Subject: linux-next: manual merge of the notifications tree with Linus' tree
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/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/s390/kernel/syscalls/syscall.tbl
arch/sh/kernel/syscalls/syscall.tbl
arch/sparc/kernel/syscalls/syscall.tbl
arch/x86/entry/syscalls/syscall_32.tbl
arch/x86/entry/syscalls/syscall_64.tbl
arch/xtensa/kernel/syscalls/syscall.tbl
include/uapi/asm-generic/unistd.h
between commit:
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.

Cheers,
Stephen Rothwell
