Linus Torvalds 2af9b20dbb Misc fixes: 
- Fix a possible CPU hotplug deadlock bug caused by the new
    TSC synchronization code.
 
  - Fix a legacy PIC discovery bug that results in device troubles on
    affected systems, such as non-working keybards, etc.
 
  - Add a new Intel CPU model number to <asm/intel-family.h>.
