Now that a VHE host uses tpidr_el2 for the cpu offset we no longer need KVM to save/restore tpidr_el1. Move this from the 'common' code into the non-vhe code. While we're at it, on VHE we don't need to save the ELR or SPSR as kernel_entry in entry.S will have pushed these onto the kernel stack, and will restore them from there. Move these to the non-vhe code as we need them to get back to the host. Finally remove the always-copy-tpidr we hid in the stage2 setup code, cpufeature's enable callback will do this for VHE, we only need KVM to do it for non-vhe. Add the copy into kvm-init instead.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
