[ltt-dev] [PATCH 0/3] Support for user space rcu for ARM < v7

This patch makes the ARM support in user space rcu a bit more generic
by renaming the headers and adding a test case for the dmb
instruction.  On a arch that does not have dmb the generic fallback to
the compiler barrier appears to work fine.

This patch set was tested on ARMv5, ARMv6 and ARMv7.

Comments are welcome.

Thanks,
Jason.
