For what it's worth, I was brave/daft enough to compile and run the testcase
with an -rc1 kernel and Linaro 11.09 filesystem on the quad A9 Versatile
Express:
root@dancing-fool:~# ./yad
mmap: addr 0x20000000
root@dancing-fool:~# ./yad
shm_open: File exists
mmap: addr 0x20000000
Looks like I'm missing the fireworks, despite the weirdy MAP_SHARED |
MAP_FIXED mmap flags.
