	Currently the floating point stress tests mostly support testing that the data they are checking can be disrupted from a signal handler triggered by SIGUSR1. This is not properly implemented for all the tests and in testing is frequently modified to just handle the signal without corrupting data in order to ensure that signal handling does not corrupt data. Directly support this usage by installing a SIGUSR2 handler which simply counts the signal delivery.

2020-09-18	selftests: arm64: Add stress tests for FPSMID and SVE context switching	Mark Brown	1	-0/+11
	Add programs sve-test and fpsimd-test which spin reading and writing to the SVE and FPSIMD registers, verifying the operations they perform. The intended use is to leave them running to stress the context switch code's handling of these registers which isn't compatible with what kselftest does so they're not integrated into the framework but there's no other obvious testsuite where they fit so let's store them here. These tests were written by Dave Martin and lightly adapted by me.
