KASLR backport to LSK 4.4 review

Hi Ard,

The KASLR is backported to LSK v4.4 on git://git.linaro.org/kernel/linux-linaro-stable.git v4.4/topic/mm-kaslr

from v4.4.9 to 5dd612e parisc: Use generic extable search and sort .. Could you like help to review the backporting commits, especially on the 'Conflicts' commits: 44b9620 arm64: kvm: deal with kernel symbols outside of linear mapping 2894f32 arm64: prevent potential circular header dependencies in asm/bug.h d277954 Eliminate the .eh_frame sections from the aarch64 vmlinux and kernel modules 358e3c8 arm64: Use PoU cache instr for I/D coherency

Thanks Alex
