Hi Greg,
After merging the tty.current tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
In file included from drivers/tty/serial/imx.c:42:0:
drivers/tty/serial/imx.c: In function 'imx_start_tx':
drivers/tty/serial/imx.c:570:27: error: request for member 'state' in something not a structure or union
if (uart_circ_empty(&port.state->xmit))

Caused by commit c557d392fbf5 ("serial: Test for no tx data on tx
restart"). That can't have been build tested :-(
I have used the tty.current tree from next-20140710 for today.

Sorry about that. I don't have a full cross-compiler setup for
build testing. Looks like that's something I'm going to have to add.

You forgot a "Reported-by:" tag.
I'll go add it...

see https://www.kernel.org/pub/tools/crosstool/
These are only good for building the kernel (no libc).
You don't necessarily need to build the whole kernel but often just
building the particular drivers is enough. Especially if they are
directly modified ...

It's not clear to me that Peter forgot it.
Someone else brought this up -- it seems to me that
Documentation/SubmittingPatches is a little too strong about needing
permission to use Reported-by:
If this patch fixes a problem reported by somebody else, consider adding a
Reported-by: tag to credit the reporter for their contribution. Please
note that this tag should not be added without the reporter's permission,
especially if the problem was not reported in a public forum. That said,
if we diligently credit our bug reporters, they will, hopefully, be
inspired to help us again in the future.
Sure, if a problem was reported privately, then we need to have permission
to use Reported-by, but if it was reported in a public forum, that should be
implicit permission (IMHO).
eh?

Yes, indeed.
Just to be clear, I hereby give my permission for the addition of
Reported-by: tags with my email address for anything I report
publically or privately. :-)

Why? Stephen pointed out the problem, in a public place, so I gave him
credit for it.

SubmittingPatches does not give you permission to do that,
but Stephen just did so.

Hi Stephen,
Thanks for the link. I had found Shuah Khan's slideshow pdf on cross-compiler
packages earlier and so have already started down that path.

Yeah, it was an oversight. I was rushing to get the patch done because
I was embarrassed about breaking the build.
The kbuild test robot actually notified me first though :)

I wish the Reported-by tag (and some others) was picked up by git send-email
automatically.

I agree.

Just an fyi,
The cross-compiler packages of the emdebian project in the unstable (aka, "sid")
distribution have broken dependencies.
So the instructions here
http://events.linuxfoundation.org/sites/events/files/slides/Shuah_Khan_cross_compile_linux.pdf
and here
http://linuxdriverproject.org/mediawiki/index.php/Cross-compiling_Linux_kernel_on_x86_64#Installation_Steps
are no longer applicable.

Peter Hurley
