Any chance we can get this merged for 4.7? I need the updated syscall
table to be able to build GTK3 3.20+ on Debian/sh4.

Thanks,
Adrian

I've done basic checking that the added syscalls don't have
ABI/calling convention problems due to 64-bit args or similar. The
main ones in question were preadv2/pwritev2 and they have a clean
arch-generic mechanism for passing the 64-bit arg. So I think these
are fine to include in 4.8. I'm adding this patch and it will be in my
for-next branch soon and subsequently in my pull request for the
linux-sh tree.
