That sounds like something is very fishy.

Thanks very much for this James! Applied after the Great Documentation
patch, so I'm adding some extra verbiage.
Cheers,
Rusty.

1) Use new lguest_send_dma & lguest_bind_dma functions.
2) sparse: lguest_cons can be static.

1) Use new dma wrapper functions, and handle bind failure (may happen
in future)
2) Use new lgdev_irq() "get me a good interrupt number" function.
3) __force the ioremap: guests can use it as normal memory.

Feedback from Jeff Garzik:
1) Use netdev_priv instead of dev->priv.
2) Check for ioremap failure
3) iounmap on failure.
4) Wrap SEND_DMA and BIND_DMA calls
5) Don't set NETIF_F_SG unless we set NETIF_F_NO_CSUM
6) Use SET_NETDEV_DEV()
7) Don't set dev->irq, mem_start & mem_end (deprecated)

1) Sam Ravnborg says lg-objs is deprecated, use lg-y.
2) Sparse: page_tables.c unnecessary initialization
3) Lots of __force to shut sparse up: guest "physical" addresses are
userspace virtual.

__iomem to cast, it ru
Hi all,
Gratefully-received recent feedback from CC'd was applied to excellent
effect (and the advice 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:
