Dear maintainers,
Let me follow up on the last posting [5] with these two small changes: * Clean up unused code in the AMX test. * Fix the subsystem name in the patch1 subject.
Here is a summary of the included test code changes:
* With the STRICT_SIGALTSTACK_SIZE option [1,2], the kernel's altstack check becomes stringent. The x86 sigaltstack test is ignorant about this. Adjust the test. This check was established [3] to ensure every AMX task's altstack is sufficient (regardless of that option) [4].
* The AMX test wrongly fails on non-AMX machines. Fix the code to skip the test instead.
* It also has some unused code. Remove them where at this.
The series is available in this repository: git://github.com/intel/amx-linux.git selftest
Thanks, Chang
