- If RB_ASKNAME, prompt for the dump device, defaulting to
partition 'b' of the root device, if the root device is a disk.
- Else, if dumpspec is set to "none", do not configure a dump device.
- Else, if dumpspec is set by config(8), attempt to use that device.
- Else, dumpspec is wildcarded or unspecified; if the root device is
a disk, select partition b. (which was the previous default dump
partition)
Note, dumps to a local disk now work even if root is on nfs.
so that if the drop to spl0() causes another panic (e.g. because there's

__VM_PMAP_HACK is defined (for temporary compatibility).
The __VM_PMAP_HACK code should be removed after all the

fill the socket's creation time into the stat structure's st_[acm]time fields:
POSIX requires this behavior for pipe(2). N.B.: updating the st_[am]time fields
when reading/writing the pipe is neither required nor implemented, though.
(1): "substart == ex->ex_end" and "subend == ex->ex_start"
are completely legal parameters for extent_alloc_subregion()
(2): "(subend - substart) + 1" can cause an overflow if the whole
numeric range is covered by the extent.

1) Eliminate all of the null component name special cases; handle runs of
slashes and leading and trailing slashes completely differently.
2) Return ENOENT when doing a lookup through an empty symlink.
3) Enforce that we're doing a lookup through a directory in in chdir() and
lookup() rather than in foo_lookup().

have any signals delivered while exiting, so this should be okay. Change the
test for a traced process in wait4() to exclude a process that was started by
the debugger; in this case, only one SIGCHLD should be delivered.
