tty: delete non-required instances of include

2014-01-08T01:05:21Z

None of these files are actually using any __init type directives and hence don't need to include . Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next. Signed-off-by: Paul Gortmaker Signed-off-by: Greg Kroah-Hartman

tty: Halve flip buffer GFP_ATOMIC memory consumption

2013-12-09T19:09:24Z

tty flip buffers use GFP_ATOMIC allocations for received data which is to be processed by the line discipline. For each byte received, an extra byte is used to indicate the error status of that byte. Instead, if the received data is error-free, encode the entire buffer without status bytes. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Fix stale tty_buffer_flush() comment

2013-12-09T01:10:26Z

Commit d7a68be4f265be10e24be931c257af30ca55566b, 'tty: Only perform flip buffer flush from tty_buffer_flush()', removed buffer flushing from flush_to_ldisc(). Fix function header comment which describes the former behavior. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

staging/fwserial: Rip out rx buffering

tty: Remove tty_prepare_flip_string_flags()

2013-12-09T00:57:38Z

There is no in-tree user of tty_prepare_flip_string_flags(); remove. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Rename tty buffer memory_used field

2013-12-09T00:57:38Z

Trim up the memory_used field name to mem_used. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Enable configurable tty flip buffer limit

2013-12-09T00:57:38Z

Allow driver to configure its maximum flip buffer memory consumption/limit. This is necessary for very-high speed line rates (in excess of 10MB/sec) because the flip buffers can be saturated before the line discipline has a chance to throttle the input.

tty: Remove private constant from global namespace

2013-07-23T23:47:10Z

TTY_BUFFER_PAGE is only used within drivers/tty/tty_buffer.c; relocate to that file scope. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Fix unsafe vt paste_selection()

2013-07-23T23:47:10Z

Convert the tty_buffer_flush() exclusion mechanism to a public interface - tty_buffer_lock/unlock_exclusive() - and use the interface to safely write the paste selection to the line discipline. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman

tty: Merge __tty_flush_buffer() into lone call site

2013-07-23T23:47:09Z

__tty_flush_buffer() is now only called by tty_flush_buffer(); merge functions. Signed-off-by: Peter Hurley Signed-off-by: Greg Kroah-Hartman
