b0c61d654b Fix LOCKDEBUG kernel panic when many(about 200) tunnel interfaces is created. 
The tunnel interfaces are gif(4), l2tp(4), and ipsecif(4). They use mutex
itself in percpu area. When percpu_cpu_enlarge() run, the address of the
mutex in percpu area becomes different from the address which lockdebug
saved. That can cause "already initialized" false detection.

354fb9ed32 Fix a bug introduced in rev1.154 (2009). mcl_cache still has a size of 
MCLBYTES, so the area allocated is still too small.

I think it should have been MEXTMALLOC, and of course I can't test my
change.

2679f01cd0 Hum. This should be M_READONLY, not M_ROMAP. 
M_ROMAP tells us whether the mbuf storage is mapped on a read-only page.
But an mbuf can still be read-only in the sense that the storage is
shared with other mbufs.

a3e322b567 Change MCLGET, so that it calls m_clget instead of doing the work in a 
macro. Macros are inefficient when they contain too many instructions and
are used too often, because of cache coherency (and also register use).

This change saves 32KB of kernel .text.

d1f63c06dc 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.

bb9c38f4bf 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.
