Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty-2.6:
tty_port,usb-console: Fix usb serial console open/close regression
tty: cpm_uart: use resource_size()
tty_buffer: Fix distinct type warning
hvc_console: Fix race between hvc_close and hvc_remove
uartlite: Fix build on sparc.
tty: Take a 256 byte padding into account when buffering below sub-page units
Revert "tty: Add a new VT mode which is like VT_PROCESS but doesn't require a VT_RELDISP ioctl call"
