CVS commit: src/sys/arch/atari/atari

Module Name:    src
Committed By:   tsutsui
Date:           Sat Jan 20 17:37:15 UTC 2018

Modified Files:
        src/sys/arch/atari/atari: bus.c

Log Message:
Fix I/O access failures for regions allocated by bus_space_map(9) on Milan.

Passing to PMAP_WIRED against I/O spaces seems problematic,
probably after yamt-km branch merge, which was committed
between NetBSD 3.0 and NetBSD 4.0.
(i.e. ISA and PCI devices on Milan didn't work after 4.0 release)

According to pmap(9) man page, the "flags" arg for pmap_enter(9)
doesn't take VM_PROT_READ and VM_PROT_WRITE, but pmap_enter()
implementation in sys/arch/m68k/m68k/pmap_motolora.c historically
checks them.
