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
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 <paul.burton@mips.com> Cc: Christian Brauner <christian@brauner.io> Acked-by: Christian Brauner <christian.brauner@ubuntu.com> Cc: linux-mips@vger.kernel.org

* - get rid of pre-linked dev list, dynamic device allocation
* Paul Gortmaker (03/2002)
* - struct init cleanup, enable multiple ISA autoprobes.

* - fix sbni: s/device/net_device/
* Paul Gortmaker (06/98):
* - sort probes in a sane way, make sure all (safe) probes
* get run once & failed autoprobes don't autoprobe again.
