e552b66170 Memory controller: resource counters
With fixes from David Rientjes <rientjes@google.com>

Introduce generic structures and routines for resource accounting.

Each resource accounting cgroup is supposed to aggregate it,
cgroup_subsystem_state and its resource-specific members within.

59bd26582d memcgroup: temporarily revert swapoff mod
This patch precisely reverts the "swapoff: scan ptes preemptibly" patch
just presented.  It's a temporary measure to allow existing memory
controller patches to apply without rejects: in due course they should be
rendered down into one sensible patch, and this reversion disappear.

8dc4f3e17d cgroups: move cgroups destroy() callbacks to cgroup_diput()
Move the calls to the cgroup subsystem destroy() methods from
cgroup_rmdir() to cgroup_diput().  This allows control file reads and
writes to access their subsystem state without having to be concerned with
locking against cgroup destruction - the control file dentry will keep the
cgroup and its subsystem state objects alive until the file is closed.

The documentation is updated to reflect the changed semantics of destroy();
additionally the locking comments for destroy() and some other methods were
clarified and decrustified.

deb21db778 VFS: swap do_ioctl and vfs_ioctl names
Rename old vfs_ioctl to do_ioctl, because the comment above it clearly
indicates that it is an internal function not to be exported to modules;
therefore it should have a more traditional do_XXX name.  The new do_ioctl
is exported in fs.h but not to modules.

Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should
preferably be reserved to callable VFS functions which modules may call, as
many other vfs_XXX functions already do.  Export the new vfs_ioctl to GPL
modules so others can use it (including Unionfs and eCryptfs).  Add DocBook
for new vfs_ioctl.

4aa323bd83 DS1WM: decouple host IRQ and INTR active state settings
The DS1WM driver incorrectly infers the IAS bit (1-wire interrupt active
high) from IRQ settings.  There are devices that have IAS=0 but still need
the IRQ to trigger on a rising edge.  With this patch, machines with DS1WM
that need IAS=1 have to set .active_high=1 in the ds1wm_platform_data.

4cbc76eadf power_supply: remove capacity_level from list of sysfs attributes
This commit:

commit 8efe444038
Author: Andres Salomon <dilinger@queued.net>
Date:   Wed Dec 12 14:12:56 2007 -0500

    power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL

Removed CAPACITY_LEVEL from every other code, leaving the array with sysfs
attributes with one more entry than the number of enums in power_supply.h.
This leads to some attributes containing the value of the attribute right
after it.  For example, temp_ambient would have the value of
time_to_empty_now.  In my case, I had time_to_full_avg have the value which
should be in model_name, when the former was usually empty.

The early per-cpu handling needs a slight tweak to work when booting

We got away with this for a long time, but can't any longer as now
even printk() calls functions (cpu_clock() for example) that thus make
early references to per-cpu variables.
