Hi Benjamin,

kernel test robot noticed the following build warnings:

If you fix the issue in a separate patch/commit (i.e. not just a new version of the same patch/commit), kindly add following tags

sparse warnings: (new ones prefixed by >>) command-line: note: in included file (through tools/include/nolibc/nolibc.h, tools/include/nolibc/stddef.h, arch/um/include/shared/user.h, builtin):
tools/include/nolibc/sys.h:109:29: sparse: sparse: Using plain integer as NULL pointer
unistd.h:70:30: sparse: sparse: Using plain integer as NULL pointer tools/include/nolibc/unistd.h:70:33: sparse: sparse: Using plain integer as NULL pointer
Do you intend to work on your UML with nolibc patches this cycle? If not I would fix these sparse warnings in the nolibc tree and also apply your nolibc patches.
We are not in a hurry for the UML part and while it shouldn't be too much work, I obviously didn't get around to it in the last week.
So, feel free to pull the patches in via your tree. Then I'll submit the UML part again in the next cycle.
