the addition of pci_find_extcap().
- Change the drm drivers to attach to vgapci. This is #ifdef'd so the
code can be shared across branches.
- Use pci_find_extcap() to look for AGP and PCIE capabilities in drm.
- GC all the drmsub stuff for i810/i830/i915. The agp and drm devices are
now both children of vgapci.
as a bus so that other drivers such as drm(4), acpi_video(4), and agp(4)
can attach to it thus allowing multiple drivers for the same device. It
also removes the need for the drmsub hack for the i8[13]0/i915 drm and agp
drivers.

attach to the hostb driver instead. This means that agp can now be loaded
at runtime (in theory at least). Also, the drivers no longer have to
explicity call device_verbose() to cancel out any earlier calls to
device_quiet() by the hostb(4) driver (this shows a limitation in new-bus,
drivers really shouldn't be doing device_quiet() until they know they are
going to drive that device, i.e. in attach).
duplicated anyways) and into a single MI driver. Extend the driver a bit
to implement the bus and PCI kobj interfaces such that other drivers can
attach to it and transparently act as if their parent device is the PCI
bus (for the most part).
ELF trampoline build its own target, "trampoline".
It makes it possible to construct a bootable gzipped kernel without having
to build in the same process.
drivers already map sections into KVA as needed anyway. Note that this
will probably break the nvidia driver, but I will coordinate to get that
fixed.

to search for a specific extended capability. If the specified capability
is found for the given device, then the function returns success and
optionally returns the offset of that capability. If the capability is
not found, the function returns an error.
The purpose of this change is consistency (not performance improvement:)),
as it was hard to tell if fdrop() is MPSAFE or not when I saw it sometimes
under the Giant and sometimes without it.

provide enough room for decompression (up to 2.5MB is necessary). This
should be safe to do since we load i386 kernels after 8MB mark now, so
that 16MB is the minimum amount of RAM necessary to even boot FreeBSD.
This makes bzip2-support practically useable.
memory directly available to loader(8) and friends was limited to 640K on i386.
Those times have passed long time ago and now loader(8) can directly access
up to 4GB of RAM at least theoretically. At the same time, there are several
places where it's assumed that malloc() will only allocate memory within
first megabyte.
Remove that assumption by allocating appropriate bounce buffers for BIOS
calls on stack where necessary.
This allows using memory above first megabyte for heap if necessary.
1. The ELF-64 typedefs are now standardized, so that the libelf port
(devel/libelf) does not need to compensate for not having the
Elf64_Xword and Elf64_Sxword types.
2. ELF Symbol versioning support has been added. This also affects
the libelf port (though configure should detect this correctly).
we can cache its value in the softc. Eliminates one PCI register
write per call to bge_start().

incorrectly in almost all drivers. Indicate failure with

means:
o Remove Elf64_Quarter,
o Redefine Elf64_Half to be 16-bit,
o Redefine Elf64_Word to be 32-bit,
o Add Elf64_Xword and Elf64_Sxword for 64-bit entities,
o Use Elf_Size in MI code to abstract the difference between
Elf32_Word and Elf64_Word.
o Add Elf_Ssize as the signed counterpart of Elf_Size.

o Remove the unused and non-standard SHT_NUM, PT_COUNT and DT_COUNT.
o Add the STV_DEFAULT, STV_INTERNAL, STV_HIDDEN and STV_PROTECTED
symbol visibility constants.
o Add the ELF32_ST_VISIBILITY and ELF64_ST_VISIBILITY macros to
get the symbol visibility from the st_other field.
o Add the ELFOSABI_AIX, ELFOSABI_OPENVMS and ELFOSABI_NSK constants.
o Add the ET_LOOS, ET_HIOS, ET_LOPROC and ET_HIPROC constants.
o Further flesh out the list of machine types. Note that EM_ALPHA
remains non-standard. The standard value for EM_ALPHA is given
by EM_ALPHA_STD (which is a non-standard name :-)
o Add the SHN_LOOS, SHN_HIOS and SHN_XINDEX constants.
o Add the SHT_INIT_ARRAY, SHT_FINI_ARRAY, SHT_PREINIT_ARRAY, SHT_GROUP
and SHT_SYMTAB_SHNDX constants.
o Add the SHF_MERGE, SHF_STRINGS, SHF_INFO_LINK, SHF_LINK_ORDER,
SHF_OS_NONCONFORMING, SHF_GROUP and SHF_MASKOS constants.
o Add the PF_MASKOS and PF_MASKPROC constants.
o Add the STB_LOOS andf STB_HIOS constants.
o Add the STT_COMMON, STT_LOOS and STT_HIOS constants.
