commit 8cd9500958d818e3deabdd0d4164ea6fe1623d7c
Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>

    xen/vsprintf: Introduce %*pb[l] for printing bitmaps
    The format identifier is consistent with Linux.  The code is adapted from
    bitmap_scn{,list}printf() but cleaned up.
    This change allows all callers to avoid needing a secondary buffer to 
render a
    cpumask/nodemask into.

commit 3528426cb93948e440da947963bd8163f186ef67

    x86: don't setup legacy syscall vector when !CONFIG_PV
    The code snippet is to switch between SYS_DECS_trap_gate and
    SYS_DESC_irq_gate depending on whether XPTI is used. When PV is
    disabled there is no need to switch.

    x86: stub out PV only code in do_debug
    When PV is disabled those symbols won't be available. It is impossible
    for Xen to hit #DB there.

    x86: connect guest creation with CONFIG_PV
    This is a bit more complicated than the HVM case because system
    domains have PV guest type. Leave them like that.
