[PATCH 39/67] tty: introduce wait_event_interruptible_tty
From: Arnd Bergmann <arnd(a)arndb.de> Calling wait_event_interruptible implicitly releases the BKL when it sleeps, but we need to do this explcitly when we have converted it to a mutex.

[PATCH 04/67] serial: add UART_CAP_EFR and UART_CAP_SLEEP flags to 16C950 UARTs definition
From: Yegor Yefremov <yegor_sub1(a)visionsystems.de> Adding UART_CAP_EFR and UART_CAP_SLEEP flags will enable sleep mode and automatic CTS flow control for 16C950 UARTs. It will also avoid capabilities detection warning like this: "ttyS0: detected caps 00000700 should be 00000100" Signed-off-by: Yegor Yefremov... 5 Aug 2010 19:10

[PATCH 38/67] cdc-acm: remove dead code
From: Arnd Bergmann <arnd(a)arndb.de> The wait_event_interruptible_timeout in acm_port_down is never reached. Remove it to avoid possible deadlocks with the big tty mutex if someone were to start using the blocking version of acm_port_down.

[PATCH 30/67] serial: Change the wait for carrier locking
From: Alan Cox <alan(a)linux.intel.com> We want to push the lock/unlock into the helper functions so that we can prepare to move to using the tty_port helper. The expansion initially comes out a bit ugly but its worth the temporary expansion IMHO just so we can produce a nice testable series of changes. Signed-o... 5 Aug 2010 19:10

[PATCH 29/67] tty: Move the vt_tty field from the vc_data into the standard tty_port
From: Alan Cox <alan(a)linux.intel.com> This takes all the tty references through the expected interface points so we can refcount them.

[PATCH 28/67] tty: Make vt's have a tty_port
From: Alan Cox <alan(a)linux.intel.com> The vt layer isn't safely handling reference counts to tty object on the input side. Add a tty port structure to the vt layer in order to implement this using the standard helpers.

[PATCH 10/67] tty: remove remaining Hayes ESP ioctls
As Jeff Dike pointed out, the Hayes ESP driver was removed in commit f53a2ade0bb9f2a81f473e6469155172a96b7c38, so these ioctl definitions should also be removed. This cleans up the remaining arch-specific locations of this ioctl value. Thanks to Arnd for pointing these out. Cc: Jeff Dike <jdike(a)addtoit.com> ... 5 Aug 2010 19:10

[PATCH 12/67] vt/console: try harder to print output when panicing
From: Jesse Barnes <jbarnes(a)virtuousgeek.org> Jesse's initial patch commit said: "At panic time (i.e. when oops_in_progress is set) we should try a bit harder to update the screen and make sure output gets to the VT, since some drivers are capable of flipping back to it. So make sure we try to unblank and u... 5 Aug 2010 19:10
