[TRIVIAL] ppc64 shmget() translation bugfix

[David Gibson]

Linus, please apply:

The 32->64 bit syscall translation layer on ppc64 incorrectly
sign-extends rather than zero-extending the second parameter to
shmget(), which should be a size_t.  This means that it is impossible
to shmget() more 2GB or more from a 32-bit process.
