* In uvm Chuck decided backing store would not be allocated proactivelyderaadt2017-12-111-7/+16
| | | | | | | | | | | | | | | | | | | | | | for blocks re-fetchable from the filesystem. However at reboot time, filesystems are unmounted, and since processes lack backing store they are killed. Since the scheduler is still running, in some cases init is killed... which drops us to ddb [noted by bluhm]. Solution is to convert filesystems to read-only [proposed by kettenis]. The tale follows: sys_reboot() should pass proc * to MD boot() to vfs_shutdown() which completes current IO with vfs_busy VB_WRITE|VB_WAIT, then calls VFS_MOUNT() with MNT_UPDATE | MNT_RDONLY, soon teaching us that *fs_mount() calls a copyin() late... so store the sizes in vfsconflist[] and move the copyin() to sys_mount()... and notice nfs_mount copyin() is size-variant, so kill legacy struct nfs_args3. Next we learn ffs_mount()'s MNT_UPDATE code is sharp and rusty especially wrt softdep, so fix some bugs adn add ~MNT_SOFTDEP to the downgrade. Some vnodes need a little more help, so tie them to &dead_vnops. ffs_mount calling DIOCCACHESYNC is causing a bit of grief still but this issue is seperate and will be dealt with in time. couple hundred reboots by bluhm and myself, advice from guenther and others at the hut

* Restore "print" in ddb; add "pp[rint]" for pretty-printinguwe2017-08-142-5/+6
| | | | | | | | | | | Changing the "print" command to use db_ctf_pprint_cmd() broke all documented uses and "examine" does not allow printing variables, or individual registers. For now it is better to leave the "print" command intact, and in sync with the ddb(4) man page, but we still want "pp[rint]" to replace the "print" command when it works better. ok mpi@
