As Colin Cross ported my x86 change to ARM, he also pointed out that
powerpc is also behind in this fix.

The commit 722b3c74

 "ftrace/graph: Trace function entry before
updating index" fixes an issue with function graph tracing for x86,
where if the called entry function decides not to trace interrupts, it
can fail the check if an interrupt comes in just after the
curr_ret_stack is updated.

The solution is to call the entry function first, then update the
curr_ret_stack if the entry function wants to be traced.

This updates the g5 defconfig to include nouveau instead of nvidiafb
(which works much better nowadays, in fact the latter crashes on modern
distros), and to set CONFIG_VT_HW_CONSOLE_BINDING without which takeover
from the firmware offb by nouveau doesn't work properly (and leads to
unexplained black screens for some users).

The rest is churn of going through defconfig / savedefconfig

It was only used for an assignment in init-mm.c and we

This is likely a left-over from the sun4c removal.
