Pull in r322473 from upstream llvm trunk (by Andrei Elovikov):
[LV] Don't call recordVectorLoopValueForInductionCast for
newly-created IV from a trunc.
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.

This should fix "Vector value already set for part" assertions when
building the net/iodine and sysutils/daa2iso ports.

Fix booting on some arm64 systems after r327879 by fixing the call to
utf8_to_ucs2 in boot1.efi. We need to initialise the ucs2 output string
so it will allocate space, and use the return value to determine if the
call was successful.

Convert the x86 RTC driver to use new validated BCD<->timespec conversions.
New common routines were added to kern/subr_clock.c for converting between
calendrical time expressed in BCD and struct timespec. The new functions
return EINVAL on error, as expected when the clock hardware does not provide

geom_disk / scsi_da: deny opening write-protected disks for writing
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
sense page. We can determine if the disk is write protected using bit 7
of the device specific field in the mode parameter header returned by

Move the pmap-specific code in copyinout.c that gets pointers to userland
buffers into a new pmap-module function pmap_map_user_ptr() that can
be implemented by the respective modules. This is required to implement
non-segment-based AIM-ish MMU systems such as the radix-tree page tables
introduced by POWER ISA 3.0 and present on POWER9.

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
