    spinlock: fix build with older GCC

    Older GCC versions such as 4.3 cannot have initializers for the
    members of anonymous structures, so initialize .head_tail instead.

    Use a SPINLOCK_TICKET_INC define so this initializer is near the
    spinlock_tickets_t definition (in case the structure changes requiring
    changes to the initializer).

    x86emul: also put_fpu() on error paths

    fail_if() and generate_exception_if() could theoretically bypass the
    normal flow reaching put_fpu(), and not invoking it would leave the
    fpu_exception_callback pointer in place, allowing for the callback to
    be called at an unexpected time. Luckily the two
    generate_exception_if()-s that would actually trigger this are
    currently commented out, so this is not (yet) a (security) issue.

    xentrace: Implement cpu mask range parsing of human values (-c).

    Instead of just using -c 0x<some hex value> we can
    also use: -c <starting cpu>-<end cpu>, -c <cpu1>,<cpu2>, or a
    combination of them, or 'all' for all cpus.

    This new format can include just singular CPUs: -c <cpu1>,
    or ranges without an start or end (and xentrace will figure out
    the values), such as: -c -<cpu2> (which will include cpu0, cpu1,
    and cpu2) or -c <cpu2>- (which will include cpu2 and up to MAX_CPUS).

    That should make it easier to trace the right CPU if
    using this along with 'xl vcpu-list'.

    The code has been lifted from the Linux kernel, see file
    lib/bitmap.c, function __bitmap_parselist.

    To make the old behavior and the new function work, we check
    to see if the arguments have '0x' in them. If they do
    we use the old style parsing (limited to 32 CPUs). If that
    does not exist we use the new parsing.

    x86: rework paging_log_dirty_op to work with hvm guests

    When the caller of paging_log_dirty_op is a hvm guest Xen would choke when
    trying to copy the dirty bitmap to the guest because the paging lock is
    already held.

    Fix this by independently mapping each page of the guest bitmap as needed
    without the paging lock held.

    use ticket locks for spin locks

    Replace the byte locks with ticket locks.  Ticket locks are: a) fair;
    and b) peform better when contented since they spin without an atomic

    The lock is split into two ticket values: head and tail.  A locker
    acquires a ticket by (atomically) increasing tail and using the
    previous tail value.  A CPU holds the lock if its ticket == head.  The
    lock is released by increasing head.

    spin_lock_irq() and spin_lock_irqsave() now spin with irqs disabled
    (previously, they would spin with irqs enabled if possible).  This is
    required to prevent deadlocks when the irq handler tries to take the
    same lock with a higher ticket.

    Architectures need only provide arch_fetch_and_add() and two barriers:
    arch_lock_acquire_barrier() and arch_lock_release_barrier().
