Sorry for the delay in this update. Changes from v1: * Improve the skip message along with the changelog massage (Suah Khan). * Simplify the feature support check (Suah Khan). === Cover Letter === A couple of test updates are included: * 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 now. 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. The series is available in this repository: git://github.com/intel/amx-linux.git selftest [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/x86/Kconfig#n2432 [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/admin-guide/kernel-parameters.txt#n5676 [3] 3aac3ebea08f ("x86/signal: Implement sigaltstack size validation") [4] 4b7ca609a33d ("x86/signal: Use fpu::__state_user_size for sigalt stack validation") Chang S.
