1Make the devtmpfs options static. This works around an issue that is still
2under investigation.
3
4The toolchain assumes it can generate unaligned accesses for ARMv6+, as these
5cores can handle this, PROVIDED the bit is set in the CP15 control register.
6
7However, Linux sets this bit lazely (upon first trap), which does not work for
8kernel space code.
9
10There was a lengthy thread over this, the agreement was the kernel should not
11have non-aligned structures on stacks anyway.
12
13Forcing this structure to be aligned on the stack did not help, unsure why.
14This requires further investigation.
15
16This fixes a kernel failure if devtmpfs was enabled in the kernel config.

19Although this fixes first symptoms, needs further analysis to see if this is
20a long term fix. Is this contiguous memory? Does it fragment over time, thus
21only delay the actual error occurance, etc?
