Yazen, I've zapped everything from the handler unification onwards:

28e82d6f03b0 x86/mce: Save and use APEI corrected threshold limit
c8f4cea38959 x86/mce: Handle AMD threshold interrupt storms
5a92e88ffc49 x86/mce/amd: Define threshold restart function for banks
922300abd79d x86/mce/amd: Remove redundant reset_block()
9b92e18973ce x86/mce/amd: Support SMCA corrected error interrupt
fe02d3d00b06 x86/mce/amd: Enable interrupt vectors once per-CPU on SMCA systems
cf6f155e848b x86/mce: Unify AMD DFR handler with MCA Polling
53b3be0e79ef x86/mce: Unify AMD THR handler with MCA Polling

until this is properly sorted out, now this close to the merge window.

Thanks, Bert, for reporting!
