remove bs, a pc98-only driver
Change (almost) all references to tqh_first and tqe_next and tqe_prev to the correct TAILQ macros. Exceptions are contrib/ipfilter, which will be handled separately, and dev/misc/labpc, which makes some very wiered things and therefore needs much more care.
The cam_sim structure was being deallocated unconditionally by device driver detach routines. The problem with this is that part of the CAM bus structure may still be active (for example, with pending timeout()'s), and even though the bus, target, and device is freed, since the sim IS freed any accesses through the sim will hit 0xdeadc0de. This case most often occurs with USB UMASS devices. The CAM_XPT and CAM_SIM layer has been revamped. CAM_DEV_UNCONFIGURED is now accounted for in the device->refcount, and the cam_sim structure is now ref-counted as well. Additionally, the cam_simq* code which handles the device queues has been revamped to refcount as well, so shared device queues (raid and multi-channel devices) are not free()'d before all references have gone away. scsi_low free'd its cam_sim twice. Fixed. USB was improperly using M_NOWAIT. All M_NOWAIT instances have been renamed to M_INTWAIT.
remove __P() from this directory
kernel tree reorganization stage 1: Major cvs repository work (not logged as commits) plus a major reworking of the #include's to accomodate the relocations. * CVS repository files manually moved. Old directories left intact and empty (temporary). * Reorganize all filesystems into vfs/, most devices into dev/, sub-divide devices by function. * Begin to move device-specific architecture files to the device subdirs rather then throwing them all into, e.g. i386/include * Reorganize files related to system busses, placing the related code in a new bus/ directory. Also move cam to bus/cam though this may not have been the best idea in retrospect. * Reorganize emulation code and place it in a new emulation/ directory. * Remove the -I- compiler option in order to allow #include file localization, rename all config generated X.h files to use_X.h to clean up the conflicts. * Remove /usr/src/include (or /usr/include) dependancies during the kernel build, beyond what is normally needed to compile helper programs. * Make config create 'machine' softlinks for architecture specific directories outside of the standard <arch>/include. * Bump the config rev. WARNING! after this commit /usr/include and /usr/src/sys/compile/* should be regenerated from scratch.
Add the DragonFly cvs id and perform general cleanups on cvs/rcs/sccs ids. Most ids have been removed from !lint sections and moved into comment sections.
