Create a new 32-bit fs_flags word in the superblock. Add code to move

2002-11-27T02:18:58Z

the old 8-bit fs_old_flags to the new location the first time that the filesystem is mounted by a new kernel. One of the unused flags in fs_old_flags is used to indicate that the flags have been moved. Leave the fs_old_flags word intact so that it will work properly if used on an old kernel. Change the fs_sblockloc superblock location field to be in units of bytes instead of in units of filesystem fragments. The old units did not work properly when the fragment size exceeeded the superblock size (8192). Update old fs_sblockloc values at the same time that the flags are moved.

Eliminate references to defunct kernel tunables.

It seems that the only problem with UFS2 booting on i386 is the 64bit

divide/remainder calls. For reasons not resolved, compiling the relevant routines from libkern into boot2 results in stack corruption. Do the simple thing: Don't use 64bit divide/remainder operations. Sponsored by: DARPA & NAI Labs

Move the definition of UFS1_ONLY into the Makefiles where it belongs.

Fix device hints entry for disabling acpi(4). This also should fix the arbitration with apm(4) when both drivers are enabled. Note that your /boot/device.hints needs to be updated if you want to stop auto-loading acpi.ko or disable acpi(4).

Actually remove the stale a.out kld support. This is the stuff that was
