Compiles on x86.
It breaks make in tools/testing/selftests/x86:

The generic implementation no longer builds 32-bit binaries. Is this
the intent?
It's possible to build 32-bit binaries with “make CC='gcc -m32'”, so
perhaps this is good enough?
But with that, I get a warning:
protection_keys.c: In function ‘dump_mem’:
protection_keys.c:172:3: warning: format ‘%lx’ expects argument of type
‘long unsigned int’, but argument 4 has type ‘uint64_t’ [-Wformat=]
dprintf1("dump[%03d][@%p]: %016lx\n", i, ptr, *ptr);

I suppose you could use %016llx and add a cast to unsigned long long to
fix this.
Anyway, both the 32-bit and 64-bit tests fail here:
assert() at protection_keys.c::943 test_nr: 12 iteration: 1
running abort_hooks()...
I've yet checked what causes this. It's with the kernel headers from
4.17, but with other userspace headers based on glibc 2.17. I hope to
look into this some more before the weekend, but I eventually have to
return the test machine to the pool.
Thanks,
