* We could overrun the eva by as much as L1SEG_SIZE-PAGE_SIZE.
* sva was advanced *twice* for each valid l3 or l2 page, causing it to get out
of sync with the PTE pointers.
remove GENERIC.v6 file (as it is part of GENERIC now).
"faith" interface is commented out by default as it is not really for
general use.
IPsec items are commented out as well, though we can enable "options IPSEC"
without export-related issue ("options IPSEC" will enable authentication
portion only). We may need to think about it again.
if you have problem compiling with INET6 on archs I do not have access to,
please contact me.

keep a "tcdsdev" of the booted tcds device. make sure that the "asc"
is the child of the tcds. this fixes boot device detection on dec
5000/400 (prolly 400-900) machines in the presense of a tcds option
card, which would use the right tcds chip & disk scsiid of the last
attached tcds -- which meant it would choose the wrong disk, or not
find the boot device at all if the corresponding scsiid was unused in
the last attached disk.

fixes PR#8771 by myself.
- Fix a bug where IPL wasn't being lowered to process SIRs, which
effectively caused them to be processed at splserial(), and loop
over the ssir, like we do for astpending.
- Optimize the flow of exception_return().
the page attributes in pmap_enter().
- It's no longer necessary (and hasn't been for a while in this pmap) to
go to splimp() to use the physical->virtual table, so remove all such
uses.
the freebsd-alpha mailing list which basically boiled down to increasing
stack depth due to lowering the IPL before checking for an AST.
This changes AST processing to do basically what the i386 port does (as
described by Charles Hannum):
check_ast:
if (astpending) {
lower IPL
process AST
raise IPL
goto check_ast
}
.
Makes the 64-bit alpha checksum magically contain an embedded 16-bit
Sun (NetBSD/sparc) compatible magic number and checksum. This is the
last piece in the "boot one disk from alpha, sun, and i386" problem.
.
And for those who told me this had been done before, :-P. It turns out,
it was only done in the collective sense by multi-disk distributions.
big-endian. i386, pc532 and vax still include <machine/byte_swap.h>
and define macros for the {n,h}to{h,n}*() functions. mips also
defines some endian-independent assembly-code aliases for unaligned
memory accesses.
that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.
This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).
XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.
* New features:
+ traceback for threads (i.e., pids): db>trace/t 0t<pid>
+ traceback over console restart (halt and SRM continue)
+ print ipl in trapframes when it's known and it changed
+ print emulation and system call entry name (!) if proc is known
--- syscall (240, netbsd.sys_nanosleep) ---
- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
$INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.
this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)
