propagate to interface settings
The description for IPV6_PRIVACY mentions using .../all/use_tempaddr to enable
IPv6 Privacy Extensions, and IP sysctl documentation mentions 'all' as setting
all interface-specific settings. We make sure at least use_tempaddr actually
works as documented.

When headers are converted to userspace headers they may include
relative includes. For example x86 has the following in its
asm/posix_types.h:
# ifdef __i386__
# include "posix_types_32.h"
# else
# include "posix_types_64.h"
# endif
However this is not safe in the face of the gcc option -I- which removes
"the directory the file I am being included from" from the search list.
Convert these references to <dir/...> form avoiding this.

Grub may be able to select a graphics mode and paint a splash screen

Introduce a new VT mode KD_TRANSPARENT which endevours to leave the current
content of the framebuffer untouched. This allows the bootloader to insert
a graphical splash and have the kernel maintain it until the OS splash
can take over. When we finally switch away (either through programs like
plymouth or manually) the content is lost and the VT reverts to text mode.

[apw@canonical.com: This has no upstream traction but is used by powertop,
so its worth carrying.]
PowerTOP would like to be able to show who is keeping the disk
busy by dirtying data. The most logical spot for this is in the vfs
in the mark_inode_dirty() function. Doing this on the block level
is not possible because by the time the IO hits the block layer the
guilty party can no longer be found ("kjournald" and "pdflush" are not
useful answers to "who caused this file to be dirty).
The trace point follows the same logic/style as the block_dump code
and pretty much dumps the same data, just not to dmesg (and thus to
/var/log/messages) but via the trace events streams.
Note: This patch was posted to lkml and might potentially go into 2.6.33 but I
have not seen which maintainer will take it.

Track pages which undergo readahead and for each record which were
actually consumed, via either read or faulted into a map. This allows
userspace readahead applications (such as ureadahead) to track which
pages in core at the end of a boot are actually required and generate an
optimal readahead pack. It also allows pack adjustment and optimisation
in parallel with readahead, allowing the pack to evolve to be accurate
as userspace paths change. The status of the pages are reported back via
the mincore() call using a newly allocated bit.

When a drm driver is initialised we first allocate and initialise the
drm minor numbers including creating the sysfs files, then we trigger
the driver load method. The act of creating the sysfs files triggers the
uevent. This means udev may start programs which open /dev/dri/card0 and
other interfaces, this can occur before the load method has even started
and thus before the driver has fully initialised its data structures.
In the case of plymouthd this leads to it opening and closing (in disgust)
the interface, which in turn leads to a kernel panic as the mutexes are
yet to be initialised.
This patch delays the linking up of the drm devices minor numbers until
the driver is fully initialised. As it is possible for consumers of
these interfaces to reach them before they are fully initialised we
arrange for opens of these devices to return EAGAIN until the device is
fully initialised.

Some init packages such as upstart find having all of the kernel parameters
passed in useful. Currently they have to open up /proc/cmdline and
reparse that to obtain this information. Add a kernel configuration
option to enable passing of all options.
Note, enabling this option will reduce the chances that a fallback from
/sbin/init to /bin/bash or /bin/sh will succeed. Though it should be
noted that there are commonly unknown options present which would already
break this fallback. init=/bin/foo provides explicit control over options
which is unaffected by this change.
