Hi,
This is an attempt to fix the build failures when building mn10300 with
allmodconfig. As I have never worked with arch files so I hope you will
point me to right direction to correct my mistakes in this attempt.
regards

Why not just add the memfd syscall to this arch? I thought someone had
already sent such a patch in a while ago.

Why has the linux-arm-kernel mailing list been copied for something
which clearly has nothing to do with ARM? Am I missing something
in this series?
(Or is there a competition on to see who can add as many entries in
the Cc without getting caught by any filtering? :) )

Yes, I intend to. But for now this will fix allmodconfig.

Then it is still not merged. :(
I will try to find that patch adding memfd syscall. And if i find it whom
shall I forward it to?

Please use a MOS_ (or MOS7720_) prefix instead and add it to all the
registers.
Thanks,

Some of the register names defined here are matching with registers
defined in other places. Like DCR is defined here and DCR is also
a register in mn10300 architecture. So when we are building this with
mn10300, build fails.
To avoid we rename all the registers.

Thanks Johan.
David,
This series works on next-20150618. But next-20150625 again fails in
allmodconfig of mn10300. I did a bisect and the first bad commit is:
db8786a2829c ("Merge remote-tracking branch 'dt-rh/for-next'").
And reverting it solved the problem. I will find out what was the exact
problem in that merge, but after I find out should i send a new series
or another patch?
regards
sudip

Even after applying this series allmodconfig of mn10300 is again failing
with error message like implicit declaration of function 'pci_iomap'.
And reverting b7d3282a245f ("net: via/Kconfig: replace USE_OF with OF_???")
fixes the problem and it builds again.

Gentle ping.
next-20150716 still fails allmodconfig of mn10300 with
am33_2.0-linux-gcc version 4.9.0

mn10300 doesn't use kprobe_ctlblk (or prev_kprobe). Nor does the core
kernel kprobes code. So these are arch-specific things and shouldn't
be referenced from include/linux/kprobes.h at all. I think - I didn't
look super-closely at it.
So an appropriate fix for this would be to move the references to
prev_kprobe/kprobe_ctlblk out of include/linux/kprobes.h and into
asm/kprobes.h. Presumably via include/asm-generic/kprobes.h in some
fashion.
Have you tested this patch on mn10300? Does kprobes actually work on
mn10300? Perhaps not, and the solution here is to disable kprobes on
that arch until someone fixes it all up.
Please resend any mn10300 fixes which you still have pending. Please
be a bit more sparing in the cc's when doing so ;)

No, this was not tested on board. :(
I tried my best to get a board but it seems board sellers in India have
not even heard the name of "mn10300". I tried contacting Koichi
Yasutake (one of the maintainer of mn10300) in hope of getting/buying
a board, but email of Koichi Yasutake is bouncing. I tried to contact
the company about one of their board and the following is their reply:
"As you say, linux runs on MN103E0700.
But MN103E0700 is now EOL, so we need not to maintenace linux."

Should i resend as it is or should i fix according to your suggestion?
or since this is arch specific changes and not tested on board so if you
want it can be dropped also.

yes, cc became a long list but it was also improper to send some part of
the series to few maintainer and other to some other maintainers.
