Although this particular commit will not be at fault, it is the option that 
enables the feature which is the earliest I can bisect the fault to. There are 
3 files in linux that assert fail on the Implement the 'patchable-function 
attribute'. The files in question are kasan/quarantine.c, mm/slab_common.c and 
mm/slub.c .

I reproduced with

  make CC=/path/to/clang/install/clang ARCH=arm64 
CROSS_COMPILE=aarch64-linux-gnu- HOSTGCC=gcc allmodconfig

You can get the log files for the build, which is from clang-10
https://git.linaro.org/toolchain/ci/base-artifacts.git/log/?h=linaro-local/ci/tcwg_kernel/llvm-release-aarch64-mainline-allmodconfig
 (4: update: llvm-linux: 19676)

If the patchable functions is intended for clang-10 we'll need to make sure any 
fix is merged to clang-10.
