be spread over several devices, and the phcb is usually the main one.
Add agp_machdep.c file which implements MD agp functions (currently
just agp_flush_cache).
function on all (probed) PCI buses:
int pci_find_device(struct pci_attach_args *pa,
int (*match)(struct pci_attach_args *));
The pci_attach_args structure pointed to by pa is filled in if the
device is found, and 1 is returned. Otherwise 0 is returned.
This function is, unfortunately, needed by the i810 agp code. It's
also of use for LKMs.
Also frob pci_probe_bus to take 2 extra args when used by pci_find_device.
APM_IOC_GETPOWER ioctl read/write. Setting the batteryid in the passed
structure returns the data for just that battery. The old ioctl
remains for binary compatibility but has been renamed.
Itojun already did the hard work -- I just added a couple of lines.

Thorpe as an extension to the bus_space(9) API.
Only the mainbus has a working mmap... iomd, podulebus and isa dont have
one yet. Its trivial to add the iomd and isa's memory part but am a bit
hessistant to add it without knowing its implications by heart.
Podulebus might be implemented in 32 bits EASI but otherwise its not really
transparent since there is AFAIK no function to explicitly read one byte or
so .. or is this implemented in a higher level ?
ARM26 and arch/arm32/dnard (Shark) kernels compile and RiscPC and Shark
kernels are tested and function OK.
Implications of other ARM systems like hpcarm and ebarm are propably
minimal or solved trivially.
need to check for curproc being non-NULL since none of the pmap
interfaces which are legal to use in interrupt handlers use this macro.
- use the hit op when flushing the cache in pmap_kremove().
- avoid trusting the optimizer in pmap_clear_reference().
- fix pmap_clear_modify() to reset the mod-bit emulation so we can
detect further modifications to the page, also flushing the cache
for any mappings which might have dirty lines.
kernel_map. use this instead of the static map entries when allocating
map entries for kernel_map. this greatly reduces the number of static
map entries used and should eliminate the problems with running out.
This also involved updating the in-kernel DES functions to correspond
to the versions in our in-tree OpenSSL, because the des_SPtrans table
has changed; the asm code will not work with the old permutation table!
C and i386 asm code for the DES, 3DES, and Blowfish CBC modes is also
included; it is not currently built as the ESP processing in esp_core.c
splits the CBC operation and the cipher transform apart. Hopefully that
will be fixed as there is a substantial performance improvement to be had
from doing so. It will remain necessary to use the C version of the
Blowfish CBC function on some i386 machines, however, as the asm version
uses bswapl, which ony 486 and later processors have. The DES CBC code
doesn't have this problem.
Finally, change esp_core.c to use the ecb3_encrypt function instead of
calling ecb_encrypt three times; this improves performance a bit, in
particular in the asm case.
