Tim Gardner, given the following for Trusty, anything further that would need to be checked into or may the linux (Ubuntu) task be closed out:
grep -r CONFIG_DM_RAID45
ubuntu/Makefile:obj-$(CONFIG_DM_RAID45) += dm-raid4-5/
ubuntu/dm-raid4-5/Makefile:obj-$(CONFIG_DM_RAID45) := dm-raid45.o
debian.master/changelog: * Revert "[Config] Disable CONFIG_DM_RAID45"
debian.master/changelog: * [Config] Disable CONFIG_DM_RAID45
debian.master/changelog: * [Config] disable CONFIG_DM_RAID45 on powerpc
debian.master/config/annotations:CONFIG_DM_RAID45 p policy<(arch i386 amd64 &/ value m) | value n> note<PC BIOS specific> mark<MD>
