HBSD: ssh client: Disable compression by default
With commit b7961aade549f05f62d65b0906db495b9423c940, HardenedBSD
hardened the server-side sshd configuration.
This commit follows the same suit by hardening at least some of the same
variables on the client's side.

snd_emu10kx: Make sure the block count and size cover the whole buffer
The playback voices always loop over the whole EMU_PLAY_BUFSZ buffer,
but emupchan_setblocksize() only recorded the new block size and left
the block count as it was set up by emu_vinit(). The blocks then no
longer covered the whole buffer, and the part they left out was played
without ever being written to, which became audible as distortion once
playback started going through a virtual channel.
Resize the buffer, so that the block count and size always cover it.

(cherry picked from commit a7258157e1a20957af23332814197ea723f5778d)
video(4): wake the kqueue knote when a buffer completes
selwakeup() only wakes select/poll waiters; it does not notify the kqueue
knote registered on the device, so EVFILT_READ never fired when a frame
became available.
asmc.4: clean up/modernize manpage
- sysutils/ataidle is no more: it was superseded by camcontrol(8).
- Sort the models table alphabetically.
- Use the SPDX License ID instead of the longhand licensing tort in the
manpage header.
- Note that the driver has been heavily modified in 15.1 and later to
support additional platforms and functionality.
- Trim down SYNOPSIS.

apple_bce.4: add a basic manpage describing the driver
This new manpage describes what the apple_bce driver services, how the
driver is configured, and what Apple models the driver claims to
support.

nfscl: Yet more fixes for the NFS over RDMA client glue
Yet again. I was trying to make the svc_vc_backchannel()
operations do double duty and be used by the clnt_rdma.c code
as well. It got too messy, so this reverts svc_vc.c back to
its pre-glue form and adds the small changes needed to support
a separate set of svc_rdma_backchannel_xxx() functions.
This commit should not affect non-RDMA behaviour.

acpi_cpu: only report unmapped processor objects enabled in the MADT
Firmware expose a DSDT sized for the largest SKU of the platform,
so a verbose boot prints an "ignored" line for every vacant
processor slot. A vacant slot has no enabled MADT entry; a CPU that
failed to come online does.

intel/intelpmc: Add Intel PMC Core driver
Add driver for Intel Power Management Controller (PMC) found on Sunrise Point PCH chipsets.
This device exposes S0ix sleep state residency counters and power management status.
Sysctls provided:
dev.intelpmc.0.slp_s0_residency_us - Time in deepest sleep (us)
dev.intelpmc.0.ltr_ignore - LTR ignore mask
dev.intelpmc.0.pm_cfg - PM configuration register
dev.intelpmc.0.pm_sts - PM status register
dev.intelpmc.0.access_denied - Firmware lock status
Supported devices for now:
- Sunrise Point-LP (0x9D21)
- Sunrise Point-H (0xA121)
Note: Later PCH generations (Cannon Lake, Tiger Lake, ect.) have different PMC register layouts according to the datasheet and would need per-generation tables.
I avoided adding untested hardware in case they have a quirk.

nvme: reject namespaces formatted with metadata
The active LBA format's MS field was never examined. I/O to a
metadata-formatted namespace carries neither interleaved metadata
nor MPTR, so every command is malformed, yet the namespace attaches
as a disk with the wrong sector size.

tpm_tis: Quiesce interrupts before registering a handler
The current interrupt path uses the IRQ resource value directly as the
LPC SIRQ selector in TPM_INT_VECTOR and already restricts it to 1 through
15. This is a driver limitation: a parent interrupt number need not equal
an LPC SIRQ channel, and SPI TPMs can use a separate parallel interrupt.
On the reported system with ACPI IRQ 45, the existing range check runs
after handler registration and returns before disabling firmware interrupt
delivery. This can leave a polling device with a handler on an asserted
source.
Disable and verify interrupt delivery before registering a handler or
starting common TPM services. Preserve the existing range policy, using
polling without registering a handler for routes rejected by that check,
and release their IRQ resources. Keep a failed setup's potentially stale
output cookie out of the device state; the interrupt framework may
already have removed that handler.

LinuxKPI: Add dma_length field to struct scatterlist
On Linux `dma_length` field of `struct scatterlist` is present on the
arches where DMA mapping code is able to coalesce adjacent segments
of physical address space. It contains total length of coalesced
segments while `length` field contains non-coalesced length of each
segment. On other arches `dma_length` is aliased to `length` field with
`sg_dma_len` macro. As FreeBSD does not merge scatterlist segments it
do not have `dma_length` field. It is appered that at least i915kms
driver depends on existence of `dma_length` field.
Add the field and disable it by default. To enable add to Makefile
.if ${MACHINE_CPUARCH} == "i386" || ${MACHINE_CPUARCH} == "amd64" || \\
${MACHINE_CPUARCH} == "aarch64" || ${MACHINE_CPUARCH} == "powerpc"
CFLAGS+= -DCONFIG_NEED_SG_DMA_LENGTH
