[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 7/7] xen: Convert __page_to_mfn and __mfn_to_page to use typesafe MFN
Most of the users of page_to_mfn and mfn_to_page are either overriding
the macros to make them work with mfn_t or use mfn_x/_mfn because the
rest of the function use mfn_t.
So make __page_to_mfn and __mfn_to_page return mfn_t by default.
Only reasonable clean-ups are done in this patch because it is
already quite big. So some of the files now override page_to_mfn and
mfn_to_page to avoid using mfn_t.
