#     x86/ptrace: Mark expected switch fall-through
#     
#     Mark switch cases where we are expecting to fall through.
#     
#     This patch fixes the following warning (Building: allnoconfig i386):
#     
#     arch/x86/kernel/ptrace.c:202:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
#        if (unlikely(value == 0))
#           ^
