Subject: x86: define ARCH_WANT_FRAME_POINTERS

Commit da4276b8299a6544dc41ac2485d3ffca5811b3fb changed a dependency
for FRAME_POINTER from X86 to ARCH_WANT_FRAME_POINTERS, but didn't
actually define it.

This patch adds the definition for ARCH_WANT_FRAME_POINTERS. Without it,
FRAME_POINTER can't be enabled on x86.

Subject: rcu: remove duplicate CONFIG_RCU_CPU_STALL_DETECTOR

Impact: remove the old CONFIG_RCU_CPU_STALL_DETECTOR

tree_rcu introduce CONFIG_RCU_CPU_STALL_DETECTOR again.

These two are the same exactly except:

 the old one "depends on CLASSIC_RCU"
 the new one "depends on CLASSIC_RCU || TREE_RCU"

This patch remove the old one.
