Pull locking changes from Ingo Molnar:
"The main changes in this cycle were:- More gradual enhancements to atomic ops: new atomic*_read_ctrl()
ops, synchronize atomic_{read,set}() ordering requirements between
architectures, add atomic_long_t bitops. (Peter Zijlstra)- Add _{relaxed|acquire|release}() variants for inc/dec atomics and
use them in various locking primitives: mutex, rtmutex, mcs, rwsem.
This enables weakly ordered architectures (such as arm64) to make
use of more locking related optimizations. (Davidlohr Bueso)- Implement atomic[64]_{inc,dec}_relaxed() on ARM. (Will Deacon)
- Futex kernel data cache footprint micro-optimization. (Rasmus
Villemoes)- pvqspinlock runtime overhead micro-optimization. (Waiman Long)
- misc smaller fixlets"

Implement COMEDI asynchronous commands on the fake analog output
subdevice. This is useful for testing asynchronous commands in the
"write" direction when no real hardware is available.A normal kernel timer is used to drive the command. The new timer
expiry function `waveform_ao_timer()` handles whole "scans" at a time
according to the number of scan period that have elapsed since the last
scan. Data for each channel in the scan is written to the internal
loopback array `devpriv->ao_loopbacks[]` and can be read back on the
analog input channels. However, if several scan periods are outstanding
in the timer expiry function, only the latest available scan data is
written to the loopback array in order to save processing time. The
expiry function also checks for underrun conditions, and checks for
normal termination of the asynchronous command when a "stop" scan count
is reached.After the command is tested by `waveform_ao_cmdtest()` and set up by
`waveform_ao_cmd()`, it is not started until an internal trigger
function `waveform_ao_inttrig_start()` is called as a result of the user
performing an `INSN_INTTRIG` instruction on the subdevice. The command
is stopped when the "cancel" handler `waveform_ao_cancel()` is called.
This may be due to the command terminating due to completion or an
error, or as a result of the user cancelling the command.Signed-off-by: Ian Abbott

`waveform_ai_interrupt()` is a timer expiry function used to generate
fake waveform data for an analog input subdevice. Rename it to
`waveform_ai_timer()`.Signed-off-by: Ian Abbott
Reviewed-by: H Hartley Sweeten
Signed-off-by: Greg Kroah-Hartman -
For asynchronous command handling on the analog input subdevice, a
kernel timer routine is used to generate the fake waveform data. A
"scan" consists of a number of conversions separated in time by a
conversion period. Successive scans are separated in time by a scan
period, which is at least the conversion period multiplied by the number
of conversions per scan. Currently, the timer routine does not generate
any data until the end of a scan period, generating whole scans of data
at a time. Change it to generate data at the end of each conversion
period, with an extra delay after the final conversion in each scan if
necessary. Use new member `ai_convert_time` in the private data
structure `struct waveform_private` to keep track of when the next
conversion is due. This replaces the old member `ai_last_scan_time`
which kept track of the time of the previous scan.Signed-off-by: Ian Abbott
