I seem to recall udapl does some very bogus things with <asm/atomic.h>
and atomic operations in general.
The built-in atomics in gcc had some ia64 issues until gcc 4.1.1 so we
had no choice but to get down and do some bogus things. :^)
Turns out Redhat 5 removed asm/atomic.h to force users back to the
built-in atomics which is fine given that Redhat 5 provides gcc 4.1.1.
We will go back and revisit all the hacks. In the short term, for OFED
1.2, we may have to simply add another conditional in the build
(configure.in) to handle the Redhat 5 case.
James, do you have any input here?
