Hi, At long *long* last a respin of the patches that clean up pmd_get_atomic() and i386-PAE. I'd nearly forgotten why I did this, but the old posting gave clue that patch #7 was the whole purpose of me doing these patches. Having carried these patches for at least 2 years, they recently hit a rebase bump against the mg-lru patches, which is what prompted this repost. Linus' comment about try_cmpxchg64() (and Uros before him) made me redo those patches (see patch #10) which resulted in pxx_xchg64(). This in turn led to killing off set_64bit(). The robot doesn't hate on these patches and they boot in kvm (because who still has i386 hardware).
