2.6.30 added the new preadv/pwritev system calls. The following
architectures still haven't wired them up:
alpha, avr32, blackfin, cris, frv, h8300, m32r, xtensa
Can you maintainers please look into wiring these system calls up?

I've just added the following patch to the CRIS tree:
Adds sys_signalfd4, sys_eventfd2, sys_epoll_create1, sys_dup3,
sys_pipe2, sys_inotify_init1, sys_preadv, sys_pwritev
for both CRISv10 and CRISv32.

Care to send this and your current stack of patches upsteam before
2.6.30 is out?

Will do, I'll let it sit for a day in linux-next first.
