so singling out bit 0 makes little sense & that part of the check is
dropped.

Generic kernel code implements a weak version of set_orig_insn that
moves cached 'insn' from arch_uprobe to the original code location when
the trap is removed.
MIPS variant used arch_uprobe->orig_inst which was never initialised
properly, so this code only inserted a nop instead of the original
instruction. With that change orig_inst can also be safely removed.

commit 3a402a709500c5a3faca2111668c33d96555e35a upstream.
When TIF_SINGLESTEP is set for a task, the single-step state machine is
enabled and we must take care not to reset it to the active-not-pending
state if it is already in the active-pending state.
Unfortunately, that's exactly what user_enable_single_step does, by
unconditionally setting the SS bit in the SPSR for the current task.
This causes failures in the GDB testsuite, where GDB ends up missing
expected step traps if the instruction being stepped generates another
trap, e.g. PTRACE_EVENT_FORK from an SVC instruction.
This patch fixes the problem by preserving the current state of the
stepping state machine when TIF_SINGLESTEP is set on the current thread.

commit 117e5e9c4cfcb7628f08de074fbfefec1bb678b7 upstream.
If the bootloader uses the long descriptor format and jumps to
kernel decompressor code, TTBCR may not be in a right state.
Before enabling the MMU, it is required to clear the TTBCR.PD0
field to use TTBR0 for translation table walks.
The commit dbece45894d3a ("ARM: 7501/1: decompressor:
reset ttbcr for VMSA ARMv7 cores") does the reset of TTBCR.N, but
doesn't consider all the bits for the size of TTBCR.N.
Clear TTBCR.PD0 field and reset all the three bits of TTBCR.N to
indicate the use of TTBR0 and the correct base address width.

commit 727653d6ce7103b245eb8041f55dd5885f4c3289 upstream.
gic_raise_softirq() walks the list of cpus using for_each_cpu(), it calls
gic_compute_target_list() which advances the iterator by the number of
CPUs in the cluster.
If gic_compute_target_list() reaches the last CPU it leaves the iterator
pointing at the last CPU. This means the next time round the for_each_cpu()
loop cpumask_next() will be called with an invalid CPU.
This triggers a warning when built with CONFIG_DEBUG_PER_CPU_MAPS:

commit 07c72d7d54d138eb2ca37709a5a3d55fbcc01536 upstream.
Send a zero length last streaming mode message for loopback
connections to synchronize between accepting QP and connecting QP.
This avoids data transfer to start on the accepting QP before
the connecting QP is in RTS. Also remove function i40iw_loopback_nop()
as it is no longer used.

commit 5dfd5e5e3bc68ab3912acc712c8180942094fc69 upstream.
Add NULL check for pdata and pdata->addr before the memcpy in
i40iw_form_cm_frame(). This fixes a NULL pointer de-reference
which occurs when the MPA private data pointer is NULL. Also
only copy pdata->size bytes in the memcpy to prevent reading
past the length of the private data buffer provided by upper layer.
