We can ignore this for all the other kernels. Apart than that, the patch makes sense, therefore: applied to jammy/linux. Thanks, -Andrea

BugLink: https://bugs.launchpad.net/bugs/1967750 Update configs after applying AMX patchset. Enforce STRICT_SIGALTSTACK_SIZE as off, because: CONFIG_STRICT_SIGALTSTACK_SIZE is intend for enforcing strict checking of the sigaltstack size against the *real size of the FPU frame*, enabling it is risky since it may lead to the broken of legacy applications which already allocate a too small sigaltstack but can still work because they never get a signal delivered.
