They were empty nops. - Retire sl_xname and use device_get_nameunit() and device_printf() with the underlying device_t instead. - Remove unused {ct,ncv,nsp,stg}print() functions. - Remove empty SOFT_INTR_REQUIRED() macro and the unused sl_irq member.

Remove NetBSD compat shims for drivers originally shared with NetBSD/pc98. NetBSD/pc98 was never merged into the main NetBSD tree and is no longer developed. Adding locking to these drivers would have made the compat shims hard to impossible to maintain, so remove the shims to ease future changes.
These changes were verified by md5. Some additional shims can be removed that do affect the compiled results that I will probably do in another round.

Add descriptor sense support to CAM, and honor sense residuals properly in CAM.
Desriptor sense is a new sense data format that originated in SPC-3. Among other things, it allows for an 8-byte info field, which is necessary to pass back block numbers larger than 4 bytes.
This change adds a number of new functions to scsi_all.c (and therefore libcam) that abstract out most access to sense data.
This includes a bump of CAM_VERSION, because the CCB ABI has changed. Userland programs that use the CAM pass(4) driver will need to be recompiled.
camcontrol.c: Change uses of scsi_extract_sense() to use scsi_extract_sense_len().
Use scsi_get_sks() instead of accessing sense key specific data directly.
scsi_modes: Update the control mode page to the latest version (SPC-4).
scsi_cmds.c, scsi_target.c: Change references to struct scsi_sense_data to struct scsi_sense_data_fixed. This should be changed to allow the user to specify fixed or descriptor sense, and then use scsi_set_sense_data() to build the sense data.
ps3cdrom.c: Use scsi_set_sense_data() instead of setting sense data manually.
cam_periph.c: Use scsi_extract_sense_len() instead of using scsi_extract_sense() or accessing sense data directly.
cam_ccb.h: Bump the CAM_VERSION from 0x15 to 0x16. The change of struct scsi_sense_data from 32 to 252 bytes changes the size of struct ccb_scsiio, but not the size of union ccb. So the version must be bumped to prevent structure mis-matches.
scsi_all.h: Lots of updated SCSI sense data and other structures.
Add function prototypes for the new sense data functions.
Take out the inline implementation of scsi_extract_sense(). It is now too large to put in a header file.
Add macros to calculate whether fields are present and filled in fixed and descriptor sense data
scsi_all.c: In scsi_op_desc(), allow the user to pass in NULL inquiry data, and we'll assume a direct access device in that case.
Changed the SCSI RESERVED sense key name and description to COMPLETED, as it is now defined in the spec.
Change the error recovery action for a number of read errors to prevent lots of retries when the drive has said that the block isn't accessible. This speeds up reconstruction of the block by any RAID software running on top of the drive (e.g. ZFS).
In scsi_sense_desc(), allow for invalid sense key numbers. This allows calling this routine without checking the input values first.
Change scsi_error_action() to use scsi_extract_sense_len(), and handle things when invalid asc/ascq values are encountered.
Add a new routine, scsi_desc_iterate(), that will call the supplied function for every descriptor in descriptor format sense data.
Add scsi_set_sense_data(), and scsi_set_sense_data_va(), which build descriptor and fixed format sense data. They currently default to fixed format sense data.
Add a number of scsi_get_*() functions, which get different types of sense data fields from either fixed or descriptor format sense data, if the data is present.
Add a number of scsi_*_sbuf() functions, which print formatted versions of various sense data fields. These functions work for either fixed or descriptor sense.
Add a number of scsi_sense_*_sbuf() functions, which have a standard calling interface and print the indicated field. These functions take descriptors only.
Add scsi_sense_desc_sbuf(), which will print a formatted version of the given sense descriptor.
Pull out a majority of the scsi_sense_sbuf() function and put it into scsi_sense_only_sbuf(). This allows callers that don't use struct ccb_scsiio to easily utilize the printing routines. Revamp that function to handle descriptor sense and use the new sense fetching and printing routines.
Move scsi_extract_sense() into scsi_all.c, and implement it in terms of the new function, scsi_extract_sense_len(). The _len() version takes a length (which should be the sense length - residual) and can indicate which fields are present and valid in the sense data.
Add a couple of new scsi_get_*() routines to get the sense key, asc, and ascq only.
mly.c: Rename struct scsi_sense_data to struct scsi_sense_data_fixed.
sbp_targ.c: Use the new sense fetching routines to get sense data instead of accessing it directly.
sbp.c: Change the firewire/SCSI sense data transformation code to use struct scsi_sense_data_fixed instead of struct scsi_sense_data. This should be changed later to use scsi_set_sense_data().
ciss.c: Calculate the sense residual properly. Use scsi_get_sense_key() to fetch the sense key.
mps_sas.c, mpt_cam.c: Set the sense residual properly.
iir.c: Use scsi_set_sense_data() instead of building sense data by hand.
iscsi_subr.c: Use scsi_extract_sense_len() instead of grabbing sense data directly.
umass.c: Use scsi_set_sense_data() to build sense data.
Grab the sense key using scsi_get_sense_key().
Calculate the sense residual properly.
isp_freebsd.h: Use scsi_get_*() routines to grab asc, ascq, and sense key values.
Calculate and set the sense residual.

