Linux Kernel 3.10.2 compiles and runs (mods done; .rej cleaned up)

Applied:
/LineageOS/android/kernel/sony/msm8994$ patch -p1 -R <
/home/dj/Downloads/linuxkernelpatches/patch-3.10.2-3

1) arch/arm64/mm/fault.c - #defines adapted because those from patch
missing:
ESR_WRITE -> ESR_EL1_WRITE
ESR_CM -> ESR_EL1_CM

2) not reverted since functions nowhere defined:
