Subject: Re: [PATCH 07/14] syscalls: add ARCH_COMPAT_SYSCALL_DEFINE()

Excerpts from Jason Baron's message of Wed Mar 17 04:46:42 +1100 2010:
<snip>
> +    SYSCALL_METADATA(syscall, compat_sys_##sname, x);    \
> +    asmlinkage long syscall(__SC_DECL##x(__VA_ARGS__))

I think that should be:
#define COMPAT_SYSCALL_DEFINEx(x, syscall, sname, ...)

To avoid breaking archs without compat syscalls.

Cheers,
