Move KERNBASE to 0xc0000000, giving the kernel a more-or-less full 1G
...
of virtual address space, leaving userland with 3G, and update comments
to match the new reality.
We knew we were going to have to bite this bullet eventually, and there
are a couple of outstanding PRs related to this issue (9389 and 9313).
Complete solution to those PRs is going to involve some sort of run-time
decision on how large kmem_map should be, as well as changing some data
structure allocation strategies in UVM. However, this change will at
least allow the PR submitter to simply throw resources at the problem.

d4713d24c2
Implement the kernel part of pr-1891. This allows for a more flexible sized
...
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

b8403d582b
don't be so quick to cast macro arguments to unsigned; if the
...
arguments are really off_t's (e.g. to btodb), then you can lose
information. This was the "> 4G file systems don't work" bug; physio
uses btodb, which was broken.

patch from rod grimes:
...
Fix definitions to be in terms of a minimum number of constants by
using the SHIFT value as the basis for the other values, for example
instead of:
#define NBPG 4096
#define PGSHIFT 12
use:
#define PGSHIFT 12
#define NBPG (1 << PGSHIFT)
