We need to be careful to not promote or demote the memory containing
the per-CPU structures as the exception handlers will dereference it
so any time it's invalid may cause recursive exceptions.
Add a new pmap function to set a flag in the pte marking memory that
cannot be promoted or demoted and use it to mark pcpu memory.

Release Notes for "Chelsio Unified Wire 3.17.0.0 for Linux" dated
2022-07-29.
Fixes

BASE:
- Enabled all MA parity interrupt bits.
- Use config file value to override number of rx channel. nrxch=1 was not
handled in the firmware.
- Replaced read only registers with new registers EDC_H_BIST_USER_WDATA0,
EDC_H_BIST_USER_WDATA1 and EDC_H_BIST_CMD_LEN to dump the uP memory parity
error status registers.
- 10G simplex module support enabled.

For TSF and beacon generation, each STA has to start its local TSF timer
and sends beacon frames when it reaches the state IEEE80211_S_RUN.
The TSF timer will be used for IBSS merge and beacon frame transmission.
The TSF timer is kept in the HAL of wtap(4). It is working by
continuously updating its value on timer interrupt simulated
by callout_reset().
When receiving beacons, the STA will be merged into the IBSS if
- the STA has the same SSID as the beacon sender
- the STA's TSF timer is smaller than the beacon sender's TSF timer.
After the merging process, the younger STA will be in the IBSS
created by the older STA and the younger STA stops sending beacon
frames. So beacon frames will always be sent by the oldest STA
in IBSS.

When in the hpts path, we need to handle BPF filters since aggregated
packets do not pass up the stack in the normal way. This is already
done for most interfaces, but lagg needs special handling. This is
because packets received via a lagg are passed up the stack with
the leaf interface's ifp stored in m_pkthdr.rcvif.
To handle lagg packets, we must identify that the passed rcvif is
currently a lagg port by checking for IFT_IEEE8023ADLAG or
IFT_INFINIBANDLAG (since lagg changes the lagg port's type to that
when an interface becomes a lagg member). Then we need to find the
lagg's ifp, and handle any BPF listeners on the lagg.
Note: It is possible to have multiple BPF filters, one on a member
port and one on the lagg itself. That is why we have to have 2
checks and 2 ETHER_BPF_MTAPs.

The function ffs_vgetf() is used to find or load UFS inodes into a
vnode. It first looks up the inode and if found in the cache its
vnode is returned. If it is not already in the cache, a new vnode
is allocated and its associated inode read in from the disk. The
read is done even for inodes that are being initially created.
The contents for the inode on the disk are assumed to be empty. If
the on-disk contents had been corrupted either due to a hardware
glitch or an agent deliberately trying to exploit the system, the
UFS code could panic from the unexpected partially-allocated inode.
Rather then having fsck_ffs(8) verify that all unallocated inodes
are properly empty, it is easier and quicker to add a flag to
ffs_vgetf() to indicate that the request is for a newly allocated
inode. When set, the disk read is skipped and the inode is set to
its expected empty (zero'ed out) initial state. As a side benefit,
an unneeded disk I/O is avoided.

into ffs_sbsearch() to allow use by other parts of the system.
Historically only fsck_ffs(8), the UFS filesystem checker, had code
to track down and use alternate UFS superblocks. Since fsdb(8) used
much of the fsck_ffs(8) implementation it had some ability to track
down alternate superblocks.
This change extracts the code to track down alternate superblocks
from fsck_ffs(8) and puts it into a new function ffs_sbsearch() in
sys/ufs/ffs/ffs_subr.c. Like ffs_sbget() and ffs_sbput() also found
in ffs_subr.c, these functions can be used directly by the kernel
subsystems. Additionally they are exported to the UFS library,
libufs(8) so that they can be used by user-level programs. The new
functions added to libufs(8) are sbfind(3) that is an alternative
to sbread(3) and sbsearch(3) that is an alternative to sbget(3).
See their manual pages for further details.
The utilities that have been changed to search for superblocks are
dumpfs(8), fsdb(8), ffsinfo(8), and fsck_ffs(8). Also, the prtblknos(8)
tool found in tools/diag/prtblknos searches for superblocks.
The UFS specific mount code uses the superblock search interface
when mounting the root filesystem and when the administrator doing
a mount(8) command specifies the force flag (-f). The standalone UFS
boot code (found in stand/libsa/ufs.c) uses the superblock search
code in the hope of being able to get the system up and running so
that fsck_ffs(8) can be used to get the filesystem cleaned up.
The following utilities have not been changed to search for
superblocks: clri(8), tunefs(8), snapinfo(8), fstyp(8), quot(8),
dump(8), fsirand(8), growfs(8), quotacheck(8), gjournal(8), and
glabel(8). When these utilities fail, they do report the cause of
the failure. The one exception is the tasting code used to try and
figure what a given disk contains. The tasting code will remain
silent so as not to put out a slew of messages as it trying to taste
every new mass storage device that shows up.

The BIOS loader operates in a very constrained environment. The messages
for the super block integrity tests take up about 12k of space. Compile
them out for the BIOS loader, while leaving it intact for all other
loaders that aren't space constrained. These aren't used in the 'super
tiny' *boot* programs, so no adjustment is needed there.
We reply on the fact that (a) i386 doesn't support 32-bit UEFI booting
and (b) LIBSA_CPUARCH is "i386" when building on both i386 and when
we're building the 32-bit libsa32 library.
This saves about 12k of space for this constrained envrionment and will
take a bit of the pressure off some machines where the loader has grown
too big for their BIOS (see comments in i386/loader/Makefile for
details).
