Rename the 'flags' and 'nowait' arguments to 'how'. The other BSDs did the

(maxv)

Modify m_defrag, so that it never frees the first mbuf of the chain. While
here use the given 'flags' argument, and not M_DONTWAIT.

We have a problem with several drivers: they poll an mbuf chain from their
queues and call m_defrag on them, but m_defrag could update the mbuf
pointer, so the mbuf in the queue is no longer valid. It is not easy to
fix each driver, because doing pop+push will reorder the queue, and we
don't really want that to happen.

This problem was independently spotted by me, Kengo, Masanobu, and other
people too it seems (perhaps PR/53218).

Now m_defrag leaves the first mbuf in place, and compresses the chain
only starting from the second mbuf in the chain.

It is important not to compress the first mbuf with hacks, because the
storage of this first mbuf may be shared with other mbufs.

Refactor the traceme2 ATF ptrace(2) tests

These tests call: raise(sig). It's actually important to assert their
behavior for tests that are from different kinds.

The SIGKILL test is work in progress. It can be caught by a debugger on the
FreeBSD kernel, but it's causing a signaled event in a debugger on Linux.

NetBSD is right now in one of the camps, but research whether this is a bug

Don't free and reallocate bus_dmamem when it's not required. Currently,
the watchdog timer is completely broken and never fire (it's from FreeBSD
(pre iflib)). If the problem is fixed and watchdog fired, ixgbe_init() always
calls ixgbe_jcl_reinit() and it causes panic. The reason is that
ixgbe_local_timer1(it includes watchdog function) is softint and
xgbe_jcl_reinit() calls bus_dmamem*() functions. bus_dmamem*() can't be called
from interrupt context.

One of the way to prevent panic is use worqueue for the timer, but it's
not a small change. (I'll do it in future).

Another way is not reallocate dmamem if it's not required. If both the MTU
(rx_mbuf_sz in reality) and the number of RX descriptors are not changed, it's
not required to call bus_dmamem_{unmap,free}(). Even if we use workque, this
change save time of ixgbe_init().

I have a code to fix broken watchdog timer but it sometime causes watchdog
timeout, so I don't commit it yet.

Use spin mutex to fix a panic

The GPIO part of wbsio(4) has a lock to keep the register access
order. In addition to the lock, gpio(4) has a look to prevent
multiple control through gpio_pin_ctl(). Those locks hold at
once when gpio_pin_ctl() is called, and the lock of gpio(4) hold
before that of wbsio(4).

Therefore, the wbsio(4) has to use spin lock if gpio(4) uses
spin lock.

In uses like $(( var )) (un-dollared vars in arithmetic) we allow
leading whitespace in the value of var (because strtoimax() does)

expansion.

Fix that - allow trailing whitespace.  However, continue to insist
upon at least one digit (a non-null var that contains nothing but
whitespace is still an error).

contain "a value that forms a valid integer constant" (with an optional
