Subject: [PATCH v2 0/2] arm64/sve: UAPI: Disentangle ptrace.h from sigcontext.h

This patch refactors the UAPI header definitions for the Arm SVE
extension to avoid multiple-definition problems when userspace mixes its
own sigcontext.h definitions with the kernel's ptrace.h (which is
apparently routine).

A common backend header is created to hold common definitions, suitably
namespaced.

The extra header guard in sve_context.h was considered redundant and is
now gone, so patch 1 (kbuild: install_headers.sh: Strip _UAPI from
#if-defined() guards) from the previous version of the series has been
dropeed.
