There are two errors when compile an out of tree kernel module
using sdk:
1. "In file included from ./include/linux/seqlock.h:36:0,
from ./include/linux/time.h:6,
from ./include/linux/stat.h:19,
from ./include/linux/module.h:10,
from kernel-module/char.c:1:
./include/linux/spinlock.h:60:10: fatal error: asm/mmiowb.h: No such
file or directory"
mmiowb.h is generated to ${B}/arch/${ARCH}/include/generated/asm/.
And there is only generated/ under ${B}/arch/${ARCH}/include/,
so I copy whole ${B}/arch/${ARCH}/include/ to $kerneldir/build/
in case of other files under generated/ is needed in the future.
2. "/bin/sh: scripts/mod/modpost: No such file or directory"
Copy above files or directory to $kerneldir/build/ fix the errors.
