X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d2f15e0979ee;p=openwrt%2Fstaging%2Fblogic.git powerpc/32: always populate page tables for Abatron BDI. When CONFIG_BDI_SWITCH is set, the page tables have to be populated allthough large TLBs are used, because the BDI switch knows nothing about those large TLBs which are handled directly in TLB miss logic.
