...vice from Matt Mackall about my personal appearance is best unrequited). The patch is split in 5 parts to correspond with the 9 parts Andrew sent out before, but here's the summary: 1) Sparse (thanks Christoph Hellwig): - lguest_const can be static now - lguest.c should include "lguest_bus.h" for lguest_devices declaration. - page_tables.c unnecessary initialization - But the cost was high: lots of __force casts 8( 2) Jeff Garzik - Use netdev_priv instead of dev->priv. - Check for ioremap failure - iounmap on failure. - Wrap SEND_DMA and BIND_DMA calls...

Hi Linus, First attempt at git, so please pull carefully. I've just put the three i386 boot changes in the repo for the moment. If this works I'll pile on the 44 lguest patches. git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux-2.6-lguest.git Documentation/i386/boot.txt | 34 +++++++++++++++++++++++++++- arch/x86/boot/compressed/head_32.S | 15 ++++++++++-

For virtio-scsi multiqueue support I would like to have an easy and fast way to go from a virtqueue to the internal struct for that queue. It turns out that virtio-serial has the same need, but it gets by with a simple list walk. This patch adds a pointer to struct virtqueue that is reserved for the virtio device, and uses it in virtio-serial. Cc: Amit Shah <amit.shah at redhat.com> Cc:
