Merge branch 'for-linus-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rw/uml
Pull UML fixes from Richard Weinberger: "This patch set contains mostly fixes and cleanups. The UML tty driver uses now tty_port and is no longer broken like hell :-)" * 'for-linus-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rw/uml: um: Add arch/x86/um to MAINTAINERS um: pass siginfo to guest process um: fix ubd_file_size for read-only files um: pull interrupt_end() into userspace() um: split syscall_trace(), pass pt_regs to it um: switch UPT_SET_RETURN_VALUE and regs_return_value to pt_regs um: set BLK_CGROUP=y in defconfig um: remove count_lock um: fully use tty_port um: Remove dead code um: remove line_ioctl() TTY: um/line, use tty from tty_port TTY: um/line, add tty_port
