uml: delete unused code
Get rid of a bunch of unused stuff - cpu_feature had no users linux_prog is little-used, so its declaration is moved to the user for easy deletion when the whole file goes away a long-unused debugging aid in helper.c is gone Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
