upstream it seems).
The tlv variable was changed to a pointer but the advancement of the data pointer
was left as sizeof(tlv). While the sizeof the (now) pointer equals the
sizeof 2 x uint32_t (size of the struct) on 64bit platforms, on 32bit platforms
the size of the advancement of the data pointer was wrong leading to
firmware load issues.
Correctly advance the data pointer by the size of the structure and not by
the size of a pointer.

ccr reuses the control queue and first rx queue from the first port on
each adapter. The driver cannot send requests until those queues are
initialized. Refuse to create sessions for now if the queues aren't
ready. This is a workaround until cxgbe allocates one or more
dedicated queues for ccr.

o In vm_pager_bufferinit() create pbuf_zone and start accounting on how many
pbufs are we going to have set.
In various subsystems that are going to utilize pbufs create private zones
via call to pbuf_zsecond_create(). The latter calls uma_zsecond_create(),
and sets a limit on created zone. After startup preallocate pbufs according
to requirements of all pbuf zones.
Subsystems that used to have a private limit with old allocator now have
private pbuf zones: md(4), fusefs, NFS client, smbfs, VFS cluster, FFS,
swap, vnode pager.
The following subsystems use shared pbuf zone: cam(4), nvme(4), physio(9),
aio(4). They should have their private limits, but changing that is out of
scope of this commit.
o Fetch tunable value of kern.nswbuf from init_param2() and while here move
NSWBUF_MIN to opt_param.h and eliminate opt_swap.h, that was holding only
this option.
Default values aren't touched by this commit, but they probably should be
reviewed wrt to modern hardware.
This change removes a tight bottleneck from sendfile(2) operation, that
uses pbufs in vnode pager. Other pagers also would benefit from faster
allocation.

Family 15h is a bit of an oddball. Early models used the same temperature
register and spec (mostly[1]) as earlier CPU families.
Model 60h-6Fh and 70-7Fh use something more like Family 17h's Service
Management Network, communicating with it in a similar fashion. To support
them, add support for their version of SMU indirection to amdsmn(4) and use
it in amdtemp(4) on these models.
While here, clarify some of the deviceid macros in amdtemp(4) that were
added with arbitrary, incorrect family numbers, and remove ones that were
not used. Additionally, clarify intent and condition of heterogenous
multi-socket system detection.
[1]: 15h adds the "adjust range by -49°C if a certain condition is met,"
which previous families did not have.

Issue:
ocs_fc(4) driver panics. It's induced by setting the port_state
sysctl to offline, then online, then offline, then online, and so
forth and so on in rapid succession.
Reason:
While we set the port_state to online fc discovery will start and OS
is enumerating the target discs by calling ocs_action(), then set the
port state to "offline" which deletes domain/sport/nodes.
In ocs_action()->XPT_GET_TRAN_SETTINGS we are accessing the remote
node which can be invalid to get the wwpn, wwnn and port.
Fix:
Removed accessing of remote node and domain in some ocs_action() cases.
Populated the required values from ocs_fcport.
This removes the dependency of node and domain structures while
processing XPT_PATH_INQ and XPT_GET_TRAN_SETTINGS.
We will invalidate the target entries after the device lost
timeout(30 seconds).

- Remove macros that covertly create epoch_tracker on thread stack. Such
macros a quite unsafe, e.g. will produce a buggy code if same macro is
used in embedded scopes. Explicitly declare epoch_tracker always.
- Unmask interface list IFNET_RLOCK_NOSLEEP(), interface address list
IF_ADDR_RLOCK() and interface AF specific data IF_AFDATA_RLOCK() read
locking macros to what they actually are - the net_epoch.
Keeping them as is is very misleading. They all are named FOO_RLOCK(),
while they no longer have lock semantics. Now they allow recursion and
what's more important they now no longer guarantee protection against
their companion WLOCK macros.
Note: INP_HASH_RLOCK() has same problems, but not touched by this commit.
This is non functional mechanical change. The only functionally changed
functions are ni6_addrs() and ni6_store_addrs(), where we no longer enter
epoch recursively.

done on the old keyboard and then do the corresponding number of grabs
on the new keyboard.
This fixes a race that can leave the system with a non-functioning
keyboard. It goes like this...
- The bios claims there is an AT keyboard, atkbd attaches.
- SI_SUB_INT_CONFIG_HOOKS runs.
- USB probes devices. Devices begin attaching, including disks.
- GELI prompts for a password for a just-attached disk, which results
in a cngrab() while atkbd is the keyboard.
- A USB keyboard attaches.
- vt_upgrade() runs and switches the keyboard to the new USB keyboard,
but because cngrab was never called for it, it's not activated and
keystrokes are ignored.
- Now there is no functional keyboard and no way to get one; even
plugging in a different USB keyboard doesn't help, because the console
is still grabbed, still waiting for a GELI pw.

front-end doesn't support SDMA or the latter implements a platform-
specific transfer method instead. While at it, factor out allocation
and freeing of SDMA resources to sdhci_dma_{alloc,free}() in order to
keep the code more readable when adding support for ADMA variants.
o Base the size of the SDMA bounce buffer on MAXPHYS up to the maximum
of 512 KiB instead of using a fixed 4-KiB-buffer. With the default
MAXPHYS of 128 KiB and depending on the controller and medium, this
reduces the number of SDHCI interrupts by a factor of ~16 to ~32 on
sequential reads while an increase of throughput of up to ~84 % was
seen.
Front-ends for broken controllers that only support an SDMA buffer
boundary of a specific size may set SDHCI_QUIRK_BROKEN_SDMA_BOUNDARY
and supply a size via struct sdhci_slot. According to Linux, only
Qualcomm MSM-type SDHCI controllers are affected by this, though.
Requested by: Shreyank Amartya (unconditional bump to 512 KiB)
o Introduce a SDHCI_DEPEND macro for specifying the dependency of the
front-end modules on the sdhci(4) one and bump the module version
of sdhci(4) to 2 via an also newly introduced SDHCI_VERSION in order
to ensure that all components are in sync WRT struct sdhci_slot.
o In sdhci(4):
- Make pointers const were applicable,
- replace a few device_printf(9) calls with slot_printf() for
consistency, and
- sync some local functions with their prototypes WRT static.
Previous code typically crashed in case of NVMe device unplug or even clean
detach while some I/Os are still in flight. To fix this the new code calls
disk_gone() and waits for confirmation of all references gone before calling
disk_destroy(), freeing other resources and allowing controller detach.
While there, fix disk lists locking and reimplement unit numbers assignment.

Due to hardware errata in Aero controllers, reads to certain
fusion registers could intermittently return all zeroes.
This behavior is transient in nature and subsequent reads will return
valid value.
Fix:
For Aero controllers, any read will retry the read operations
from certain registers for maximum three times, if read returns zero.

2. Driver will use 64 bit request descriptor to fire IOC INIT.
3. If Aero firmware supports 32 bit atomic descriptor, then only driver will use it
otherwise driver will use 64 bit request descriptor.
For rest of adapters(Ventura, Invader and Thunderbolt), driver will use 64 bit request
descriptors only.
