    Linus Torvalds authored
    Pull x86 updates and fixes from Thomas Gleixner:
    
     - Fix the (late) fallout from the vector management rework causing
       hlist corruption and irq descriptor reference leaks caused by a
       missing sanity check.
    
       The straight forward fix triggered another long standing issue to
       surface. The pre rework code hid the issue due to being way slower,
       but now the chance that user space sees an EBUSY error return when
       updating irq affinities is way higher, though quite a bunch of
       userspace tools do not handle it properly despite the fact that EBUSY
       could be returned for at least 10 years.
    
       It turned out that the EBUSY return can be avoided completely by
       utilizing the existing delayed affinity update mechanism for irq
       remapped scenarios as well. That's a bit more error handling in the
       kernel, but avoids fruitless fingerpointing discussions with tool
       developers.
    
     - Decouple PHYSICAL_MASK from AMD SME as its going to be required for
       the upcoming Intel memory encryption support as well.
    
     - Handle legacy device ACPI detection properly for newer platforms
    
     - Fix the wrong argument ordering in the vector allocation tracepoint
    
     - Simplify the IDT setup code for the APIC=n case
    
     - Use the proper string helpers in the MTRR code
    
     - Remove a stale unused VDSO source file
    
     - Convert the microcode update lock to a raw spinlock as its used in
       atomic context.
