Subject[PATCH v3 0/4] arm64: put objects into proper sections
This series tries to put some objects into proper sections.

patch1 puts alloc_vectors_page() into .init section. This is a clean up
patch2 constify vm_special_mapping used for aarch32 vectors page.
patch3 fix the incorrect placement of __initdata and __read_mostly
patch4 apply __ro_after_init to some objects

Previously I only want to mark vdso_pages, vdso_spec, vectors_page and
cpu_ops as __read_mostly for performance reason. Then inspired by
Kees's patch[1], I think __ro_after_init is better.


Changes since v2:
- include <linux/cache.h> for __ro_after_init, thank Mark's suggestions
- make vdso_spec[0].pages and vdso_spec[1].pages assignment style
consistent, thank Mark for pointing it out.

Changes since v1:
- use __ro_after_init instead of __read_mostly
- find more objects to be suitable for __ro_after_init
- add one more patch to fix the incorrect placement of __initdata and
