Regressions :-(

Tests which did not succeed and are blocking,
including tests which could not be run:
 build-amd64-oldkern           4 xen-build        fail in 17624 REGR. vs. 17611

Tests which are failing intermittently (not blocking):
 test-amd64-amd64-xl-qemut-win7-amd64  7 windows-install     fail pass in 17624

Regressions which are regarded as allowable (not blocking):
 test-amd64-amd64-xl-qemut-winxpsp3  7 windows-install fail in 17624 like 17601

Tests which did not succeed, but are not blocking:

commit e5b9f23485aa3709bec753badbcb989fde390925

    tools: Retry blktap2 tapdisk message on interrupt.
    
    Re-start blktap2 IPC select call on interrupt.
    
    We hunted this miserable bug for a long time.
    
    The teardown of a blktap2 tapdisk instance is being carried out
    inconsistently up to and including the 4.2.1 release.  The
    problem appears to be a classic 'Heisenbug' which disappears if a
    single function call is added to the tapdisk shutdown path.  It
    is likely this bug has been in existence for the life of the
    blktap2 code.
    
    Control messages to manipulate a tapdisk instance are sent over a
    UNIX domain socket.  A select call is used on both the read and
    write paths to wait on I/O and to set a timeout for the
    transmission and reception of the control plane messages.
    
    The existing code fails receipt or transmission of the control message
    on any type of error return from the select call.  The xl control
    process receives an interrupt while waiting in the select call which
    in turn causes an error return with SIGINT as the return code.
    
    This prematurely terminates the teardown of the tapdisk instance
    leaving it in various states of shutdown.  Since multiple messages
    are needed to implement a full teardown the tapdisk instance can be
    left in various states ranging from fully connected to only the minor
    being left allocated.
    
    The fix is straight forward.  Check the return code from the
    select call and re-try read or write of the control message if
    errno is sent to EINTR.  The problem manifests itself in the read
    path but there appears to be little reason to not add the fix to
    the write path as well.  Both paths appear to be cut-and-paste
    copies of each other.

    libxl: run libxl__arch_domain_create() much earlier.
    
    Among other things, arch_domain_create() sets the shadow(/hap/p2m)
    memory allocation, which must happen after vcpus are assigned (or the
    shadow op will fail) but before memory is allocated (or we might run
    out of p2m memory).
    
    libxl__build_pre(), which already sets similar things like maxmem,
    semes like a reasonable spot for it.  That needed a bit of plumbing to
    get the right datastructure from the caller.
    
    As a side-effect, the return code from libxl__arch_domain_create() is
    no longer ignored.
