It depends on the following commits:

5b06bbcfc2c6 x86/power: Fix some ordering bugs in __restore_processor_context()
090edbe23ff5 x86/power/64: Use struct desc_ptr for the IDT in struct saved_context
896c80bef4d3 x86/power/32: Move SYSENTER MSR restoration to fix_processor_context()
7ee18d677989 x86/power: Make restore_processor_context() sane

Greg, any objections to pulling them all in?
