so that special setup functions needed for some CPUs will be run before
some things (like UVM) are inited.
Add vm_page_zero_enable = FALSE to the cyrix 6x86 case, as page zeroing
while idle causes problems.
I-sync in pmap_remove_mapping() if the old mapping had PG_EXEC, and
kick curcpu (IMB) or other CPUs (via an IPI) only if the pmap was
the kernel pmap or active on other CPUs (curcpu is handled in userret()).
- Use lazy I-sync everywhere, (hopefully) eliminating the last of the
I-sync issues for multiprocessor support.
- Eliminate some memory barriers added in a couple of previous revisions,
after some discussion on port-alpha/tech-smp.
Still some lazy I-sync optimization possibilites:
- pmap_changebit() does not need to I-sync when only write-protecting
a page.
- pmap_asn_alloc() may be able to cancel a pending lazy I-sync when a
new ASN is allocated. Need to double check against Green Book or
Brown Book.

* Fixup the indenting in a few places to conform to NetBSD style
(/mnt)/usr/share/zoneinfo in a listbox, and setting (/mnt)/etc/localtime
accordingly.
* Adjust for the needed menuc change un run.c's log_flip() and script_flip()
functions.

* bring closer to KNF
* when selecting a item in a menu, call the opt_action() callback with
a pointer to the struct menudesc, so the callback has a chance to find
out which item was selected. Having a seperate callback for each
item is ok for small menus, but not for ones with many objects.
* Add menu-option MC_NOSHORTCUT to not print letters ("a: ", ...)
in front of list items. Again, this is for menues with lots of entries
as e.g. the upcoming sysinst set_timezone() function composes.
* Fix a long-standing bug WRT pagewise scrolling - the cursor is now
properly placed one page up/down
searchs (amongst others) are case insensitive.
* in interactive mode (-i), when editing entries display supported disk types
and filesystem types when given `?' (when ``[?]'' appears in the prompt
this feature is supported for the question).
* support `m' as a suffix equivalent to `M'
* in interactive mode, be a bit more sensible about handling errors and EOF
* implement dumpnames(), which takes a char ** and size, and displays
as per ls -F (sorted, listed vertically) but indented by one tab
* don't assume d_typename and d_packname are NUL terminated
* fix up some comments and some warning messages (bad cut & pastos :)
* deprecate deffstypename() and getfstypename()
* be consistent when using sizeof()

writes (>4k) that are not aligned to incorrectly write 64bytes
of data every 4k interval. This only occurs on raw devices - typically

onintstack to be real integers. Add ISP_ILOCK/ISP_IUNLOCK macros.
Fix the isp_lock/isp_unlock inlines to stop being so embarrassingly
in error. Why, or why, can't I have mutex_enter/mutex_exit, pretty please?
Clarify some startup SCSI mode settings. Insist that the FC f/w options
*must* have ICBOPT_PDBCHANGE_AE set (wasted a half day on this crock).
Make a specific comment in isp_start that the tags being selected for FC
cards, in lieu of any set by the outer layers, are there for safety's sake.
This removes the change from a previous commit.
For the ISP_TOGGLE_TMODE function, do a complete reset, not just an
isp_init (info from Solaris port). Make some cleanup changes for
code clarity.

more fundamental solution should appear later, when kame side stablizes it.
