The Point of View mobii wintab p800w Bay Trail tablet comes with a Crystal
Cove PMIC, yet uses the LPSS PWM for backlight control, rather then the
Crystal Cove's PWM, so we need to call pwm_add_table() to add a
pwm_backlight mapping for the LPSS pwm despite there being an INT33FD
ACPI device present.
On all Bay Trail devices the _HRV object of the INT33FD ACPI device
will normally return 2, to indicate the Bay Trail variant of the CRC
PMIC is present, except on this tablet where _HRV is 0xffff. I guess this
is a hack to make the windows Crystal Cove PWM driver not bind.
Out of the 44 DSTDs with an INT33FD device in there which I have (from
different model devices) only the pov mobii wintab p800w uses 0xffff for
the HRV.
The byt_pwm_setup code calls acpi_dev_present to check for the presence
of a INT33FD ACPI device which indicates that a CRC PMIC is present and
if the INT33FD ACPI device is present then byt_pwm_setup will not add
a pwm_backlight mapping for the LPSS pwm, so that the CRC PWM will get
used instead.
acpi_dev_present has a hrv parameter, this commit make us pass 2 instead
of -1, so that things still match on normal tablets, but on this special
case with its _HRV of 0xffff, the check will now fail so that the
pwm_backlight mapping for the LPSS pwm gets added fixing backlight
brightness control on this device.

The root cause of the problem is starting hrtimer with an expiry time
already in the past can take more than 20 milliseconds to trigger the
timer function. It can be solved by forward such past timers
immediately, rather than submitting them to hrtimer_start().
In case the timer is periodic, update the target expiration and call
hrtimer_start with it.
v2: Check if the tsc deadline is already expired. Thank you Mika.
v3: Execute the past timers immediately rather than submitting them to
hrtimer_start().
v4: Rearm the periodic timer with advance_periodic_target_expiration() a
simpler version of set_target_expiration(). Thank you Paolo.

Pull rdma fixes from Doug Ledford:
"This is our first pull request of the rc cycle. It's not that it's
been overly quiet, we were just waiting on a few things before sending
this off.
For instance, the 6 patch series from Intel for the hfi1 driver had
actually been pulled in on Tuesday for a Wednesday pull request, only
to have Jason notice something I missed, so we held off for some
testing, and then on Thursday had to respin the series because the
very first patch needed a minor fix (unnecessary cast is all).
There is a sizable hns patch series in here, as well as a reasonably
largish hfi1 patch series, then all of the lines of uapi updates are
just the change to the new official Linux-OpenIB SPDX tag (a bunch of
our files had what amounts to a BSD-2-Clause + MIT Warranty statement
as their license as a result of the initial code submission years ago,
and the SPDX folks decided it was unique enough to warrant a unique
tag), then the typical mlx4 and mlx5 updates, and finally some cxgb4
and core/cache/cma updates to round out the bunch.
None of it was overly large by itself, but in the 2 1/2 weeks we've
been collecting patches, it has added up :-/.
As best I can tell, it's been through 0day (I got a notice about my
last for-next push, but not for my for-rc push, but Jason seems to
think that failure messages are prioritized and success messages not
so much). It's also been through linux-next. And yes, we did notice in
the context portion of the CMA query gid fix patch that there is a
dubious BUG_ON() in the code, and have plans to audit our BUG_ON usage
and remove it anywhere we can.

Since commit d677a4d601 ("Makefile: support flag

plugin under some circumstances.
CONFIG_KCOV=y
CONFIG_KCOV_ENABLE_COMPARISONS=y
Your compiler does not support -fsanitize-coverage=trace-pc
Your compiler does not support -fsanitize-coverage=trace-cmp
Under this condition, $(CFLAGS_KCOV) is not empty but contains a
space, so the following ifeq-conditional is false.
ifeq ($(CFLAGS_KCOV),)
Then, scripts/Makefile.gcc-plugins misses to add sancov_plugin.so to
gcc-plugin-y while the SANCOV plugin is necessary as an alternative
means.

What you can't see just from reading the patch is that in both
cases (ehci->itd_pool and ehci->sitd_pool) there are two
allocation paths -- the two branches of an "if" statement -- and
only one of the paths calls dma_pool_[z]alloc. However, the
memset is needed for both paths, and so it can't be eliminated.
Given that it must be present, there's no advantage to calling
dma_pool_zalloc rather than dma_pool_alloc.

