== Atomics == * Testing the libgcc fallback code with Nicholas's kernel patch - and then fixing my initialisation code to use init_array's (thanks Richard for the hint) * Tidying stuff up after a review of my patch by Richard - the sync.md is now smaller than the original before I started. * Discussing sync semantics with Michael Edwards - he's spotted that the gcc ARM sync routines need to move their final memory barrier for the compare-exchange case where the compare fails. * Looking at valgrind; it looks like it should be OK with the commpage changes; but it doesn't currently support ldrexd and strexd; there is a patch for it to do ARM mode but not thumb yet.
