These produce frequent data race reports: most of them are due to races on

the same word but accesses to different bits of that word. Re-enable KCSAN

for these when we have more consensus on what to do about them.

KCSAN_SANITIZE_slab_common.o := n KCSAN_SANITIZE_slub.o := n KCSAN_SANITIZE_page_alloc.o := n

But enable explicit instrumentation for memory barriers.

KCSAN_INSTRUMENT_BARRIERS := y

These files are disabled because they produce non-interesting and/or

flaky coverage that is not a function of syscall inputs. E.g. slab is out of

free pages, or a task is migrated between nodes.
