I have in mind for the genclock interface):
- Recognize the MK48T18 as well (differs from the MK48T08 only in
packaging options and voltages).
- Allow MD code to provide functions for reading/writing NVRAM/RTC
locations.
If passed NULL, the old behaviour using bus_space_{read,write}_1() is
used. Otherwise, all access to the chip goes via the MD functions.
This is necessary for mvmeppc boards where the mk48txx NVRAM/RTC is
not directly addressable.
- Cleanup MI mk48txx(4) todclock driver:
- Prepare mk48txxvar.h and leave only register definitions in
mk48txxreg.h.
- Define struct mk48txx_softc as usual devices and allocate necessary
members in it.
- Change mk48txx_attach() to only take a device_t.
o While converting the sparc64 eeprom driver to the above changes:
- Remove some dead code and stale comments.
- Use the NVRAM size provided by the mk48txx driver instead of hardcoding
it as suggested by a comment.
- Add a comment about why it doesn't make much sense to read the hostid
directly from the NVRAM except for displaying it when attaching.
- Don't print the hostid if it reads all zero because it's stored
elsewhere.
hence bump it to 6.
Note that the last commit message was not quite accurate. While the
assumption exists in the code, it's not possible to have an
uninitialized p there because if lflag is set when username is NULL
then execution would be terminated earlier.
Don't grab Giant in the upper syscall/wrapper code
NET_LOCK_GIANT in the socket code (sockets/fifos).
mtx_lock(&Giant) in the vnode code.
mtx_lock(&Giant) in the opencrypto code. (This may actually not be
needed, but better safe than sorry).
Devfs grabs Giant if the driver is marked as needing Giant.

FILEDESC_LOCK_FAST will just grab the interlocking mutex and hold
it. This should be used for simple modifications of a field.
FILEDESC_LOCK holds a (homegrown) sleepable lock which should be used
where sleeping is required.
The homegrown lock will probably be replaced with a generic type of lock
once we have found out how that should look.

- Allow the upload directory to be optional. If the upload directory
field is cleared to the empty string then no directory will be created.
- Don't create a bin/ subdirectory in ftp's home dir containing ls(1) and
date(1) as ftpd(8) no longer requires it.
- Create a pwd.db file in etc/ instead of a passwd file.
- Ignore NIS compat entries in /etc/group and /etc/master.passwd when
building the anonymous files.

after boot so that PCI is initialized and we can probe for the problem
chipsets. Note that while probed but unusable states are disabled, they
aren't freed yet. In the future, it may make sense to detach them.

a storm is detected, enter "storming" mode which throttles the interrupt
source such that the handlers are run once every clock tick. Previously
we allowed a full set of storm_threshold interations through the handler
before going back to sleep. Also, this currently will intentionally exit
storming mode once a second to see if the storm has passed.

backed out commits were trying to address: when cancelling the timeout
callout, also cancel the abort_task event, since it is possible that
the timeout has already fired and set up an abort_task.
