Hi, this series cleans up the Python sources, either static or generated, including also tests, to make them PEP 8 compliant; see https://www.python.org/dev/peps/pep-0008/ and tools like pep8. Almost all the issues reported by pep8 are fixed, reducing the issues from 3818 to 7. The changes should have no effect on the actual code, while it will help Python users with consistency with other

Since Waiman seems incapable of doing simple things; here's my take on the paravirt crap. The first few patches are taken from Waiman's latest series, but the virt support is completely new. Its primary aim is to not mess up the native code. I've not stress tested it, but the virt and paravirt (kvm) cases boot on simple smp guests. I've not done Xen, but the patch should be

This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than

This is really trying to cleanup some virt code, as suggested by Peter, who said > You could of course go fix that instead of mutilating things into > sort-of functional state. This work is needed for virtio, so it's probably easiest to merge it through my tree - is this fine by everyone? Arnd, if you agree, could you ack this please? Note to arch maintainers: please don't

v12->v13: - Change patch 9 to generate separate versions of the queue_spin_lock_slowpath functions for bare metal and PV guest. This reduces the performance impact of the PV code on bare metal systems. v11->v12: - Based on PeterZ's version of the qspinlock patch (https://lkml.org/lkml/2014/6/15/63). - Incorporated many of the review comments from Konrad Wilk and Paolo
