Hi,
Building 4.9.94 in the same way we have been building previous 4.9 releases yields the following error:
DEBUG: tests/code-reading.c: In function 'read_object_code':
DEBUG: tests/code-reading.c:228:19: error: 'KMOD_DECOMP_LEN' undeclared (first use in this function)

As far as I can see, KMOD_DECOMP_LEN was introduced by 7525a238be8f ("perf tests: Decompress kernel
module before objdump"), but I have zero deep knowledge in this area so I may be very wrong here.
