See PATCH 2/4 for the details. Comments welcome. Then it switches drivers to use them. First, to DEFINE_UART_PORT_TX_HELPER() in 3/4 and then DEFINE_UART_PORT_TX_HELPER_LIMITED() in 4/4. The diffstat of patches 3+4 is as follows: 26 files changed, 191 insertions(+), 823 deletions(-) which appears to be nice.
