I2C devices do not have any form of ID as PCI or USB devices have.
No driver uses "MODULE_DEVICE_TABLE(i2c, ...)" because it doesn't
make sense. So we can get rid of struct i2c_device_id and the
associated support code.Signed-off-by: Jean Delvare

With the net namespaces many code leaved the __init section,
thus making the kernel occupy more memory than it did before.
Since we have a config option that prohibits the namespace
creation, the functions that initialize/finalize some netns
stuff are simply not needed and can be freed after the boot.Currently, this is almost not noticeable, since few calls
are no longer in __init, but when the namespaces will be
merged it will be possible to free more code. I propose to
use the __net_init, __net_exit and __net_initdata "attributes"
for functions/variables that are not used if the CONFIG_NET_NS
is not set to save more space in memory.The exiting functions cannot just reside in the __exit section,
as noticed by David, since the init section will have
references on it and the compilation will fail due to modpost
checks. These references can exist, since the init namespace
never dies and the exit callbacks are never called. So I
introduce the __exit_refok attribute just like it is already
done with the __init_refok.Signed-off-by: Pavel Emelyanov

SSB is an SoC bus used in a number of embedded devices. The most
well-known of these devices is probably the Linksys WRT54G, but there
are others as well. The bus is also used internally on the BCM43xx
and BCM44xx devices from Broadcom.This patch also includes support for SSB ID tables in modules, so
that SSB drivers can be loaded automatically.Signed-off-by: Michael Buesch

The Xtensa architecture places literal pools in sections separate
from the instructions. The corresponsing text sections, therefore,
reference the .literal section, and we have to suppress those
warnings.The naming convention defines the name for a literal
section as .SECTION.literal, unless .SECTION is .text. In that case
the name is only .literal. Using strncmp() instead of strcmp()
to compare the from-section with .SECTION.init.refok in pattern 0
should not cause any regressions for other architectures.We also need to suppress warnings for two informational
sections (.xt.lit and .xt.prop) used by the Xtensa architecture.Signed-off-by: Chris Zankel

In the whitelist function of modpost now use the same
check to identify init_section as in other places of modpost.
This has the effect that we now recognize sections named

Previously we did do the check on the .o files used to link
vmlinux but that failed to find questionable references across
the .o files.
Create a dedicated vmlinux.o file used only for section mismatch checks
that uses the defualt linker script so section does not get renamed.The vmlinux.o may later be used as part of the the final link of vmlinux
but for now it is used fo section mismatch only.
For a defconfig build this is instant but for an allyesconfig this

There's a special .cranges section that is almost always generated,
with data being moved to the appropriate section by the linker at a later
stage.To give a bit of background, sh64 has both a native SHmedia instruction
set (32-bit instructions) and SHcompact (which is compatability with
normal SH -- 16-bit, a massively reduced register set, etc.). code ranges
are emitted when we're using the 32-bit ABI, but not the 64-bit one.It is a special staging section used solely by binutils where code with
different flags get placed (more specifically differing flags for input
and output sections), before being lazily merged by the linker.The closest I've been able to find to documentation is:
http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/ld/emultempl/sh64elf.em?rev=1.10&content-type=text/x-cvsweb-markup&cvsroot=srcIt's an array of 8-byte Elf32_CRange structure given in
http://sources.redhat.com/cgi-bin/cvsweb.cgi/src/bfd/elf32-sh64.h?rev=1.4&content-type=text/x-cvsweb-markup&cvsroot=src
that describes for which ISA a range is used.Silence the warnings by allowing references from .init.text to .cranges.
The following warnings are fixed:

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
