src/sys/modules/hyperv, branch release/12.4.0

Move most of the contents of opt_compat.h to opt_global.h.

2018-04-06T17:35:35+00:00

opt_compat.h is mentioned in nearly 180 files. In-progress network
driver compabibility improvements may add over 100 more so this is
closer to "just about everywhere" than "only some files" per the
guidance in sys/conf/options.

Keep COMPAT_LINUX32 in opt_compat.h as it is confined to a subset of
sys/compat/linux/*.c.  A fake _COMPAT_LINUX option ensure opt_compat.h
is created on all architectures.

Move COMPAT_LINUXKPI to opt_dontuse.h as it is only used to control the
set of compiled files.

Rename assym.s to assym.inc

2018-03-20T17:58:51+00:00

assym is only to be included by other .s files, and should never
actually be assembled by itself.

hyperv/vmbus: Reorganize vmbus device tree

2017-05-10T05:28:14+00:00

For GEN1 Hyper-V, vmbus is attached to pcib0, which contains the
resources for PCI passthrough and SR-IOV.  There is no
acpi_syscontainer0 on GEN1 Hyper-V.

For GEN2 Hyper-V, vmbus is attached to acpi_syscontainer0, which
contains the resources for PCI passthrough and SR-IOV.  There is
no pcib0 on GEN2 Hyper-V.

The ACPI VMBUS device now only holds its _CRS, which is empty as
of this commit; its existence is mainly for upward compatibility.

Device tree structure is suggested by jhb@.

This makes the file name and the variable naming in the file consistent.
