I have been working on converting Jerome's hmm_dummy driver and self tests into a stand-alone set of tests to be included in tools/testing/selftests/vm and came across these two bug fixes in the process. The tests aren't quite ready to be posted as a patch. I'm posting the fixes now since I thought they shouldn't wait. They should probably have a fixes line but with all the HMM

This is more or less simplified series of patches that bring power usage on my NV86 close to that of binary blob. Best regards, Maxim Levitsky

However just tweaking the define is not enough - we're not loading address of GOT into ebx before the call (on 32 bit ABIs) thus the call will be to nowhere. -- With best regards, Anton Korobeynikov Faculty of
