Botched calculation of number of pages. As the result,
we were dropping pieces when doing splice to pipe from
e.g. 9p.

Pull parisc fixes from Helge Deller:
"On parisc we were still seeing occasional random segmentation faults
and memory corruption on SMP machines. Dave Anglin then looked again
at the TLB related code and found two issues in the PCI DMA and
generic TLB flush functions.
Then, in our startup code we had some timing of the cache and TLB
functions to calculate a threshold when to use a complete TLB/cache
flush or just to flush a specific range. This code produced a race
with newly started CPUs and thus lead to occasional kernel crashes
(due to stale TLB/cache entries). The patch by Dave fixes this issue
by flushing the local caches before starting secondary CPUs and by
removing the race.
The last problem fixed by this series is that we quite often suffered
from hung tasks and self-detected stalls on the CPUs. It was somehow
clear that this was related to the (in v4.7) newly introduced cr16
clocksource and the own implementation of sched_clock(). I replaced
the open-coded sched_clock() function and switched to the generic
sched_clock() implementation which seems to have fixed this isse as
well.
All patches have been sucessfully tested on a variety of machines,
including our debian buildd servers.
All patches (beside the small pr_cont fix) are tagged for stable
releases"

CONFIG_MODVERSIONS has been broken for pretty much the whole 4.9 series,
and quite frankly, nobody has cared very deeply. We absolutely know how
to fix it, and it's not _complicated_, but it's not exactly pretty
either.
This oneliner fixes it without the ugliness, and allows for further
future cleanups.

Pull ACPI fixes from Rafael Wysocki:
"Two ACPI fixes for 4.9-rc7.
One of them reverts a recent ACPI commit that attempted to improve
reboot/power-off on some systems, but introduced problems elsewhere,
and the other one fixes kernel builds with the new WDAT watchdog
driver enabled in some configurations.
Specifics:
- Revert the recent commit that caused the ACPI _PTS method to be
executed in the power-off/reboot code path (as per the
specification) in an attempt to improve things on some systems
(apparently expecting _PTS to be executed in that code path), but
broke power-off/reboot on at least one other machine (Rafael
Wysocki).
- Fix kernel builds with the new WDAT watchdog driver enabled in some
configurations by explicitly selecting WATCHDOG_CORE when enabling
the WDAT watchdog driver (Mika Westerberg)"

This is the second issue I noticed in reviewing the parisc TLB code.
The fic instruction may use either the instruction or data TLB in
flushing the instruction cache. Thus, on machines with a split TLB, we
should also flush the data TLB after setting up the temporary alias
registers.
Although this has no functional impact, I changed the pdtlb and pitlb
instructions to consistently use the index register %r0. These
instructions do not support integer displacements.
Tested on rp3440 and c8000.

We are still troubled by occasional random segmentation faults and
memory memory corruption on SMP machines. The causes quite a few
package builds to fail on the Debian buildd machines for parisc. When
gcc-6 failed to build three times in a row, I looked again at the TLB
related code. I found a couple of issues. This is the first.
In general, we need to ensure page table updates and corresponding TLB
purges are atomic. The attached patch fixes an instance in pci-dma.c
where the page table update was not guarded by the TLB lock.
Tested on rp3440 and c8000. So far, no further random segmentation
faults have been observed.

From the backtrace, cpu1 is in smp_callin:
void __init smp_callin(void)
{
int slave_id = cpu_now_booting;
smp_cpu_init(slave_id);
preempt_disable();
flush_cache_all_local(); /* start with known state */
flush_tlb_all_local(NULL);
local_irq_enable(); /* Interrupts have been off until now */
cpu_startup_entry(CPUHP_AP_ONLINE_IDLE);
So, it has just flushed its caches and the TLB. It would seem either the
flushes in parisc_setup_cache_timing or smp_callin have corrupted kernel
memory.
The attached patch reworks parisc_setup_cache_timing to remove the races
in setting the cache and TLB flush thresholds. It also corrects the
number of bytes flushed in the TLB calculation.
The patch flushes the cache and TLB on cpu0 before starting the
secondary processors so that they are started from a known state.
Tested with a few reboots on c8000.

