Dirty hack to avoid assert failure. This has been discussed on xen-devel
but no solution has been found so far.
The box producing http://www-soc.lip6.fr/~bouyer/NetBSD-tests/xen/
is running with this patch; the printk has fired but the
hypervisor keeps running.

@The ASSERT(oc > 0) bug is still here, it's just that it doens't show up
any more on my test server. So add back the workaround.

@Update to 4.11.1nb1
PKGREVISION set to 1 on purpose, because this is not a stock 4.11.1 kernel
(it includes security patches).
4.11.1 includes all security patches up to XSA282.
Apply official patches for XSA284, XSA285, XSA287, XSA288, XSA290, XSA291,
XSA292, XSA293 and XSA294.
Other changes since 4.11.0 are mostly bugfixes, no new features.

1.1
log
@Add Xen 4.11.0 packages.
Note that there is a bug in 4.11 (also present in recent 4.6 and 4.8)
which causes an infrequent assert failure when running NetBSD PV guests.
The root cause has not been found, but a workaround is inclued which doesn't
seems to have ill effects. See xenkernel411/patches/patch-zz-bouyer
for details.
