[PATCH 1/2] powerpc/64: Move HAVE_CONTEXT_TRACKING from pseries to common Kconfig

[PATCH 1/2] powerpc/64: Move HAVE_CONTEXT_TRACKING from pseries to common Kconfig

[Anton Blanchard]

From: Anton Blanchard <anton@samba.org>

We added support for HAVE_CONTEXT_TRACKING, but placed the option inside
PPC_PSERIES.

This has the undesirable effect that NO_HZ_FULL can be enabled on a
kernel with both powernv and pseries support, but cannot on a kernel
with powernv only support.

[PATCH 2/2] powerpc/64: Add BPF_JIT to powernv and pseries defconfigs

[Anton Blanchard]

From: Anton Blanchard <anton@samba.org>

Commit db9112173b18 ("powerpc: Turn on BPF_JIT in ppc64_defconfig")
only added BPF_JIT to the ppc64 defconfig. Add it to our powernv
and pseries defconfigs too.