The kernel WARNs and then crashes today if wm8994_device_init() fails
after calling devm_regulator_bulk_get().
That happens because there are multiple devices involved here and the
order in which managed resources are freed isn't correct.
The regulators are added as children of wm8994->dev. Whereas,
devm_regulator_bulk_get() receives wm8994->dev as the device, though it
gets the same regulators which were added as children of wm8994->dev
earlier.
During failures, the children are removed first and the core eventually
calls regulator_unregister() for them. As regulator_put() was never done
for them (opposite of devm_regulator_bulk_get()), the kernel WARNs at
WARN_ON(rdev->open_count);
And eventually it crashes from debugfs_remove_recursive().

This fixes CVE-2016-8650.
If mpi_powm() is given a zero exponent, it wants to immediately return
either 1 or 0, depending on the modulus. However, if the result was
initalised with zero limb space, no limbs space is allocated and a
NULL-pointer exception ensues.
Fix this by allocating a minimal amount of limb space for the result when
the 0-exponent case when the result is 1 and not touching the limb space
when the result is 0.
This affects the use of RSA keys and X.509 certificates that carry them.

Tune dsi frame rate by pixel clock, dsi add some extra signal (i.e.
Tlpx, Ths-prepare, Ths-zero, Ths-trail,Ths-exit) when enter and exit LP
mode, those signals will cause h-time larger than normal and reduce FPS.
So need to multiply a coefficient to offset the extra signal's effect.

The commit 8dfbcc4351a0 ("[media] xc2028: avoid use after free") tried
to address the reported use-after-free by clearing the reference.
However, it's clearing the wrong pointer; it sets NULL to
priv->ctrl.fname, but it's anyway overwritten by the next line
memcpy(&priv->ctrl, p, sizeof(priv->ctrl)).
OTOH, the actual code accessing the freed string is the strcmp() call
with priv->fname:
if (!firmware_name[0] && p->fname &&
priv->fname && strcmp(p->fname, priv->fname))
free_firmware(priv);
where priv->fname points to the previous file name, and this was
already freed by kfree().
For fixing the bug properly, this patch does the following:
- Keep the copy of firmware file name in only priv->fname,
priv->ctrl.fname isn't changed;
- The allocation is done only when the firmware gets loaded;
- The kfree() is called in free_firmware() commonly

tile: avoid using clocksource_cyc2ns with absolute cycle count
|
|
For large values of "mult" and long uptimes, the intermediate
result of "cycles * mult" can overflow 64 bits. For example,
the tile platform calls clocksource_cyc2ns with a 1.2 GHz clock;
we have mult = 853, and after 208.5 days, we overflow 64 bits.
Since clocksource_cyc2ns() is intended to be used for relative
cycle counts, not absolute cycle counts, performance is more
importance than accepting a wider range of cycle values. So,
just use mult_frac() directly in tile's sched_clock().
Commit 4cecf6d401a0 ("sched, x86: Avoid unnecessary overflow
in sched_clock") by Salman Qazi results in essentially the same
generated code for x86 as this change does for tile. In fact,
a follow-on change by Salman introduced mult_frac() and switched
to using it, so the C code was largely identical at that point too.
Peter Zijlstra then added mul_u64_u32_shr() and switched x86
to use it. This is, in principle, better; by optimizing the
64x64->64 multiplies to be 32x32->64 multiplies we can potentially
save some time. However, the compiler piplines the 64x64->64
multiplies pretty well, and the conditional branch in the generic
mul_u64_u32_shr() causes some bubbles in execution, with the
result that it's pretty much a wash. If tilegx provided its own
implementation of mul_u64_u32_shr() without the conditional branch,
we could potentially save 3 cycles, but that seems like small gain
for a fair amount of additional build scaffolding; no other platform
currently provides a mul_u64_u32_shr() override, and tile doesn't
currently have an <asm/div64.h> header to put the override in.
Additionally, gcc currently has an optimization bug that prevents
it from recognizing the opportunity to use a 32x32->64 multiply,
and so the result would be no better than the existing mult_frac()
until such time as the compiler is fixed.
For now, just using mult_frac() seems like the right answer.

