Hi,
I'm seeing lots of this type of warning in 4.18-rc2 (maybe even before,
but this is on x86_32/i386, so maybe people aren't checking it so much?):
In file included from ../arch/x86/kernel/process_32.c:40:

I see around 300 of these.
Using: gcc (SUSE Linux) 8.1.1 20180523 [gcc-8-branch revision 260570]
Is there a patch for this?
thanks,
