commit 11852c7bb070a18c3708b4c001772a23e7d4fc27
Author: Juergen Gross <jgross@xxxxxxxx>

    tools/xenstore: set maximum number of grants needed
    
    When running as a stubdom Xenstore should set the maximum number of
    grants needed via a call of xengnttab_set_max_grants(), as otherwise
    the number of domains which can be supported will be 128 only (the
    default number of grants supported by Mini-OS).
    
    We use one grant per domain so the theoretical maximum number is
    DOMID_FIRST_RESERVED.

    tools/cpuid: Plumb nested_virt down into xc_cpuid_apply_policy()
    
    Nested Virt is the final special case in legacy CPUID handling.  Pass the
    (poorly named) nested_hvm setting down into xc_cpuid_apply_policy() to break
    the semantic dependency on HVM_PARAM_NESTEDHVM.
    
    No functional change.

    libxc/bitops: increase potential size of bitmaps
    
    If the bitmap is used to represent domU pages, the amount of memory is
    limited to 8TB due to the 32bit value. Adjust the code to use 64bit
    values as input. All callers already use some form of 64bit as input,
    so no further adjustment is required.

    tools: Fix configure of upstream QEMU
    
    QEMU as recently switch its build system to use meson and the
    ./configure step with meson is more restrictive that the step used to
    be, most installation path wants to be within prefix, otherwise we
    have this error message:
    
        ERROR: The value of the 'datadir' option is '/usr/share/qemu-xen' which 
must be a subdir of the prefix '/usr/lib/xen'.
    
    In order to workaround the limitation, we will set prefix to the same
    one as for the rest of Xen installation, and set all the other paths.
    
    For reference, a thread in qemu-devel:
        "configure with datadir outside of --prefix fails with meson"
        
https://lore.kernel.org/qemu-devel/20200918133012.GH2024@xxxxxxxxxxxxxxxxxxxxxxx/t/
    
    And an issue in meson:
        "artificial limitation of directories (forced to be in prefix)"
