The comments in the handlers for the irritator signal in the test threads for fp-stress suggest that the irritator will corrupt the register state observed by the main thread but this is not the case, instead the FPSIMD and SVE irritators (which are the only ones that are implemented) modify the current register state which is expected to be overwritten on return from the handler by the saved register state. Update the comment to reflect what the handler is actually doing.

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:
