Diskdrivers and similar stuff below specfs::strategy() should no longer need to include unless they need caching of data. Still a few bogus uses of struct buf to track down. Repocopy by: peter

Simplify cdevsw registration.

The cdevsw_add() function now finds the major number(s) in the struct cdevsw passed to it. cdevsw_add_generic() is no longer needed, cdevsw_add() does the same thing. cdevsw_add() will print an message if the d_maj field looks bogus. Remove nblkdev and nchrdev variables. Most places they were used bogusly. Instead check a dev_t for validity by seeing if devsw() or bdevsw() returns NULL. Move bdevsw() and devsw() functions to kern/kern_conf.c Bump __FreeBSD_version to 400006 This commit removes: 72 bogus makedev() calls 26 bogus SYSINIT functions if_xe.c bogusly accessed cdevsw[], author/maintainer please fix. I4b and vinum not changed. Patches emailed to authors. LINT probably broken until they catch up.

This commit should be a extensive NO-OP:

Reformat and initialize correctly all "struct cdevsw". Initialize the d_maj and d_bmaj fields. The d_reset field was not removed, although it is never used. I used a program to do most of this, so all the files now use the same consistent format. Please keep it that way. Vinum and i4b not modified, patches emailed to respective authors.

During probe, the page lockdown code in dpt_control.c does some

1999-05-11T11:03:18Z

bad math: it does not handle page-boundary conditions, and will not end up mapping all of the requested addresses. This will cause a panic: page fault during probe on some systems. I have a machine that will panic every time (when using the dpt driver) on kernel probe when there are 5 drives installed. When there are 4 drives, it is fine. Fix is to always allocate/deallocate an extra page. There is also a bonus splx() fix on an early error return. Submitted by: Mark J. Taylor PR: 9367
