The arm and arm64 architectures allow a virtual address to be mapped using
a block descriptor (or huge page, as Linux calls it), and the function
mmu_set_ranges_sect() is made available for a test to do just that. But
virt_to_pte_phys() assumes that all virtual addresses are mapped with page
I was writing a quick test when I noticed that arm's implementation of
__virt_to_phys(), which ends up calling virt_to_pte_phys(), doesn't handle
block mappings and returns a bogus value. When fixing it I got confused
about mmu_get_pte() and get_pte(), so I (hopefully) improved things by
renaming
The function get_pte() from mmu.c returns a pointer to the PTE
associated with the requested virtual address, mapping the virtual
address in the process if it's not already mapped.
mmu_get_pte() returns a pointer to the PTE if and only if the virtual is
mapped in pgtable, otherwise returns NULL.
