Currently in fp-stress we test signal delivery to the test threads by sending SIGUSR2 which simply counts how many signals are delivered. The test programs now also all have a SIGUSR1 handler which for the threads doing userspace testing additionally modifies the floating point register state in the signal handler, verifying that when we return the saved register state is restored from the signal context as expected. Switch over to triggering that to validate that we are restoring as expected.

KSelfTest ARM64
===============
- These tests are arm64 specific and so not built or run but just skipped
completely when env-variable ARCH is found to be different than 'arm64'
and `uname -m` reports other than 'aarch64'.
- Holding true the above, ARM64 KSFT tests can be run within the KSelfTest
framework using standard Linux top-level-makefile targets:
$ make TARGETS=arm64 kselftest-clean
$ make TARGETS=arm64 kselftest
or
$ make -C tools/testing/selftests TARGETS=arm64 \
INSTALL_PATH=<your-installation-path> install
or, alternatively, only specific arm64/ subtargets can be picked:
$ make -C tools/testing/selftests TARGETS=arm64 ARM64_SUBTARGETS="tags signal" \
INSTALL_PATH=<your-installation-path> install
Further details on building and running KFST can be found in:
