4.14-stable review patch. If anyone has any objections, please let me know.

This has been fixed by another upstream commit:
7ee18d677989 ("x86/power: Make restore_processor_context() sane")

You can not directly apply it, will need backporting.

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?
