[PATCH 1/2] powerpc/powernv: Add XHCI and USB storage to defconfig

[Michael Neuling]

These are common on bare metal machines, so put them in the defconfig.

This adds 216KB to the vmlinux size

[PATCH 2/2] powerpc/powernv: Add more BPF in defconfig

[Michael Neuling]

This enables BCC (https://github.com/iovisor/bcc) on powernv.

This adds 225KB to the vmlinux size.

I'm inclined to make these =m.

I assume that would still work for bcc?

Yes, that should work too.
As an aside, I had sent a patch to enable BPF_SYSCALL across powernv, 
pseries and ppc64 defconfigs:
https://patchwork.ozlabs.org/patch/721997/

It would be good to have the network related BPF configs enabled across 
all three.

Thanks. That's better.

I'll mush the patches all together and turn them all on across
pseries/ppc64/powernv.

Here's a version that does that. I have merged all the patches
(including UPROBE_EVENT since that is very useful with bcc anyway). I
have also added CGROUP_BPF to get namespace coverage.

Thanks,

powerpc: include bpf/bcc related config options in defconfigs

Specifically:
- CONFIG_BPF_SYSCALL
- CONFIG_NET_SCHED
- CONFIG_NET_CLS_BPF
- CONFIG_NET_CLS_ACT
- CONFIG_NET_ACT_BPF
- CONFIG_CGROUP_BPF
- CONFIG_UPROBE_EVENT

... in pseries, ppc64 and powernv defconfigs.
