[PATCH] kdump: Save trap information for later analysis
If we are faulting in kernel it is quite possible this will lead to a panic. Save trap number, cr2 (in case of page fault) and error_code in the current thread (these fields already exist for signal delivery but are not used here). This helps later kdump crash analyzing from user-space (a script has been submitted to dig this info out in gdb).
