c9f6794e2e One more round on the H/W supported checksum code: Fix NICs that can't do
the pseudo header. We really need the TCP packet length here. This happens
to end up in ip->ip_len in tcp_input.c, but here we should get it from the
len function variable instead.

1e7fad6b6a Revert the previous round of changes to td_pinned. The scheduler isn't
fully initialed when the pmap layer tries to call sched_pini() early in the
boot and results in an quick panic.  Use ke_pinned instead as was originally
done with Tor's patch.

9e0c3bdf64 Double the number of kernel page tables for amd64 and for i386/PAE. The old
value was only enough for 8GB of RAM, the new value can do 16GB.  This still
isn't optimal since it doesn't scale.  Fixing this for amd64 looks to be
fairly easy, but for i386 will be quite difficult.

a07bd003bf Add device driver support for the VIA Networking Technologies
VT6122 gigabit ethernet chip and integrated 10/100/1000 copper PHY.
The vge driver has been added to GENERIC for i386, pc98 and amd64,
but not to sparc or ia64 since I don't have the ability to test
it there. The vge(4) driver supports VLANs, checksum offload and
jumbo frames.

Also added the lge(4) and nge(4) drivers to GENERIC for i386 and
pc98 since I was in the neighborhood. There's no reason to leave them
out anymore.

7f4caa8c59 Add mkuzip(8), non-GPL utility to compress filesystem images for use with
geom_uzip module. This is based on utility I wrote some 3 years ago for a
hack for md(4), which functionally was close to what geom_uzip does today.

Since I don't have a time to test that it compiles/works on other arches,
stick it to i386 only. Will do it later.

Unlike original cloop util, this one embedds FreeBSD-compatible shell code
into the generated image, not Linux one. Unfortunately severe space
restriction imposed by the CLOOP format doesn't allow to put conditional
code which will work both on Linux and FreeBSD. In fact it was quite a
challenge to fit necessary FreeBSD code into 127 bytes. ;-)

a5906b6cd2 I found "portsdb -u" dumps core with recent INDEX file, and this is
caused by refering broken (uninitialized?) pointer which is retrieved
from __bt_new() (and from mpool_new()).

I don't know why this linp[0] is read before stored because this
should be controlled by .lower and .upper member of PAGE structure
which are correctly initialized.

But this workaround fixes the problem on my environment and this
module has #ifdef PURIFY option which initializes new and reused
memory from mpool by memset(p, 0xff, size) like as I did.

Please feel free to fix the real bug instead of my workaround.

ca219d048a Convert sndstat_lock from a mutex to an sx lock. sndstat_read()
holds sndstat_lock across a call to uiomove(), which is not legal
to do with a  mutex because of the possibility that the data transfer
could sleep because of a page fault.  It is not possible to just
unlock the mutex for the uiomove() call without introducing another
locking mechanism to prevent the body of sndstat_read() from being
re-entered.  Converting sndstat_lock to an sx lock is the least
complicated change.

This is a candidate for RELENG_5.

e4793b0eda Better fix the busdma problem exposed by ATA. With the CMD 646 for
example the maximum segment size is 64K while the boundary is set
to 8K due to controller limitations. It is impossible to NOT cross
the boundary for any segment size that's larger than the boundary.
So, once we inherited the boundary from the parent tag, make sure
to reduce the maximum segment size to the boundary if it was larger.

7dafab2e78 The previous commit, roughly one and a half years ago removed the
branch prediction optimization for LINT, because the kernel was too
large. This commit now removes it altogether since it causes build
failures for GENERIC kernels and the various applicable trends are
such that one can expect that it these failure will cause more
problems than they're worth in the future. These trends include:
1. Alpha was demoted from tier 1 to tier 2 due to lack of active
   support. The number of people willing to fix build breakages
   is not likely to increase and those developers that do have the
   gumption to test MI changes on alpha are not likely to spend
   time fixing unexpected build failures first.
2. The kernel will only increase in size. Even though stripped-down
   kernels do link without problems now, compiler optimizations (like
   inlining) and new (non-optional) functionality will likely cause
   stripped-down kernels to break in the future as well.

So, with my asbestos suit on, get rid of potential problems before
they happen.
