commit 6fd9b0361e2eb5a7f12bdd5cbf7e42c0d1937d26
Author: Jan Beulich <jbeulich@xxxxxxxx>
Date:   Fri Oct 11 09:31:16 2013 +0200

    x86: check for canonical address before doing page walks
    
    ... as there doesn't really exists any valid mapping for them.
    
    Particularly in the case of do_page_walk() this also avoids returning
    non-NULL for such invalid input.

    x86: use {rd,wr}{fs,gs}base when available
    
    ... as being intended to be faster than MSR reads/writes.
    
    In the case of emulate_privileged_op() also use these in favor of the
    cached (but possibly stale) addresses from arch.pv_vcpu. This allows
    entirely removing the code that was the subject of XSA-67.

    x86: add address validity check to guest_map_l1e()
    
    Just like for guest_get_eff_l1e() this prevents accessing as page
    tables (and with the wrong memory attribute) internal data inside Xen
    happening to be mapped with 1Gb pages.

commit 40d66baa46ca8a9ffa6df3e063a967d08ec92bcf
Author: Jan Beulich <jbeulich@xxxxxxxx>
Date:   Fri Oct 11 09:28:26 2013 +0200

    x86: correct LDT checks
    
    - MMUEXT_SET_LDT should behave as similarly to the LLDT instruction as
      possible: fail only if the base address is non-canonical
    - instead LDT descriptor accesses should fault if the descriptor
      address ends up being non-canonical (by ensuring this we at once
      avoid reading an entry from the mach-to-phys table and consider it a
      page table entry)
    - fault propagation on using LDT selectors must distinguish #PF and #GP
      (the latter must be raised for a non-canonical descriptor address,
      which also applies to several other uses of propagate_page_fault(),
      and hence the problem is being fixed there)
    - map_ldt_shadow_page() should properly wrap addresses for 32-bit VMs
    
    At once remove the odd invokation of map_ldt_shadow_page() from the
    MMUEXT_SET_LDT handler: There's nothing really telling us that the
    first LDT page is going to be preferred over others.
