[PATCH v3 10/10] arm64: kernel: Add support for hibernate/suspend-to-disk.

[Pavel Machek]

Hi!

> Suspend borrows code from cpu_suspend() to write cpu state onto the stack,
> before calling swsusp_save() to save the memory image.

> Restore creates a set of temporary page tables, covering the kernel and the
> linear map, copies the restore code to a 'safe' page, then uses the copy to
> restore the memory image. It calls into cpu_resume(),
> and then follows the normal cpu_suspend() path back into the suspend code.
> 
> The implementation assumes that exactly the same kernel is booted on the
> same hardware, and that the kernel is loaded at the same physical address.

Actually... even additional includes should go after the #ifdef
guards.

Thanks,
