This new config enables KVM (and thus LPAE) on top of
multi_v7_defconfig. This creates a kernel that can _host_ KVM guests,
for guests a multi_v7_defconfig with virtio drivers is sufficient.
Since LPAE kernels are not compatible with non-LPAE capable hardware,
this has to be separate from the exist
To make multi_v7_defconfig really "multi", let's add virtio drivers
to allow booting a default kernel as a KVM/QEMU guest.
MACH_VIRT is already defined, so we just add VIRTIO_BLK, VIRTIO_NET
and VIRTIO_CONSOLE to actually make this kernel useful in a guest.

Hi,
there doesn't seem to be a good generic defconfig which includes
KVM support, so this config tends to get less testing.
This mini-series addresses this with a two-fold approach:

so those kernels can be easily used as gues

Change the select and deselect op to work in terms of the mux core instead
of the child adapter. No driver uses the child adapter anyway, and if it

The dev pointer is readily available in the mux core struct, no point in
keeping multiple copies around.

Add i2c_lock_bus() and i2c_unlock_bus(), which call the new lock_bus and
unlock_bus ops in the adapter. These funcs/ops take an additional flags
argument that indicates for what purpose the adapter is locked.
There are two flags, I2C_LOCK_ADAPTER and I2C_LOCK_SEGMENT, but they
From: Peter Rosin
Instead of checking for i2c parent adapters for every lock/unlock, simply
override the locking for muxes to always lock/unlock the parent adapter
directly.

The initial core mux structure starts off small with only the parent

driver private data.
Add i2c_mux_alloc function to unify the creation of a mux.

The current driver uses input clock source frequency to calculate
values for [SS|FS]_[HC|LC] registers. However, when booting ACPI, we do not
currently have a good way to provide the frequency information.
Instead, we can leverage the SSCN and FFCN ACPI methods, which can be used
to directly provid

It would be quite good if the commit messaged said why it is now safe to
