mappings before calling the entry point - change text mappings to read
only and only insert those into the iTLB.
While there remove a few magic constants by information queried from
the firmware.
* Allocate commands on-demand.
* Update a bunch of constants and some structures.
* Use __attribute__ ((__packed__)) instead of __packed to be consistent.
* Support more commands for devices that can apparently handle them.
* Support a "new comm. interface" present in more recent Adaptec
firmware. This reduces the amount of PCI bus traffic in handling
commands.
* Support larger commands going to the adapter--if the adapter can
support them.
* Support 64-bit commands for archs where sizeof(bus_addr_t) > 4 and
for adapters that advertise SGMAP64.
* Handle the WINDOW4G option and NO4GB quirk by excluding 2G-4G window
unless we have the WINDOW4G capability without the NO4GB quirk.
* Ask the adapter more about its capabilities and try to use those if
they seem sane.
* Do our bus_dmamap_sync() inside dequeue_fib instead of following,
since we have the information that we need there.
* Provide access functions for some adapters that I haven't seen yet
(MIPS-based "Rocket" adapters). Not yet used.
simplify ci_feature2_flags and use directly CPUID2_FLAGS on
bitmask_snprintf(9).
Now I can see the same CPUID features than on i386:
$ dmesg|grep -E '(cpu0.*features)'
cpu0: features: bffbfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR>
cpu0: features: bffbfbff<PGE,MCA,CMOV,PAT,PSE36,CFLUSH,B20,DS,ACPI,MMX>
cpu0: features: bffbfbff<FXSR,SSE,SSE2,SS,HTT,TM,SBF>
cpu0: features2: 649d<SSE3,MONITOR,DS-CPL,EST,CID,xTPR>
cpu0: features3: bffbfbff<SYSCALL/SYSRET,XD,EM64T>

Ok'ed by Andrew Doran.
To use it on EM64T CPUs supporting the EST CPUID feature. Note that
some CPUs still don't work with this driver, like Xeon or Pentium 4.
Move the p[34]_get_bus_clock functions into its own file,
intel_busclock.c and remove this code from i386/identcpu.c.
Tested on i386 by myself and amd64 by Tonerre.
compat_10_netbsd32_sys_semsys() (where the one parameter is already in
kernel space).
Note that the code in compat_10_netbsd32_sys_semsys() has always been wrong,
since it called compat_14_sys___semctl() - which would read 64bit values!
initialize it explicitly in identifycpu() (before cpu_configure(9))
because after yamt-idlelwp merge savectx() is called before
cpu_configure(9) and it requires fputype initialized properly,
otherwise a kernel fails in savectx() if a machine doesn't have an FPU.
Mostly taken from mvme68k.
Tested on (not yet integrated) mac68k SONIC Ethernet with MI dp83932.c.
XXX: should we also enable _pmap_set_page_cache{able,inhibit}()
XXX: functions in m68k/pmap_motorola.c for BUS_DMA_COHERENT support?
