-update PIC _after_ the interrupt handler is linked into the chain
This fixes problems with dynamically installed interrupt handlers:
Interrupts were enabled before the handler was installed under some
circumstances (esp. on faster machines), leading to endless interrupt
handling.
CardBus bus stub, YENTA PCI-CardBus bridge (cbb), 3Com 3C575TX driver
(ex) and Intel fxp driver.
TODO:
o Conform to the KNF more strictly.
o Be unified with pcmcia code as much as possible.
o Add more drivers for CardBus card, such as APA-1480 or USB card.

(The latter 2 follow PR port-i386/8196 by Stephan Thesing.)
power status on the console (if apmd is absent).
Some systems generate APM_POWER_CHANGE events too frequently (more then
once per minute), and printing the status makes single user operations
rather difficult.
to be the logarithm to base 2 of the alignment, in an ELF environment n is
the actual alignment boundary; thus, adjust the directives accordingly.
Albeit the wonderful i386 architecture doesn't mind the smaller alignment in
an obvious way, it is likely to have resulted in some performance penalty
during the a.out->ELF transition.
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.
via interrupts:
(1) pmap_map_ptes() and pmap_unmap_ptes() don't need to do anything to
map the kernel's pmap, since all pmaps contain the kernel's PTPs.
this fixes interrupt-context calls to pmap_extract().
(2) pmap_kenter_*() and pmap_kremove() no longer adjust the kernel pmap's
resident and wired counters.
added APM event type and print out some more info if APMDEBUG
-separate segment lenghts of 16-bit and 32-bit code cleanly

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.
free a PV page if the PV entry was associated with the kernel pmap,
since the kernel pmap is locked, and freeing the page will execute
a code path which will attempt to lock it again, resulting in deadlock.
No real loss, since the next time a PV entry is freed, the page will
be freed, too.
by default. The X11 distribution included in our last release already
supports it and the wsmouse protocol can be used for any of the above
and for USB mice.
- 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. :)
- remove "need-flag" for mac68k esp driver, as it is not used in anywhere
and conflicts with IPsec ESP header.
This should be the only MD change in IPv6 support, except kernel config file.
Very sorry if you have any compilation problem with it (I believe it is okay).
If your favorite arch is not included in here, please add a
call to ip6intr() from softintr handle.
allocation strategy no longer works at all. Move pmap.new.* to pmap.*.
To read the revision history of PMAP_NEW up until this merge, use cvs
rlog of the old pmap.new.* files.
has PAGEABLE and INTRSAFE flags. PAGEABLE now really means "pageable",
not "allocate vm_map_entry's from non-static pool", so update all map
creations to reflect that. INTRSAFE maps are maps that are used in
interrupt context (e.g. kmem_map, mb_map), and thus use the static
map entry pool (XXX as does kernel_map, for now). This will eventually
change now these maps are locked, as well.
managed pages, into KVA space. Since the pages are managed, we should
use pmap_enter(), not pmap_kenter_pa().
Also, when entering the mappings, enter with an access_type of
VM_PROT_READ | VM_PROT_WRITE. We do this for a couple of reasons:
(1) On systems that have H/W mod/ref attributes, the hardware
may not be able to track mod/ref done by a bus master.
(2) On systems that have to do mod/ref emulation, this prevents
a mod/ref page fault from potentially happening while in an
interrupt context, which can be problematic.
This latter change is fairly important if we ever want to be able to
transfer DMA-safe memory pages to anonymous memory objects; we will need
to know that the pages are modified, or else data could be lost!
Note that while the pages are unowned (i.e. "just DMA-safe memory pages"),
they won't consume any swap resources, as the mappings are wired, and
the pages aren't on the active or inactive queues.
end of the mappable kernel virtual address space. Previously, it would
get called more often than necessary, because the caller only new what
was requested.
Also, export uvm_maxkaddr so that uvm_pageboot_alloc() can grow the
kernel pmap if necessary, as well. Note that pmap_growkernel() must
now be able to handle being called before pmap_init().
the child inherits the stack pointer from the parent (traditional
behavior). Like the signal stack, the stack area is secified as
a low address and a size; machine-dependent code accounts for stack
direction.
This is required for clone(2).
which set the LDT and share VM space (e.g. new versions of WINE) expect
the LDT to be logically coupled to the address space. Use the new pmap_fork()
interface to copy non-shared user-set LDTs when the address space is forked.
older CHS interface. This works around stupid BIOSs who report that
int13 extensions are present and functional, but fail when you actually
use them. Like Adaptec SCSI BIOSs.