When PCIe port PM is not enabled (system BIOS is pre-2015 or the
pcie_port_pm=off parameter is set), legacy ATPX PM should still be
marked as supported. Otherwise the GPU can fail to power on after
runtime suspend. This affected a Dell Inspiron 5548.
Ideally the BIOS date in the PCI core is lowered to 2013 (the first year
where hybrid graphics platforms using power resources was introduced),
but that seems more risky at this point and would not solve the
pcie_port_pm=off issue.

When user tried to read some fields like hysteresis from IIO sysfs on some
systems, it fails. The reason is that this field is a byte field and caller
of sensor_hub_get_feature() passes a buffer of 4 bytes. Here the function
sensor_hub_get_feature() copies the single byte from the report to the
caller buffer and returns "1" as the number of bytes copied. So caller
can use the return value.
But this is done by multiple callers, so if we just change the
sensor_hub_get_feature so that caller buffer is initialized with 0s
then we don't to change all functions.

"The last push broke algif_hash for all shash implementations, so this
is a follow-up to fix that.
This also fixes a problem in the crypto scatterwalk that triggers a
BUG_ON with certain debugging options due to the new vmalloced-stack
code"
* 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
crypto: scatterwalk - Remove unnecessary aliasing check in map_and_copy
crypto: algif_hash - Fix result clobbering in recvmsg

Pull thermal management fix from Zhang Rui:
"We only have one urgent fix this time.
Commit 3105f234e0ab ("thermal/powerclamp: correct cpu support check"),
which is shipped in 4.9-rc3, fixed a problem introduced by commit
b721ca0d1927 ("thermal/powerclamp: remove cpu whitelist").
But unfortunately, it broke intel_powerclamp driver module auto-
loading at the same time. Thus we need this change to add back module
auto-loading for 4.9"

Pull SCSI fixes from James Bottomley:
"Two small fixes.
One prevents timeouts on mpt3sas when trying to use the secure erase
protocol which causes the erase protocol to be aborted. The second is
a regression in a prior fix which causes all commands to abort during
PCI extended error recovery, which is incorrect because PCI EEH is
independent from what's happening on the FC transport"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: qla2xxx: do not abort all commands in the adapter during EEH recovery
scsi: mpt3sas: Fix secure erase premature termination

Pull clk fixes from Stephen Boyd:
"A handful of driver fixes.
The sunxi fixes are for an incorrect clk tree configuration and a bad
frequency calculation. The other two are fixes for passing the wrong
pointer in drivers recently converted to clk_hw style registration"
* tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux:
clk: efm32gg: Pass correct type to hw provider registration
clk: berlin: Pass correct type to hw provider registration
clk: sunxi: Fix M factor computation for APB1
clk: sunxi-ng: sun6i-a31: Force AHB1 clock to use PLL6 as parent

A correct bugfix introduced a harmless warning that shows up with gcc-7:
fs/nfs/callback.c: In function 'nfs_callback_up':
fs/nfs/callback.c:214:14: error: array subscript is outside array bounds [-Werror=array-bounds]
What happens here is that the 'minorversion == 0' check tells the
compiler that we assume minorversion can be something other than 0,
but when CONFIG_NFS_V4_1 is disabled that would be invalid and
result in an out-of-bounds access.
The added check for IS_ENABLED(CONFIG_NFS_V4_1) tells gcc that this
really can't happen, which makes the code slightly smaller and also
avoids the warning.
The bugfix that introduced the warning is marked for stable backports,
we want this one backported to the same releases.
