Hi all,

Today's linux-next merge of the notifications tree got conflicts in:

arch/alpha/kernel/syscalls/syscall.tbl
arch/arm/tools/syscall.tbl
arch/arm64/include/asm/unistd.h
arch/arm64/include/asm/unistd32.h
arch/ia64/kernel/syscalls/syscall.tbl
arch/m68k/kernel/syscalls/syscall.tbl
arch/microblaze/kernel/syscalls/syscall.tbl
arch/mips/kernel/syscalls/syscall_n32.tbl
arch/mips/kernel/syscalls/syscall_n64.tbl
arch/mips/kernel/syscalls/syscall_o32.tbl
arch/parisc/kernel/syscalls/syscall.tbl
arch/powerpc/kernel/syscalls/syscall.tbl

arch/x86/entry/syscalls/syscall_64.tbl
arch/xtensa/kernel/syscalls/syscall.tbl
include/uapi/asm-generic/unistd.h

between commits:

b0a0c2615f6f ("epoll: wire up syscall epoll_pwait2")
450f68e2425e ("epoll: fix compat syscall wire up of epoll_pwait2")
ecb8ac8b1f14 ("mm/madvise: introduce process_madvise() syscall: an external memory hinting API")

from Linus' tree and commit:

4cd92d064cb0 ("watch_queue: Implement mount topology and attribute change notifications")

from the notifications tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

If this is not submitted to Linus during this merge window, please
either drop it from your linux-next included branch, or at least fix it
up wrt to the sate of Linus' tree.

Cheers,
Stephen Rothwell
