When address space isolation is active, cpu_tlbstate isn't necessarily
mapped in the ASI page-table, this would cause ASI to fault. Instead of
just mapping cpu_tlbstate, update __get_current_cr3_fast() and
cr4_read_shadow() by caching the cr3/cr4 values in the ASI session

Hi,
This is version 2 of the "KVM Address Space Isolation" RFC. The code
has been completely changed compared to v1 and it now provides a generic

Steve, I've not yet seen a quick fix that actually fixes all the
problems.
Your initial one only fixes the IRQ tracing one, but leaves the context
tracking
-EINVAL is not a valid return value for .of_map_mode, return
REGULATOR_MODE_INVALID instead.

The older CSI drivers have camera capture interface different from the one
in the newer ones.
This IP is pretty simple. Some variants (one controller out of two
instances on some SoCs) have an ISP embedded, but there's no code that make
use of it, so we ignored that part for now.

The Allwinner A10 CMOS Sensor Interface is a camera capture interface also
used in later (A10s, A13, A20, R8 and GR8) SoCs.
On some SoCs, like the A10, there's multiple instances of that controller,
with one instance supporting more channels and having an ISP.

The Makefile and Kconfig for the sun6i CSI driver are included in the main
Makefile / KConfig file. Since we're going to add a new CSI driver for an
older chip, and the Cedrus driver eventually, it makes more sense to put
those in our directory.

The CSI controller embedded in the A20 can be supported by our new driver.
Let's add it to our DT.

Hi,
Here is a series introducing the support for the A10 (and SoCs of the same
generation) CMOS Sensor Interface (called CSI, not to be confused with
MIPI-CSI, which isn't support by that IP).
That interface is pretty straightforward, but the driver has a few issues
that I wanted to bring up:
