do not enable pci bridge decoding on resume until I/O windows are restored
PCI bus driver restores most but not all of a child PCI-PCI bridge
configuration. The bridge's I/O windows are restored by pcib driver and
that happens later in time. This can be problematic because the Command
register is restored before the windows are restored. If the firmware
programs the windows incorrectly or even does not program them at all,
then the bridge can start claiming I/O cycles that are not intended for
it. This will continue until the correct windows are restored.
I have observed this problem with a buggy BIOS where after resuming from
S3 an I/O port window of a PCI-PCI bridge was configured with zero base
and limit causing the bridge to claim 0x0 - 0xFFF port range. That
interfered with ACPI port access including ACPI PM Timer at port 0x808,
thus wreaking havoc in the time keeping.
The solution is to restore the Command register of PCI-PCI bridges after
the windows are restored in pcib driver. While here, I decided that for

Command register after their BARs are restored.

[net80211] Fix interrupted scan logic and ticks comparison
The scan task refactoring stuff circa 2014-2016 broke the blocking task
into a taskqueue with some async bits, but it apparently broke scans
being interrupted by traffic.
Notably - the new "field" SCAN_PAUSE sets both SCAN_INTERRUPT and SCAN_CANCEL,
and a bunch of existing code was checking for SCAN_CANCEL only and breaking
the scan. Unfortunately it was then (a) cancelling the scan entirely and
(b) not notifying userland that scan was done.
So:
* Update the calls to scan_end() to only pass in 1 (saying the scan is complete)
if SCAN_CANCEL is set WITHOUT SCAN_INTERRUPT. If both are set then yes,
the scan is interrupted, but it isn't canceled - it's just paused.
* Update the "did the scan flags change whilst the driver was called" logic
to check for canceled scans, not interrupted scans.
* The "scan done" logic now explicitly checks for either interrupted or
completed scans. This accounts for the situation where a scan is being
aborted via traffic but it ALSO happens to have finished (ie the last
channel was checked.)
This doesn't ENTIRELY fix scanning as the resume function is broken
due to incorrect ticks math. Thus, the second half of this patch
changes the ieee80211_ticks_*() macros to use int instead of long,
matching the logic that the TCP code does with ticks and handles
wrapping / negative ticks values. If cast to long then the wrapping
math wouldn't work right (ie, if ticks was actually negative,
ie, after the system has been up for a while.)
This allows contbgscan() to correctly calculate if a scan should
continue based on ticks and ic->ic_lastdata .

- Add the missing stage 2 attributes
- Use these in pmap_enter to create a new mapping
- Handle stage 2 faults
The vmid set is based on the current asid set that was generalised in

to reset the vmid set. This will need to call into EL2 and invalidate the
TLB.
The stage 2 attributes have been added. To simplify setting these fields
two new functions are added to get the memory type and protection fields.
These are slightly different on stage 1 and stage 2 tables. We then use
them in pmap_enter to set the new level 3 entry to be stored.
The D-cache on all entries is cleaned to the point of coherency. This is
to allow the data to be visible to the VM. To allow for userspace to load
code when creating a new executable entry an invalid entry is created. When
the VM tried to use it the I-cache is invalidated. As the D-cache has
already been cleaned this will ensure the I-cache is synchronised with the
D-cache.
When the hardware implements a VPIPT I-cache we need to either have the
correct VMID set or invalidate it from EL2. As the host kernel will have
the wrong VMID set we need to call into EL2 to clean it. For this a second
function pointer is added that is called when this invalidation is needed.

cannot be linked against, and exported from the private namespace from rtld.
Consumers are required to use dlsym(3). For instance, for
_rtld_version_laddr_offset, user should do
ptr = dlsym(RTLD_DEFAULT, "_rtld_version_laddr_offset")
or even
ptr = dlvsym(RTLD_DEFAULT, "_rtld_version_laddr_offset",
"FBSDprivate_1.0");
Non-null ptr means that the change is present.
Also add _rtld_version__FreeBSD_version indicator to report the
headers version used at time of the rtld build.

Update ENA driver version to v2.2.0
Driver version upgrade is connected with support for the new device
fetures, like Tx drops reporting or disabling meta caching.
Moreover, the driver configuration from the sysctl was reworked to
provide safer and better flow for configuring:
* number of IO queues (new feature),
* drbr size on Tx,
* Rx queue size.
Moreover, a lot of minor bug fixes and improvements were added.
