Subject: [PATCH 1/3] iommu/io-pgtable-arm: Prepare for modularization
The io-pgtable-arm and io-pgtable-arm-v7s source files will
be compiled as separate modules, along with the io-pgtable
source. Export the symbols for the io-pgtable init function
structures for the io-pgtable module to use.
Signed-off-by: Isaac J. Manjarres <isaacm@...eaurora.org>
