Dear Khasim,

I tried to build  kernel on branch lsk/linux-linaro-lsk-android. but the compiler complained the following messages:

16:03:52@~/work/linux-linaro-tracking$ make
  CHK     include/generated/uapi/linux/version.h

   ^
cc1: some warnings being treated as errors
make[1]: *** [arch/arm64/kernel/ptrace.o] Error 1
make: *** [arch/arm64/kernel] Error 2

I thought this branch is not tested on arm64. that's said we use another branch to develop linaro-android for arm64. Am I right?

If I got it could you tell me witch branch should I track for develop android on arm64?

Many thanks.
