Correctly functioning 64-bit atomic shim layer. It's not what I would call effecient but it does have the advantage of being correct which is all I need right now. I added a regression test as well. git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@57 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c 2008-03-28 21:21:09 +03:00			`#include <sys/atomic.h>`

Update SPL to use new debug infrastructure. This means: - Replacing all BUG_ON()'s with proper ASSERT()'s - Using ENTRY,EXIT,GOTO, and RETURN macro to instument call paths git-svn-id: https://outreach.scidac.gov/svn/spl/trunk@78 7e1ea52c-4ff2-0310-8f11-9dd32ca42a1c 2008-04-21 21:29:47 +04:00			`#ifdef DEBUG_SUBSYSTEM`
