In handle_input_signal_copyctx() we use ASSERT_GOOD_CONTEXT() to validate that the context we are saving meets expectations however we do this on the saved copy rather than on the actual signal context passed in. This breaks validation of EXTRA_CONTEXT since we attempt to validate the ABI requirement that the additional space supplied is immediately after the termination record in the standard context which will not be the case after it has been copied to another location. Fix this by doing the validation before we copy. Note that nothing actually looks inside the EXTRA_CONTEXT at present.

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:
