    x86: fix return value checks of set_guest_{machinecheck,nmi}_trapbounce
    
    Commit 0142064421 ("x86/traps: move set_guest_{machine,nmi}_trapbounce")
    converted the functions' return types from int to bool without also
    correcting the checks in assembly code: The ABI does not guarantee sub-
    32-bit return values to be promoted to 32 bits.
    
    Take the liberty and also adjust the number of spaces used in the compat
    code, such that both code sequences end up similar (they already are in
    the non-compat case).

    xen/schedule: Fix races in vcpu migration
    
    The current sequence to initiate vcpu migration is inefficent and 
error-prone:
    
    - The initiator sets VPF_migraging with the lock held, then drops the
      lock and calls vcpu_sleep_nosync(), which immediately grabs the lock
      again
    
    - A number of places unnecessarily check for v->pause_flags in between
      those two
    
    - Every call to vcpu_migrate() must be prefaced with
      vcpu_sleep_nosync() or introduce a race condition; this code
      duplication is error-prone
    
    - In the event that v->is_running is true at the beginning of
      vcpu_migrate(), it's almost certain that vcpu_migrate() will end up
      being called in context_switch() as well; we might as well simply
      let it run there and save the duplicated effort (which will be
      non-negligible).
    
    The result is that Credit1 has several races which result in runqueue
    <-> v->processor invariants being violated (triggering ASSERTs in
    debug builds and strange bugs in production builds).
    
    Instead, introduce vcpu_migrate_start() to initiate the process.
    vcpu_migrate_start() is called with the scheduling lock held.  It not
    only sets VPF_migrating, but also calls vcpu_sleep_nosync_locked()
    (which will automatically do nothing if there's nothing to do).
    
    Rename vcpu_migrate() to vcpu_migrate_finish().  Check for v->is_running and
    pause_flags & VPF_migrating at the top and return if appropriate.
    
    Then the way to initiate migration is consistently:
    
    * Grab lock
    * vcpu_migrate_start()
    * Release lock
    * vcpu_migrate_finish()

    xen: Introduce vcpu_sleep_nosync_locked()
    
    There are a lot of places which release a lock before calling
    vcpu_sleep_nosync(), which then just grabs the lock again.  This is
    not only a waste of time, but leads to more code duplication (since
    you have to copy-and-paste recipes rather than calling a unified
    function), which in turn leads to an increased chance of bugs.
    
    Introduce vcpu_sleep_nosync_locked(), which can be called if you
    already hold the schedule lock.
