vdev->guest_features is not masking features that are not supported by
the guest. Fix this by introducing a common wrapper to be used by all
virtio bus implementations.

Small requirements on "new" features have percolated to virtio-9p-local.c.
In particular, the utimensat wrapper actually only supports dirfd = AT_FDCWD
and flags = AT_SYMLINK_NOFOLLOW in the fallback code. Remove the arguments
so that virtio-9p-local.c will not use AT_* constants.
At the same time, fail local_ioc_getversion if the ioctl is not supported
by the host.

This reverts commit 66e3dd9282.
From Avi,
"Anthony, I think we should revert that commit and refactor cpuid for
1.1. The logic is spread over too many places which makes it hard to
reason about."

Also add omap_l4_region_size(), since memory API functions need
the size during initialization.

This is a trivial wrapper around cpu_register_io_memory(), adding
no value. Inline it into all callers.

This was introduced apparently to overcome a limitation on the number of
cpu_register_io_memory() calls. 477b24ef91 (July 2008) removed use
of the hack, but retained the code. This patch removes the code as well.

We should only claim that something is a cast if we did not encouter a
token before, that did set av_pending.
This fixes the operator * in the line below to be detected as binary (vs
unary).
kmalloc(sizeof(struct alphatrack_ocmd) * true_size, GFP_KERNEL);
