libsysdecode: use local sysdecode.h
Replace <sysdecode.h> with "sysdecode.h" so local builds use the in-tree header
in lib/libsysdecode instead of a stale installed copy in /usr/include, avoiding
build failures after updating sysdecode.h.

xhci: Fix packet xfer larger than 64kb
Previously, multiple frames of xfers are split into many tds. In the
refactor process, we forget to consider this. The td builder is already
allocate with enough numbers of tds. What we need to do is to fill the
normal trbs for muiltiple tds when building trbs.

mkimg: Add ms-basic-data alias for GPT
While preparing GPT-schemed RaspberryPi images for the NanoBSD
Reimagined GSoC 2026 project, a discrepancy was identified between
mkimg(1) and gpart(8) regarding Microsoft Basic Data partitions (GUID
!ebd0a0a2-b9e5-4433-87c0-68b6b72699c7).
Currently, mkimg(1) relies on the MBR-centric name "ntfs" to identify
this partition type under the GPT scheme. Conversely, gpart(8)
identifies this type as "ms-basic-data".
To allow automation scripts (such as those consuming from gpart backup)
to use a common partition type across tools, add ALIAS_MS_BASIC_DATA as
a valid alias.
This is part of a larger effort to avoid a custom, MBR-based image
generation logic for embedded SoCs like the Raspberry Pi, standardizing
on GPT layouts across all supported FreeBSD embedded devices.

cam/cd: avoid integer divide fault in cdstart()
If something goes very badly (e.g. forcibly removing a medium while
the OS tries to start it), this could end up in params.blksize being 0
(and params.disksize 1). Avoid an integer divide fault, panicking the
kernel, by bailing out before.

mt76: disable debugfs due to missing piece still in review
Until D57524 is not reviewed and committed we will have a missing
function declaration which prevents us to compile (in) debugfs for
mt76 core and mt7921. Temporary disable debugfs again.

mt76: further adjust debugfs compile time options
The debugfs options between the various modules (core and chipsets)
are not 100% de-coupled. This means we may run into unresolveable
symbols at load time of the modules if we enable certain options
generally or for core but not for the chipset.
For now: always build the core module with debugfs support.
Migrate the CONFIG_MAC80211_DEBUGFS flag into the Makefile of each
chipset so we can individually turn it on.

LinuxKPI: page pool updates and add to the build
Split implementation out from the header files.
This "page pool" is the very minimalistic version we need in order to
support packets on mt76.
We allocate the page pool in order to have the meta data available of
which we only make limited use.
This implementation does no pooling, it does no page fragments for now,
it always hands out a full page and frees it upon return.
It is written in a way that it can be in the tree before the 'struct page'
work it depends on has landed in order to reduce friction for people who
want to try mt7921 (or others later) upfront. We use the same #ifdef
as in the struct page work for that reason so one knob will turn everything
on or off.
Once the struct page work has landed and settled we can start filling this
with more complexity.

LinuxKPI: page.h: resort lines
Two of the "page macros" can be abstracted elsewhere in the upcoming

stay.

LinuxKPI: prefer struct page [*] over struct vm_page[_t]
LinuxKPI is based on Linux 'struct page' which is currently aliased
to struct vm_page. Upcoming changes may change that so start using
'struct page *' instead vm_page_t to make future changes transparent.
This is a continuation of 9e9c682ff3a1 and should be a NOP.

LinuxKPI: move clear_page() within the linux/page.h file
clear_page() would normally live in asm/page.h but adding the file
and fixing the dependencies would be too much for a single line.
Move the function to the end of the file with a clear separator
and make it clear that it does not operate on a 'struct page'
but on a page address by changing the argument name and leaving
a comment.
The function is currently used by at least mthca(4) as the only
in-tree consumer, and drm-kmod ttm_pool.c.

dma_addr_t is a vm_paddr_t which is a uint of some width. Rather than

Comparing the addresses of different storage for the same dma handle

LinuxKPI: 802.11: always lock around (*set_{frag,rts}_threshold)
We would lock the downcalls during normal operation but not during
vap (vif) creation as there was no need for locking.
Add the missing locking there as drivers seem to always expect it
(by assertion) and cannot distinguish between state.
Add the assertions to the downcalls as we need both of them locked
and both of them can sleep.
