IMHO this is a macro problem and we locally have this fix running:
https://github.com/glycoknob/builder/commit/4dbb2911ec890ff698e1df6cad86584b5628f99f

please test and report, we can send it if it's useful for others too.

Hi,

it's already fixed in the Kernel since June:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=30b11ee9ae23d78de66b9ae315880af17a64ba83
- But it's not in Kernel 3.18

Maybe it's better to just raise the Kernel version? Or should I submit
the patch to the list?

regards
Martin

Doesn't seem like 3.18 has something that 4.0 or 4.1 have, although it
might be interesting for proper UML support in CC.

I would just submit the patch as it is, to have it included in master ASAP.
Although the migration to any of the 4.x kernels does seem
straightforward...

It's up to you =)

Hi Bastian,

I have patched, compiled correctly, and working alright! =)

You should really send that patch upstream!

[OpenWrt-Devel] UML not working in master

2015-09-25 Thread Javier Domingo Cansino 
Hi,

I wanted to setup for some tests an environment running uml, and I found
it's not compiling on master with default config. The error seems similar
to a previous one I found in the bug tracker.

https://dev.openwrt.org/ticket/870

Is anyone actually maintaining UML or managed to make it work? What other
ways of testing without a device would you propose? I had thought on a qemu
kvm x86 image if there is no other way, but the UML seemed like the most
straightforward to be able to develop in the local machine.

Cheers!
