This reverts commit 3a9f987b3141f086de27832514aad9f50a53f754.
With all the files that are real modules now having module.h
explicitly called out for inclusion, and no reliance on any
implicit presence of module.h assumed, we should no longer
need this workaround.

Recent commit "irq: Track the owner of irq descriptor" in
commit ID b6873807a7143b7 placed module.h into linux/irq.h
but we are trying to limit module.h inclusion to just C files
that really need it, due to its size and number of children
includes. This targets just reversing that include.
Add in the basic "struct module" since that is all we really need
to ensure things compile. In theory, b687380 should have added the
module.h include to the irqdesc.h header as well, but the implicit
module.h everywhere presence masked this from showing up. So give
it the "struct module" as well.
As for the C files, irqdesc.c is only using THIS_MODULE, so it
does not need module.h - give it export.h instead. The C file
irq/manage.c is now (as of b687380) using try_module_get and
module_put and so it needs module.h (which it already has).
Also convert the irq_alloc_descs variants to macros, since all
they really do is is call the __irq_alloc_descs primitive.
This avoids including export.h and no debug info is lost.

These two small inlines make calls to try_module_get() and
module_put() which would force us to keep module.h present
within yet another common include header. We can avoid this
by turning them into macros. The hci_dev_hold construct
is patterned off of raw_spin_trylock_irqsave() in spinlock.h

This file was using the module get/put functions in two simple inline
functions. But module_get/put were only within scope because of
the implicit presence of module.h being everywhere.
Rather than add module.h to another file in include/ -- which is
exactly the thing we are trying to avoid, simply convert these
one-line functions into a define, as per what was done for the
device_schedule_callback() in commit 523ded71de0c5e669733.

The implicit presence of module.h everywhere meant that this header
also was getting moduleparam.h which defines struct kernel_param.
Since it only needs to know that kernel_param is a struct, call that
out instead of adding an include of moduleparam.h -- to get rid of this:
include/net/netfilter/nf_conntrack.h:316: warning: 'struct kernel_param' declared inside parameter list
include/net/netfilter/nf_conntrack.h:316: warning: its scope is only this definition or declaration, which is probably not what you want

The <linux/module.h> pretty much brings in the kitchen sink along
with it, so it should be avoided wherever reasonably possible in
terms of being included from other commonly used <linux/something.h>
files, as it results in a measureable increase on compile times.
The worst culprit was probably device.h since it is used everywhere.
This file also had an implicit dependency/usage of mutex.h which was
masked by module.h, and is also fixed here at the same time.
There are over a dozen other headers that simply declare the
struct instead of pulling in the whole file, so follow their lead
and simply make it a few more.
Most of the implicit dependencies on module.h being present by
these headers pulling it in have been now weeded out, so we can
finally make this change with hopefully minimal breakage.

The original implementations reference THIS_MODULE in an inline.
We could include <linux/export.h>, but it is better to avoid chaining.
Fortunately someone else already thought of this, and made a similar
inline into a #define in <linux/device.h> for device_schedule_callback(),
[see commit 523ded71de0] so follow that precedent here.
Also bubble up any __must_check that were used on the prev. wrapper inline
functions up one to the real __register functions, to preserve any prev.
sanity checks that were used in those instances.

The <linux/crypto.h> (which is in turn in common headers
like tcp.h) wants to use module_name() in an inline fcn.
But having all of <linux/module.h> along for the ride is
overkill and slows down compiles by a measureable amount,
since it in turn includes lots of headers.
Since the inline is never used anywhere in the kernel[1],
we can just remove it, and then also remove the module.h
include as well.
In all the many crypto modules, there were some relying on
crypto.h including module.h -- for them we now explicitly
call out module.h for inclusion.
[1] git grep shows some staging drivers also define the same
static inline, but they also never ever use it.

This file had an include of module.h which was probably added
in relation to this line:
#define ACPI_EXPORT_SYMBOL(symbol) EXPORT_SYMBOL(symbol);
However, we really expect symbol exporters to grab export.h
themselves, and since this is only a define, we can remove
the module.h include without aclinux.h itself causing any
compile issues.

This file has a define MODULE_ALIAS_MISCDEV which in turn will
use the MODULE_ALIAS define, but only if the former is explicitly
used by modular device driver code (and such code should be
already including module.h).
Delete the include, since module.h is such a giant thing that we
don't want it implicitly sneaking into compiles where it isn't
specifically required.
