apply ${CC_WNO_ENUM_INT_MISMATCH} for nouveau_dispnv50_wndw.c

XXX: this may be a real bug.

drm: Set CONFIG_ACPI in linux/acpi.h and make it build.

Leave a little ACPI-related functionality disabled for now, like
getting EDID out of ACPI -- needs a bit more work to make this work,
and I don't have hardware to work on that.

Should help with failures of the forms:

- unable to locate a BIOS ROM
- bios: unable to locate usable image

on various machines.

adapt to ${CC_WNO_IMPLICIT_FALLTHROUGH}

Use ${CC_WNO_IMPLICIT_FALLTHROUGH} instead of
the older style more complex expressions.

drm: Propagate CPPFLAGS.drmkms into all the drm drivers.

drm: sprinkle some -Wno-unused-function for clang

915_sw_fence.c: for debug_fence_init_onstack
drm_mm.c: for rb_hole_size_to_node
intel_hdmi.c: for intel_hdmi_hdcp2_protocol
intel_guc_submission.c: for rq_prio
nouveau_nvkm_subdev_instmem_base.c: for fake_ioread32_native
nouveau_nvkm_subdev_mmu_vmmnv04.c: for nv04_vmm_pgt_pte

Revert part of previous: no separate CPPFLAGS.drmkms.

There are too many drms users outside sys/external/bsd/drm2 for now;
will hold off on this until we find a better way to keep the drm
includes modularized.

Narrow the CPPFLAGS for drm subsystems.

No need for the whole kernel to be built with -I flags for the drm
header files.

Get nouveau compiling.

Compile all of nouveau with -Wno-pointer-arith.

Delete nouveau_sysfs.c, removed upstream.

Generate files.* using the 2netbsd scripts.

drm2: build with -fwrapv, since the Linux kernel does and we don't
want to spend too much time fixing their code. silences a lot of
KUBSAN warnings.

we need to use COPTS to have per-option compiler flags. help from
Riastradh.

branches: 1.29.10; 1.29.14;
Eliminate -Wpointer-arith patches; use -Wno-pointer-arith instead.

branches: 1.28.2;
convert HAVE_GCC == 7 to HAVE_GCC >= 7.

nouveau uses firmload, add dependency.

add -Wno-error=int-in-bool-context or -Wno-error=implicit-fallthrough
for various drm files that would be best ignored or upstream fixed.
(could fix savagedrm, no one upstream is that any more.)

Fix merge botch

Merge the [pgoyette-compat] branch

Limit warning suppression to nouveau files.

Make this match what I have in my drmkms update.

Please don't touch files under sys/external/bsd/drm2 without
consulting me while I'm updating drmkms!

nouveau_nv50_display.c and nouveau_nvif_client.c have variable structures
not at the end of a structure.

Tag files.* with newer config version where needed.

Tag with nouveau, not just nouveau_pci, to get CWARNFLAGS.nouveau.

Make drmkms build without drmkms_pci.

Draft support for drm prime.

Teach nouveau to read its own header files.

regen files.nouveau

Replace nouveau per-file warning options by nouveau-wide options.

branches: 1.14.16; 1.14.18;
Set nouveau to a more reasonable debug level.

Match the compile-time and default run-time settings in Linux.

Restrict -Wno-unused-but-set-variable to gcc.

sprinkle -Wno-missing-field-initializers

Backport GK20A support from linux-3.16.

ok riastradh@

nouveau_pci.c depends on nouveau_pci condition, not nouveau

Split nouveau@pci from nouveau so we can attach it to other busses.
nouveaufb still depends on nouveau_pci, but it is not applicable to
non-PCI devices anyway.

One last round for nouveau. It links!

Another round of nouveau whack-a-mole.

Nouveau compiles now, though it doesn't link yet.

Need to write driver attachment, wscons framebuffer, &c. Probably
also some i2c stuff.

Another round of whack-a-mole with nouveau.

Another round of nouveau whack-a-mole.

nouveau_nv50_fence.c needs -Wno-shadow.
