At present reserving the IRLs in the IRQ bitmap in addition to the
dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being
allocated for the x3proto board.
The only reason to permit reservations was to lock down possible hardware
vectors prior to dynamic IRQ scanning, but this doesn't matter much given
that the hardware controller configuration is sorted before we get around
to doing any dynamic IRQ allocation anyways. Beyond that, all of the
tables are __init annotated, so quite a bit more work would need to be
done to support reconfiguring things like IRL controllers on the fly,
much more than would ever make it worth the hassle.

A bitmask property is similar to an enum. The enum value is a bit
position (0-63), and valid property values consist of a mask of
zero or more of (1 << enum_val[n]).

Poulsbo needs a physical address in the cursor base register. We allocate a
stolen memory buffer and copy the cursor image provided by userspace into it.
When/If we get our own userspace driver we can map this stolen memory directly.

I've been asked several times to provide more useful example configs for

If the file that OUTPUT_MIN_CONFIG exists then ktest.pl will prompt the
user and ask them if the OUTPUT_MIN_CONFIG should be used as the
starting point for make_min_config instead of MIN_CONFIG.
This is usually the case, and to allow the user to do so, which is
helpful if the user is creating different min configs based on tests,
and they know one is a superset of another test, they can set
USE_OUTPUT_MIN_CONFIG to one, which will prevent kest.pl from prompting
to use the OUTPUT_MIN_CONFIG and it will just use it.
If USE_OUTPUT_MIN_CONIFG is set to zero, then ktest.pl will continue to
use MIN_CONFIG instead.
The default is that USE_OUTPUT_MIN_CONFIG is undefined.

It's already called if TIF_NOTIFY_RESUME is set, so we only

TIF_NOTIFY_RESUME added (as bit 5). That way nommu glue needs no changes at
all; mmu one needs just to replace jmi do_signal_return to jne do_signal_return
There we have flags shifted up, until bit 6 (SIGPENDING) is in MSBit; instead
of checking that MSBit is set (jmi) we check that MSBit or something below it
is set (jne); bits 0..4 are never set, so that's precisely "bit 6 or bit 5 is
set".
Usual handling of NOTIFY_RESUME/SIGPENDING is done in do_notify_resume(); glue
calls it instead of do_signal().
