I have put a version of KGDB for x86 RT kernels here:

The common_kgdb_cfi_.... stuff creates debug records for entry.S and
friends so that you can "bt" through them.  Apply in this order:
Ingo's patch
kgdb-ga-rt.patch
common_kgdb_cfi_annotations.patch

This is, more or less, the same kgdb that is in Andrew's mm tree changed
to fix the RT issues.


Hi, everybody

I found two bugs in kgdb-ga-rt patch.

The first one : if CONFIG_SMP is not set, we have a compile error
The second one : if CONFIG_KGDB is not set, we have a link error I send you a diff patch to correct this. I am not sure the last patch is correct, but it works.

The reported bugs are now rolled into the kgdb patch. Also, there is a new README.txt. I also included, in the kgdb patch, an updated gdb macro file (Documentation/i386/kgdb/gdbinit.hw) which has a per_cpu macro to:

	given a per_cpu structure name and the cpu number returns the
	address of that structure, properly typed.

I am also putting my current version of time_stamp_tool. This is the replacement for kgdb_ts() which I have removed from the kgdb patch. Still a little rough but it has promise of being arch independent.
