Fwd: [PATCH v2] uml: fix W=1 missing-include-dirs warnings

[Anton Ivanov]

Hi list,

If memory serves me right, the UML build in OpenWRT adds a uapi subdir. This patch adds it upstream and will probably break the openwrt build once it propagates.

Best Regards,

A.

Currently when using "W=1" with UML builds, there are over 700 warnings
like so:

CC arch/um/drivers/stderr_console.o
cc1: warning: ./arch/um/include/uapi: No such file or directory [-Wmissing-include-dirs]

but arch/um/ does not have include/uapi/ at all, so add that
subdir and put one Kbuild file into it (since git does not track
empty subdirs).

v2: use Option 4 from v1: add arch/um/include/uapi so that 'make' is
placated -- and just like all other arch's have.
