setting vnode sizes, is handled elsewhere: file system vnode creation
or spec_open() for regular files or block special files, respectively.
Add a call to VOP_MMAP() to the pagedvn exec path, since the vnode
is being memory mapped.

following test cases were fixed if a driver tries to register a driver
with sysmon_envsys_register() and the following items appear:
- Sensor with empty description.
- Sensor with state that doesn't match any of ENVSYS_SFOO.
- Sensor with units type that doesn't match any of ENVSYS_FOO.
it has supplied us). If we fault pages which are at offset >= server
size, but less than the in-kernel vnode size, inform the file server
of the latest developments in file size before issueing the fault.
The avoids confusion with files which are not written start to finish.

- There must be three mandatory objects in a sensor to be valid and be
enabled on its dictionary: units, state and desc. If any of these
objects fails for some reason, its dictionary won't created in the
array and sensor will be marked with ENVSYS_FNOTVALID in edata->flags.
That means there won't never be a partial dictionary.
- Mark all invalid sensors and sensors with duplicate description with
ENVSYS_FNOTVALID and remove ENVSYS_FDUPDESC. The former is the generic
way to say that a sensor does not obey the rules and must be not
created.
- sysmon_envsys_createplist: if the array does not contain any object,
release the array and return the error.
And with all that stuff I can go to holidays and be happy.
instead of the result from getcwd(). The works around locking
panics caused by namei calling VOP_READLINK while holding on to a
directory lock and getcwd() trying to acquire that lock. The real
fix would be to get rid of getcwd() calls within VOPs (not locking
safe), but that's not a viable option in the netbsd-4 timeframe.
Suggestion for workaround from David Holland.
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().
