Subject: [PATCH 0/3] x86/MSR: Improve unhandled MSR access error message

From: Borislav Petkov <bp@...e.de>

Hi all,

here's a simple patchset improving the error message we're dumping when
an unchecked MSR is being done. Patch 3 has an example which explains
the improvement in detail.

Thanks.

Andy Lutomirski (1):
  x86/dumpstack: Honor supplied @regs arg

Borislav Petkov (2):
  printk: Make the printk*once() variants return a value
  x86/dumpstack: Add show_stack_regs() and use it
