From: Arnd Bergmann <arnd@xxxxxxxx> Going through compat_alloc_user_space() to convert indirect system call arguments tends to add complexity compared to handling the native and compat logic in the same code. I have patches for all other uses of compat_alloc_user_space() as well, and would expect that we can subsequently remove the interface itself. 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 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 | 26 --- 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, 155 insertions(+), 319 deletions(-) Cc: Alexander Viro <viro@xxxxxxxxxxxxxxxxxx> Cc: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> Cc: Andy Lutomirski <luto@xxxxxxxxxx> Cc: Arnd Bergmann <arnd@xxxxxxxx> Cc: Borislav Petkov <bp@xxxxxxxxx> Cc: Brian Gerst <brgerst@xxxxxxxxx> Cc: Christoph Hellwig <hch@xxxxxxxxxxxxx> Cc: Eric Biederman <ebiederm@xxxxxxxxxxxx> Cc: Ingo Molnar <mingo@xxxxxxxxxx> Cc: "H .
