7dfb6d2ec4 staging: rtl8712: cleanup of timeout conversions
This is only an API consolidation to make things more readable.
Instances of  var * HZ / 1000  are replaced by  msecs_to_jiffies(var).
As msecs_to_jiffies will return > 0 if it is passed a value > 0 the
== 0 check is not needed.

509031dd5f staging: xgifb: fix colours on big-endian machines other than powerpc
XGI framebuffer supports big-endian machines, but it's currently
enabled based on __powerpc__ define (which is wrong, as powerpc can
be also little-endian now). Use __BIG_ENDIAN instead. This will fix
wrong colours on such machines.

Tested on parisc with XGI Z7.

737fee1bf6 staging: emxx_udc: Remove nbu2ss_drv_set_dp_info()
This function is an awkward helper for nbu2ss_drv_ep_init().  Most of
its logic is devoted to determining if the current endpoint is ep0,
something the caller can easily do in a single line.  And there is not
a lot going on beyond that.

Move this logic up into nbu2ss_drv_ep_init().  The result is much easier
to understand and the resulting function is still viewable within a
single screen.

76925260a8 staging: comedi: addi_apci_1500: fix array access out of bounds error
The private data 'pm', 'pt', and 'pp' array members hold the trigger mode
parameters for ports A and B. Both ports are 8-bits and the arrays are 16-bits.
Array index 0 defines the AND mode and index 1 the OR mode parameters for both
ports.

The valid triggers to start the async command are 0 to 3 which select the
AND/OR mode for each port.

The 'pb_trig' (the array index for port B) in apci1500_di_inttrig_start() is
incorrect and results in an index of 0 or 2. Fix the calc so that the correct
index (0/1) is used.

2cbf7fe2d5 i2o: move to staging
The I2O layer deals with a technology that to say the least didn't catch on
in the market.

The only relevant products are some of the AMI MegaRAID - which supported I2O
and its native mode (The native mode is faster and runs on Linux), an
obscure crypto ethernet card that's now so many years out of date nobody
would use it, the old DPT controllers, which speak their own dialect and
have their own driver - and ermm.. thats about it.

We also know the code isn't in good shape as recently a patch was proposed
and queried as buggy, which in turn showed the existing code was broken
already by prior "clean up" and nobody had noticed that either.

It's coding style robot code nothing more. Like some forgotten corridor
cleaned relentlessly by a lost Roomba but where no user has trodden in years.

Move it to staging and then to /dev/null.

The headers remain as they are shared with dpt_i2o.

89c468263b Second round of IIO new drivers, functionality and cleanups for the 3.20 cycle.
New drivers and device support:
 * Capella cm3232 ambient light sensor driver.
 * Freescale MMA9553 pedometer and activity monitor. Note this involved a
   refactor of the mma9551 driver to pull out shared elements.
 * Samsung sensor hub (as used in the galaxy gear 2 watch) Core support
   and initial drivers (gyro and accelerometer) more to follow.
   An additional fix was applied on top of this for a build issue
   thrown up by the autobuilders on some platforms.
 * Cosmic Circuits 10001 ADC driver
 * Qualcomm SPMI PMIC voltage ADC driver (current adc merged a while back).
 * Add binding for AK8963 (in capitals) as unfortunately there are bios'
   out there not using lower case.
 
 New functionality
 * Add newe operating mode to the core to allow for non triggered software
   buffers.  This is mostly semantics as previously drivers just claimed they
   had a hardware buffer (when they didn't).
 * Add distance channel type.
 * Add energy channel type.
 * Add velocity channel type and IIO_MOD_ROOT_SUM_SQUARED (i.e. speed when
   our channel type is velocity).
 * Add _debounce_count and _debounce_time filter attributes.  Only really
   make sense for counting types of measurements.  First use is for avoiding
   miss detection of steps prior to walking.
 * Add change event type.   This replaces the briefly present INSTANCE type
   (which hadn't gained any users).  It is more generic as it allows for
   events say every 10 steps rather than every step.
 * Add _calibweight attributes to the ABI (and core support).  Used by
   activity monitors to estimate energy use.  Can imagine there will be
   other uses for this one.
 
 Driver new functionality
 * mma9551 gains runtime pm support.
 * hid-sensors gain PM support.
 
 Cleanup
 * Change calibheight unit to m from cm.  As there are no prior users
   and this was inconsistent with other distance units, it makes sense
   to fix it before hte mma9553 driver which uses it.
 * mpu6050 cleanups and devm_ use.
 * as3935 switch over to PM ops.
 * Fix a few format strings for signed vs unsigned.
 * Fix tcs3414 missindentation
 * Typo in industrialio-event
 * Stop requiring IIO_TRIGGER for IIO_KFIFO_BUF as we have drivers that don't
   need it. No one is quite sure why that dependency was there and it
   seems to not matter.

33692f2759 vm: add VM_FAULT_SIGSEGV handling support
The core VM already knows about VM_FAULT_SIGBUS, but cannot return a
"you should SIGSEGV" error, because the SIGSEGV case was generally
handled by the caller - usually the architecture fault handler.

That results in lots of duplication - all the architecture fault
handlers end up doing very similar "look up vma, check permissions, do
retries etc" - but it generally works.  However, there are cases where
the VM actually wants to SIGSEGV, and applications _expect_ SIGSEGV.

In particular, when accessing the stack guard page, libsigsegv expects a
SIGSEGV.  And it usually got one, because the stack growth is handled by
that duplicated architecture fault handler.

However, when the generic VM layer started propagating the error return
from the stack expansion in commit fee7e49d45 ("mm: propagate error
from stack expansion even for guard page"), that now exposed the
existing VM_FAULT_SIGBUS result to user space.  And user space really
expected SIGSEGV, not SIGBUS.

To fix that case, we need to add a VM_FAULT_SIGSEGV, and teach all those
duplicate architecture fault handlers about it.  They all already have
the code to handle SIGSEGV, so it's about just tying that new return
value to the existing code, but it's all a bit annoying.

This is the mindless minimal patch to do this.  A more extensive patch
would be to try to gather up the mostly shared fault handling logic into
one generic helper routine, and long-term we really should do that
cleanup.

Just from this patch, you can generally see that most architectures just
copied (directly or indirectly) the old x86 way of doing things, but in
the meantime that original x86 model has been improved to hold the VM
semaphore for shorter times etc and to handle VM_FAULT_RETRY and other
"newer" things, so it would be a good idea to bring all those
improvements to the generic case and teach other architectures about
them too.
