Merge tag 'tty-3.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Here are some tty/serial patches for 3.3-rc1

Big thing here is the movement of the 8250 serial drivers to their own
directory, now that the patch churn has calmed down.

Other than that, only minor stuff (omap patches were reverted as they
were found to be wrong), and another broken driver removed from the
system.

Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

+	  If you say Y here, it will be possible to use a serial port as the
+	  system console (the system console is the device which receives all
+	  kernel messages and warnings and which allows logins in single user
+	  mode). This could be useful if some terminal or printer is connected
+	  to that serial port.
+
+	  Even if you say Y here, the currently visible virtual console
+	  (/dev/tty0) will still be used as the system console by default, but
+	  you can alter that using a kernel command line option such as
+	  "console=ttyS1". (Try "man bootparam" or see the documentation of
+	  your boot loader (grub or lilo or loadlin) about how to pass options
+	  to the kernel at boot time.)
+
+	  If you don't have a VGA card installed and you say Y here, the
+	  kernel will automatically use the first serial line, /dev/ttyS0, as
+	  system console.
+
+	  You can set that using a kernel command line option such as
+	  "console=uart8250,io,0x3f8,9600n8"
+	  "console=uart8250,mmio,0xff5e0000,115200n8".

-	---help---
-	  If you say Y here, it will be possible to use a serial port as the
-	  system console (the system console is the device which receives all
-	  kernel messages and warnings and which allows logins in single user
-	  mode). This could be useful if some terminal or printer is connected
-	  to that serial port.
-
-	  Even if you say Y here, the currently visible virtual console
-	  (/dev/tty0) will still be used as the system console by default, but
-	  you can alter that using a kernel command line option such as
-	  "console=ttyS1". (Try "man bootparam" or see the documentation of
-	  your boot loader (grub or lilo or loadlin) about how to pass options
-	  to the kernel at boot time.)
-
-	  If you don't have a VGA card installed and you say Y here, the
-	  kernel will automatically use the first serial line, /dev/ttyS0, as
-	  system console.
-
-	  You can set that using a kernel command line option such as
-	  "console=uart8250,io,0x3f8,9600n8"
-	  "console=uart8250,mmio,0xff5e0000,115200n8".
-	  and it will switch to normal serial console when the corresponding 
-	  port is ready.
-	  "earlycon=uart8250,io,0x3f8,9600n8"
-	  "earlycon=uart8250,mmio,0xff5e0000,115200n8".
-	  it will not only setup early console.
-
-	  If unsure, say N.
