Hi Anton,

FYI, there are new compile warnings show up in

tree:   git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git tty-next
head:   0c57dfcc6c1d037243c2f8fbf62eab3633326ec0
commit: 729043e82cdd403a131127254528afea8031ebab [36/40] kdb: Turn KGDB_KDB=n stubs into static inlines
config: cris-allyesconfig

Does the CRIS platform even support KDB?  Perhaps that is why this is
failing so badly?

Yes, I guess so.. Ignore it, or fix it by changing Kconfig to disable
KDB in the unsupported archs?

As we switched from empty macros to proper type-checking functions, the
new warnings most probably are all OK, but just to be sure...

Which are the new warnings? Do you have old build logs to compare?

And KDB is (and was) obviously broken for cris, should we disable it via
Kconfig?

Thanks,

OK.

> Which are the new warnings? Do you have old build logs to compare?

Here are the new warnings that show up in the tty-next HEAD. I'm not
sure it's worth looking into though (they are probably mostly side
effects created by the undefined macros errors). The x86 builds are
clean.

That would be great for me! Otherwise the build system will probably
see old/new problems popping up from time to time in this code.

I guess these are the new ones:

They're all OK. Before my patch, kgdb_register_repeat() was an empty
macro. But since we now do proper functions, the new warnings pop up.

Also, there's something interesting:

> > kernel/debug/kdb/kdb_main.c:2696:5: error: redefinition of 'kdb_register_repeat'

This means that we're trying to build KDB, but kdb.h don't see
CONFIG_KGDB_KDB.

More over, 'make ARCH=cris allyesconfig' producing .config with KGDB=n
and KGDB_KDB=n. And criss doesn't select HAVE_ARCH_KGDB.

I suspect there are some toolchain issues, or arch/cris/ does something
weird with the build system.

Also, "arch/cris/arch-v32/kernel/kgdb.c" -- it seems like it is its own
implementation of KGDB. :-) But it's CONFIG_ETRAX_KGDB...

So, I don't even think KGDB/KDB should be fixed anyhow, since cris doesn't
select HAVE_ARCH_KGDB, thus 'depends on !CRIS' doesn't make sense.

Thanks,
Anton.

It's true.

Ah silly me! I'm doing "make M=kernel/debug/kdb" which leads to all
the error/warnings. This can be fixed trivially. :)

Doing the regular 'make' triggers these errors:
