Subject: [PATCH 0/7] powerpc/mm: refactor vDSO mapping code
Date: Tue, 25 Oct 2016 18:50:59 +0300	[thread overview]
Message-ID: <20161025155106.29946-1-dsafonov@virtuozzo.com> (raw)

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
