linux: Exposes renderD nodes and chardev in sysfs
To allow normal users to render through the render device, we expose the
renderD node. This enables Wayland applications to use hardware
acceleration when running under the Linux emulator.
Additionally, libdrm and Mesa need to look up
/sys/dev/char/<major>:<minor> and <pcidev>/drm to identify the
corresponding renderer device (e.g., a renderD device). We expose this
path as well so that libdrm can locate the renderer.

hyperv: Fix single page invalidation path
A single page invalidation sets addr2 == 0. In the original code, it
falsely flush the whole address in non global pmap. However, the
kernel pmap are all PG_G, which means a single page flush will always be
staled and thus become invalid. As a result, we set parameter based on
their op in a new helper function instead of relying on args. This
affects only on AMD platform as Intel has their PTI implementation.

In the future we won't want to mask wake interrupts.
Once we can actually make use of GPIO interrupts on x86, we'll also want

mgb: Correct TX interrupt bit
The TX interrupt handler checked MGB_INTR_STS_RX(qidx) instead of

Because the driver does not use TX interrupts so there was no actual

bnxt_en: dcb: stop zeroing ETS and PFC config in bnxt_dcb_init()
bnxt_dcb_init() currently pushes all-zero ETS and PFC settings to
the firmware at every attach. This reserves bandwidth allocation
for RoCE traffic, which prevents L2 traffic from reaching line rate.
These settings should only be updated with valid values when the
RoCE driver is loaded. Therefore, we should stop programming them
during bnxt_dcb_init().

makefs/zfs: count "." in the link count and size of dataset roots
The root directory of a dataset is populated from an fsnode that is the
"." entry of the staging directory, and its children are the siblings of
that node, so the loop that computes the link count and the size of the
directory (which expects "." among the children, as the nodes of the
other directories have) never counts it. The link count of the root of
every dataset is one less than it should be (1 for an empty dataset
instead of 2, 19 instead of 20 for a root with 18 subdirectories), and
so is its size.
fts(3) trusts the link count of the directories of ZFS when called with
FTS_NOSTAT and FTS_PHYSICAL: it stops looking for subdirectories once it
has seen as many as the link count says, and does not descend into the
ones it did not look at. As a result find(1), and rm(1) when it does
not need to stat the entries, silently skip directories of a pool made
by makefs. On a root filesystem made by makefs, find / does not list
/etc at all.

if_bnxt: dcb: serialize HWRM sends and avoid freeing DMA bufs on timeout
Every _hwrm_send_message() call in bnxt_dcb.c ran without BNXT_HWRM_LOCK,
unlike the rest of the driver, letting concurrent HWRM commands race on
the shared MMIO doorbell and response buffer. Route single-shot sends
through the already-locked hwrm_send_message() wrapper, and wrap the
remaining send+response-read sequences in explicit BNXT_HWRM_LOCK/UNLOCK.
Also stop freeing the transient DMA buffers used for structured-data
get/set on ETIMEDOUT: a host-side timeout doesn't guarantee firmware
actually gave up, so a late completion could still DMA into memory
that's since been freed and reused. Leak the buffer instead in that case.

if_bnxt: port workqueue, task-queue, and synchronization kPIs to FreeBSD natives
- Replace Linux workqueue (struct workqueue_struct, bnxt_pf_wq) with a
FreeBSD taskqueue (bnxt_taskq) shared by every attached PF. bnxt_taskq
is created once at module load and destroyed once at module unload
(SYSINIT/SYSUNINIT on SI_SUB_KLD), matching the module-owned-taskqueue
idiom used elsewhere in the tree (e.g. sys/dev/cxgbe/t4_main.c's
reset_tq). This replaces an earlier lazy, per-attach/detach
create-or-reuse scheme guarded by a mutex and a "ready" flag, which
had a real race: bnxt_queue_sp_work()/bnxt_queue_fw_reset_work() and
bnxt_attach_pre() re-read the bnxt_taskq/bnxt_taskq_ready globals
outside the mutex right after the lazy-init call returned, so a
concurrent bnxt_detach() on another PF freeing the shared queue once
bnxt_num_pfs hit 0 could race a still-attached PF into enqueuing onto
a freed taskqueue. Tying the taskqueue's lifetime to the module
instead of to any one PF's attach/detach removes that race outright,
since the module can't unload while a PF is still attached.

htole16/32/64/le16toh/le32toh/le64toh throughout bnxt_hwrm.c and
the vf-event producer path in if_bnxt.c.
- Replace rmb()/wmb() interprocessor-ordering uses in bnxt_ulp.c

across CPUs) with atomic_thread_fence_acq()/atomic_thread_fence_rel();
keep wmb() for the HWRM doorbell/DMA ordering barrier in
_hwrm_send_message() (bnxt_hwrm.c), since atomic_thread_fence_rel()
compiles to a bare compiler barrier on amd64/i386 and does not order
the request-buffer store against the doorbell MMIO write.
