Subject: [PATCH 0/6] x86/dumpstack: print entry regs when dumping the stack

Here's the next round of dumpstack-related patches.  This adds a
mechanism to identify any pt_regs on the stack so they can be printed in
the stack dump.

Josh Poimboeuf (6):
  x86/entry/unwind: create stack frames for saved interrupt registers
  x86/unwind: create stack frames for saved syscall registers
  x86/dumpstack: print stack identifier on its own line
  x86/dumpstack: print any pt_regs found on the stack
  x86/dumpstack: fix duplicate RIP address display in __show_regs()
  x86/dumpstack: print orig_ax in __show_regs()
