Thomas Gleixner a8d6829044 x86: prevent C-states hang on AMD C1E enabled machines 
Impact: System hang when AMD C1E machines switch into C2/C3

AMD C1E enabled systems do not work with normal ACPI C-states 
even if the BIOS is advertising them. Limit the C-states to 
C1 for the ACPI processor idle code.
