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 [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/x86/Kconfig#n2467 [2] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/admin-guide/kernel-parameters.txt#n6038 [3] 3aac3ebea08f ("x86/signal: Implement sigaltstack size validation") [4] 4b7ca609a33d ("x86/signal: Use fpu::__state_user_size for sigalt stack validation") [5] https://lore.kernel.org/lkml/20220711170330.27138-1-chang.seok.bae@xxxxxxxxx/ Chang S.
