    SubjectRe: [patch 2/5] mm: remove vmalloc_to_pfn
    Sigh, missed nommu, sorry.

    ---

    vmalloc_to_pfn no longer has any callers left in the kernel. It was previously
    used so remap_pfn_range can be used on vmalloc memory, but is obsolete with
    the introduction of remap_vmalloc_range.
