90acd67a3c Need CACHELINESIZE for libkern memset. 2001-11-29 00:16:35 +00:00

ecb81c3f6d - convert usage of "defopt" to "defflag" where the relevant option does 
not support a value (e.g., it's to be used as "options FOO" instead of
  "options FOO=xxx"). options that take a value were converted to
  defparam recently.
- minor whitespace & formatting cleanups

0fa231134c - replace "defopt" with "defparam" for options which must take a value, 
as config(8) will warn for value-less defparam options

34d4887431 Some #ifdef cleanup for DIAGNOSTIC/DEBUG/PMAPCHECK so that that many of 
the expensive checks are skipped when (!DEBUG&&!PMAPCHECK) and all of the
light-weigth checks are skipped when (!DIAGNOSTIC&&!DEBUG&&!PMAPCHECK).
This bring pmap.o's text down from 21KB (with PMAPCHECK) to 18.5KB (DEBUG)
to 16KB text (!DIAGNOSTIC).

ab93af26ea Fix pte_clear to TLB flush the va, not the tlb adress (which is only valid 
for clearing the ref bit).  pvo_to_pte (if !diagnostic) will return NULL
immediately if PTE_VALID is not set.

15a42388c0 In pmap_enter(), sync the instruction cache if VM_PROT_EXECUTE. Fixes 
problems when executing programs where text is copied to a page without
a dma sync (like NFS data bcopy'd to a buffer cache page).

6d536163de Change defaults for kernel compiles. Default all to USETOOLS?=no and have 
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.

Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.

to do it here in the Makefile.

49c87d1447 /dev/mem was severely broken. If you tried to access outside managed memory, 
it would go into an infinite loop.  Instead, allow such I/O.

Also, implement mmap(2) for /dev/mem.

4c99916337 va_{start,end} audit: 
Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).

Improved by comments from enami and christos -- thanks!

Heimdal/krb4/KAME changes already fed back, rest to follow.

Inspired by, but not not based on, OpenBSD.

1661137341 it's perfectly legal for pmap_extract() on the kernel pmap to not find 
anything mapped there, even though it never used to happen.  with today's
other changes it happens a lot now, so remove the debug check for it.

0e7661f023 Update pmap_update to now take the updated pmap as an argument. 
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.
