[Xen-devel] [PATCH v2 0/9] xen: Convert __page_to_mfn and __mfn_to_page to use typesafe MFN

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hi all,

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 becaue the rest
of the function use mfn_t.

So I think it is time to make __page_to_mfn and __mfn_to_page using typesafe
MFN.

The first 8 patches will convert of the code to use typesafe MFN, easing
the tree-wide conversion in patch 8.

Note that this was only build tested it on x86.

Cheers,
