I'm trying to compile this project from github but I am running into the following error:
make -C /lib/modules/5.15.0-53-generic/build M=/home/jr/Documents/ProtoVirt modules EXTRA_CFLAGS="-g -DDEBUG"
make[1]: Entering directory '/usr/src/linux-headers-5.15.0-53-generic'

The command I'm running is make. Can anyone explain to me what I'm doing wrong?
The _ASM_EXTABLE_HANDLE macro is replaced by _ASM_EXTABLE_TYPE in the newest kernel versions.
