[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v4 00/16] xen: Convert page_to_mfn and mfn_to_page to use typesafe MFN
Hi all, This series is a rework of "xen: Convert __page_to_mfn and __mfn_to_page to use typesafe MFN" sent a couple of months ago (see [1]). In this new approach, the macros __page_to_mfn and __mfn_to_page are completely dropped. To avoid the last patch (#16) to be a huge patch some files are converted to use typesafe upfront. I have tried my best to push _mfn/mfn_x as down as possible in the callers. Some of them was not feasible without major rework, so I left them aside for now. Contribution to switch Xen code base to MFN typesafe are more than welcomed. Note that changes have only been build test it on x86 so far.
