staging: speakup: make ttyio synths use device name
This patch introduces new module parameter, dev, which takes a string
representing the device that the external synth is connected to, e.g.
ttyS0, ttyUSB0 etc. This is then used to communicate with the synth.
That way, speakup can support more than ttyS*. As of this patch, it
only supports ttyS*, ttyUSB* and selected synths for lp*. dev parameter
is only available for tty-migrated synths.
Users will either use dev or ser as both serve same purpose. This patch
maintains backward compatility by allowing ser to be specified. When
both are specified, whichever is non-default, i.e. not ttyS0, is used.
If both are non-default then dev is used.

Jonathan writes:
Second set of IIO new device support, features and cleanups for the 4.13 cycle.
A few reverts here. One was a general failure to notice a device was already
supported by another driver. The second is due to a review comment pointing
out that the original patch was a bad idea and would break existing systems.
Reverts
* bma180
- Revert addition of support for the BMA250E it is already supported by
the bmc150-accel and better supported at that. Oops.
* hi8435
- The fix for cleanup of the reset gpio stuff isn't a good way to go. It
breaks systems where an inverting level convertor is used. The right fix
is to make the original devicetree correct - even if it involves patching
the devicetree in kernel.
New Device Support
* stm32-adc
- STM32H7 support and bindings.
Features
* core
- add a hardware triggered operating mode for systems in which the actual
trigger is never seen by the kernel. This is typically only used when
a device 'can' use other triggers, but if a particular magic one is
enabled the interrupt is effectively handled in hardware and we never see
it.
* st-lsm6dsx
- support active low interrupts.
* stm32-adc
- Make the core adc clock optional as not all hardware supported requires it.
- Make the bus clock optional in the per instance driver as it may be shared
by all instances of the ADC and is handled by the core.
- Rework to have a data structure representing the device type specific
elements.
* stm32-trigger (and counter)
- Use the INDIO_HARDWARE_TRIGGERED_MODE where appropriate.
- Add an attribute to configure device modes for quadrature counting etc.
Clean ups and minor fixes
* IIO core.
- use __sysfs_match_string() helper rather than open coding the same.
* ad7791
- use sysfs_match_string() helper rather than open coding the same.
* aspeed-adc
- handle return value of clk_prepare_enable
* cpcap
- Fix default register values and ensure the battery thermistor is enabled
correctly.
- Fix the reported die temperature where we can - docs are lacking.
- Remove the hung interrupt quirk as no longer happens due to fix in the
mfd driver.
* hi8435
- Remove &s from hi8435_info definition as unneeded and inconsistent.
* hid-sensor-trgger
- Add kconfig depends on IIO_BUFFER (fixes patch in previous series)
* ina2xx
- Make the use of iio_info_mask* elements consistent for all channels.
This doesn't have any visible effect, but acts as clear documentation of
which channels various resulting attributes apply to.
* lpc32xx
- handle the return value of clk_prepare_enable.
* meson-saradc
- NULL instead of 0 for pointer.
* mma9551
- use NULL for GPIO connection ID to aid implementation fo ACPI support.
Here the connection ID doesn't actually tell us anything and it is much
easier to deal with the driver if it's not there.
* mpu6050
- Fix lock issues through use of a local mux.
- Replace sprintf with scnprintf as appropriate.
- Check whoami against all known values. This allows for a small number of
boards where we are really fishing for the part not being present at all.
It is unfortunately common to have undescribed changes to use newer chips.
We paper over this but just emitting a warning for those cases as long as
we know about.
* mxs-lradc
- Fix some non static warnings.
* rcar-adc
- Part of making the naming for this part consistent across the kernel.
* st_accel
- drop some spi_device_id entries for variants with no SPI support
* st_magn
- drop some spi_device_id entries for variants with no SPI support.
* sx9500
- Use devm_gpiod_get instead of indexed value with an index of 0 on all
occasions.
* twl4030
- Drop unused twl4030_get_madc_conversion as callers removed now throughout
kernel.
- Unexport twl4030_madc_conversion() as no used only within this driver.
- Drop twl4030_madc_user_params as not used now.
- Drop twl4030_madc_request.func_cb as not used now.
- Fold the twl4030-madc.h header into the driver as no longer used anywhere
else in the kernel.
* xilinx
- Handle the return value of clk_prepare_enable

staging: speakup: fix synth caching when synth init fails
synths[] array caches currently loaded synths. synth_add checks
synths[] before adding a new one. It however ignores the result of
do_synth_init. So when do_synth_init fails, the failed synth is still
cached. Since, as a result module loading fails too, synth_remove -
which is responsible for removing the cached synth - is never called.
Next time the failing synth is added again it succeeds because
synth_add finds it cached inside synths[].
This patch fixes this by caching a synth only after do_synth_init
succeeds.

staging: ccree: register setkey for none hash macs
The original ccree driver was registering a useless setkey
method even for non-MAC hash transformations. Somewhere
around v4.9 a check was added that failed hash operations
if a setkey method was registered but was not called,
so during the initial upstream port code was added to
only register the setkey method for MAC type hash transform.
Unfortunately, the ccree driver also registers non-hash based
MAC transforms and the code had a logic error that stopped
it registering a setkey callback even for those, thus rendering
them useless.
This commit fixes the logic mistake, thus correctly registering
a setkey method only for MAC transformations, leaving it out
for non-MAC ones, whether they are hash based on not.

staging: lustre: lustre: resolve "use spaces between elements" checkpatch errors
Due to the way the DFID was embedded in our debug strings checkpatch
would report the following error:
CHECK: Concatenated strings should use spaces between elements
This patch introduces proper space to resolve these reports.

mm: larger stack guard gap, between vmas
Stack guard page is a useful feature to reduce a risk of stack smashing
into a different mapping. We have been using a single page gap which
is sufficient to prevent having stack adjacent to a different mapping.
But this seems to be insufficient in the light of the stack usage in
userspace. E.g. glibc uses as large as 64kB alloca() in many commonly
used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX]
which is 256kB or stack strings with MAX_ARG_STRLEN.
This will become especially dangerous for suid binaries and the default
no limit for the stack size limit because those applications can be
tricked to consume a large portion of the stack and a single glibc call
could jump over the guard page. These attacks are not theoretical,
unfortunatelly.
Make those attacks less probable by increasing the stack guard gap
to 1MB (on systems with 4k pages; but make it depend on the page size
because systems with larger base pages might cap stack allocations in
the PAGE_SIZE units) which should cover larger alloca() and VLA stack
allocations. It is obviously not a full fix because the problem is
somehow inherent, but it should reduce attack space a lot.
One could argue that the gap size should be configurable from userspace,
but that can be done later when somebody finds that the new 1MB is wrong
for some special case applications. For now, add a kernel command line
option (stack_guard_gap) to specify the stack gap size (in page units).
Implementation wise, first delete all the old code for stack guard page:
because although we could get away with accounting one extra page in a
stack vma, accounting a larger gap can break userspace - case in point,
a program run with "ulimit -S -v 20000" failed when the 1MB gap was
counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK
and strict non-overcommit mode.
Instead of keeping gap inside the stack vma, maintain the stack guard
gap as a gap between vmas: using vm_start_gap() in place of vm_start
(or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few
places which need to respect the gap - mainly arch_get_unmapped_area(),
and and the vma tree's subtree_gap support for that.
