Hi,

so tglx found a couple of issues while we were talking about something
else and threw a couple of fixes over the wall, my way. Here's the
productized and tested result.

Thx.

Thomas Gleixner (7):
x86/mce/amd: Do proper cleanup on error paths
x86/mce/amd: Init thresholding machinery only on relevant vendors
x86/mce/amd: Protect a not-fully initialized bank from the
thresholding interrupt
x86/mce/amd: Sanitize thresholding device creation hotplug path
x86/mce/amd: Straighten CPU hotplug path
x86/mce/amd: Cleanup threshold device remove path
x86/mce/amd: Make threshold bank setting hotplug robust
