The kallsyms routines (module_symbol_name, lookup_module_* etc) disable
preemption to walk the modules rather than taking the module_mutex:
this is because they are used for symbol resolution during oopses.
This works because there are synchronize_sched() and synchronize_rcu()
in the unload and failure paths. However, there's one case which doesn't
have that: the normal case where module loading succeeds, and we free
the init section.
We don't want a synchronize_rcu() there, because it would slow down
module loading: this bug was introduced in 2009 to speed module
loading in the first place.
Thus, we want to do the free in an RCU callback. We do this in the
simplest possible way by allocating a new rcu_head: if we put it in
the module structure we'd have to worry about that getting freed.

Nothing needs the module pointer any more, and the next patch will
call it from RCU, where the module itself might no longer exist.
Removing the arg is the safest approach.
This just codifies the use of the module_alloc/module_free pattern
which ftrace and bpf use.

Archs have been abusing module_free() to clean up their arch-specific
allocations. Since module_free() is also (ab)used by BPF and trace code,
let's keep it to simple allocations, and provide a hook called before
that.
This means that avr32, ia64, parisc and s390 no longer need to implement
their own module_free() at all. avr32 doesn't need module_finalize()
either.

ACCESS_ONCE might fail with specific compilers for non-scalar accesses.
Here is a set of patches to tackle that problem.
The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data structure
is larger than the machine word size memcpy is used and a warning is emitted.
The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar
types.
This merge does not yet contain a patch that forces ACCESS_ONCE to work only
on scalar types. This is targetted for the next merge window as Linux next
already contains new offenders regarding ACCESS_ONCE vs. non-scalar types.

strcmp was lost when all other string functions were removed,
but we still have an optimized version for this on CRISv32,
so any driver built as a module would not have access to this symbol.
In a similar manner, we had optimized versions of
csum_partial_copy_from_user and __do_clear_user
but no exported symbols for them, breaking bunch of other drivers
when built as a module.
At the same time, move EXPORT_SYMBOL(__copy_user) and
EXPORT_SYMBOL(__copy_user_zeroing) C-files so it's
located together with the function definition.

Pull x86 apic updates from Thomas Gleixner:
"After stopping the full x86/apic branch, I took some time to go
through the first block of patches again, which are mostly cleanups
and preparatory work for the irqdomain conversion and ioapic hotplug
support.
Unfortunaly one of the real problematic commits was right at the
beginning, so I rebased this portion of the pending patches without
the offenders.
It would be great to get this into 3.19. That makes reworking the
problematic parts simpler. The usual tip testing did not unearth any
issues and it is fully bisectible now.
I'm pretty confident that this wont affect the calmness of the xmas
season.
Changes:
- Split the convoluted io_apic.c code into domain specific parts
(vector, ioapic, msi, htirq)
- Introduce proper helper functions to retrieve irq specific data
instead of open coded dereferencing of pointers
- Preparatory work for ioapic hotplug and irqdomain conversion
- Removal of the non functional pci-ioapic driver
- Removal of unused irq entry stubs
- Make native_smp_prepare_cpus() preemtible to avoid GFP_ATOMIC
allocations for everything which is called from there.
- Small cleanups and fixes"
