I've just sent the 15th version of the series with changes according to the
feedback from Linus:
1. BUG_ON() in stackleak_erase() is safely eliminated;
2. Stack Clash detection (alloca() check) is completely dropped, since global
'-Wvla' should arrive soon. stackleak_check_alloca() for arm64 is dropped as
well in a separate commit.
This version is rebased onto Linus' tree.
Best regards,
Alexander
