mips: migrate core kernel file from module.h --> export.h

2011-10-31T23:30:56+00:00

These files are not modules, but were including module.h only for
EXPORT_SYMBOL and/or THIS_MODULE.  Now that we have the lightweight
export.h, use it in these kinds of cases.

MIPS: Eleminate filenames from comments

2009-08-03T16:52:40+00:00

They tend to get not updated when files are moved around or copied and
lack any obvious use.  While at it zap some only too obvious comments and
as per Shinya's suggestion, add a copyright header to extable.c.

proc: add /proc/*/stack

2009-01-05T09:27:44+00:00

/proc/*/stack adds the ability to query a task's stack trace. It is more
useful than /proc/*/wchan as it provides full stack trace instead of single
depth. Example output:

	$ cat /proc/self/stack
	[] save_stack_trace_tsk+0x17/0x35
	[] proc_pid_stack+0x4a/0x76
	[] proc_single_show+0x4a/0x5e
	[] seq_read+0xf3/0x29f
	[] vfs_read+0x6d/0x91
	[] sys_read+0x3b/0x60
	[] syscall_call+0x7/0xb
	[] 0xffffffff

simplify the stacktrace code

2007-05-08T18:14:58+00:00

Simplify the stacktrace code:

 - remove the unused task argument to save_stack_trace, it's always
   current
 - remove the all_contexts flag, it's alwasy 0

[MIPS] save_context_stack fix

2006-10-19T16:55:13+00:00

CONFIG_KALLSYMS=n case is obviously wrong, though it is harmless since
CONFIG_KALLSYMS is always enabled with CONFIG_STACKTRACE for now.

[MIPS] Make unwind_stack() can dig into interrupted context

2006-10-01T22:16:59+00:00

If the PC was ret_from_irq or ret_from_exception, there will be no
more normal stackframe.  Instead of stopping the unwinding, use PC and
RA saved by an exception handler to continue unwinding into the
interrupted context.  This also simplifies the CONFIG_STACKTRACE code.
