Subject: [PATCH -tip] x86: ptrace.c ptrace_get_debugreg() should be static

This sparse warning:

arch/x86/kernel/ptrace.c:560:15: warning: symbol 'ptrace_get_debugreg' was not declared. Should it be static?

triggers because ptrace_get_debugreg() is global but is only used in a single .c file.
change ptrace_get_debugreg() to static to fix that - this also address the sparse warning.
