2b78d30630 Remove the uscanner(4) driver, this follows the removal of the kernel scanner
driver in Linux 2.6. uscanner was just a simple wrapper around a fifo and
contained no logic, the default interface is now libusb (supported by sane).

a4f2b2b0c6 Add AT_EXECPATH ELF auxinfo entry type. The value's a_ptr is a pointer
to the full path of the image that is being executed.
Increase AT_COUNT.

Remove no longer true comment about types used in Linux ELF binaries,
listed types contain FreeBSD-specific entries.

c66d2b38c8 Initial suspend/resume support for amd64.
This code is heavily inspired by Takanori Watanabe's experimental SMP patch
for i386 and large portion was shamelessly cut and pasted from Peter Wemm's
AP boot code.

e5adda3d51 Remove IFF_NEEDSGIANT, a compatibility infrastructure introduced
in FreeBSD 5.x to allow network device drivers to run with Giant
despite the network stack being Giant-free.  This significantly
simplifies calls into ioctl() on network interfaces, especially
in the multicast code, as well as eliminates deferred invocation
of interface if_start routines.

Disable the build on device drivers still depending on
IFF_NEEDSGIANT as they no longer compile.  They will be removed
in a few weeks if they haven't been made MPSAFE in that time.
Disabled drivers:

        if_ar
        if_axe
        if_aue
        if_cdce
        if_cue
        if_kue
        if_ray
        if_rue
        if_rum
        if_sr
        if_udav
        if_ural
        if_zyd

Drivers that were already disabled because of tty changes:

        if_ppp
        if_sl

32c01de21c Implement new way of branding ELF binaries by looking to a
".note.ABI-tag" section.

The search order of a brand is changed, now first of all the
".note.ABI-tag" is looked through.

Move code which fetch osreldate for ELF binary to check_note() handler.

2ee8325f42 A better fix for handling different FPU initial control words for different
ABIs:
- Store the FPU initial control word in the pcb for each thread.
- When first using the FPU, load the initial control word after restoring
  the clean state if it is not the standard control word.
- Provide a correct control word for Linux/i386 binaries under
  FreeBSD/amd64.
- Adjust the control word returned for fpugetregs()/npxgetregs() when a
  thread hasn't used the FPU yet to reflect the real initial control
  word for the current ABI.
- The Linux/i386 ABI for FreeBSD/i386 now properly sets the right control
  word instead of trashing whatever the current state of the FPU is.

20e9dede5e Some cleanups to the i386 FPU support:
- Remove the control word parameter to npxinit().  It was always set
  to __INITIAL_NPXCW__.
- Remove npx_cleanstate_ready as the cleanstate is always initalized
  when it is used.
- Improve the handling of the case when the FPU isn't present.  Now
  the npx0 device no longer succeeds in its probe so all of npx_attach()
  is skipped.  Also, we allow this case with SMP (though that shouldn't
  actually occur as all i386 systems that support SMP have FPUs) now.
  SMP was only an issue back when we had an FPU emulator which was not
  per-CPU.
- MFamd64: Clear some of the state in npx_cleanstate rather than leaving
  it as garbage.
- MFamd64: When a user thread first uses the FPU, use npx_cleanstate for
  the initial FPU state.

b25fc07f53 At least one BIOS bogusly includes duplicate entries for I/O APICs. The
bogus entries have a starting IRQ that is invalid (> 255, so won't fit
into a PCI intline config register).  It had the side effect of breaking
MSI by "claiming" several IRQs in the MSI range.  Fix this by ignoring such
I/O APICs.

96c7367b9e The bounce zone sees its page number increased if multiple dma maps use it in
the same dma tag. However, it can happen multiple dma tags share the same
bounce zone too, so add a per-bounce zone map counter, and check it instead of
the dma tag map counter, to know if we have to alloc more pages.

047e5fdabc When bouncing pages, allow a new option to preserve the intra-page
offset.  This is needed for the ehci hardware buffer rings that assume
this behavior.

This is an interim solution, and a more general one is being worked
on.  This solution doesn't break anything that doesn't ask for it
directly.  The mbuf and uio variants with this flag likely don't work
and haven't been tested.

Universe builds with these changes.  I don't have a huge-memory
machine to test these changes with, but will be happy to work with
folks that do and hps if this changes turns out not to be sufficient.
