Bug#679449: shared memory problem on armel

2013-02-07 Thread martinwguy
Mapping the same shared memory twice in one process is stupid, anyway. Just disable the test on armel and armhf. Correction: starting from ARMv7, this is supported. So the test can be enabled for armhf (and arm64). No, you have to test for the architecture being V7+, not for armhf. That

Ben, With Raspbian, we've done our best to maintain maximum compatibility with Debian and deliver to the Raspberry Pi community a rich Debian experience to a million+ new Linux users. As the decision for Armhf to support Armv7+ rather than Armv6 was made well before the Raspberry Pi existed
