The following set of patches address some limitations on microcode loading.
First patch avoids a redundant microcode load on sibling thread if another HT sibling got updated.
Ashok Raj (3): x86/microcode/intel: Check microcode revision before updating sibling threads x86/microcode/intel: Perform a cache flush before ucode update. x86/microcode: Quiesce all threads before a microcode update.
