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.

amdgpio: Suspend routine
Mask all interrupts when suspending and warn when there are unserviced
interrupts which might block entry to S0i3.
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
to unmask relevant pins when resuming.

mgb: Correct TX interrupt bit
The TX interrupt handler checked MGB_INTR_STS_RX(qidx) instead of
MGB_INTR_STS_TX(qidx) -- presumably a copy-paste issue.
Because the driver does not use TX interrupts so there was no actual
issue in practice.

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().

ctf*: exit with error upon terminate()
The initial port of the CTF tools had a FreeBSD-specific patch to print
the termination message but exit with a 0 status, with a goal of getting
as much to build as possible and silently ignoring any issues.
We're now past the point where silently ignoring failures makes sense.
Any future issues need to be found and addressed.

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.

arm64/vmm: vgic_v3: Set EOI for level-triggered interrupts
ICH_LR_EL2 bit 41 (EOI) determines whether a maintenance interrupt will
be asserted if the interrupt identified by the LR's vINTID is
deactivated. For level-triggered interrupts, that maintenance interrupt
is necessary for the host to resample the current level once the
interrupt is deactivated.
Set the EOI bit when flushing level-triggered interrupts into LRs.
