commit 068aab8579e79acdbe6b79868a065ac10beabbc5
Author: Reza Arbab <arbab@linux.vnet.ibm.com>

    powerpc/mm: Unstub radix__vmemmap_remove_mapping()
    
    Use remove_pagetable() and friends for radix vmemmap removal.
    
    We do not require the special-case handling of vmemmap done in the x86
    versions of these functions. This is because vmemmap_free() has already
    freed the mapped pages, and calls us with an aligned address range.
    
    So, add a few failsafe WARNs, but otherwise the code to remove physical
    mappings is already sufficient for vmemmap.
