commit cf4b30dca0ad73e87802df83c5297abee9960c22
Author: George Dunlap <george.dunlap@xxxxxxxxxx>

    x86/mm: Add debug code to detect illegal page_lock and put_page_type 
ordering
    
    The fix for XSA-242 depends on the same cpu never calling
    _put_page_type() while holding a page_lock() for that page; doing so
    may cause a deadlock under the right conditions.
    
    Furthermore, even before that, there was never any discipline for the
    order in which page locks are grabbed; if there are any paths that
    grab the locks for two different pages at once, we risk creating the
    conditions for a deadlock to occur.
    
    These are believed to be safe, because it is believed that:
    1. No hypervisor paths ever lock two pages at once, and
    2. We never call _put_page_type() on a page while holding its page lock.
    
    Add a check to debug builds to catch any violations of these
    assumpitons.

commit df1e4c6e7f8892e950433ff33c215df0cd7b30f7

    make xen ocaml safe-strings compliant
    
    Xen built with ocaml 4.06 gives errors such as
    Error: This expression has type bytes but an expression was
            expected of type string
    as Byte and safe-strings which were introduced in 4.02 are the
    default in 4.06.
    This patch which is mostly by Richard W.M. Jones of Red Hat
    from https://bugzilla.redhat.com/show_bug.cgi?id=1526703
    fixes these issues.
    
    v2: drop tools/ocaml/libs/xc/xenctrl.ml from the patch as the
    affected code was removed by commit d933f1a53c06002351c1e36d40615e40bd4bf6af

    docs: clearify symlink usage in xen-pv-channel
    
    The previous version simply states that a symlink has to be created
    without telling where the symlink should point to.
