Modified Files:
        src/sys/arch/evbsh3/evbsh3 [netbsd-6]: bus_dma.c

Log Message:
Pull up following revision(s) (requested by nonaka in ticket #1237):
        sys/arch/evbsh3/evbsh3/bus_dma.c: revision 1.4
Sync with sys/arch/landisk/landisk/bus_dma.c rev.1.15.
Don't call sh_dcache_inv_range() on BUS_DMASYNC_POSTREAD ops
as other mips and arm ports.
All cached data is cared on BUS_DMASYNC_PREREAD and
invalidating cache without writeback could cause unexpected
data loss if specified sync region is not cacheline aligned.
This may fix "ffs_alloccg: map corrupted" panic on acardide IDE disks,
which didn't happen on USB HDD.
