There is one other trivial patch I resent for the atomisp staging driver and a longer series for networking ioctls that I need to revalidate before submitting again. Sorry for the long delay before resending this. Once everyone is happy with the latest version, I would add it to the asm-generic tree for a 5.14 merge. Arnd --- Changes in v3: - fix whitespace as pointed out by Christoph Hellwig - minor build fixes - rebase to v5.13-rc1 Changes in v2: - address review comments from Christoph Hellwig - split syscall removal into a separate patch - replace __X32_COND_SYSCALL() with individual macros for x32 Link: https://lore.kernel.org/lkml/20201208150614.GA15765@infradead.org/ Arnd Bergmann (4): kexec: simplify compat_sys_kexec_load mm: simplify compat_sys_move_pages mm: simplify compat numa syscalls compat: remove some compat entry points arch/arm64/include/asm/unistd32.h | 12 +- arch/mips/kernel/syscalls/syscall_n32.tbl | 12 +- arch/mips/kernel/syscalls/syscall_o32.tbl | 12 +- arch/parisc/kernel/syscalls/syscall.tbl | 10 +- arch/powerpc/kernel/syscalls/syscall.tbl | 12 +- arch/s390/kernel/syscalls/syscall.tbl | 12 +- arch/sparc/kernel/syscalls/syscall.tbl | 12 +- arch/x86/entry/syscall_x32.c | 2 + arch/x86/entry/syscalls/syscall_32.tbl | 6 +- arch/x86/entry/syscalls/syscall_64.tbl | 4 +- include/linux/compat.h | 43 +---- include/linux/kexec.h | 2 - include/uapi/asm-generic/unistd.h | 12 +- kernel/kexec.c | 90 ++++------ kernel/sys_ni.c | 5 - mm/mempolicy.c | 195 +++++----------------- mm/migrate.c | 50 +++--- 17 files changed, 164 insertions(+), 327 deletions(-) -- 2.29.2 Cc: Christoph Hellwig <hch@infradead.org> Cc: linux-arch <linux-arch@vger.kernel.org> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Alexander Viro <viro@zeniv.linux.org.uk> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Andy Lutomirski <luto@kernel.org Cc: Borislav Petkov <bp@alien8.de> Cc: Brian Gerst <brgerst@gmail.com> Cc: Eric Biederman <ebiederm@xmission.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: "H.
