tty: move hvc drivers to drivers/tty/hvc/

2011-01-13T20:03:00Z

As requested by Arnd Bergmann, the hvc drivers are now moved to the drivers/tty/hvc/ directory. The virtio_console.c driver was also moved, as it required the hvc_console.h file to be able to be built, and it really is a hvc driver. Cc: Arnd Bergmann Signed-off-by: Greg Kroah-Hartman

hvsi: don't use flush_scheduled_work()

2010-12-24T14:59:07Z

flush_scheduled_work() is deprecated and scheduled to be removed. Directly cancel hp->writer and flush hp->handshaker instead. Signed-off-by: Tejun Heo Cc: Benjamin Herrenschmidt Cc: Paul Mackerras

Input: sysrq - drop tty argument form handle_sysrq()

2010-08-21T07:34:45Z

Sysrq operations do not accept tty argument anymore so no need to pass it to us.

hvc_console: use "*_console" nomenclature to avoid modpost warning.

2010-07-09T01:28:24Z

The use of "hvc_con_driver" as the name for a file-static "struct console" with a ".setup" field pointing to an __init function causes a modpost warning, since a non-initdata structure points to init code. Using "hvc_console" as the name triggers the hacky "*_console" workaround in modpost to silence the warning, and is the same thing that most of the other console drivers already do. I made the same change in hvsi.c since I happened to notice it was likely to suffer from the same problem. Signed-off-by: Chris Metcalf Signed-off-by: Benjamin Herrenschmidt

hvsi: fix messed up error checking getting state name

hvc_console: Remove tty->low_latency on pseries backends

2009-03-10T23:44:26Z

The hvcs and hvsi backends both set tty->low_latency to one, along with more or less scary comments regarding bugs or races that would happen if not doing so. However, they also both call tty_flip_buffer_push() in conexts where it's illegal to do so since some recent tty changes (or at least it may have been illegal always but it nows blows) when low_latency is set (ie, hard interrupt or with spinlock held and irqs disabled). This removes the setting for now to get them back to working condition, we'll have to address the races described in the comments separately if they are still an issue (some of this might have been fixed already).
