The intent is to remove all direct zone_mbuf consumers so that ctor/dtor
from that zone can be reimplemented as wrappers around uma, avoiding an
indirect function call.

Instead of having multiple kyua libraries, just include the files as part
of usr.bin/kyua. Previously, we would build each kyua source up to four
times: once as a .o file and once as a .pieo. Additionally, the kyua
libraries might be built again for compat32. As all the kyua libraries
amount to 102 C++ sources the build time is significant (especially when
using an assertions enabled compiler). This change ensures that we build
306 fewer .cpp source files as part of buildworld.

Subtract one SGE for the case of misaligned address. Also take into
account maximum number of sectors reported by firmware, that gives
nicer 256KB limit instead of 276KB calculated from the SGE limit.
While there, remove number of I/O size checks, duplicating what is
already checked by CAM and busdma(9).

libpfctl supports creating rules, but not (yet) adding addresses to a

phandle_t is a uint32_t type, <= 0 comparison doesn't work with it as intended.
This caused the ofw_pci code to attach to PCI bus on ACPI based systems.

Currently all PCIE windows point to bus address 0x0, which does not match
the values obtained from hardware during EA.
Replace those values with CPU addresses, since in reality we
have a 1:1 mapping between the two.
This patch is queued for Linux v5.14 in linux-next tree:
6bee93d93111 "arm64: dts: fsl-ls1028a: Correct ECAM PCIE window ranges"
The r intc interrupt controller seems to do a lot of things :
- It can handle the NMI interrupt
- It have local interrupts for some device that also can be muxed with GIC
- It can serve as an forwarder for the GIC
It's mostly used for deepsleep/wakeup if I understood correctly and we do not
support this on arm64.
For now just forward everything to the GIC so interrupts works again for device
which now have this interrupts controller set since dts v5.12

This introduces a new, per-process flag, "NO_NEW_PRIVS", which
is inherited, preserved on exec, and cannot be cleared. The flag,
when set, makes subsequent execs ignore any SUID and SGID bits,
instead executing those binaries as if they not set.
The main purpose of the flag is implementation of Linux
PROC_SET_NO_NEW_PRIVS prctl(2), and possibly also unpriviledged
chroot.

When the setting of kern.ipc.maxsockbuf is less than what is
desired for I/O based on vfs.maxbcachebuf and vfs.nfs.bufpackets,
a console message of "Consider increasing kern.ipc.maxsockbuf".
is printed.
This patch modifies the message to provide a suggested value
for kern.ipc.maxsockbuf.
Note that the setting is only needed when the NFS rsize/wsize
is set to vfs.maxbcachebuf.
While here, make nfs_bufpackets global, so that it can be used
by a future patch that adds a sysctl to set the NFS server's
maximum I/O size. Also, remove "sizeof(u_int32_t)" from the maximum
packet length, since NFS_MAXXDR is already an "overestimate"
of the actual length.

Similarly to what's been done on arm64 with commit
712c060c94, when executing a binary, if the
entry point is a thumb symbol, then make sure we set the PSL_T flag, otherwise
the CPU will interpret it in ARM mode, and that will likely leads to an
undefined instruction.

This allows supported libpmc to query/select from the pmu-events table,
which may have a more complete set of events than what we define
manually. A future update to these definitions should greatly improve
this support. The alias table is empty for now, until this future import
is complete.
