This Kconfig symbol serves no purpose and its help text is now

again in the future it can be readded in a commit that adds code that

The defconfig kernel can not run under neither fedora16 x86_64 laptop
nor fedora17 x86_64 pc. After enable DEVTMPFS* in x86_64_defconfig, it
will be OK.
DEVTMPFS* is only related with software, so for i386_defconfig may also
need them (at least, it has no negative effect for defconfig).

It is easy to waste a bunch of time when one takes a 32-bit .config
from a test machine and try to build it on a faster 64-bit system, and
its existing setting of CONFIG_64BIT=n gets *changed* to match the
build host. Similarly, if one has an existing build tree it is easy
to trash an entire build tree that way.
This is because the default setting for $ARCH when discovered from
'uname' is one of the legacy pre-x86-merge values (i386 or x86_64),
which effectively force the setting of CONFIG_64BIT to match. We should
default to ARCH=x86 instead, finally completing the merge that we
started so long ago.
This patch preserves the behaviour of the legacy ARCH settings for commands
such as:
make ARCH=x86_64 randconfig
make ARCH=i386 randconfig
... since making the value of CONFIG_64BIT actually random in that situation
is not desirable.
In time, perhaps we can retire this legacy use of the old ARCH= values.
We already have a way to override values for *any* config option, using
$KCONFIG_ALLCONFIG, so it could be argued that we don't necessarily need
to keep ARCH={i386,x86_64} around as a special case just for overriding
CONFIG_64BIT.
We'd probably at least want to add a way to override config options from
the command line ('make CONFIG_FOO=y oldconfig') before we talk about doing
that though.

The x86 defconfigs include exactly one module: test_nx.ko, a
special-purpose module which just exists to do evil things like
executing code off the stack to see if the kernel has enabled NX
support. Anyone who actually uses that module can easily enable
it themselves, but the vast majority of kernel builds don't need
it; disable it by default.

The vast majority of systems either use initramfs or mount a
root filesystem directly from the kernel. Distros have
defaulted to initramfs for years. Only highly specialized
systems would use an actual filesystem-image initrd at this
point, and such systems don't rely on defconfig anyway. Drop
initrd support (and specifically RAM block device support) from
the defconfigs.

The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and
leads to some problems:
* cgroup creation is out-of-control
* cgroup name can conflict when pids are looping
* it is not possible to have a single process handling a lot of
namespaces without falling in a exponential creation time
* we may want to create a namespace without creating a cgroup
The ns_cgroup was replaced by a compatibility flag 'clone_children',
where a newly created cgroup will copy the parent cgroup values.
The userspace has to manually create a cgroup and add a task to
the 'tasks' file.
This patch removes the ns_cgroup as suggested in the following thread:
https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html
The 'cgroup_clone' function is removed because it is no longer used.
This is a userspace-visible change. Commit 45531757b4 ("cgroup: notify
ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a
printk warning users that the feature is planned for removal. Since that
time we have heard from XXX users who were affected by this.

This patch adds a hwmon driver for package level thermal control. The driver
dumps package level thermal information through sysfs interface so that upper
level application (e.g. lm_sensor) can retrive the information.
Instead of having the package level hwmon code in coretemp, I write a seperate
driver pkgtemp because:
First, package level thermal sensors include not only sensors for each core,
but also sensors for uncore, memory controller or other components in the
package. Logically it will be clear to have a seperate hwmon driver for package
level hwmon to monitor wider range of sensors in a package. Merging package
thermal driver into core thermal driver doesn't make sense and may mislead.
Secondly, merging the two drivers together may cause coding mess. It's easier
to include various package level sensors info if more sensor information is
implemented. Coretemp code needs to consider a lot of legacy machine cases.
Pkgtemp code only considers platform starting from Sandy Bridge.
On a 1Sx4Cx2T Sandy Bridge platform, lm-sensors dumps the pkgtemp and coretemp:
pkgtemp-isa-0000
Adapter: ISA adapter
physical id 0: +33.0°C (high = +79.0°C, crit = +99.0°C)

Impact: remove unused/broken code
The Voyager subarch last built successfully on the v2.6.26 kernel
and has been stale since then and does not build on the v2.6.27,
v2.6.28 and v2.6.29-rc5 kernels.
No actual users beyond the maintainer reported this breakage.
Patches were sent and most of the fixes were accepted but the
discussion around how to do a few remaining issues cleanly
fizzled out with no resolution and the code remained broken.
In the v2.6.30 x86 tree development cycle 32-bit subarch support
has been reworked and removed - and the Voyager code, beyond the
build problems already known, needs serious and significant
changes and probably a rewrite to support it.
CONFIG_X86_VOYAGER has been marked BROKEN then. The maintainer has
been notified but no patches have been sent so far to fix it.
While all other subarchs have been converted to the new scheme,
voyager is still broken. We'd prefer to receive patches which
clean up the current situation in a constructive way, but even in
case of removal there is no obstacle to add that support back
after the issues have been sorted out in a mutually acceptable
fashion.
So remove this inactive code for now.

Additional updates to the x86 defconfigs. The goals are, as before:
- Make them usable to testers, more so than distributors or end users,
both of which are likely to have their own config already.
- Keep 32 and 64 bits as similar as is practical.
Changes:
- Use a more generic CPU type (ppro and generic, respectively).
- Bump number of CPUs to 64 (few if any NR_CPUS arrays left).
- Enable PAT.
- Enable OPTIMIZE_INLINE.
- Enable microcode update support.
- Build SMT scheduler support (in addition to MC).
