e975d1b725 linux(4): Return ENOTSUP from listxattr instead of EPERM
FreeBSD does not permits manipulating extended attributes in the system
namespace by unprivileged accounts, even if account has appropriate
privileges to access filesystem object.
In Linux the system namespace is used to preserve posix acls. Some Gnu
coreutils binaries uses posix acls, eg, install, ls, cp.  And fails if
we unexpectedly return EPERM error from xattr system calls.

In the other hands, in Linux read and write access to the system
namespace depend on the policy implemented for each filesystem, so we'll
mimics we're a filesystem that prohibits this for unpriveleged accounts.

30cdbb5833 freebsd32: Remove mac_syscall from the unimpl list
The mac_syscall system call works fine as long as any MAC module
that provides a mpo_syscall method handles compat32 appropriately.

af93fea710 timerfd: Move implementation from linux compat to sys/kern
Move the timerfd impelemntation from linux compat code to sys/kern. Use
it to implement the new system calls for timerfd. Add a hook to kern_tc
to allow timerfd to know when the system time has stepped. Add kqueue
support to timerfd. Adjust a few names to be less Linux centric.

cbb3ec2523 mt76: update driver from upstream
This is a set of updates of the mt76 driver based on wireless-testing

  This adds support for mt7996 as well.

(wt-2023-08-06) 2a220a15be657a24868368892e3e2caba2115283 (after v6.5-rc4).

The current version of LinuxKPI lacks support for "page pool" which
needs enhancing and updating a decade or so old shortcut mapping
struct page directly to struct vm_page.

adff403fe7 LinuxKPI: 802.11: update compat code for updated drivers
Adjust and add structs, fields, functions to make more modern versions
of LinuxKPI based wireless drivers (based on wireless-testing (
wt-2023-06-09, wt-2023-07-24, and later)) compile.

Some of these changes can only be applied once all drivers get
updated to not break the old versions currently in the tree.
Mark those changes with __FOR_LATER_DRV_UPDATE for now and flip the
switch at a later point.
