Subject:    [PATCH 7/9] drop explicit long cases in generic syscall layer
From:       Mike Frysinger <vapier () gentoo ! org>

We don't need to normalize the arguments to the syscalls here as the
syscall func accepts any argument type.  Plus, the syscall stubs that
the library sets up already exports the right types that it needs so
value normalization happens there.
