Provide infrastructure to do a speculative fault (not holding
mmap_sem).
The not holding of mmap_sem means we can race against VMA
change/removal and page-table destruction. We use the SRCU VMA freeing

There is a deadlock when a CPU is doing a speculative page fault and
another one is calling do_unmap().
The deadlock occurred because the speculative path try to spinlock the
pte while the interrupt are disabled. When the other CPU in the
unmap's path has locked the pte then is waiting for all the
When handling page fault without holding the mmap_sem the fetch of the
pte lock pointer and the locking will have to be done while ensuring
that the VMA is not touched in our back.
So move the fetch and locking operations in a dedicated function.

This is a port on kernel 4.12 of the work done by Peter Zijlstra to
handle page fault without holding the mm semaphore [1].
The idea is to try to handle user space page faults without holding the

This series adds support for Low Power Timer that can be found on
some STM32 devices.
STM32 LPTimer (LPTIM) is a 16-bit timer that provides several
functionalities. This series adds support for following features:
- PWM output (with programmable prescaler, configurable polarity)
- Trigger source f

Add support for LPTIMx_OUT triggers that can be found on some STM32
devices. These triggers can be used then by ADC or DAC.
Typical usage is to configure LPTimer as PWM output (via pwm-stm32-lp)
and have synchronised analog conversions with these triggers.

STM32 Low Power Timer hardware block can be used for:
- PWM generation
- IIO trigger (in sync with PWM)
- IIO quadrature encoder counter
PWM and IIO timer configuration are mixed in the same registers so
we need a multi fonction driver to be able to share those registers.

Do we really need to do that? The SB_* flags are conumeric with the MS_*
