Attempting to retrieve an md_cval string from a kernel module with
kldxref would throw a offset error for modules created using lld, since
this value would be placed at the end of all allocated sections.
Add an ef_read_seg_string method to the ef interface, to allow reading

The original rtcin() and writertc() functions which do lock/unlock on each

When the fsck_ffs program cannot fully repair a file system, it will
output the message PLEASE RERUN FSCK. However, it does not exit with a
non-zero status in this case (contradicting the man page claim that it
"exits with 0 on success, and >0 if an error occurs." The fsck
rc-script (when running "fsck -y") tests the status from fsck (which
passes along the exit status from fsck_ffs) and issues a "stop_boot"
if the status fails. However, this is not effective since fsck_ffs can
return zero even on (some) errors. Effectively, it is left to a later
step in the boot process when the file systems are mounted to detect
the still-unclean file system and stop the boot.
This change modifies fsck_ffs so that when it cannot fully repair the
file system and issues the PLEASE RERUN FSCK message it also exits
with a non-zero status.
While here, the fsck_ffs man page has also been updated to document
the failing exit status codes used by fsck_ffs. Previously, only exit
status 7 was documented. Some of these exit statuses are tested for in
the fsck rc-script, so they are clearly depended upon and deserve
documentation.

[LV] Don't call recordVectorLoopValueForInductionCast for
newly-created IV from a trunc.
Summary:
This method is supposed to be called for IVs that have casts in their
use-def chains that are completely ignored after vectorization under
PSE. However, for truncates of such IVs the same InductionDescriptor
is used during creation/widening of both original IV based on PHINode
and new IV based on TruncInst.
This leads to unintended second call to
recordVectorLoopValueForInductionCast with a VectorLoopVal set to the
newly created IV for a trunc and causes an assert due to attempt to
store new information for already existing entry in the map. This is
wrong and should not be done.
Fixes PR35773.

Ths change consists of two parts.
geom_disk: deny opening a disk for writing if it's marked as
write-protected. A new disk(9) flag is added to mark write protected
disks. A possible alternative could be to add another parameter to d_open,
so that the open mode could be passed to it and the disk drivers could
make the decision internally, but the flag required less churn.
scsi_da: add a new phase of disk probing to query the all pages mode

If fdt_overlay_apply fails at some stage to apply the overlay to the base,
both the base and overlay may be in an inconsistent state (some fixups
applied, some phandles adjusted, some symbols merged). These can be bad for
a number of reasons, to include user frustration if some fixups applied and
not others. Fail a little safer by making a clean copy of the base FDT for
every overlay that we can simply discard if things go awry.
This also allows us the luxury of simply discarding overlays if we hit some
kind of memory limit or if they're malformed and extremely large for some
reason. We'll now leave a nice error message indicating that some overlays
could not be applied due to size restrictions and we apply what we can.
I note that our overlay implementation has some flaws that might still leave
your system in an unbootable state even if an overlay applies correctly;
please exercise caution in using overlays until we can swap it out for
libfdt's implementation.
