In commit 1aefc75b2449 ("cpufreq: stats: Make the stats code

defconfig still said =m though, which meant we no longer got the
code at all. Switch the defconfig to =y.

In commit d92d9c3a1448 ("drm: hide legacy drivers with CONFIG_DRM_LEGACY")
CONFIG_DRM_RADEON was moved behind CONFIG_DRM_LEGACY meaning it
stopped being enabled by ppc6xx_defconfig. Although no one has
noticed, given this is basically a legacy platform, it seems anyone
who is using it probably still wants this driver. So turn it back on
for now.

In commit e3c4ff6d8c94 ("EDAC: Remove EDAC_MM_EDAC") CONFIG_EDAC grew

In commit a85406afeb3e ("netfilter: conntrack: built-in support for
SCTP"), NF_CT_PROTO_SCTP switched from tristate to bool and became
default y. Similarly in commit 9b91c96c5d1f ("netfilter: conntrack:

tristate to bool and became default y.
We had a few configs which set them to =m, which is no longer valid.
We don't need to change them to =y because both symbols are default y
and are enabled automatically based on the other symbols in the
affected defconfigs.

That in turn causes CONFIG_TREE_RCU_TRACE to be enabled, which selects
CONFIG_DEBUG_FS. The end result is that CONFIG_DEBUG_FS is forced on,
meaning we don't have to enable it in some of our configs.

In commit 73d8ef76006b ("Input: mousedev - stop offering PS/2 to userspace by

Evdev interface has been available for many years and by now everyone
is switched to using it, so let's stop offering /dev/input/mouseN
and /dev/psaux by default.
We had a number of configs which had it enabled, but going by the above
explanation probably don't need it enabled anymore.

Although the MSR tells you what endian you're in it's possible that
isn't the same endian the kernel was built for, and if that happens
you're usually having a very bad day. So print a marker to make
it 100% clear which endian the kernel was built for.

When building a random powerpc kernel I hit this build error:
arch/powerpc/platforms/powernv/opal-imc.c:130:13: error : assignment
discards « const » qualifier from pointer target type
[-Werror=discarded-qualifiers]
l_cpumask = cpumask_of_node(nid);
^
This happens because when CONFIG_NUMA=n cpumask_of_node() returns a
const pointer.
This patch simply adds const to l_cpumask to fix this issue.

The hardware trace macro feature requires access to a chunk of real
memory. This patch provides a debugfs interface to do this. By
writing an integer containing the size of memory to be unplugged into
/sys/kernel/debug/powerpc/memtrace/enable, the code will attempt to
remove that much memory from the end of each NUMA node.
This patch also adds additional debugsfs files for each node that
allows the tracer to interact with the removed memory, as well as
a trace file that allows userspace to read the generated trace.
Note that this patch does not invoke the hardware trace macro, it
only allows memory to be removed during runtime for the trace macro
to utilise.

This helper is used to detect if a uprobe'd function has returned
through a setjmp/longjmp, rather than branching to the LR that was
updated previously by us. This fixes a SIGSEGV that gets generated when
programs use setjmp/longjmp with uretprobes.
We use the arm64 model (arch/arm64/kernel/probes/uprobes.c:
arch_uretprobe_is_alive()) for detecting when stack frames have been
removed from under us.

When called from xive_irq_startup(), the size of the cpumask can be
larger than nr_cpu_ids. This can result in a WARN_ON such as:

This happens because we're being called with our affinity mask set to
irq_default_affinity. That in turn was populated using
cpumask_setall(), which sets NR_CPUs worth of bits, not nr_cpu_ids
worth. Finally cpumask_weight() will return > nr_cpu_ids when passed a
mask which has > nr_cpu_ids bits set.
Fix it by limiting the value returned by cpumask_weight().
