This is a clean up patch. 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. [1] http://www.spinics.net/lists/arm-kernel/msg523188.html Changes since v2: - include 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 __read_mostly Jisheng Zhang (4): arm64: vdso: add __init section marker to alloc_vectors_page arm64: vdso: constify vm_special_mapping used for aarch32 vectors page arm64: kaslr: Fix incorrect placement of __initdata and __read_mostly arm64: apply __ro_after_init to some objects arch/arm64/kernel/cpu_ops.c | 2 +- arch/arm64/kernel/kaslr.c | 4 ++-- arch/arm64/kernel/vdso.c | 32 ++++++++++++++++---------------- arch/arm64/mm/dma-mapping.c | 2 +- arch/arm64/mm/init.c | 4 ++-- arch/arm64/mm/mmu.c | 2 +- 6 files changed, 23 insertions(+), 23 deletions(-) -- 2.8.1
