  • db1c9dfa6   MN10300: die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs() ... Browse Code »

    die_if_no_fixup() shouldn't use get_user() as it doesn't call set_fs() to
    indicate that it wants to probe a kernel address. Instead it should use
    probe_kernel_read().

    This fixes the problem of gdb seeing SIGILL rather than SIGTRAP when hitting
    the KGDB special breakpoint upon SysRq+g being seen. The problem was that
    die_if_no_fixup() was failing to read the opcode of the instruction that caused
    the exception, and thus not fixing up the exception.

    This caused gdb to get a S04 response to the $? request in its remote protocol
    rather than S05 - which would then cause it to continue with $C04 rather than
    $c in an attempt to pass the signal onto the inferior process. The kernel,
    however, does not support $Cnn, and so objects by returning an E22 response,
    indicating an error. gdb does not expect this and prints:

    warning: Remote failure reply: E22

    and then returns to the gdb command prompt unable to continue.

  • 405f55712   headers: smp_lock.h redux ... Browse Code »

    * Remove smp_lock.h from files which don't need it (including some headers!)
    * Add smp_lock.h to files which do need it
    * Make smp_lock.h include conditional in hardirq.h
    It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

    This will make hardirq.h inclusion cheaper for every PREEMPT=n config
    (which includes allmodconfig/allyesconfig, BTW)

  • ad361c988   Remove multiple KERN_ prefixes from printk formats ... Browse Code »

    Commit 5fd29d6ccbc98884569d6f3105aeca70858b3e0f ("printk: clean up
    handling of log-levels and newlines") changed printk semantics. printk
    lines with multiple KERN_ prefixes are no longer emitted as
    before the patch.

    is now included in the output on each additional use.

    Remove all uses of multiple KERN_s in formats.

  • aa409e028   MN10300: Make the kernel jump into gdbstub on a BUG ... Browse Code »

    Make the kernel jump into gdbstub (if configured) on a BUG with the register
    set from the BUG rather than interpolating another illegal instruction and
    leaving gdbstub's idea of the process counter in unsupported_syscall() where
    the original BUG was detected.

    With this patch, gdbstub reports a SIGABRT to the compiler and reports the
    program counter at the original BUG, allowing the execution state at the time
    of the BUG to be examined with GDB.

  • b920de1b7   mn10300: add the MN10300/AM33 architecture to the kernel ... Browse Code »

    Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
    kernel.

    This patch also adds board support for the ASB2303 with the ASB2308 daughter
    board, and the ASB2305. The only processor supported is the MN103E010, which
    is an AM33v2 core plus on-chip devices.