"One cleanup to remove VLAs from the kernel"
* tag 'for-linus-4.17-rc4-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
x86/xen: Remove use of VLAs
Proxying the cpuif accesses at EL2 makes use of vcpu_data_guest_to_host
and co, which check the endianness, which call into vcpu_read_sys_reg...
which isn't mapped at EL2 (it was inlined before, and got moved OoL
with the VHE optimizations).
The result is of course a nice panic. Let's add some specialized
cruft to keep the broken platforms that require this hack alive.
But, this code used vcpu_data_guest_to_host(), which expected us to
write the value to host memory, instead we have trapped the guest's
read or write to an mmio-device, and are about to replay it using the
host's readl()/writel() which also perform swabbing based on the host
endianness. This goes wrong when both host and guest are big-endian,
as readl()/writel() will undo the guest's swabbing, causing the
big-endian value to be written to device-memory.
What needs doing?
A big-endian guest will have pre-swabbed data before storing, undo this.
If its necessary for the host, writel() will re-swab it.
For a read a big-endian guest expects to swab the data after the load.
The hosts's readl() will correct for host endianness, giving us the
device-memory's value in the register. For a big-endian guest, swab it
as if we'd only done the load.
For a little-endian guest, nothing needs doing as readl()/writel() leave
the correct device-memory value in registers.
Tested on Juno with that rarest of things: a big-endian 64K host.
Based on a patch from Marc Zyngier.

driver causing it to use an incorrect transition delay value
which leads to a very high rate of frequency change requests when
the schedutil governor is in use (Prashanth Prakash).

Commit 7ed1c1901f (tools: fix cross-compile var clobbering) removed
setting of LD to $(CROSS_COMPILE)gcc. This broke build of acpica
(acpidump) in power/acpi:
ld: unrecognized option '-D_LINUX'
The tools pass CFLAGS to the linker (incl. -D_LINUX), so revert this
particular change and let LD be $(CC) again. Note that the old behaviour
was a bit different, it used $(CROSS_COMPILE)gcc which was eliminated by
the commit 7ed1c1901f. We use $(CC) for that reason.

Syzbot has reported that it can hit a NULL pointer dereference in
wb_workfn() due to wb->bdi->dev being NULL. This indicates that
wb_workfn() was called for an already unregistered bdi which should not
happen as wb_shutdown() called from bdi_unregister() should make sure
all pending writeback works are completed before bdi is unregistered.
Except that wb_workfn() itself can requeue the work with:
mod_delayed_work(bdi_wq, &wb->dwork, 0);
and if this happens while wb_shutdown() is waiting in:
flush_delayed_work(&wb->dwork);
the dwork can get executed after wb_shutdown() has finished and
bdi_unregister() has cleared wb->bdi->dev.
Make wb_workfn() use wakeup_wb() for requeueing the work which takes all
the necessary precautions against racing with bdi unregistration.

When commit [1] was added, SGID was queried to derive the SMAC address.
Then, later on during a refactor [2], SMAC was no longer needed. However,
the now useless GID query remained. Then during additional code changes
later on, the GID query was being done in such a way that it caused iWARP
queries to start breaking. Remove the useless GID query and resolve the
iWARP breakage at the same time.
This is discussed in [3].

When the kernel was compiled using the UBSAN option,
we saw the following stack trace:
[ 1184.827917] UBSAN: Undefined behaviour in drivers/infiniband/hw/mlx4/mr.c:349:27
[ 1184.828114] signed integer overflow:
[ 1184.828247] -2147483648 - 1 cannot be represented in type 'int'
The problem was caused by calling round_up in procedure
mlx4_ib_umem_calc_optimal_mtt_size (on line 349, as noted in the stack
trace) with the second parameter (1 << block_shift) (which is an int).
The second parameter should have been (1ULL << block_shift) (which
is an unsigned long long).
(1 << block_shift) is treated by the compiler as an int (because 1 is
an integer).
Now, local variable block_shift is initialized to 31.
If block_shift is 31, 1 << block_shift is 1 << 31 = 0x80000000=-214748368.
This is the most negative int value.
Inside the round_up macro, there is a cast applied to ((1 << 31) - 1).
However, this cast is applied AFTER ((1 << 31) - 1) is calculated.
Since (1 << 31) is treated as an int, we get the negative overflow
identified by UBSAN in the process of calculating ((1 << 31) - 1).
The fix is to change (1 << block_shift) to (1ULL << block_shift) on
line 349.

When allocating device data, if there's an allocation failure, the
already allocated memory won't be freed such as per-cpu counters.
Fix memory leaks in exception path by creating a common reentrant
clean up function hfi1_clean_devdata() to be used at driver unload
time and device data allocation failure.
To accomplish this, free_platform_config() and clean_up_i2c() are
changed to be reentrant to remove dependencies when they are called
in different order. This helps avoid NULL pointer dereferences
introduced by this patch if those two functions weren't reentrant.
In addition, set dd->int_counter, dd->rcv_limit,
dd->send_schedule and dd->tx_opstats to NULL after they're freed in
hfi1_clean_devdata(), so that hfi1_clean_devdata() is fully reentrant.

When an invalid num_vls is used as a module parameter, the code
execution follows an exception path where the macro dd_dev_err()
expects dd->pcidev->dev not to be NULL in hfi1_init_dd(). This
causes a NULL pointer dereference.
Fix hfi1_init_dd() by initializing dd->pcidev and dd->pcidev->dev
earlier in the code. If a dd exists, then dd->pcidev and
dd->pcidev->dev always exists.
