* syscall.c (known_scno): Do not check for native_scno field on platforms that support only one personality. --- native_scno was implemented for platforms with multiple personalities. On platforms that support only one personality, tcp->scno + NR_SYSCALL_BASE is already native.
native_scno is currently initialized in 4 syscallent.h files, but only
linux/i386/syscallent.h really have to use it, and other 3 of them
(linux/bfin/syscallent.h, linux/m68k/syscallent.h and
linux/microblaze/syscallent.h) don't really have to bother.
I suppose it's a result of cut-n-paste.
