XXX This is a stopgap fix which can be pulled up to 1.4.x. It only replaces
the arbitrary 16M boundary by an arbitrary 128M boundary. A clean solution
would need changes to the mi loadfile.c parts.
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.

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.
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.
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.
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.
