5933048c69 module: cleanup FIXME comments about trimming exception table entries.
Everyone cut and paste this comment from my original one.  We now do
it generically, so cut the comments.

7c03d653cd powerpc/mm: Introduce MMU features
We're soon running out of CPU features and I need to add some new
ones for various MMU related bits, so this patch separates the MMU
features from the CPU features.  I moved over the 32-bit MMU related
ones, added base features for MMU type families, but didn't move
over any 64-bit only feature yet.

b9754568ef powerpc: Remove dead module_find_bug code
Doing some various "make randconfig", I came across an error when
CONFIG_BUG was not set:

arch/powerpc/kernel/module.c: In function 'module_find_bug':
arch/powerpc/kernel/module.c:111: error: increment of pointer to unknown structure
arch/powerpc/kernel/module.c:111: error: arithmetic on pointer to an incomplete type
arch/powerpc/kernel/module.c:112: error: dereferencing pointer to incomplete type

Looking further into this, I found that module_find_bug, defined in
powerpc arch code, is not called anywhere, so this just removes it.

There is a static module_find_bug in lib/bug.c but that is a separate issue.

2d1b202762 powerpc: Fixup lwsync at runtime
To allow for a single kernel image on e500 v1/v2/mc we need to fixup lwsync
at runtime.  On e500v1/v2 lwsync causes an illop so we need to patch up
the code.  We default to 'sync' since that is always safe and if the cpu
is capable we will replace 'sync' with 'lwsync'.

We introduce CPU_FTR_LWSYNC as a way to determine at runtime if this is
needed.  This flag could be moved elsewhere since we dont really use it
for the normal CPU_FTR purpose.

Finally we only store the relative offset in the fixup section to keep it
as small as possible rather than using a full fixup_entry.
