  Revert changes to shared code of the ixl and ixlv drivers to allow
  for easier long-term maintainability.

  Restrict the drivers to building on amd64 for now as it is
  only tested on that 64bit architecture.

  Just depend on PCI and neither INET nor INET6; also make sure we
  can build individual drivers and they do not depend on each other
  anymore.

While I'm there, also implement a new build knob, WITHOUT_HYPERV to

The HyperV utilities are only built for i386 and amd64 targets.

This makes some space estimates more accurate and uses less memory

MFC r268376 (imp):

  rm -rf can fail sometimes with an error from fts_read. Make it
  honor fflag to ignore fts_read errors, but stop deleting from
  that directory because no further progress can be made.

  When building a kernel with a high -j value on a high core count
  machine, during the cleanobj phase we can wind up doing multiple
  rm -rf at the same time for modules that have subdirectories. This
  exposed this race (sometimes) as fts_read can return an error if
  the directory is removed by another rm -rf. Since the intent of
  the -f flag was to ignore errors, even if this was a bug in
  fts_read, we should ignore the error like we've been instructed
  to do.

MFC r272193

  Allow the PIC's IMR register to be read before ICW initialisation.

  As of git submit e179f6914152eca9, the Linux kernel does a simple
  probe of the PIC by writing a pattern to the IMR and then reading it
  back, prior to the init sequence of ICW words.

  The bhyve PIC emulation wasn't allowing the IMR to be read until
  the ICW sequence was complete. This limitation isn't required so
  relax the test.

  With this change, Linux kernels 3.15-rc2 and later won't hang
  on boot when calibrating the local APIC.

former allows the shell to catch variable names that are not valid
