Hi Alex,
Please consider following linaro-android pull request for "linux-linaro-lsk-v4.4-android" LSK branch.
KernelCI link is down for linaro-android trees and didn't do much of local build testing either. Shamelessly relying on KernelCI build bot results for linux-linaro-lsk-v4.4-android tree for any breakage reporting.
Boot tested on Qemu(vexpress defconfig + android config fragments) + Android M userspace.
Regards, Amit Pundir
