to doubles as bits. fdlibm-1.1 had similar aliasing bugs, but these
were fixed by NetBSD or Cygnus before a modified version of fdlibm was
imported in 1994. TRUNC() is only used by tgamma() and some
implementation-detail functions. The aliasing bugs were detected by
compiling with gcc -O2 but don't seem to have broken tgamma() on i386's
or amd64's. They broke my modified version of tgamma().
Moved the definition of TRUNC() to mathimpl.h so that it can be fixed
in one place, although the general version is even slower than necessary
because it has to operate on pointers to volatiles to handle its arg
sometimes being volatile. Inefficiency of the fdlibm macros slows
down libm generally, and tgamma() is a relatively unimportant part of
libm. The macros act as if on 32-bit words in memory, so they are
hard to optimize to direct actions on 64-bit double registers for
(non-i386) machines where this is possible. The optimization is too
hard for gcc on amd64's, and declaring variables as volatile makes it
impossible.

Remove md_mtx.
Remove GIANT from the mdctl device driver and avoid DROP_GIANT,
PICKUP_GIANT and geom events since we can call into GEOM directly
now.
Pick up Giant around vn_close().
Apply an exclusive sx around mdctls ioctl and preloading to protect
lists etc..
Don't initialize our lock (md_mtx or md_sx) from a
SYSINIT when there is a perfectly good pair of _fini/_init
functions to do it from.
Prune any final fractional sector from the mediasize to
keep GEOM happy.
Cleanups:
Unify MDIOVERSION check in (x)mdctlioctl()
Add pointer to start() routine to softc to eliminate a switch{}
Inline guts of mddetach().
Always pass error pointer to mdnew(), simplify implementation.

could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash. Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.
The testsuite is based on a simple driver program that builds a
request from the arguments passed to it and issues the request to
Geom. The driver emits FAIL with the error string or PASS depending
on whether the request completed with an error or not. A -v option
has been added to the driver and causes the request to be dumped.
The -v option to prove(1) controls the -v option to the driver.
The testsuite itself contains a hash of which the key constitutes
the arguments and the value is the expected result.

o eliminate the ED_NO_MIIBUS option. Now, you need miibus to use ed with
pccard. If you have an old ISA or PCI card w/o a miibus, then you'll still
be able to use the ed driver w/o miibus in the kernel. If you have pccard
you'll need mii now. Most pccards these days have miibus, and many
cards have ISSUES if you don't attach miibus. issues I don't want to
constantly rediagnose.
- Add new media_ioctl, mediachg and tick function pointers. The core
driver will call these if they aren't NULL, or return an error if they
are.
- migrate remaining mii code into if_ed_pccard.
o include some notes from my datasheet fishing. this may allow us to
get media status from some pccards.
o Fix one bug that's common to many drivers. call if_free(ifp) after
we tear down the interrupt. ed_intr() depends on ifp being there and
freeing it while interrupts can still happen is, ummm, bad.
panics, which occur when stale ifnet pointers are left in struct
moptions hung off of inpcbs:
- Add in_ifdetach(), which matches in6_ifdetach(), and allows the
protocol to perform early tear-down on the interface early in
if_detach().
- Annotate that if_detach() needs careful consideration.
- Remove calls to in_pcbpurgeif0() in the handling of SIOCDIFADDR --
this is not the place to detect interface removal! This also
removes what is basically a nasty (and now unnecessary) hack.
- Invoke in_pcbpurgeif0() from in_ifdetach(), in both raw and UDP
IPv4 sockets.
It is now possible to run the msocket_ifnet_remove regression test
using HEAD without panicking.

the switch statement in order to make this driver more like other
Ethernet NIC drivers.
- In gem_attach() call gem_stop() in addition to gem_reset() to make
sure the chip actually is stopped and not just reset.
- In gem_stop() also stop the gem_rint_timeout() callout in case the
driver is compiled with GEM_RINT_TIMEOUT defined.
Merge some locking improvements from hme(4):
- Use callout_init_mtx() to close races between gem_stop() and gem_tick()
as weel as gem_stop() and gem_rint() in case the driver is compiled
with GEM_RINT_TIMEOUT defined.
- Use the driver lock instead of Giant in a bus dma callback.
- Lock the driver lock around mii operations.
- Cleanup locking in gem_ioctl().
- Remove redundant assertions that the driver lock is not held in
gem_attach() and gem_detach() since mtx_lock() will assert that
already since the driver lock is not recursive.
- Add callout_drain()'s to gem_detach() after calling gem_stop() to make
sure that if softclock is running on another CPU and is blocked on our
driver lock, we will wait until it has acquired the lock, seen that it
was cancelled, dropped the lock, and awakened us so that we can safely
destroy the mutex.

For any operations which require namei(9) lookups:

__acl_get_link
__acl_set_file
__acl_set_link
__acl_delete_file
__acl_delete_link
__acl_aclcheck_file
__acl_aclcheck_link
-Set the MPSAFE flag in NDINIT
-Initialize vfslocked variable using the NDHASGIANT macro
For functions which operate on fds, make sure the operations are locked:
__acl_get_fd
__acl_set_fd
__acl_delete_fd
__acl_aclcheck_fd
-Initialize vfslocked using VFS_LOCK_GIANT before we manipulate the vnode
