Looking over the XenServer patchqueue:

These are all bugfixes, some that came from customer bugs:

e42e4d8c3e2c: tools/misc: xen-hvmcrash: Inject #DF instead of
overwriting RIP
42db2deb5e76: tools/libxs: Fix length check in xs_talkv()
ba709d514aac: x86/viridian: Clarify some viridian logging strings
d81dd3130351: x86/shutdown: change default reboot method preference
0d69635d27cb: tools/ocaml: Remove '-cc $(CC)' from OCAMLOPTFLAGS
8ffcf184affb: tools/ocaml: Fix OCaml libs rules
126293eae648: tools/ocaml: Drop the OCAMLOPTFLAG_G invocation
1965e9a93074: tools/ocaml: Fix the version embedded in META files
e58a2858d588: x86/boot: Preserve the value clobbered by the load-base
calculation

This is a diagnostic improvement, also from a customer bug:

2f413e22fa5e: x86/msr: add log messages to MSR state load error paths

These are a SIGPIPE bugfix which happen to also have a perf
improvement.  I cant remember if we discussed backporting them before. 
(Juergen/Anthony?)

42db2deb5e76: tools/libxs: Fix length check in xs_talkv()
e2a93bed8b9e: tools/libxs: Rework xs_talkv() to take xsd_sockmsg within
the iovec
f050c03ce2ad: tools/libxs: Rationalise the definition of struct xs_handle
046efe529e82: tools/libxs: Track whether we're using a socket or file
ebaeb0c64a6d: tools/libxs: Use writev()/sendmsg() instead of write()
a17b6db9b007: tools/libxs: Stop playing with SIGPIPE

These are from a livepatching snafu:

3a28da8f4daf: xen/livepatch: remove useless check for duplicated sections
8c81423038f1: xen/livepatch: drop load_addr Elf section field
86d09d16dd74: xen/livepatch: simplify and unify logic in prepare_payload()
fa49f4be413c: xen/livepatch: do Xen build-id check earlier
aa5a06d5d6ed: x86/alternatives: do not BUG during apply

where the buildid check is much too late.


And from looking at staging:

fa2d8318033e: x86/cpu-policy: Extend the guest max policy max leaf/subleaves

This fixes a real issue on older AMD systems.
