Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

Since commit 71810db27c1c853b33 (modversions: treat symbol CRCs
as 32 bit quantities) R_ALPHA_REFLONG relocations can be required
to load modules. This implements it.

Makes it easier to handle init vs core cleanly, though the change is
fairly invasive across random architectures.
It simplifies the rbtree code immediately, however, while keeping the
core data together in the same cachline (now iff the rbtree code is
enabled).

This patch removes all the module loader hook implementations in the
architecture specific code where the functionality is the same as that
now provided by the recently added default hooks.

arch/alpha/kernel/module.c:process_reloc_for_got(), which figures out how big
the .got section for a module should be, appears to be confusing r_offset (the
file offset that the relocation needs to be applied to) with r_addend (the
offset of the relocation's actual target address from the address of the
relocation's symbol). Because of this, one .got entry is allocated for each
relocation instead of one each unique symbol/addend.
In the module I am working with, this causes the .got section to be almost 10
times larger than it needs to be (75544 bytes instead of 7608 bytes). As the
.got is accessed with global-pointer-relative instructions, it needs to be
within the 64k gp "zone", and a 75544 byte .got clearly does not fit. The
result of this is that relocation overflows are detected during module load
and the load is aborted.
Change struct got_entry/process_reloc_for_got to fix this.

This skips the GP-loading function prologue (two instructions: 8 bytes)
on BRSGP linkage correctly, fixing an oops on alpha while loading the
aic7xxx driver.

Larger modules fail to load with the message "Relocation overflow vs
section 17", or some other section number.
This failure happens with GPRELHIGH relocation, which is *signed* short,
but relocation overflow check in module.c doesn't take into account the
sign extension.

From: Rusty Russell <rusty@rustcorp.com.au>, David Mosberger
The patch below updates the other platforms with module_arch_cleanup().
Also, I added more debug output to kernel/module.c since I found it useful
to be able to see the final section layout.
