Kernel-internal prototypes, references to current_thread_info() and code hidden behind a CONFIG_HEXAGON_ARCH_VERSION switch are certainly not usable in userspace, so this should not reside in a uapi header. Move the code into an internal version of ptrace.h instead. Signed-off-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
