- When userland changes EXT_CSD, update the kernel copy before using
relevant EXT_CSD bits in mmcsd_switch_part().
The resize test used bsdlabel(8), which is not available on all
architectures. Change it to use gpart(8) instead, which should be available
everywhere.

Overlays were previously not applied when U-Boot provides FDT or EFI
provides FDT, only when we load FDT from /boot/dtb given name from U-Boot.
Make all three paths lead to loading fdt_overlays and applying them, so that
fdt_overlays can be expected to Just Work.

This change mostly reverts r293436, which introduced the bug due to a belief
that geli(8) would allocate md(4) devices by itself. However, that belief is
incorrect. Instead of using linear probing to find available md(4) numbers,
it's best to use the existing attach_md function.

them generate interrupts when actually using (re-)tuning.
- Also disable all interrupts except SDHCI_INT_DATA_AVAIL ones while

This adds HardenedBSD which is a pseudo-fork of FreeBSD. It hasn't had a
release yet, but does does have active users and a community. As such
document it as a branch off of FreeBSD-stable. Ideally this adds enough
space so that future releases are easy enough to add.
Resolve a minor mismatch: TXP_CMD_READ_VERSION instead of
TXP_CMD_VERSIONS_READ.
Curiously the later is defined but not used in OpenBSD.

draft of a never-finalized standard (CHRP) and is irrelevant in practice
on FreeBSD since we load the kernel with loader(8) on Open Firmware
platforms anyway. Moreover, loader(8), which is directly loaded by Open
Firmware, has never had an equivalent note.

Fix for remainder overflow, when in rare cases adding remainder to divider
exceeded 1 and turned the total to 1000 in final formatting, taking up
the space for the unit character.
The fix continues the division of the original number if the above case
happens -- added the appropriate check to the for loop performing
the division. This lowers the value shown, to make it fit into the buffer
space provided (1.0M for 4+1 character buffer, as used by ls).
Add test case for the reported bug and extend test program to support
providing buffer length (ls -lh uses 5, tests hard-coded 4).

(now: Interrupt_Index[15]) and assigned the previously reserved bits
55:48 (Interrupt_Index[14:0] goes into 63:49 while Destination Field
used 63:56 and bit 48 now is Interrupt_Format) in the IO redirection
tables (see the VT-d specification, "5.1.5.1 I/OxAPIC Programming").
Thus, when not using interrupt remapping, ensure that all previously
reserved bits in the high part of the RTEs are zero instead of doing
a read-modify-write for their Destination Field bits only.
Otherwise, on machines based on Apollo Lake and its derivatives such
as Denverton, typically some of the previously preserved bits remain
set after boot when not employing interrupt remapping. The result is
that INTx interrupts are not getting delivered.
Note: With an AMD IOMMU, interrupt remapping apparently bypasses the
IO APIC altogether.

In the case of a simple dtbo where fragment uses target-path and the overlay
contains no references, /__fixups__ will not be included by either our dtc
or dtc from ports, but the file still has valid fragments to be applied.
Additional testing found that /__symbols__ might also be omitted if it's
empty, which is not necessarily an error.

fdt_load_dtb_overlays was written to unload previous overlay when a new

iterate over all .dtbo's currently loaded and apply them one-by-one. Correct
fdt_load_dtb_overlays to stop dropping valid overlays that were previously

netinet6/ip6_id.c: niels kindly dropped clause 3/4 from the license.
I was looking at the wrong file. There is an important merge that must be
done before I can bring this change.
This file is supposed to be based on the OpenBSD CVS v1.6 but checking
the OpenBSD repository the license had already dropped the 2&3 clasues by
then. Catch up with the licensing.

Most notable, other than some style issues:
CVS 1.11:

The existing algorithm in procfs_map() to calculate count of resident
pages in an entry is too primitive, resulting in too long run time for
large sparse mapping entries. Re-use the kern_proc_vmmap_resident()
from kern_proc.c which only looks at the existing pages in the
iterations.
Also, this makes procfs to honor kern.proc_vmmap_skip_resident_count,
if user does not need this information.
