2b8d2018cc Set "lun = sess->d" early on (but not too early), and allow multiple 
targets to now work correctly.  XXX: This will need to be re-visited
at some point, and fixed properly.

0fa5922403 Add a '-D' option to allow "Discovery" of the targets provided by a host. 
Initial support for multiple targets from the same host.

Base 'MaxTargets' on a #define, rather than hard-coding.

83caeda725 - Fix the locking around the i8254. Values for the TSC clock and lapic 
delay function were wildly inaccurate due to multiple CPUs competing
  in DELAY() during calibration, confusing the clock chip.
- Use i8254_delay() explictly in a few more places.

05237843cf Newer nForce MCP SMBus devices use different PCI BARs than the old ones 
(nForce 2/3/4).

nfsmb(4) is now properly working on newer MCPs, tested by wiz@ on MCP55:

nfsmbc0 at pci0 dev 1 function 1: NVIDIA nForce MCP55 SMBus Controller (rev. 0xa2)
nfsmb0 at nfsmbc0 SMBus 1
iic0 at nfsmb0: I2C bus
spdmem0 at iic0 addr 0x51
spdmem0: DDR2 SDRAM memory, data ECC, 1024MB, 667MHz, PC2-5300
spdmem0: 14 rows, 10 cols, 2 ranks, 4 banks/chip, 3.00ns cycle time
spdmem0: voltage SSTL 1.8V, refresh time 7.8us (self-refreshing)

704f93353b Apply missed following MI wdc changes to atari's mainbus wdc backend: 
- make bus space handles an array for each command register
  http://mail-index.netbsd.org/source-changes/2003/11/27/0036.html
  (note we no longer have to specify stride for wdc after this change)
- add the notion of "shadow register"
  http://mail-index.netbsd.org/source-changes/2004/05/25/0048.html

Problem reported by Alan Hourihane in PR port-amiga/37464.

Fix the bus_dma(9) use in drm_pci.c and chnage struct drm_dma_handle_t
to match it.  Remove member dmaaddr from drm_dma_handle_t as well,
as I don't see it used anywhere.  Compile-tested only for now; please
report any problems to me.  Thanks.

a2a6dd1963 Define the various MIPS* CPU macros also for _STANDALONE in addition 
to for _LKM, so that we don't #error out in that case.

This fixes the build for sgimips boot programs, which wants to use
libkern, which now includes the atomic stuff, which for the mips ports
ends up including this file.

e5784d23f1 Add a CPU local timer based on the LAPIC. This is consistently faster 
than TSC, but doesn't suffer from SpeedStep as TSC does.

The default quality is higher than HPET for UP, but -100 for
MULTIPROCESSOR as it needs CPU local state which doesn't exist yet.

48e1704028 Use standard error code (EIO) instead of standalone error code 
(ESHORT).  Because loadfile_*() is used with or without
_STANDALONE, therefore, don't use error code in "saerrno.h".

33cb8be1db - add an elf aux vector entry for implementing $ORIGIN. 
- the code to convert from a vnode to a path is commented out now until
  a better solution is implemented. Only absolute paths work for now
  (which is most of the cases).
