powerpc: wire up preadv2 and pwritev2 syscalls
Wire up preadv2/pwritev2 in the same way as preadv/pwritev. Fixes two build warnings on ppc64. mpe: Lightly tested with fio (slightly hacked to add the syscall wrappers): fio-4217 [009] .... 1304.635300: sys_preadv2(fd: 3, vec: 10025821de0, vlen: 1, pos_l: 6253000, pos_h: 0, flags: 1) fio-4217 [009] .... 1304.635474: sys_preadv2 -> 0x1000 Signed-off-by: Rui Salvaterra <rsalvaterra@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
