#     powerpc: Make virt_to_pfn() a static inline
#     
#     Making virt_to_pfn() a static inline taking a strongly typed
#     (const void *) makes the contract of a passing a pointer of that
#     type to the function explicit and exposes any misuse of the
#     macro virt_to_pfn() acting polymorphic and accepting many types
#     such as (void *), (unitptr_t) or (unsigned long) as arguments
#     without warnings.
#     
#     Move the virt_to_pfn() and related functions below the
#     declaration of __pa() so it compiles.
#     
#     For symmetry do the same with pfn_to_kaddr().
#     
#     As the file is included right into the linker file, we need
#     to surround the functions with ifndef __ASSEMBLY__ so we
#     don't cause compilation errors.
#     
#     The conversion moreover exposes the fact that pmd_page_vaddr()
#     was returning an unsigned long rather than a const void * as
#     could be expected, so all the sites defining pmd_page_vaddr()
#     had to be augmented as well.
#     
#     Finally the KVM code in book3s_64_mmu_hv.c was passing an
#     unsigned int to virt_to_phys() so fix that up with a cast so the
#     result compiles.
