ddebd8c08e After careful review of this driver, I'm pretty sure it would take a
lot of work to make this driver work under current.  In the past when
people wanted to remove xten, I was the only one in the way.  After
talking to fsmp@ (last person to make real changes to this driver)
about this, I'm convinced it is better left in the dust-bin of history

ec7071fcb8 - Push down Giant into the sysarch() calls that still need Giant.

3d51b3a280 Add an argument to get_mcontext() which specified whether the
syscall return values should be cleared.  The system calls
getcontext() and swapcontext() want to return 0 on success
but these contexts can be switched to at a later time so
the return values need to be cleared in the saved register
sets.  Other callers of get_mcontext() would normally want
the context without clearing the return values.

Remove the i386-specific context saving from the KSE code.
get_mcontext() is not i386-specific any more.

Fix a bad pointer in the alpha get_mcontext() code.  The
context was being bcopy()'d from &td->tf_frame, but tf_frame
is itself a pointer, so the thread was being copied instead.

6afbdfe8ea Update the DRM to the latest from DRI CVS. Includes some bugfixes and removal
of the infrastructure for the gamma driver which was removed a while back.
The DRM_LINUX option is removed because the handler is now provided by the
linux compat code itself.

d0165cba28 Fix some problems for cpu_switch_load_gs. when fault address is at
cpu_switch_load_gs, cpu is in context switch, so don't enable interrupt.
because it is in context switch, it is expected sched_lock was held,
so don't PROC_LOCK(p) and psignal, it is LOR, probably we can
set a P_XSIGBUS like flag in p_sflags, and set TDF_ASTPENDING in
td_flags, in ast(), post a SIGBUS to process if P_XSIGBUS was set.

e41f6225fa Add device driver support for the ASIX Electronics AX88172 USB 2.0
ethernet controller. The driver has been tested with the LinkSys
USB200M adapter. I know for a fact that there are other devices out
there with this chip but don't have all the USB vendor/device IDs.

Note: I'm not sure if this will force the driver to end up in the
install kernel image or not. Special magic needs to be done to exclude
it to keep the boot floppies from bloating again, someone please
advise.

a350d6ddb9 * Use _bus_dmamap_load_buffer() and respect maxsegsz in bus_dmamap_load().
Ignoring maxsegsz may lead to fatal data corruption for some devices.
ex. SBP-2/FireWire
We should apply this change to other platforms except for sparc64.

eff9d3d98d Add support for bounce buffers to _bus_dmamap_load_buffer, which is the
backend for bus_dmamap_load_mbuf and bus_dmamap_load_uio.

- Increaes MAX_BPAGES to 512.  Less than this causes fxp to quickly runs out
  of bounce pages.
- Add an argument to reserve_bounce_pages indicating wether this operation
  should fail or be queued for later processing if we run out of memory.
  The EINPROGRESS return value is not handled properly by consumers of
  bus_dmamap_load_mbuf.
- If bounce buffers are required allocate minimum 1 bounce page at map
  creation time.  If maxsize was small previously this could get truncated
  to 0 and the drivers would quickly run out of bounce pages.
- Fix a bug handling the return value of alloc_bounce_pages at map creation
  time.  It returns the number of pages allocated, not 0 on success.
- Use bus_addr_t for physical addresses to avoid truncation.
- Assert that the map is non-null and not the no bounce map in
  add_bounce_pages.

204303829b Better fix for previous previous which still allows the 4megs of kva at
the top of the address space to be reclaimed.  The problem is that with
the APTD gone the mapable kernel address space runs right to the end of
the 32 bit address space.  As a max this is 0x100000000, which can't be
represented in 32 bits, so we have to use ptd entry n-1 and pte offset
n-1, instead of ptd entry n and pte offset 0.  There's still 1 page we
can't use, but we gain just under 4 megs of kva (8 megs with PAE).

5468286a89 Define ovbcopy() as a macro which expands to the equivalent bcopy() call,
to take care of the KAME IPv6 code which needs ovbcopy() because NetBSD's
bcopy() doesn't handle overlap like ours.

Remove all implementations of ovbcopy().

Previously, bzero was a function pointer on i386, to save a jmp to
bzero_vector.  Get rid of this microoptimization as it only confuses
things, adds machine-dependent code to an MD header, and doesn't really
save all that much.

This commit does not add my pagezero() / pagecopy() code.
