Revision 0671c5b84e9e0a6d42d22da9b5d093787ac1c5f3 authored by Paul Burton on 02 October 2019, 18:59:49 UTC, committed by Paul Burton on 02 October 2019, 21:06:41 UTC 
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:
