# On the 'tile' arch, USB OHCI needs the bounce pool since tilegx will often
# have more than 4GB of memory, but we don't currently use the IOTLB to present
# a 32-bit address to OHCI. So we need to use a bounce pool instead.
#
# We also use the bounce pool to provide stable page writes for jbd. jbd
# initiates buffer writeback without locking the page or setting PG_writeback,
# and fixing that behavior (a second time; jbd2 doesn't have this problem) is
# a major rework effort. Instead, use the bounce buffer to snapshot pages
# (until jbd goes away). The only jbd user is ext3.
