um: ensure `make ARCH=um mrproper` removes arch/$(SUBARCH)/include/generated/
In this workflow: $ make ARCH=um defconfig && make ARCH=um -j8 [snip] $ make ARCH=um mrproper [snip] $ make ARCH=um defconfig O=./build_um && make ARCH=um -j8 O=./build_um [snip] CC scripts/mod/empty.o In file included from ../include/linux/types.h:6, from ../include/linux/mod_devicetable.h:12, from ../scripts/mod/devicetable-offsets.c:3: ../include/uapi/linux/types.h:5:10: fatal error: asm/types.h: No such file or directory 5 | #include <asm/types.h> | ^~~~~~~~~~~~~ compilation terminated. make[2]: *** [../scripts/Makefile.build:100: scripts/mod/devicetable-offsets.s] Error 1 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [/home/iha/sdb/opensource/lkmp/linux-kselftest.git/Makefile:1140: prepare0] Error 2 make[1]: Leaving directory '/home/iha/sdb/opensource/lkmp/linux-kselftest.git/build_um' make: *** [Makefile:180: sub-make] Error 2 The cause of the error was because arch/$(SUBARCH)/include/generated files weren't properly cleaned by `make ARCH=um mrproper`.
