Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6:
sunsu: Use sunserial_console_termios() in sunsu_console_setup().
sunsu: Pass true 'ignore_line' to console match when RSC or LOM console.
serial: suncore: Fix RSC/LOM handling in sunserial_console_termios().
serial: suncore: Add 'ignore_line' argument to sunserial_console_match().
sunsu: Fix detection of SU ports which are RSC console or control.
sunsab: Do not set sunsab_reg.cons right before registering minors.
sparc64: Fix definition of VMEMMAP_SIZE.
