MIPS: Build fix - include into all smp_processor_id() users.

2009-06-24T17:34:39Z

Some of the were relying into smp.h being dragged in by another header which of course is fragile. uses smp_processor_id() only in macros and including smp.h there leads to an include loop, so don't change cpu-info.h. Signed-off-by: Ralf Baechle

kgdb, x86, arm, mips, powerpc: ignore user space single stepping

2008-09-26T15:36:41Z

On the x86 arch, user space single step exceptions should be ignored if they occur in the kernel space, such as ptrace stepping through a system call. First check if it is kgdb that is executing a single step, then ensure it is not an accidental traversal into the user space, while in kgdb, any other time the TIF_SINGLESTEP is set, kgdb should ignore the exception. On x86, arm, mips and powerpc, the kgdb_contthread usage was inconsistent with the way single stepping is implemented in the kgdb core. The arch specific stub should always set the kgdb_cpu_doing_single_step correctly if it is single stepping. This allows kgdb to correctly process an instruction steps if ptrace happens to be requesting an instruction step over a system call. Signed-off-by: Jason Wessel

[MIPS] kgdb: Do not call fixup_exception

2008-08-26T08:10:26Z

kgdb_mips_notify is called on IBE/DBE/FPE/BP/TRAP/RI exception. None of them need fixup. And doing fixup for a breakpoint exception will confuse gdb. Signed-off-by: Atsushi Nemoto Signed-off-by: Ralf Baechle

[MIPS] kgdb: add arch support for the kernel's kgdb core

2008-07-30T20:54:42Z

The new kgdb architecture specific handler registers and unregisters dynamically for exceptions depending on when you configure a kgdb I/O driver. Aside from initializing the exceptions earlier in the boot process, kgdb should have no impact on a device when it is compiled in so long as an I/O module is not configured for use. There have been quite a number of contributors during the existence of this patch (see arch/mips/kernel/kgdb.c). Most recently Jason re-wrote the mips kgdb logic to use the die notification handlers.
