ce7fd13aff Convert BERI to use ofw_parse_bootargs()
Summary:
ofw_parse_bootargs() was added in r306065 as an attempt to unify the
various copies of the same code.  This simply migrates BERI to use it.

8d6fbbb867 Replace manyinstances of VM_WAIT with blocking page allocation flags
similar to the kernel memory allocator.

This simplifies NUMA allocation because the domain will be known at wait
time and races between failure and sleeping are eliminated.  This also
reduces boilerplate code and simplifies callers.

A wait primitive is supplied for uma zones for similar reasons.  This
eliminates some non-specific VM_WAIT calls in favor of more explicit
sleeps that may be satisfied without new pages.

8e94025b41 With r181803 on 2008-08-17 23:27:27Z the first VIMAGE commit went into
HEAD.  Enable VIMAGE in GENERIC kernels and some others (where GENERIC does
not exist) on HEAD.

Disable building LINT-VIMAGE with VIMAGE being default.

This should give it a lot more exposure in the run-up to 12 to help
us evaluate whether to keep it on by default or not.
We are also hoping to get better performance testing.
The feature can be disabled using nooptions.

46fcd1af63 Move kernel dump offset tracking into MI code.
All of the kernel dump implementations keep track of the current offset
("dumplo") within the dump device. However, except for textdumps, they
all write the dump sequentially, so we can reduce code duplication by
having the MI code keep track of the current offset. The new
dump_append() API can be used to write at the current offset.

This is needed to implement support for kernel dump compression in the
MI kernel dump code.

Also simplify dump_encrypted_write() somewhat: use dump_write() instead
of duplicating its bounds checks, and get rid of the redundant offset
tracking.

89294a783a bhnd: Add support for supplying bus I/O callbacks when initializing an EROM
parser.

This allows us to use the EROM parser API in cases where the standard bus
space I/O APIs are unsuitable. In particular, this will allow us to parse
the device enumeration table directly from bhndb(4) drivers, prior to
full attach and configuration of the bridge.

8e35bf8319 bhnd: Implement bhnd(4) platform device registration.
Add bhnd(4) API for explicitly registering BHND platform devices (ChipCommon,
PMU, NVRAM, etc) with the bus, rather than walking the newbus hierarchy to
discover platform devices. These devices are now also refcounted; attempting
to deregister an actively used platform device will return EBUSY.

This resolves a lock ordering incompatibility with bwn(4)'s firmware loading
threads; previously it was necessary to acquire Giant to protect newbus access
when locating and querying the NVRAM device.

c2f37b9245 Add AT_HWCAP and AT_EHDRFLAGS on all platforms.
A new 'u_long *sv_hwcap' field is added to 'struct sysentvec'.  A
process ABI can set this field to point to a value holding a mask of
architecture-specific CPU feature flags.  If an ABI does not wish to
supply AT_HWCAP to processes the field can be left as NULL.

The support code for AT_EHDRFLAGS was already present on all systems,
just the #define was not present.  This is a step towards unifying the
AT_* constants across platforms.

In particular, MIPS now has COMPAT_FREEBSD32 for n64 kernels so this

7692d200c1 Use better hard-coded defaults for the cursor shape, and remove nearby
redundant initializations.

Hard-code base = 0, height = (approx. 1/8 of the boot-time font height)
in all cases, and remove the BIOS/MD support for setting these values.
This asks for an underline cursor sized for the boot-time font instead
of various less hard-coded but worse values.  I used that think that
the x86 BIOS always gave the same values as the above hard-coding, but
on 1 of my systems it gives the wrong value of base = 1.

The remaining BIOS fields are shift_state and bell_pitch.  These are now
consistently not explicitly reinitialized to 0.  All sc_get_bios_value()
functions except x86's are now empty, and the only useful thing that x86
returns is shift_state.  This really belongs in atkbdc, but heavier
use of the BIOS to read the more useful typematic rate has been removed
there.  fb still makes much heavier use of the BIOS.

eb36b1d0bc Clean up MD pollution of bus_dma.h:
--Remove special-case handling of sparc64 bus_dmamap* functions.
  Replace with a more generic mechanism that allows MD busdma
  implementations to generate inline mapping functions by
  defining WANT_INLINE_DMAMAP in <machine/bus_dma.h>.  This
  is currently useful for sparc64, x86, and arm64, which all
  implement non-load dmamap operations as simple wrappers
  around map objects which may be bus- or device-specific.

--Remove NULL-checked bus_dmamap macros.  Implement the
  equivalent NULL checks in the inlined x86 implementation.
  For non-x86 platforms, these checks are a minor pessimization
  as those platforms do not currently allow NULL maps.  NULL
  maps were originally allowed on arm64, which appears to have
  been the motivation behind adding arm[64]-specific barriers
  to bus_dma.h, but that support was removed in r299463.

--Simplify the internal interface used by the bus_dmamap_load*
  variants and move it to bus_dma_internal.h

--Fix some drivers that directly include sys/bus_dma.h
  despite the recommendations of bus_dma(9)

2d88da2f06 Move struct syscall_args syscall arguments parameters container into
struct thread.

For all architectures, the syscall trap handlers have to allocate the
structure on the stack.  The structure takes 88 bytes on 64bit arches
which is not negligible.  Also, it cannot be easily found by other
code, which e.g. caused duplication of some members of the structure
to struct thread already.  The change removes td_dbg_sc_code and
td_dbg_sc_nargs which were directly copied from syscall_args.

The structure is put into the copied on fork part of the struct thread
to make the syscall arguments information correct in the child after
fork.

This move will also allow several more uses shortly.
