The new tty_port stuff is a bliss: no more per-driver mutex, no more counting for open(), well-separated initialization callbacks (I hope I got them right :-). But since I now use a lot of new tty_port stuff, I had to rebase the patch set on top of tty-next, so there's no point in cherry-picking anymore. So, in v6: - Converted the NMI tty driver to use tty_port helpers, per Alan Cox's suggestions; - In uart's poll_init callback fixed a race, spotted by Alan; - Use test_bit instead of touching port->flags directly; These patches can be found in the following repo (based on tty-next): git://git.infradead.org/users/cbou/linux-nmi-kdb.git master Old changelogs and rationale for these patches can be found here: v1-v5: http://lkml.org/lkml/2012/9/10/2 Thanks, -- arch/arm/Kconfig | 19 ++ arch/arm/common/vic.c | 28 +++ arch/arm/include/asm/hardware/vic.h | 2 + arch/arm/include/asm/kgdb.h | 8 + arch/arm/kernel/Makefile | 1 + arch/arm/kernel/entry-armv.S | 167 +------------ arch/arm/kernel/entry-header.S | 170 +++++++++++++ arch/arm/kernel/kgdb_fiq.c | 99 ++++++++ arch/arm/kernel/kgdb_fiq_entry.S | 87 +++++++ arch/arm/mach-versatile/Makefile | 1 + arch/arm/mach-versatile/kgdb_fiq.c | 31 +++ drivers/tty/serial/Kconfig | 19 ++ drivers/tty/serial/Makefile | 1 + drivers/tty/serial/amba-pl011.c | 66 ++++- drivers/tty/serial/kgdb_nmi.c | 391 ++++++++++++++++++++++++++++++ drivers/tty/serial/kgdboc.c | 16 ++ drivers/tty/serial/serial_core.c | 32 +++ include/linux/kdb.h | 29 ++- include/linux/kgdb.h | 34 +++ include/linux/serial_core.h | 2 + include/linux/tty_driver.h | 1 + kernel/debug/debug_core.c | 36 ++- kernel/debug/kdb/kdb_main.c | 29 +++ 23 files changed, 1076 insertions(+), 193 deletions(-)
