ceff8d859c Revert "i386: export i386 smp_call_function_mask() to modules"
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.

460cd0589d mmc_spi: Fix mmc-over-spi regression
Patch 49dce689ad changed the sysfs data
structures for SPI in a way which broke the MMC-over-SPI host driver.

This patch fixes that regression by changing the scheme used to keep
from knowingly trying to use a shared bus segment, and updates the
adjacent comments slightly to better explain the issue.

ceaa79c434 [NETNS]: Fix get_net_ns_by_pid
The pid namespace patches changed the semantics of
find_task_by_pid without breaking the compile resulting
in get_net_ns_by_pid doing the wrong thing.

So switch to using the intended find_task_by_vpid.

Combined with Denis' earlier patch to make netlink traffic
fully synchronous the inadvertent race I introduced with
accessing current is actually removed.

2b008b0a8e [NET]: Marking struct pernet_operations __net_initdata was inappropriate
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.

e6e1ace990 x86 setup: sizeof() is unsigned, unbreak comparisons
We use signed values for limit checking since the values can go
negative under certain circumstances.  However, sizeof() is unsigned
and forces the comparison to be unsigned, so move the comparison into
the heap_free() macros so we can ensure it is a signed comparison.
