Current code assumes that the direction is input if direction_input
function is set.
This might not be the case on GPIOs with programmable direction.

The current code produces XPU violation if get_direction is called just

Add a function that allows initializing the valid_mask from
gpiochip_add_data.
This prevents race conditions during gpiochip initialization.
If the function is not exported, then the old behaviour is respected,
this is, set all gpios as valid.

Some architectures, in this case MIPS, need a couple of legacy alias

is one of those files which define an ABI. Some were
made different due to the desire to be compatible with legacy
architectures, others were mostly direct copies of the i386
definitions, which are now in asm-generic.
This folds the IA64, MIPS, PA-RISC, and Xtensa implementations into
the generic
The IA64 definition of termbits.h is identical to the generic.

The PARISC definition of termbits.h is almost identical to the generic
one, so use the generic one and only redefine a handful of constants.

vgetcyc() is full of barriers, so fetching values out of the vvar
page before vgetcyc() for use after vgetcyc() results in poor code
generation. Put vgetcyc() first to avoid this problem.
Also, pull the tv_sec division into the loop and put all the ts
writes together. The old code wrote ts->tv_s
When a vDSO clock function falls back to the syscall, no special
barriers or ordering is needed, and the syscall fallbacks don't
clobber any memory that is not explicitly listed in the asm
constraints. Remove the "memory" clobber.
This causes minor changes to the generated code, but otherwise has
After reading do_hres() and do_course() and scratching my head a
bit, I figured out why the arithmetic is strange. Document it.

Hi tglx,
This little series applies on top of your patches and, at least on
my laptop, gets back all the performance you lost and then some :)
