Changes since v1, v2:
- use vdso64_pages only under CONFIG_PPC64 (32-bit build fix)
- remove arch_vma_name helper as not needed anymore,
simplify vdso_base pointer initializing in map_vdso()
Cleanup patches for vDSO on powerpc.
Originally, I wanted to add vDSO remapping on arm/aarch64 and
I decided to cleanup that part on powerpc.
I've add a hook for vm_ops for vDSO just like I did for x86,
which makes cross-arch arch_mremap hook no more needed.
Other changes - reduce exhaustive code duplication by
separating the common vdso code.
No visible to userspace changes expected.
Tested on qemu with buildroot rootfs.
