2f4347932e Only include <sys/memrange.h> on i386/amd64 as it really isi 
architecture-specific.  This prevents us from trying to establish
write-combining mappings on other architectures, which in turn makes
non-kms pci video drivers work again on those platforms.

94e6ae1917 Fix typo/pasto in previous commit; request write combining mapping when it 
is actually requested and not for every writable mapping.

d324f4a41d Attempt to establish a write combining mapping instead of relying on mttrs. 
Setting the mttrs failson my thinkpad x1 rev 3, making the xorg-video-vesa
driver painfully slow.  This makes the machine somewhat usable.

eb9a95d64d Use PCIOCREADMASK to size the PCI BARs. This makes more parts of libpciaccess 
usable when machdep.allowaperture is zero.

c63c2890f1 calloc the pci_sys struct before probing for PCI. 
As the functions check if the member pointers are NULL but not the
pointer to the struct itself.

Reworked version of a diff from ratchov@ who created it to prevent a
xserver crash on zaurus where there is no PCI.

6dbbb49403 If opening /dev/pciN read-write fails, try opening it read-only. This allows 
X to run with machdep.allowaperture=0 on inteldrm(4) and radeondrm(4).

027633f14a Add support for X server privilege separation to pci_legacy_open_io() 
With privilege separation the X server enables legacy i/o port
access during the early privileged initialization. Other calls
should be no-op.

Makes X server 1.12 happy with privilege separation.

adb2857e13 Fix pci_io_handle allocation routines. 
The previous version of new_io_handle()  would invalidate all previous
allocations when realloc moves the base pointer of the ios array.
Since I cannot figure out where this array is useful, just get rid of
it, providing sound stable memory allocation.

Fixes vgaHWSaveFonts() in 1.12 xserver on OpenBSD, but other
sub-systems relaying on pci_io could be affected too.

4cd1a7a593 When trying to map a piece of device memory with a cacheability attribue 
(e.g.  the graphics aperture on most video cards), don't error if we
failed to set the mtrr but the map succeeded. Instead print a warning (other
osen handle this case similarly).

Libraries shouldn't use fprintf(stderr, ...); but libpciaccess is really
quite poorly designed.

This diff means that mine and drahn's laptops work with xserver 1.5.
