84009a0905 Check the major number of the boot device more carefully. There was only
a problem if the boot blocks passed bad data.

Check the major number of the dump device consistently.

f89f94ea93 Quote port names that have a digit in them. IO_TIMER1 was lexed as
{ port_name = "IO_TIMER", port_number = 1 } and only worked because
it was reassembled to "IO_TIMER1".  Trailing digits always work, but
this is too magic to depend on.

Don't quote port names that don't have a digit in them.

dd72da46f8 Add driver support for PCI fast ethernet adapters based on the
RealTek 8129/8139 chipset like I've been threatening. Update kernel
configs, userconfig.c, relnotes and sysinstall. No man page yet;
comming soon.

I consider this driver stable enough that I want to give it some
exposure in -current.

464de37ce6 *gulp*. Jordan specifically OK'ed this..
This is the bulk of the support for doing kld modules.  Two linker_sets
were replaced by SYSINIT()'s.  VFS's and exec handlers are self registered.
kld is now a superset of lkm.  I have converted most of them, they will
follow as a seperate commit as samples.
This all still works as a static a.out kernel using LKM's.

3defb6d13f Fixed two potentially serious classes of bugs:
1) The vnode pager wasn't properly tracking the file size due to
   "size" being page rounded in some cases and not in others.
   This sometimes resulted in corrupted files. First noticed by
   Terry Lambert.
   Fixed by changing the "size" pager_alloc parameter to be a 64bit
   byte value (as opposed to a 32bit page index) and changing the
   pagers and their callers to deal with this properly.
2) Fixed a bogus type cast in round_page() and trunc_page() that
   caused some 64bit offsets and sizes to be scrambled. Removing
   the cast required adding casts at a few dozen callers.
   There may be problems with other bogus casts in close-by
   macros. A quick check seemed to indicate that those were okay,
   however.

e23991ad03 Don't print conflict messages in haveseen_isadev() if CC_QUIET is
specified.  This makes haveseen_isadev() useful for searching for a
free resource.  This increases the bitrot in the pci RESOURCE_CHECK
code.

Fixed the pre-attach conflict message.  The flag for distinguishing
pre-attach conflict checks from pre-probe ones was never set.

482ceee22c Relocate the preload module info from machdep specifically rather than
trying to do it in locore.  We also walk through the module table
and relocate any MODINFO_ADDR pointers so that they become KVM relative
rather than physical addresses.  This means that hacks for adding
0xf0000000 in places like MFS go away.

04f5e2e068 Fix a parent tag reference count bug during tag teardown.
Enable optimization for nobounce_dmamap clients by setting the map
held by the client to NULL.  This allows the macros in bus.h to check
against a constant to avoid function calls.

Don't attempt to 'free()' contigmalloced pages in bus_dmamem_free().
We currently leak these pages, which is not ideal, but is better than
a panic.  The leak will be fixed when contigmalloc is merged into the
bus dma framework after 3.0R.

e708a51bd0 Initialize pcb_mpnest to 1 in the child process in cpu_fork(). This should
fix the 50% idle problem that the ELF /sbin/init triggered.  The problem
appeared when the last context switch before a fork() call was due to
the kernel faulting in user pages via normal page faults (e.g. copyin).

69bd3165a2 Ensure that the i8254 timecounter doesn't go backards. It sometimes
went backwards when interrupts were masked for more than one i8254
interrupt period.  It sometimes went backwards when the i8254 counter
was reprogrammed.  Neither of these should happen in normal operation.

Update the i8254 timecounter support variables atomically.  Calling
timecounter functions from fast interrupt handlers may actually work
in all cases now.

5a678e68e9 This implements retrieving the contents of message buffer via sysctl(3)
as "machdep.msgbuf". It's needed in case of using stripped kernels, where
normal dmesg (which has to use kvm) doesn't work.

The buffer is unwound, meaning that the data will be linear, possibly
with some leading NULLs.

5b11e2a2f4 Make profiling work for ELF. gprof now autodetects the format of
the executable file, so it will work for both a.out and ELF format
files.  I have split the object format specific code into separate
source files.  It's cleaner than it was before, but it's still
pretty crufty.

Don't cheat on your make world for this update.  A lot of things
have to be rebuilt for it to work, including the compiler and all
of the profiled libraries.
