Revision 5f630401f9e98bd062733b5bbef096dbf2158066 authored by Tiejun Chen on 22 August 2012, 16:10:20 UTC, committed by Benjamin Herrenschmidt on 24 August 2012, 10:26:06 UTC
For powerpc BooKE and e200, singlestep is handled on the critical/dbg exception stack. This causes current_thread_info() to fail for kgdb internal, so previously We work around this issue by copying the thread_info from the kernel stack before calling kgdb_handle_exception, and copying it back afterwards. But actually we don't do this properly. We should backup current_thread_info then restore that when exit.
