in PR port-alpha/36628:
- make jensenio_eisa_maxslots() return 8 (instead of 16) since
EISA config for slot 8-15 on jensen could return invalid values
- pass eisa_chipset_tag_t to eisa_init() and check eisa_maxslots()
on probing EISA config space
- pass M_ZERO to malloc(9) and make sure malloc(9) doesn't fail
- fix typo in a debug printf, add more debug printfs, and
use #ifdef EISA_DEBUG to enable them
- cast uint8_t value to uint32_t before shift more than 8 bits
- check buffer region on reading compressed data from EISA config space
found, rather maintain a global counter for all sensors that are unique,
and use this global to get the correct index in the array.
- Use prop_array_set() rather than prop_array_add() for adding dictionaries
into our global array. Thanks to yamt@.
- Overwrite the sensor index in the first sensor of a device, to avoid
a problem with LKMs where the first sensor gets the index of all edata
structures allocated in kernel.
- Add missing proto for sme_register_sensorname().
All them fix another part of yamt@'s PR.
there are no more events.
- Add sme_event_unregister_all() to remove all events associated with
a device and use it in sysmon_envsys_unregister() to fix a "use-after-free".
- Check return error of sme_sensor_upfoo() in sme_make_dictionary() and
return it rather than 0 all the time.
- Add more KASSERTS.
with new kern/kern_cctr.c in TODO comments
- also replace struct cc_microtime_state member in struct cpu_info
with struct cctr_state defined in <sys/cctr.h>, which is unused yet
in this port
- sme_register_sensorname: there's no need to handle empty list case.
- 'obj' argument in sme_sensor_upstring and similar functions is useless:
removed the obj argument from the functions, it's handled in the function
itself now.
- check for more errors in sme_make_dictionary() and
sysmon_envsys_createplist().
- use todr(9) API with MI mc146818(4) driver and remove homegrown
todr stuff from MD alpha/clock.c and alpha/mcclock.c
- also remove obsolete cc_microtime stuff from MD code
- add ci_pcc_freq member in struct cpu_info for cpu_frequency(), and
calibrate it with mc146818 interval clock in mcclock attachment
- call cc_init() in cpu_initclocks(9) because all alpha cpus have
a pcc counter
Tested on DEC 3000/300 and AlphaPC 164, but not on any SMP machines yet.
timecounter(9) support functions split out from sys/arch/x86/x86/tsc.c.
Written by and ok'ed to commit by kardel@.
Also add <sys/cctr.h>, which is copied from #ifdef __HAVE_TIMECOUNTER
part of <sys/cc_microtime.h> to migrate MI kern_cctr.c per each port.

Fixes MMU fault panic in trap() on sun3x.
This should be pulled up to netbsd-4 too.
