[PATCH 2/2] audit,x86: add x32_execve[at] to syscall classification
Treat x32 ABI variants of execve[at] the same as x86_64
variants.
Slightly speculative as the audit subsystem doesn't currently
work with x32 ABI syscalls. If and when audit+x32 does work,
this should correctly classify exec calls.
