fe6388dca2 As expected, things aren't as simple as hoped. Consequently, we have
no option but to use the smbios information to fill in the blanks.
It's a good thing UGA is a protocol of the past and GOP has all the
info we need.

Anyway, the logic has been tweaked a little to get the easier bits
of information up front. This includes the resolution and the frame
buffer address. Then we look at the smbios information and define
expected values as well as the missing bits (frame buffer offset and
stride). If the values obtained match the expect values, we fill in
the blanks and return. Otherwise we use the existing detection logic
to figure it out.

Rename the environment variables from uga_framebuffer abd uga_stride
to hw.efifb.address and hw.efifb.stride. The latter names are more
in line with other variable names.

We currently have hardcoded settings for:
1.  Mid-2007 iMac (iMac7,1)
2.  Late-2007 MacBook (MacBook3,1)

2a8ccb368f Eliminate pointless requeueing of pages from terminated objects. These
pages will have left the inactive queue before the page daemon performs
its next scan.  Also, ignore references to pages from terminated objects.
This allows the clean pages to be freed a little sooner.

Move some comments to their proper place, i.e., next to the code that
they describe, and update other nearby comments.

790dc6f94a Use Jenkins hash for TCP syncache.
o Unlike xor, in Jenkins hash every bit of input affects virtually
  every bit of output, thus salting the hash actually works. With
  xor salting only provides a false sense of security, since if
  hash(x) collides with hash(y), then of course, hash(x) ^ salt
  would also collide with hash(y) ^ salt. [1]
o Jenkins provides much better distribution than xor, very close to
  ideal.

TCP connection setup/teardown benchmark has shown a 10% increase
with default hash size, and with bigger hashes that still provide
possibility for collisions. With enormous hash size, when dataset is
by an order of magnitude smaller than hash size, the benchmark has
shown 4% decrease in performance decrease, which is expected and
acceptable.

Code using ifa_ifwith (and similar functins) along with

3b40d98a5d My MacBook has UGA only, but we fail to detect any changes
in the frame buffer when we flip pixels. Allow the detection
to be bypassed by setting the uga_framebuffer and uga_stride
variables. The kernel console works fine even when we can't
detect pixel changes in the frame buffer, which indicates
that the problem could be with reading from the frame buffer
and not writing to it.
