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.

- Add locked variants of el_init and el_start.
- Don't initialize the mutex and lock it during el_probe().
- Do initialize the mutex during attach. (el_probe() did destroy the mutex
to cleanup, so this meant the driver was always using a destroyed mutex
when it was running.)
- Setup the interrupt handler after ether_ifattach().
- Fix locking in el_detach() and el_ioctl().
Note: Since I couldn't actually find anyone with this hardware, I'm going
ahead and committing these changes so they won't be lost. I'll remove the
driver in a week (real purpose of the MFC after below) unless someone pipes
up to test this.

effect. since CPU speed is restored by degrees, we cannot use
the facility of saving cpu speed by CPUFREQ_set() effectively.
so, we need to save the value when passive cooling is in effect.

by md(4). Before this change, it was possible to by-pass these flags
by creating memory disks which used a file as a backing store and
writing to the device.
This was discussed by the security team, and although this is problematic,
it was decided that it was not critical as we never guarantee that root will
be restricted.
This change implements the following behavior changes:
-If the user specifies the readonly flag, unset write operations before
opening the file. If the FWRITE mask is unset, the device will be
created with the MD_READONLY mask set. (readonly)
-Add a check in g_md_access which checks to see if the MD_READONLY mask
is set, if so return EROFS
-Do not gracefully downgrade access modes without telling the user. Instead
make the user specify their intentions for the device (assuming the file is
read only). This seems like the more correct way to handle things.
This is a RELENG_6 candidate.

- Add locked variants of my_start() and my_init().
- Assert that the lock is held in several places rather than recursing.
- Overhaul failure case handling in my_attach() so that it will actually
clean up completely in each of the failure cases.
- Setup the interrupt after ether_ifattach() in my_attach().
- Remove unused callout handle from softc.
- Free the metadata for the descriptors my_in detach() (we leaked it
before).
- Fix locking in my_ioctl().
- Remove spls.

- Add a note that additions should be made to if_free_type and not
if_free to help avoid this in the future.
This apparently fixes a use after free in if_bridge and may fix bugs
in other direct if_free_type consumers.

1. Provide larger /, /var, and /tmp partitions (the last increase was
in 2001, and we now have both larger hard drives and more space-hungry
software.)
2. If there is enough space available, allocate extra space to /var
sufficient to store a crash dump.
On systems where harddrivesize > 3 * RAMsize + 10GB, the default sizes
will now be as follows:
swap RAMsize * 2
/ 512 MB
/tmp 512 MB
/var 1024 MB + RAMsize
/usr the rest (8GB or more)
On systems where harddrivesize > RAMsize / 8 + 2 GB, the default sizes
will be in the following ranges, with space allocated proportionally:
swap RAMsize / 8 -- RAMsize * 2
/ 256 MB -- 512 MB
/tmp 128 MB -- 512 MB
/var 128 MB -- 1024 MB
/usr 1536 MB -- 8192 MB
On systems with even less disk space, the existing behaviour is not
changed.
