Re: [Xen-devel] [PATCH v3] xen: arm: Support <32MB frametables

Hi Chris,

setup_frametable_mappings() rounds frametable_size up to a multiple

although it does allow the "contig" bit to be set in the PTEs.

Where the frametable is less than 32MB in size, instead round up
to a multiple of 2MB, not setting the "contig" bit in the PTEs.
