Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-amd64-amd64-pair        3 host-install/src_host(3) broken REGR. vs. 94070
 test-amd64-amd64-migrupgrade 4 host-install/dst_host(4) broken REGR. vs. 94070
 test-amd64-i386-xl-qemuu-winxpsp3-vcpus1 19 guest-destroy fail REGR. vs. 94070

Regressions which are regarded as allowable (not blocking):

commit 4f6aea066fe2cf3bf4929d6dac1e558071566f73
Author: Jan Beulich <jbeulich@xxxxxxxx>
Date:   Fri May 13 18:15:34 2016 +0100

    x86: reduce code size of struct cpu_info member accesses
    
    Instead of addressing these fields via the base of the stack (which
    uniformly requires 4-byte displacements), address them from the end
    (which for everything other than guest_cpu_user_regs requires just
    1-byte ones). This yields a code size reduction somewhere between 8k
    and 12k in my builds.

    x86: use 32-bit loads for 32-bit PV guest state reload
    
    This is slightly more efficient than loading 64-bit quantities.

    x86: use optimal NOPs to fill the SMEP/SMAP placeholders
    
    Alternatives patching code picks the most suitable NOPs for the
    running system, so simply use it to replace the pre-populated ones.
    
    Use an arbitrary, always available feature to key off from, but
    hide this behind the new X86_FEATURE_ALWAYS.

    x86: suppress SMEP and SMAP while running 32-bit PV guest code
    
    Since such guests' kernel code runs in ring 1, their memory accesses,
    at the paging layer, are supervisor mode ones, and hence subject to
    SMAP/SMEP checks. Such guests cannot be expected to be aware of those
    two features though (and so far we also don't expose the respective
    feature flags), and hence may suffer page faults they cannot deal with.
    
    While the placement of the re-enabling slightly weakens the intended
    protection, it was selected such that 64-bit paths would remain
    unaffected where possible. At the expense of a further performance hit
    the re-enabling could be put right next to the CLACs.
    
    Note that this introduces a number of extra TLB flushes - CR4.SMEP
    transitioning from 0 to 1 always causes a flush, and it transitioning
    from 1 to 0 may also do.
