[libvirt PATCH] scripts: Fix E741 that pycodesyle is pointing out during syntax-check
by Erik Skultety
With newer pycodestyle 2.6.0 (which is part of flake8-3.8.2) reports
the following pep violation during syntax-check:
../scripts/check-remote-protocol.py:95:9: E741 ambiguous variable name 'l'
for l in err.strip().split("\n")
On all the distros we test on, this hasn't occurred yet, but with the
future update of flake8 it likely would. The fix is easy, just name the
variable appropriately.
Signed-off-by: Erik Skultety <eskultet(a)redhat.com>

The weird thing is that E741 checking has been in pycodestyle since 2.1.0 [1],
we now have 2.5.0 and yet only 2.6.0 is complaining about it

[PATCH v2 1/3] libxl: Add 'permissive' option for PCI devices
by Marek Marczykowski-Górecki
From: Simon Gaiser <simon(a)invisiblethingslab.com>
By setting the permissive flag the Xen guest access to the PCI config space
is not filtered. This might be a security risk, but it's required for
some devices and the IOMMU and interrupt remapping should (mostly?)
contain it. Because of it (and that the attribute is Xen only), in an
example include "permissive='no'" - to not expose users copying from
documentation to extra risk.
Example usage:
<devices>
...
<hostdev mode='subsystem' type='pci' managed='yes' permissive='yes'>
<source>
<address domain='0x0000' bus='0x06' slot='0x02' function='0x0'/>
</source>
</hostdev>
</devices>

- update schema
- use virTristateBool
- add a test
- improve commit message
