These were sourced from the MX25L128 datasheet and match up
with what is used in Linux mtd/devices/m25p80.c .

6ec1ef63d1 Add a call to nfscl_mustflush() in nfs_close() of the experimental
NFSv4 client, so that attributes are not acquired from the server
when a delegation for the file is held. This can reduce the number
of Getattr Ops significantly.

1de98e0687 In keeping with the Age-of-the-fruitbat theme, scale up hirunningspace on

This is a somewhat conservative version of the patch - more fine tuning may be

79848522b5 - Move common code from the hook functions that fills in a packet node struct to
a separate inline function. This further reduces duplicate code that didn't
  have a good reason to stay as it was.

- Reorder the malloc of a pkt_node struct in the hook functions such that it
  only occurs if we managed to find a usable tcpcb associated with the packet.

- Make the inp_locally_locked variable's type consistent with the prototype of
  siftr_siftdata().

060d7431b5 Add hints for i8254 timer on i386 and amd64. Some people report about
systems with PnP/ACPI not reporting i8254 timer. In some cases it can be
fatal, as i8254 can be the only available time counter hardware. From other
side we are now heavily depend on i8254 timer and till the last time it's
init/usage was completely hardcoded. So this change just restores previous
behavior in more regular fashion.

2cf552b115 Patch the experimental NFSv4 server so that it acquires a reference
count on nfsv4rootfs_lock when dumping state, since these functions
are not called by nfsd threads. Without this reference count, it
is possible for an nfsd thread to acquire an exclusive lock on
nfsv4rootfs_lock while the dump is in progress and then change the
lists, potentially causing a crash.

61e1c19319 Revert the previous commit. The race is not applicable to the lockmgr
implementation in 8.0 and later as its flags field does not hold dynamic
state such as waiters flags, but is only modified in lockinit() aside
from VN_LOCK_*().

dbfcf8cfea When the MNTK_EXTENDED_SHARED mount option was added, some filesystems were
changed to defer the setting of VN_LOCK_ASHARE() (which clears LK_NOSHARE
in the vnode lock's flags) until after they had determined if the vnode was
a FIFO.  This occurs after the vnode has been inserted a VFS hash or some
similar table, so it is possible for another thread to find this vnode via
vget() on an i-node number and block on the vnode lock.  If the lockmgr
interlock (vnode interlock for vnode locks) is not held when clearing the
LK_NOSHARE flag, then the lk_flags field can be clobbered.  As a result
the thread blocked on the vnode lock may never get woken up.  Fix this by
holding the vnode interlock while modifying the lock flags in this case.

f50baba14b Simple compatibility hacks for building on older systems where
MACHINE_CPUARCH isn't defined.  I believe that this will cover all
options.

I didn't define it in kern.mk because $M is set to MACHINE_CPUARCH and
then is expanded for the genassym.o rule in kern.post.mk and kern.mk
is included after this, so the expansion isn't quite right.  I think
this is a bug in make, but don't have the time to track it to ground
(and even if I did, fixing it would require a MFC of the change to the
very old systems we're targetting with this fix).
