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.

- 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().

This apparently fixes a use after free in if_bridge and may fix bugs

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.

which serial device to use in that case respectively to not rely on
the OFW names of the input/output and stdin/stdout devices. Instead
check whether input and output refers to the same device and is of
type serial (uart(4) was already doing this) and for the fallback
to a serial console in case a keyboard is the selected input device
but unplugged do the same for stdin and stdout in case the input
device is nonexistent (PS/2 and USB keyboards) or has a 'keyboard'
property (RS232 keyboards). Additionally also check whether the OFW
did a fallback to a serial console in the same way in case the
output device is nonexistent. While at it save on some variables
and for sys/boot/sparc64/loader/metadata.c move the code in question
to a new function md_bootserial() so it can be kept in sync with
uart_cpu_getdev_console() more easily.
This fixes selecting a serial console and the appropriate device
when using a device path for the 'input-device' and 'output-device'
OFW environment variables instead of an alias for the serial device
to use or when using a screen alias that additionally denotes a
video mode (like e.g. 'screen:r1024x768x60') but no keyboard is
plugged in (amongst others). It also makes the code select a serial
console in case the OFW did the same due to a misconfiguration like
both 'input-device' and 'output-device' set to 'keyboard' or to a
nonexisting device (whether the OFW does a fallback to a serial
console in case of a misconfiguration or one ends up with just no
console at all highly depends on the OBP version however).
- Reduce the size of buffers that only ever need to hold the string
'serial' accordingly. Double the size of buffers that may need to
hold a device path as e.g. '/pci@8,700000/ebus@5/serial@1,400000:a'
exceeds 32 chars.
- Remove the package handle of the '/options' node from the argument
list of uart_cpu_getdev_dbgport() as it's unused there and future
use is also unlikely.
