Merge the projects/clang-sparc64 branch back to head. This brings in several updates from the llvm and clang trunks to make the sparc64 backend fully functional.
Apart from one patch to sys/sparc64/include/pcpu.h which is still under discussion, this makes it possible to let clang fully build world and kernel for sparc64.
Any assistance with testing this on actual sparc64 hardware is greatly appreciated, as there will unavoidably be bugs left.
Many thanks go to Roman Divacky for his upstream work on getting the sparc64 backend into shape.
MFC after: 1 month

Align the interfaces for the various watchdogs and make the interface behave as expected.
Also: - Return an error if WD_PASSIVE is passed in to the ioctl as only WD_ACTIVE is implemented at the moment. See sys/watchdog.h for an explanation of the difference between WD_ACTIVE and WD_PASSIVE. - Remove the I_HAVE_TOTALLY_LOST_MY_SENSE_OF_HUMOR define. If you've lost your sense of humor, than don't add a define.
Specific changes:
i80321_wdog.c Don't roll your own passive watchdog tickle as this would defeat the purpose of an active (userland) watchdog tickle.
ichwd.c / ipmi.c: WD_ACTIVE means active patting of the watchdog by a userland process, not whether the watchdog is active. See sys/watchdog.h.
kern_clock.c: (software watchdog) Remove a check for WD_ACTIVE as this does not make sense here. This reverts r1.181.

o Sync with the NetBSD mk48txx driver (the result simplyfies some changes 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.

- Some of the upper bits of the time related (seconds, minutes, etc.) registers are control bits or depending on the model contain additional time bits with a different meaning than the lower ones. In order to only read the desired time bits and not change the upper bits on write use appropriate masks in the gettime and settime function respectively. Due to the polarity of the stop oscillator bit and the fact that the century bits aren't used on sparc64 not masking them didn't cause problems so far. - Fix two off-by-one errors in the handling of the day of week. The genclock code represents the dow as 0 - 6 with 0 being Sunday but the mk48txx use 1 - 7 with 1 being Sunday. In the settime function when writing the dow to the clock the range wasn't adjusted accordingly but the clock apparently played along nicely otherwise the second bug in the gettime function which mapped 1 - 7 to 0 - 6 but with 0 meaning Saturday would have been triggered. Fixing these makes the date being stored in the same format Sun/Solaris uses and cures the "Invalid time in real time clock. Check and reset the date immediately!" when the date was set under Solaris prior to booting FreeBSD/sparc64. [1] Looking at other clock drivers/code e.g. FreeBSD/alpha the former "bug", i.e. storing the dow as 0 - 6 even when the clock uses 1 - 7, seems to be common but might be on purpose for compatibility when multi-booting with other OS which do the same. So it might make sense to add a flag to handle the dow off-by-one for use of this driver on platforms other than sparc64. - Check the state of the battery on mk48txx that support this in the attach function. - Add a note that use of the century bit should be implemented but isn't required at the moment because it isn't used on sparc64.
Problem noted by: joerg [1] MT5 candidate.
