[PATCH v2 0/2] kselftest/arm64: fp-stress signal delivery interval improvements

[Mark Brown <broonie@kernel.org>]

One of the things that fp-stress does to stress the floating point
context switching is send signals to the test threads it spawns.
Currently we do this once per second but as suggested by Mark Rutland if
we increase this we can improve the chances of triggering any issues
with context switching the signal handling code.  Do a quick change to 
increase the rate of signal delivery, trying to avoid excessive impact
on emulated platforms, and a further change to mitigate the impact that
this creates during startup.
