Description Lukas Berk 2014-03-05 21:06:54 UTC 
As a progression from PR6961, there are times where having access to the current pt_regs is needed for backtracing, though not provided through any official mechanism.  It would be useful to provide synthetic pt_regs with values from the current registers.  One such case is attempting to backtrace though the current(invoking) module.

2014-04 commit 6ddf07acac et al seem to handle this.
