  Andrew has already fixed this and sent it to Linus.  And now I know to be
more careful when turning macros into inlines: a macro just sits there until
someone uses it while an inline function is always evaluated.

  Fix:

diff -puN include/asm-i386/ptrace.h~user_mode_vm-build-fix include/asm-i386/ptrace.h
