Subject[PATCH 0/7] powerpc/mm: refactor vDSO mapping code
Date
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.
Other changes - reduce exhaustive code duplication.
No visible to userspace changes expected.

Tested on qemu with buildroot rootfs.

Dmitry Safonov (7):
powerpc/vdso: unify return paths in setup_additional_pages
powerpc/vdso: remove unused params in vdso_do_func_patch{32,64}
powerpc/vdso: separate common code in vdso_common
powerpc/vdso: introduce init_vdso{32,64}_pagelist
powerpc/vdso: split map_vdso from arch_setup_additional_pages
powerpc/vdso: switch from legacy_special_mapping_vmops
mm: kill arch_mremap
