sh: unwinder: Use a special bug flag for unwinder traps. This simplifies the unwinder trap handling, dropping the use of the special trapa vector and simply piggybacking on top of the BUG support. A new BUGFLAG_UNWINDER is added for flagging the unwinder fault, before continuing on with regular BUG dispatch. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: Export unwind_stack() to satisfy modular oprofile. If the oprofile code is built as a module, unwind_stack() as used by the oprofile backtrace code is not available, causing build breakage. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: unwinder: Introduce UNWINDER_BUG() and UNWINDER_BUG_ON() We can't assume that if we execute the unwinder code and the unwinder was already running that it has faulted. Clearly two kernel threads can invoke the unwinder at the same time and may be running simultaneously. The previous approach used BUG() and BUG_ON() in the unwinder code to detect whether the unwinder was incapable of unwinding the stack, and that the next available unwinder should be used instead. A better approach is to explicitly invoke a trap handler to switch unwinders when the current unwinder cannot continue. Signed-off-by: Matt Fleming <matt@console-pimps.org>

sh: Allow multiple stack unwinders to be setup Provide an interface for registering stack unwinders, where each unwinder is given a rating that describes its accuracy and complexity. The more accurate an unwinder is, the more complex it is. If a the current stack unwinder faults, then the stack unwinder with the next highest accuracy will be used in its place (provided one is available). For example, this allows unwinders, such as the DWARF unwinder, to liberally sprinkle BUG()s to catch badly formed DWARF debug info.
