(mostly based on pmax)
- pass symbol info from bootloader to kernel via bootinfo
(currently bootinfo is allocated in the bootloader and
copied by kernel later; maybe we should rethink about this)
- use passed bootinfo to initialize ksyms(4) in kernel
- remove options SYMTAB_SPACE from kernel config files
- bump bootloader version
This allows us to convert aucom to just another com attachment, and cleanup
some code in the com_arbus.c.
Additionally, we use a common com_cleanup routine rather than having a
zillion copies of it in the attachment points.
This has been tested on a number architectures, and it has been shown to get
close to comparable performance when COM_REGMAP is defined, and comparable
when it is not defined.

- always enable options MIPS3_ENABLE_CLOCK_INTR and just clear the compare
register in cpu_intr() to make CLKF_BASE() works
properly
- prepare only possible number of cpu_inttab
- use macro for interrupt priority number passed to arc_set_intr()
to avoid confusion
- merge arc_hardware_intr() into cpu_intr()
- check independent timer interrupt first in cpu_intr()
- tweak MIPS_SR_INT_IE before calling hardclock timer handlers so that
spllowersoftclock(9) will be invoked properly in hardclock(9)
- reenable interrupt for timer in cpu_intr() rather than each timer handlers
okay'ed by soda.
Note the real fix is to make CLKF_BASE() check all independent
interrupt sources including jazz and isa devices.
clear MIPS_SR_INT_IE in struct clockframe status to prevent
unintentional spllowersoftclock(9) in hardclock(9).
This may be required because current CLKF_BASEPRI() implementation
of NetBSD/arc doesn't check ICU_MASK and all ISA devices share
the same MIPS CPU INT2 interrupt.
BTW, has anyone tried IPL_ICU_MASK on any mips ports?
so that PCI devices over ppb(4) work properly on PCI based NEC machines.
Tested on my NEC JC94 (Express5800/230) and 3Com 3C982-TXM,
which has a DEC/Intel 21154 PCI-PCI bridge and two 3C920 Ethernet chips.
ones and those for specific machines of developers. PR 32304.
OK'ed by rpaulo.
N.B. stf is a cloning device, so it still must be enabled by
"ifconfig stf0 create".
- use vmspace rather than proc or lwp where appropriate.
the latter is more natural to specify an address space.
(and less likely to be abused for random purposes.)
- fix a swdmover race.
