[Xen-devel] [PATCH 5/12] VTPM mini-os: mfn_is_ram check disable

[Matthew Fioravante <matthew.fioravante@xxxxxxxxxx>]

Currently when mapping io memory regions into a mini-os domain a check 
is performed to make sure the memory region really is io memory. While 
this is a good idea in practice, the code doing the check fails if you 
have over 4GB since there may be system memory mapped after the io 
memory mappings.
This patch disables the check and turns it into a stub. It is required 
for tpm passthrough to the vtpm manager domain.
