Sorry, I reposted the same patch inside the bunch of ones, hope it's not a
problem. However, I've seen some more problems which I didn't fix in the
patch:

This is left alone, but this way, the "285" syscall is not set at all, while
it should be sys_ni_syscall like for what I commented out (apart the ones at
the end).

While looking at the unistd.h code, I discovered another bug (for i386) - I'm
posting it here to avoid forgetting it:
/*
* user-visible error numbers are in the range -1 - -128: see
* <asm-i386/errno.h>
*/
But in include/asm-generic/errno.h, there is a problem:
#define EKEYREVOKED 128 /* Key has been revoked */
#define EKEYREJECTED 129 /* Key was rejected by service */
I.e. the range has changed...
I think that the max errno value should become a macro defined in errno.h.
