This reverts commit 6442eea937.
The patch breaks smp_ops and needs to be reverted. The solution to
allow modular build of KVM is to export smp_ops instead.

It is not safe to to place struct pernet_operations in a special section.
We need struct pernet_operations to last until we call unregister_pernet_subsys.
Which doesn't happen until module unload.
So marking struct pernet_operations is a disaster for modules in two ways.
- We discard it before we call the exit method it points to.
- Because I keep struct pernet_operations on a linked list discarding
it for compiled in code removes elements in the middle of a linked
list and does horrible things for linked insert.
So this looks safe assuming __exit_refok is not discarded
for modules.

[PATCH] De-constify sched.h
This reverts commit a8972ccf00 ("sched:
constify sched.h")
1) Patch doesn't change any code here, so gcc is already smart enough
to "feel" constness in such simple functions.
2) There is no such thing as const task_struct. Anyone who think
otherwise deserves compiler warning.

The current napi_disable() uses msleep_interruptible() but doesn't
(and can't) exit in case there's a signal, thus ending up doing a
hot spin without a cpu_relax. Use uninterruptible sleep instead.

UDP currently uses skb->dev->ifindex which may provide the wrong
information when the socket bound to a specific interface.
This patch makes inet_iif() accessible to UDP and makes UDP use it.
The scenario we are trying to fix is when a client is running on
the same system and the server and both client and server bind to
a non-loopback device.

Coding style cleanups:
- change __inline__ to inline;
- drop space in "* addr" parameters;
- drop space between func. name and '('

Use duplicated inline functions for test_and_set_bit_lock() on x86
instead of #define macros, thus avoiding a bad example. This allows
kernel-doc to run cleanly instead of terminating with an error:
Error(linux-2.6.24-rc1//include/asm-x86/bitops_32.h:188): cannot understand prototype: 'test_and_set_bit_lock test_and_set_bit '

The __deprecated marker is quite useful in highlighting the remnants of
old APIs that want removing.
However, it is quite normal for one or more years to pass, before the
(usually ancient, bitrotten) code in question is either updated or
deleted.
Thus, like __must_check, add a Kconfig option that permits the silencing
of this compiler warning.
This change mimics the ifdef-ery and Kconfig defaults of MUST_CHECK as
closely as possible.

x86_32 CONFIG_HIGHMEM64G with 5GB RAM hung when booting, after issuing
some "request_module: runaway loop modprobe binfmt-0000" messages in
trying to exec /sbin/init.
The binprm buf doesn't see the right ".ELF" header because sg_phys()
is providing the wrong physical addresses for high pages: a 32-bit
unsigned long is too small in this case, we need to use dma_addr_t.
