Applied.

I is great that the compiler and interpreter share the same code.
However, there is also the risk of building dead compiler code
into the kernel.  We should probably do an analysis of that...

We've tried to be very careful about not including compiler-only code into kernel code.

I'm not entirely sure why patches 1,2, and 3 are applied against Linux. Perhaps Ming can answer this, or I'll take a look at the patches.

That is because the patches also changed the core code.

drivers/acpi/acpica/dsfield.c
include/acpi/actypes.h
drivers/acpi/acpica/utmisc.c

So we need to apply them to avoid divergence problem.
