mn10300 build fails

[Sudip Mukherjee <sudipm.mukherjee@gmail.com>]

Hi David,
I was trying to build mn10300 today and I got build failure.
I was following the steps of kbuild test robot <fengguang.wu@intel.com>
like:
wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross

and then I tried:
make.cross ARCH=mn10300 allmodconfig
make.cross ARCH=mn10300

again i tried with allyesconfig.
but in both cases build failed with:
error: invalid use of undefined type 'struct kprobe_ctlblk'

am i missing anything or is the build broken?

besides build failure it has got tons of build warning and
20 unimplemented syscalls.

previously also I tried to mail you and Koichi Yasutake asking about the
board I need, to start working with this architecture. But mails to
Koichi Yasutake bounced back and you never replied. :(

regards
sudip
