Re: [PATCH v3 1/3] audit: replace magic audit syscall class numbers with macros

Replace audit syscall class magic numbers with macros.
This required putting the macros into new header file
include/linux/auditscm.h since the syscall macros were included for both 64
bit and 32 bit in any compat code, causing redefinition warnings.
The ifndef/define didn't protect against redeclaration? Huh. Maybe
I'm not thinking about this correctly, or the arch specific code is
doing something wonky ...
Regardless, assuming that it is necessary, I would prefer if we called
it auditsc.h instead of auditscm.h; the latter makes me think of
sockets and not syscalls.
