Linus Torvalds c9f016e72b A set of X86 fixes: 
- x2apic_disable() clears x2apic_state and x2apic_mode unconditionally,
     even when the state is X2APIC_ON_LOCKED, which prevents the kernel to
     disable it thereby creating inconsistent state.
 
     Reorder the logic so it actually works correctly
 
   - The XSTATE logic for handling LBR is incorrect as it assumes that
     XSAVES supports LBR when the CPU supports LBR. In fact both conditions
     need to be true. Otherwise the enablement of LBR in the IA32_XSS MSR
     fails and subsequently the machine crashes on the next XRSTORS
     operation because IA32_XSS is not initialized.
 
     Cache the XSTATE support bit during init and make the related functions
     use this cached information and the LBR CPU feature bit to cure this.
 
   - Cure a long standing bug in KASLR
 
     KASLR uses the full address space between PAGE_OFFSET and vaddr_end to
     randomize the starting points of the direct map, vmalloc and vmemmap
     regions.  It thereby limits the size of the direct map by using the
     installed memory size plus an extra configurable margin for hot-plug
     memory.  This limitation is done to gain more randomization space
     because otherwise only the holes between the direct map, vmalloc,
     vmemmap and vaddr_end would be usable for randomizing.
 
     The limited direct map size is not exposed to the rest of the kernel, so
     the memory hot-plug and resource management related code paths still
     operate under the assumption that the available address space can be
     determined with MAX_PHYSMEM_BITS.
 
     request_free_mem_region() allocates from (1 << MAX_PHYSMEM_BITS) - 1
     downwards.  That means the first allocation happens past the end of the
     direct map and if unlucky this address is in the vmalloc space, which
     causes high_memory to become greater than VMALLOC_START and consequently
     causes iounmap() to fail for valid ioremap addresses.
 
     Cure this by exposing the end of the direct map via PHYSMEM_END and use
     that for the memory hot-plug and resource management related places
     instead of relying on MAX_PHYSMEM_BITS. In the KASLR case PHYSMEM_END
     maps to a variable which is initialized by the KASLR initialization and
     otherwise it is based on MAX_PHYSMEM_BITS as before.
 
   - Prevent a data leak in mmio_read(). The TDVMCALL exposes the value of
     an initialized variabled on the stack to the VMM. The variable is only
     required as output value, so it does not have to exposed to the VMM in
     the first place.
 
   - Prevent an array overrun in the resource control code on systems with
     Sub-NUMA Clustering enabled because the code failed to adjust the index
     by the number of SNC nodes per L3 cache.
