Subject: linux-next: manual merge of the block tree with the asm-generic
tree
Hi all,
Today's linux-next merge of the block 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/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/xtensa/kernel/syscalls/syscall.tbl
include/uapi/asm-generic/unistd.h
between commits:
2fd0ebad27bc ("arch: Reserve map_shadow_stack() syscall number for all architectures")
from the asm-generic tree and commits:
9f6c532f59b2 ("futex: Add sys_futex_wake()")
cb8c4312afca ("futex: Add sys_futex_wait()")
0f4b5f972216 ("futex: Add sys_futex_requeue()")
from the block 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
