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.Signed-off-by: Jonas Bonn

Some modules may end up with R_SH_NONE relocs with the right combination
of compiler/kernel config (specifically dwarf unwinder), so simply trap
and ignore them instead of letting them get down to the error path.Reported-by: Carmelo AMOROSO

With all the recent module loading cleanups, we've minimized the code
that sits under module_mutex, fixing various deadlocks and making it
possible to do most of the module loading in parallel.However, that whole conversion totally missed the rather obscure code
that adds a new module to the list for BUG() handling. That code was
doubly obscure because (a) the code itself lives in lib/bugs.c (for
dubious reasons) and (b) it gets called from the architecture-specific
"module_finalize()" rather than from generic code.Calling it from arch-specific code makes no sense what-so-ever to begin
with, and is now actively wrong since that code isn't protected by the
module loading lock any more.So this commit moves the "module_bug_{finalize,cleanup}()" calls away
from the arch-specific code, and into the generic code - and in the
process protects it with the module_mutex so that the list operations
are now safe.Future fixups:
- move the module list handling code into kernel/module.c where it
belongs.
- get rid of 'module_bug_list' and just use the regular list of modules
(called 'modules' - imagine that) that we already create and maintain
for other reasons.Reported-and-tested-by: Thomas Gleixner

This enables us to build the dwarf unwinder both with modules enabled and
disabled in addition to reducing code size in the latter case. The
helpers are also consolidated, and modified to resemble the BUG module
helpers.Signed-off-by: Paul Mundt

Pass a module's .eh_frame section to the DWARF unwinder at module load
time so that the section's FDEs and CIEs can be registered with the
DWARF unwinder. This allows us to unwind the stack through module code
when generating backtraces.Signed-off-by: Matt Fleming

Everyone cut and paste this comment from my original one. We now do
it generically, so cut the comments.Signed-off-by: Rusty Russell

SH-X2 extended mode TLB allows for toggling of the exec bit, so make
sure we are using the right protection bits for module space there
also.Signed-off-by: Paul Mundt

We should be calling in to the lib/bug.c module helpers, fix that up.

This is trivial, in that they're both effectively the same for the base
relocations anyways. SH-5 doesn't need the unaligned bits, and has a
few extra relocations, which are never hit on non-SH5 parts.Signed-off-by: Paul Mundt

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
