[ag-automation] [ANNOUNCE] RTDM for Linux-rt

I couldn't stop my curiosity to see it working. So, I downloaded the 
material from the repository and attacked linux-2.6.21-rc6-rt0 after 
enabling everything available in the "Real-time subsystem". BTW: 
Wouldn't it be less confusing to call this section differently? For 
example "RTDM subsystem" or similar? Sorry, just a first thought - there 
is so much real-time everywhere.

I then tried to build a new kernel. With a single exception, everything 
compiled without warning. The exception was switchtest that refused to 
build:

drivers/xenomai/testing/switchtest.c:1:27: error: nucleus/synch.h: No 
such file or directory
drivers/xenomai/testing/switchtest.c:2:28: error: nucleus/thread.h: No 
such file or directory
drivers/xenomai/testing/switchtest.c:5:32: error: asm/xenomai/fptest.h: 
No such file or directory

After disabling it, all sources could be compiled without any further 
problem. Linking xeno_rtdmtest.ko and xeno_16550A.ko, however, failed:
WARNING: "hrtimer_init_sleeper" 
[drivers/xenomai/testing/xeno_rtdmtest.ko] undefined!
WARNING: "hrtimer_init_sleeper" [drivers/xenomai/serial/xeno_16550A.ko] 
undefined!

I then disabled these two modules as well. The rest could be compiled 
and linked smoothly. The kernel was able to boot and the modules 
xeno_irqbench and xeno_can_virt could be loaded normally.

I then tried linux-2.6.20-rt8 - same situation as described above.

Will do some testing later. Anybody out there who would like to join the 
RTDM-Native Testing Group?
