Hardware testing

We booted each kernel and ran the following tests:

aarch64: Host 1: ✅ Boot test ✅ xfstests: ext4 ✅ xfstests: xfs ✅ selinux-policy: serge-testsuite ✅ lvm thinp sanity ✅ storage: software RAID testing 🚧 ✅ Storage blktests

  Host 2:

     ⚡ Internal infrastructure issues prevented one or more tests (marked
     with ⚡⚡⚡) from running on this architecture.
     This is not the fault of the kernel that was tested.

     ✅ Boot test
     ✅ Podman system integration test (as root)
     ✅ Podman system integration test (as user)
     ✅ Loopdev Sanity
     ✅ jvm test suite
     ✅ Memory function: memfd_create
     ✅ AMTU (Abstract Machine Test Utility)
     ✅ Ethernet drivers sanity
     ✅ Networking socket: fuzz
     ✅ Networking sctp-auth: sockopts test
     ✅ Networking: igmp conformance test
     ✅ Networking TCP: keepalive test
     ✅ Networking UDP: socket
     ✅ Networking tunnel: gre basic
     ✅ Networking tunnel: vxlan basic
     ✅ audit: audit testsuite test
     ✅ httpd: mod_ssl smoke sanity

     🚧 ⚡⚡⚡ LTP lite

read_all_sys is triggering hard lockups on specific arm64 while reading /sys. LTP doesn't hit it 100%, but a plain "cat" or "hexdump" works reliable for me.

Doesn't seem to be recent, Fedora's 5.0.9-301.fc30.aarch64 hanged too on same file. I sent a description to arm list: https://lore.kernel.org/linux-arm-kernel/1507592549.3785589.1570404050459.Ja...
