Subject: [PATCH 01/12] powerpc: Fix the MODALIAS generation in modpost for of
 devices

Since the devices may have multiple (or none) compatible properties,
the uevent generated internally by the kernel may have multiple
"C..." entries. So the MODALIAS stored in the module must have
wilcard before and after the compatible entry.
Also, if the 'compatible' field is not used for matching, there
will be no 'C' and that must handled as well.

The previous code handled all those case incorrectly and it
"mostly" worked ... but not always.

 check-lxdialog.sh

The check-lxdialog.sh script searches for "libFOO.so" which fails on OS X, due
to their special naming of libraries like "libfoo.dylib".  This patch turns
the curses lib search into extensible loops and adds dylib as a valid
extension.

Subject: [PATCH 04/12] kbuild: make modpost section warnings clearer

Change modpost section mismatch warnings to be less confusing;
model them on the binutils linker warnings which we all know how
to interpret.

Also, fix the wrong ordering of arguments for the final case -
fromsec and refsymname were reversed.

Subject: [PATCH 05/12] kbuild: make better section mismatch reports on i386,
 arm and mips

On i386, ARM and MIPS, warn_sec_mismatch() sometimes fails to show
usefull symbol name.  This is because empty 'refsym' due to 0 r_addend
value.  This patch is to adjust r_addend value, consulting with
apply_relocate() routine in kernel code.

Without this patch:
  MODPOST vmlinux
WARNING: init/built-in.o - Section mismatch: reference to .init.text: from .text between 'rest_init' (at offset 0xf4) and 'try_name'
WARNING: mm/built-in.o - Section mismatch: reference to .init.text: from .text between 'kmem_cache_create' (at offset 0x18a39) and 'cache_reap'
WARNING: mm/built-in.o - Section mismatch: reference to .init.text: from .text between 'kmem_cache_create' (at offset 0x18a6b) and 'cache_reap'

With this patch:
  MODPOST vmlinux
WARNING: mm/built-in.o - Section mismatch: reference to .init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset 0x18a39) and 'cache_reap'
WARNING: mm/built-in.o - Section mismatch: reference to .init.text:set_up_list3s from .text between 'kmem_cache_create' (at offset 0x18a6b) and 'cache_reap'

Now modpost can detect "kernel_init" name (and whitelist it) and show
"set_up_list3s" name.

Subject: [PATCH 08/12] all-archs: consolidate .data section definition in
 asm-generic

With this consolidation we can now modify the .data
section definition in one spot for all archs.

Subject: [PATCH 09/12] kbuild: introduce __init_refok/__initdata_refok to
 supress section mismatch warnings

Throughout the kernel there are a few legitimite references
to init or exit sections. Most of these are covered by the
patterns included in modpost but a few nees special attention.
To avoid hardcoding a lot of function names in modpost introduce
a marker so relevant function/data can be marked.
When modpost see a reference to a init/exit function from
a function/data marked no warning will be issued.

Idea from: Andrew Morton <akpm@linux-foundation.org>

Subject: [PATCH 11/12] mm: fix section mismatch warnings

modpost had two cases hardcoded for mm/
Shift over to __init_refok and kill the
hardcoded function names in modpost.

This has the drawback that the functions
will always be kept no matter configuration.
With previous code the function were placed in
init section if configuration allowed it.
