16eefbd1ed x86/kconfig: Enable CONFIG_JUMP_LABEL in the defconfigs
Enable CONFIG_JUMP_LABEL in the defconfigs, the feature already deals with
GCC not having the asm-goto feature so will not break the build on
older compilers.

Having it enabled generates a faster kernel at very little extra cost
since we already include all the code patching code by having KPROBES
enabled.

fd930478fb drm/i915: Remove KMS Kconfig option
Since we only support modesetting by default (disabling modesetting on
the command line prevents i915.ko from loading), having a parameter to
disable modesstting by default is superfluous, i.e. saying
CONFIG_DRM_I915_KMS=n is equivalent to CONFIG_DRM_I915=n.

6c6685055a kconfig: add xenconfig defconfig helper
This lets you build a kernel which can support xen dom0
or xen guests on i386, x86-64 and arm64 by just using:

   make xenconfig

You can start from an allnoconfig and then switch to xenconfig.
This also splits out the options which are available currently
to be built with x86 and 'make ARCH=arm64' under a shared config.

Technically xen supports a dom0 kernel and also a guest
kernel configuration but upon review with the xen team
since we don't have many dom0 options its best to just
combine these two into one.

A few generic notes: we enable both of these:

CONFIG_INET=y
CONFIG_BINFMT_ELF=y

although technically not required given you likely will
end up with a pretty useless system otherwise.

A few architectural differences worth noting:

$ make allnoconfig; make xenconfig > /dev/null ; \
	grep XEN .config > 64-bit-config
$ make ARCH=i386 allnoconfig; make ARCH=i386 xenconfig > /dev/null; \
	grep XEN .config > 32-bit-config
$ make ARCH=arm64 allnoconfig; make ARCH=arm64 xenconfig > /dev/null; \
	grep XEN .config > arm64-config

Since the options are already split up with a generic config and
architecture specific configs you anything on the x86 configs
are known to only work right now on x86. For instance arm64 doesn't
support MEMORY_HOTPLUG yet as such although we try to enabe it
generically arm64 doesn't have it yet, so we leave the xen
specific kconfig option XEN_BALLOON_MEMORY_HOTPLUG on x86's config
file to set expecations correctly.

Then on x86 we have differences between i386 and x86-64. The difference
between 64-bit-config and 32-bit-config is you don't get XEN_MCE_LOG as
this is only supported on 64-bit. You also do not get on i386
XEN_BALLOON_MEMORY_HOTPLUG, there does not seem to be any technical
reasons to not allow this but I gave up after a few attempts.

9261dc1de1 x86/build/defconfig: Enable USB_EHCI_TT_NEWSCHED=y
Some Gentoo users are encountering problems because
USB_EHCI_TT_NEWSCHED isn't set in the defconfig (and Gentoo
differs from other distros in not providing a distro .config).
Alan Stern has said there's no reason to not set it, and the
ability to turn it off at all should probably be yanked:

  http://article.gmane.org/gmane.linux.usb.general/119920

This addresses issue:

  https://bugs.gentoo.org/show_bug.cgi?id=533472

(The problem also theoretically affects the sh, arm, mips,
powerpc, and sparc archs, but those would be other patches if
this one that fixes 98% of the problem is accepted).

0da1d4a0b9 x86: Add "make tinyconfig" to configure the tiniest possible kernel
Since commit 5d2acfc7b9 ("kconfig: make
allnoconfig disable options behind EMBEDDED and EXPERT") in 3.15-rc1,
"make allnoconfig" disables every possible config option.

However, a few configuration options (CC_OPTIMIZE_FOR_SIZE,
OPTIMIZE_INLINING) produce a smaller kernel when turned on, and a few
choices exist (compression, highmem, allocator) for which a non-default
option produces a smaller kernel.

Add a "tinyconfig" option, which starts from allnoconfig and then sets
these options to configure the tiniest possible kernel.  This provides a
better baseline for embedded systems or efforts to reduce kernel size.

ffee0de411 x86: Default to ARCH=x86 to avoid overriding CONFIG_64BIT
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.

c206b9dcb1 x86/Kconfig: Turn off DEBUG_NX_TEST module in defconfigs
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.

be2f328d86 x86/Kconfig: Turn off CONFIG_BLK_DEV_RAM
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.

3fe2cb8f9e x86/Kconfig: Switch to ext4 in defconfigs
The current x86 and x86-64 defconfigs do not enable ext4, which
most current distributions default to.  Switch the defconfigs to
ext4, so they will boot on current systems without additional
configuration.

a77aea9201 cgroup: remove the ns_cgroup
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.

cb84b19474 x86, hwmon: Package Level Thermal/Power: pkgtemp hwmon driver
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:

physical id 0: +33.0°C  (high = +79.0°C, crit = +99.0°C)

965c7ecaf2 x86: remove the Voyager 32-bit subarch
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.

   x86: defconfig updates

changed CONFIG_RELOCATABLE from n to y, which may lead to a mismatch
between the vmlinux debug information and the runtime location of the
kernel, even when the bootloader does not relocate the kernel.

Revert the specific change. Works for me with GRUB and qemu.
