    Subject[PATCH 0/6] KGDB/KDB/KGDBTS various regression fixes for 2.6.x -> 3.4
    This is a set of accumulated regression fixes which will go to to
    -stable once reviewed and merged to the mainline.

    The break down looks likes this for >= kernel x.x

    3.4: Fix an an Smatch warning that appeared in the 3.4 merge window
    3.0: Fix kgdb suite with SMP for all archs without HW single stepping
    2.6.36: Fix kgdb sw breakpoints with CONFIG_DEBUG_RODATA=y limitations on x86
    2.6.26: Fix oops on kgdb test suite with CONFIG_DEBUG_RODATA
    Fix kgdb suite with SMP for all archs with HW single stepping

    It is worth mentioning that fixing the kgdb test suite SMP problems
    has shown there are some stability problems with SMP ARM kernels and
    IPIs. These problems have been there for as long as ARM has had SMP
    support but there was no easy way to trigger the issue that causes a
    hard lockup. At some point I'll take a further look at this, but
    anyone is free to run the tests now that they work. :-)


    Jason Wessel (6):
    kdb: Fix smatch warning on dbg_io_ops->is_console
    kgdbts: Fix kernel oops with CONFIG_DEBUG_RODATA
    kgdbts: (1 of 2) fix single step awareness to work correctly with SMP
    kgdbts: (2 of 2) fix single step awareness to work correctly with SMP
    kgdb,debug_core: pass the breakpoint struct instead of address and memory
    x86,kgdb: Fix DEBUG_RODATA limitation using text_poke()
