Add new kern.vt.slow_down tunable.
On a laptop with no other console devices than the screen, things
scroll of the screen faster than eye or camera can capture it.
This tunable slows the console down and makes it update synchronously,
so console output continues when timers or interrupts do not.

mlx5: Fix handling of port_module_event
Remove the array of port module status and instead save module status
and module number.
At boot, for each PCI function driver get event from fw about module
status. The event contains module number and module status. Driver
stores module number and module status.. When user (ifconfig) ask for
modules information, for each pci function driver first queries fw to
get module number of current pci function, then driver compares the
module number to the module number it stored before and if it matches
and module status is "plugged and enabled" then driver queries fw for
the eprom information of that module number and return it to the
caller.
In fact fw could have concluded that required module number of the
current pci function, but fw is not implemented this way. current
design of PRM/FW is that MCIA register handling is only aware of
modules, not the pci function->module connections. FW is designed to

mlx5e tls: Ensure all allocated tags have a hw context associated
Ensure all allocated tags have a hardware context associated.
The hardware context allocation is moved into the zone import
routine, as suggested by kib. This is safe because these zone
allocations are always done in a sleepable context.
I have removed the now pointless num_resources tracking,
and added sysctls / tunables to control UMA zone limits
for these tls tags, as well as a tunable to let the
driver pre-allocate tags at boot.

igc.4: Remove non-existent timer tunables
These were removed in a40ecb6f7405 because they do not apply to igc

dtrace: Add some more annotations for KMSAN
- Don't allow FBT and kinst to instrument the KMSAN runtime.
- When fetching data from the traced thread's stack, mark it as
initialized. It may well be uninitialized, but as dtrace permits
arbitrary inspection of kernel memory, it isn't very useful to raise
KMSAN reports.
- Mark data copied in from userspace as initialized, as we do for
copyin() etc. using interceptors.

Key code swapping between [<>] and [^°] key is enabled for all Apple ISO

keys presence.
usbdevs file is extended by several Apple keyboard models to support ISO

dtrace: Avoid excessive pcpu allocations
We were previously allocating MAXCPU structures for several purposes,
but this is generally unnecessary and is quite excessive, especially
after MAXCPU was bumped to 1024 on amd64 and arm64. We already are
careful to allocate only as many per-CPU tracing buffers as are needed;
extend this to other allocations.
For example, in a 2-vCPU VM, the size of a consumer state structure
drops from 64KB to 128B. The size of the per-consumer `dts_buffer` and
`dts_aggbuffer` arrays shrink similarly. Ditto for pre-allocations of
local and global D variable storage space.
