[PATCH] uml: x86_64 fixes
This fixes some x86_64 bugs - - maybe_map returns -1 on error instead of 0, which is interpreted as physical address 0 - removed an include of ipc.h, which isn't needed - fixed the calculation of signal frame location - the signal delivery code is now immune to the stack expansion check - added a missing include Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
