Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 test-armhf-armhf-libvirt-raw  3 host-install(3)        broken REGR. vs. 100844
 test-armhf-armhf-xl-arndale 15 guest-start/debian.repeat fail REGR. vs. 100844
 test-armhf-armhf-xl-vhd       9 debian-di-install        fail REGR. vs. 100844

Regressions which are regarded as allowable (not blocking):
 test-amd64-i386-xl-qemut-win7-amd64 16 guest-stop             fail like 100844

    arm/vm_event: get/set registers
    
    Add support for getting/setting registers through vm_event on ARM. Only
    TTB/CR/R0/R1, PC and CPSR are sent as part of a request and only PC is set
    as part of a response. The set of registers can be expanded in the future to
    include other registers as well if necessary.

    x86,arm: Change arch_livepatch_quiesce() declaration.
    
    On ARM we need an alternative VA region to poke in the
    hypervisor .text data. And since this is setup during runtime
    we may fail (it uses vmap so most likely error is ENOMEM).
    
    As such this error needs to be bubbled up and also abort
    the livepatching if it occurs.

    arm64/insn: introduce aarch64_insn_gen_{nop|branch_imm}() helper functions
    
    This is copied from Linux 4.7, and the initial commit
    that put this in is 5c5bf25d4f7a950382f94fc120a5818197b48fe9
    "arm64: introduce aarch64_insn_gen_{nop|branch_imm}() helper functions"
    
    This lays the groundwork for Livepatch to generate the
    trampoline to jump to the new replacement function.
    Also allows us to NOP the callsites.

    alternatives: x86 rename and change parameters on ARM
    
    On x86 we squash 'apply_alternatives' in to
    'alternative_instructions' (who was its sole user)
    and 'apply_alternatives_nocheck' to 'apply_alternatives'.
    
    On ARM we change the parameters for 'apply_alternatives'
    to be of 'const struct alt_instr *' instead of void pointer and
    size length.
    
    We also add 'const' and make the arguments be on the
    proper offset.

    x86/arm64: Expose the ALT_[ORIG|REPL]_PTR macros to header files.
    
    That way common code can use the same macro to access
    the most common attributes without much #ifdef.
    
    Take advantage of it right away in the livepatch code.
    
    Note: on ARM we use tabs to conform to the style of the file.

    livepatch: Bubble up sanity checks on Elf relocs
    
    The checks for SHT_REL[,A] ELF sanity checks does not need to
    be in the platform specific file and can be bubbled up
    in the platform agnostic file.
    
    This makes the ARM 32/64 implementation easier as the
    duplicate checks don't have to be in the platform specific files.

    xen/arm: alternative: Make it possible to patch outside of the hypervisor
    
    With livepatch the alternatives that should be patched are outside of
    the Xen hypervisor _start -> _end. The current code is assuming that
    only Xen could be patched and therefore will explode when a payload
    contains alternatives.
    
    Given that alt_instr contains a relative offset, the function
    __apply_alternatives could directly take in parameter the virtual
    address of the alt_instr set of the re-mapped region. So we can mandate
    the callers of __apply_alternatives to provide use with a region that has
    read-write access.
    
    The only caller that will patch directly the Xen binary is the function
    __apply_alternatives_multi_stop. The other caller apply_alternatives
    will work on the payload which will still have read-write access at that
    time.

    xen/arm: alternative: Clean-up __apply_alternatives
    
    This patch contains only renaming and comment update. There are no
    functional changes:
        - Don't mix _start and _stext, they both point to the same address
        but the former makes more sense (we are mapping the Xen binary, not
        only the text section).
        - s/text_mfn/xen_mfn/ and s/text_order/xen_order/ to make clear that
        we map the Xen binary.
        - Mention about inittext as alternative may patch this section.
        - Use 1U instead of 1 in shift

    xen/x86: Fix build with clang following c/s 4fa0105
    
    https://travis-ci.org/xen-project/xen/jobs/158494027#L2344
    
    Clang complains:
    
      emulate.c:2016:14: error: comparison of unsigned enum expression < 0
      is always false [-Werror,-Wtautological-compare]
          if ( seg < 0 || seg >= ARRAY_SIZE(hvmemul_ctxt->seg_reg) )
               ~~~ ^ ~
    
    Clang is wrong to raise a warning like this.  The signed-ness of an enum is
    implementation defined in C, and robust code must not assume the choices 
made
    by the compiler.
    
    In this case, dropping the < 0 check creates a latent bug which would result
    in an array underflow when compiled with a compiler which chooses a signed
    enum.
    
    Work around the bug by explicitly pulling seg into an unsigned integer, and
    only perform the upper bounds check.
    
    No functional change.
