Pull first stage of __cpuinit removal from Paul Gortmaker:
"The two commits here 1) dummy out all the __cpuinit macros so that we
no longer generate such sections, and then 2) remove all the section
processing that we used to do for those sections.
This makes all the __cpuinit and friends no-ops, so that we can remove
the use cases of it at our leisure. Expect stage 2, which does the
tree wide removal sweep at the end of the merge window."

While doing some code inspection, I noticed that the slob constructor
method can be called with a NULL pointer. If memory is tight and slob
fails to allocate with slob_alloc() or slob_new_pages() it still calls
the ctor() method with a NULL pointer. Looking at the first ctor()
method I found, I noticed that it can not handle a NULL pointer (I'm
sure others probably can't either):
static void sighand_ctor(void *data)
{
struct sighand_struct *sighand = data;
spin_lock_init(&sighand->siglock);
init_waitqueue_head(&sighand->signalfd_wqh);
}
The solution is to only call the ctor() method if allocation succeeded.

CPU partial support can introduce level of indeterminism that is not
wanted in certain context (like a realtime kernel). Make it
configurable.

At the moment, kmalloc() isn't even listed in the kernel API
documentation (DocBook/kernel-api.html after running "make htmldocs").
Another issue is that the documentation for kmalloc_node()
refers to kcalloc()'s documentation to describe its 'flags' parameter,
while kcalloc() refered to kmalloc()'s documentation, which doesn't exist!
This patch is a proposed fix for this. It also removes the documentation
for kmalloc() in include/linux/slob_def.h which isn't included to
generate the documentation anyway. This way, kmalloc() is described
in only one place.

Some architectures (e.g. powerpc built with CONFIG_PPC_256K_PAGES=y
CONFIG_FORCE_MAX_ZONEORDER=11) get PAGE_SHIFT + MAX_ORDER > 26.
In 3.10 kernels, CONFIG_LOCKDEP=y with PAGE_SHIFT + MAX_ORDER > 26 makes
init_lock_keys() dereference beyond kmalloc_caches[26].
This leads to an unbootable system (kernel panic at initializing SLAB)
if one of kmalloc_caches[26...PAGE_SHIFT+MAX_ORDER-1] is not NULL.
Fix this by making sure that init_lock_keys() does not dereference beyond
kmalloc_caches[26] arrays.

vhost_net_ubuf_put_and_wait has a confusing name:
it will actually also free it's argument.
Thus since commit 1280c27f8e29acf4af2da914e80ec27c3dbd5c01
"vhost-net: flush outstanding DMAs on memory change"
vhost_net_flush tries to use the argument after passing it
to vhost_net_ubuf_put_and_wait, this results
in use after free.
To fix, don't free the argument in vhost_net_ubuf_put_and_wait,
add an new API for callers that want to free ubufs.

It also fixes a bug where ISCSI_OP_SCSI_TMFUNC type commands

This patch changes iscsit_add_reject() + iscsit_add_reject_from_cmd()
usage to not sleep on iscsi_cmd->reject_comp to address a free-after-use
usage bug in v3.10 with iser-target code.
It saves ->reject_reason for use within iscsit_build_reject() so the
correct value for both transport cases. It also drops the legacy
fail_conn parameter usage throughput iscsi-target code and adds
two iscsit_add_reject_cmd() and iscsit_reject_cmd helper functions,
along with various small cleanups.

* Fix version recognition in elantech_set_properties
The new hardware reports itself as v7 but the packets'
structure is unaltered.
* Fix packet type recognition in elantech_packet_check_v4
The bitmask used for v6 is too wide, only the last three bits of
the third byte in a packet (packet[3] & 0x03) are actually used to
distinguish between packet types.
Starting from v7, additional information (to be interpreted) is
stored in the remaining bits (packets[3] & 0x1c).
In addition, the value stored in (packet[0] & 0x0c) is no longer
a constant but contains additional information yet to be deciphered.
This change should be backwards compatible with v6 hardware.

- precise nanoseconds RTC readout (Xen feature)
- generic support for Xen suspend/resume oddities
- the usual lot of fixes and cleanups all over the place
The parts which touch other areas (ARM/XEN) have been coordinated with
the relevant maintainers. Though this results in an handful of
trivial to solve merge conflicts, which we preferred over nasty cross
tree merge dependencies.
The patches which have been committed in the last few days are bug

Certain older rv770 asics have both a performance and
a 3D performance state rather than just multiple performance
levels in the state power state. The current code would
select the performance state rather than the 3D performance
state when the "performance" profile was selected. This change
switches to the "balanced" profile by default which ends up being
the internal performance profile. When the user selects the
"performance" profile, it selects the internal 3D performance
state so the user can select the higher performance modes.
For most asics this changes nothing. For certain rv770 asics
with static performance and 3D performance states, this allows
you to select between then using by selecting the "balanced"
and "performance" dpm profiles.