MFp4: Large set of CAM inprovements.
- Unify bus reset/probe sequence. Whenever bus attached at boot or later, CAM will automatically reset and scan it. It allows to remove duplicate code from many drivers. - Any bus, attached before CAM completed it's boot-time initialization, will equally join to the process, delaying boot if needed. - New kern.cam.boot_delay loader tunable should help controllers that are still unable to register their buses in time (such as slow USB/ PCCard/ CardBus devices), by adding one more event to wait on boot. - To allow synchronization between different CAM levels, concept of requests priorities was extended. Priorities now split between several "run levels". Device can be freezed at specified level, allowing higher priority requests to pass. For example, no payload requests allowed, until PMP driver enable port. ATA XPT negotiate transfer parameters, periph driver configure caching and so on. - Frozen requests are no more counted by request allocation scheduler. It fixes deadlocks, when frozen low priority payload requests occupying slots, required by higher levels to manage theit execution. - Two last changes were holding proper ATA reinitialization and error recovery implementation. Now it is done: SATA controllers and Port Multipliers now implement automatic hot-plug and should correctly recover from timeouts and bus resets. - Improve SCSI error recovery for devices on buses without automatic sense reporting, such as ATAPI or USB. For example, it allows CAM to wait, while CD drive loads disk, instead of immediately return error status. - Decapitalize diagnostic messages and make them more readable and sensible. - Teach PMP driver to limit maximum speed on fan-out ports. - Make boot wait for PMP scan completes, and make rescan more reliable. - Fix pass driver, to return CCB to user level in case of error. - Increase number of retries in cd driver, as device may return several UAs.

Prepare for future integration between CAM and newbus. xpt_bus_register now takes a device_t to be the parent of the bus that is being created. Most SIMs have been updated with a reasonable argument, but a few exceptions just pass NULL for now. This argument isn't used yet and the newbus integration likely won't be ready until after 7.0-RELEASE.

Remove Giant from CAM. Drivers (SIMs) now register a mutex that CAM will use to synchornize and protect all data objects that are used for that SIM. Drivers that are not yet MPSAFE register Giant and operate as usual. RIght now, no drivers are MPSAFE, though a few will be changed in the coming week as this work settles down.
The driver API has changed, so all CAM drivers will need to be recompiled. The userland API has not changed, so tools like camcontrol do not need to be recompiled.

The first of 3 major steps to move the CAM layer forward to using the CAM_NEW_TRAN_CODE that has been in the tree for some years now.
This first step consists solely of adding to or correcting CAM_NEW_TRAN_CODE pieces in the kernel source tree such that a both a GENERIC (at least on i386) and a LINT build with CAM_NEW_TRAN_CODE as an option will compile correctly and run (at least with some the h/w I have).
After a short settle time, the other pieces (making CAM_NEW_TRAN_CODE the default and updating libcam and camcontrol) will be brought in.
This will be an incompatible change in that the size of structures related to XPT_PATH_INQ and XPT_{GET,SET}_TRAN_SETTINGS change in both size and content. However, basic system operation and basic system utilities work well enough with this change.

- Providing fine-grained malloc statistic by replacing M_DEVBUF with module-specific malloc types. These should help us to pinpoint the possible memory leakage in the future. - Implementing xpt_alloc_ccb_nowait() and replacing all malloc/free based CCB memory management with xpt_alloc_ccb[_nowait]/xpt_free_ccb. Hopefully this would be helpful if someday we move the CCB allocator to use UMA instead of malloc().
