Comment 6 for bug 709711

We don't have the gcc builtins for atomic ops patch in the packaging either.

i grabbed the qemu-kvm source package to see which other patches we should look at:
- 1000-undo-earlier-static: seems useful for static builds; I think I send a static build fix upstream a while ago; don't think we really need this for now
- 2000-vmmouse-adapt-to-mouse-handler-changes: probably x86 specific
- arm-higher-initrd-load-address: you have that now
- arm-ignore-writes-of-perf-reg-cp15-with-crm-12: I think you have a more complete implementation
- caps-lock-key-up-event: probably useful for the SDL UI, should really go upstream
- Detect-and-use-GCC-atomic-builtins-for-locking: definitely missing in our tree
- larger_default_ram_size: bumps default RAM size, probably only applies to x86 vms, don't care

Yes, the GCC builtins stuff was sent upstream (by me) but two comments were made:
- ppc maintainer didn't want this merged as he said basically didn't trust the gcc builtins and thought it would be slower
- I think Paul Brook made the comment that the code which was being patched could go away entirely

I'm happy if you take a fresh look at this! :-)
