linux/hdmi.h: Split out logic into .c file.

Shoulda done this ages ago.

only build linux_acpi.c if we have acpi(4) in the kernel

drm: Move acpi_check_dsm &c. from intel_acpi.c to new linux_acpi.c.

drm: Move io_mapping to very own .c file.

drm: linux kthread stubs

linux: Rename linux_sg.c -> linux_sgt.c.

Avoids collision with compat_linux.

linux: Kludgey radix tree shims

linux: Draft half-arsed xarray shims

linux: dma fence array stubs

linux: Draft irq_work shims, in terms of a softint.

Doesn't actually run in hardirq context, but who's gonna notice...

i915: more work

drm: Another pass over i915 and some supporting logic.

This makes a shim around sg_table, which essentially represents two
things:

1. an array of pages (roughly corresponding to bus_dma_segment_t[]

drm: Another pass over i915 and some supporting logic.

This makes a shim around sg_table, which essentially represents two
things:

1. an array of pages (roughly corresponding to bus_dma_segment_t[])
2. an array of DMA addresses stored in a bus_dmamap_t

Both parts are optional; different parts of i915 use sg_tables to
pass around one or both of the two parts. This helps to reduce the
ifdefs by quite a bit, although it's not always clear which part of
an sg_table any particular interface is actually using which is why I
was reluctant to do this before.

show more ...

linux compat: Draft hrtimer shims.

(not actually high-resolution, just a wrapper around callout(9))

linux: Draft rwsem with bodgy semantics.

Narrow the CPPFLAGS for drm subsystems.

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

Move Linux firmware shims to their own .c file.

dma fence chain stubs

backlight stubs

Draft sync_file.

Rename reservation_object -> dma_resv.

Move Linux SRCU to common.

Draft stop_machine. Hope the callback runs quickly under splhigh...

Move Linux RCU to common.

linux/wait_bit.h

Draft SRCU implementation.
