From 0671c5b84e9e0a6d42d22da9b5d093787ac1c5f3 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 2 Oct 2019 18:59:49 +0000 Subject: MIPS: Wire up clone3 syscall Wire up the new clone3 syscall for MIPS, using save_static_function() to generate a wrapper that saves registers $s0-$s7 prior to invoking the generic sys_clone3 function just like we do for plain old clone. Tested atop 64r6el_defconfig using o32, n32 & n64 builds of the simple test program from: https://lore.kernel.org/lkml/20190716130631.tohj4ub54md25dys@brauner.io/ Signed-off-by: Paul Burton Cc: Christian Brauner Acked-by: Christian Brauner Cc: linux-mips@vger.kernel.org --- arch/mips/kernel/syscall.c | 1 + 1 file changed, 1 insertion(+) (limited to 'arch/mips/kernel/syscall.c') diff --git a/arch/mips/kernel/syscall.c b/arch/mips/kernel/syscall.c index b0e25e913bdb..3f16f3823031 100644 --- a/arch/mips/kernel/syscall.c +++ b/arch/mips/kernel/syscall.c @@ -80,6 +80,7 @@ SYSCALL_DEFINE6(mips_mmap2, unsigned long, addr, unsigned long, len, save_static_function(sys_fork); save_static_function(sys_clone); +save_static_function(sys_clone3); SYSCALL_DEFINE1(set_thread_area, unsigned long, addr) { -- cgit
