2008-10-13tty: simplify ktermios allocationAlan Cox
Copy the simplification from the pty unix98 special case to the generic one. This allows us to kill off driver->termios_locked entirely which is nice.

2008-10-13serial: allow 8250 to be used on sparcDavid Miller
This requires three changes: 1) Remove !SPARC restriction in Kconfig. 2) Move Sparc specific serial drivers before 8250, so that serial console devices don't change names on us, even if 8250 finds devices. 3) Since the Sparc specific serial drivers try to use the same major/minor device namespace as 8250, some coordination is necessary. Use the sunserial_*() layer routines to allocate minor number space within TTY_MAJOR when CONFIG_SPARC. This has no effect on other platforms.

2008-09-23atmel_serial: update the powersave handler to match serial coreAnti Sullin
This problem seems to be unnoticed so far: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=b3b708fa2780cd2b5d8266a8f0c3a1cab364d4d2 has changed the serial core behavior to not to suspend the port if the device is enabled as a wakeup source. If the AT91 system goes to slow clock mode, the port should be suspended always and the clocks should be switched off. The patch attached updates the atmel_serial driver to match the changes in serial core. Also, the interrupts are disabled when the clock is disabled. If we disable the clock with interrupts enabled, an interrupt may get stuck. If this is the DBGU interrupt, this blocks the OR logic at system controller and thus all other sysc interrupts.

2008-09-028250: improve workaround for UARTs that don't re-assert THRE correctlyWill Newton
Recent changes to tighten the check for UARTs that don't correctly re-assert THRE (01c194d9278efc15d4785ff205643e9c0bdcef53: "serial 8250: tighten test for using backup timer") caused problems when such a UART was opened for the second time - the bug could only successfully be detected at first initialization. For users of this version of this particular UART IP it is fatal. This patch stores the information about the bug in the bugs field of the port structure when the port is first started up so subsequent opens can check this bit even if the test for the bug fails. David Brownell: "My own exposure to this is that the UART on DaVinci hardware, which TI allegedly derived from its original 16550 logic, has periodically gone from working to unusable with the mainline 8250.c ... and back and forth a bunch. Currently it's "unusable", a regression from some previous versions. With this patch from Will, it's usable."
