uml: console subsystem tidying
This does a lot of cleanup on the UML console system. This patch should be entirely non-functional. The tidying is as follows: header cleanups - the includes should be closer to minimal and complete all printks now have a severity lots of style fixes fd_close is restructured a little in order to reduce the nesting some functions were calling the os_* wrappers when they can call libc directly port_accept had a unnecessary variable it also tested a pid unecessarily before killing it some functions were made static xterm_free is gone, as it was identical to generic_free Signed-off-by: Jeff Dike <jdike@linux.intel.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>
