Jean Delvare cee37ae407 i2c: Kill struct i2c_device_id
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.

Pavel Emelyanov 4665079cbb [NETNS]: Move some code into __init section when CONFIG_NET_NS=n
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.

Sam Ravnborg cb7e51d8b1 kbuild: fix modpost warnings for xtensa
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.

Tejun Heo 9281acea6a kallsyms: make KSYM_NAME_LEN include space for trailing '\0'
KSYM_NAME_LEN is peculiar in that it does not include the space for the
trailing '\0', forcing all users to use KSYM_NAME_LEN + 1 when allocating
buffer.  This is nonsense and error-prone.  Moreover, when the caller
forgets that it's very likely to subtly bite back by corrupting the stack
because the last position of the buffer is always cleared to zero.

This patch increments KSYM_NAME_LEN by one and updates code accordingly.

* off-by-one bug in asm-powerpc/kprobes.h::kprobe_lookup_name() macro
  is fixed.

* Where MODULE_NAME_LEN and KSYM_NAME_LEN were used together,
  MODULE_NAME_LEN was treated as if it didn't include space for the
  trailing '\0'.  Fix it.

Roman Zippel d8982ba1f2 kconfig: reset generated values only if Kconfig and .config agree.
Normally generated values (Kconfig entries without a prompt) are cleared as
they are regenerated anyway and so they appear as new should they become
visible and defaults work as expected (once a value is set defaults aren't
used anymore).

The detection whether a value is generated or not is only based on its
visibility status, which can quickly change for a lot of symbols by just
removing a single line from .config or adding a dependency to Kconfig as you
noticed.

The patch now suppresses this logic when .config and Kconfig aren't in sync
and .config needs to be updated, so that you can remove now a random value
from .config and oldconfig won't reask for many other values.

Jan Beulich a5eb6a502b modpost white list pattern adjustment
gcc puts data into .data.rel or .data.rel.* on some architectures (e.g.
ia64) or under certain conditions, so whatever is legal relative to
.data should also be legal for those other sections. Fixes a few
modpost warnings on ia64.

Sam Ravnborg 741f98fe29 kbuild: do section mismatch check on full vmlinux
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
add two minutes to a full build (that anyways takes ~2 hours).

Sam Ravnborg 1e29a706ee kbuild: whitelist references from variables named _timer to .init.text
arm uses a lot of ops structures named *_timer that has legitimite
references to .init.text.
So let's add this variable to the list of variables that may reference
.init.text without causing any warning.

Sam Ravnborg 92cc6b0725 kbuild: remove hardcoded _logo names from modpost
Replaced this with a __init_refok marker
in front of fb_find_logo().

I think that the __initdata marker for the logo's are
wrong but I have not justified this so I did not remove it.

Sam Ravnborg 1087247b7d kbuild: refactor code in modpost to improve maintainability
There were a great deal of overlap between the two functions

Factor out common check to a separate function and
sort entries in the original functions.

Sam Ravnborg b28242e7e3 kbuild: ignore section mismatch warnings originating from .note section
.note* sections are ELF notes, which are typically used by external
tools to examine the kernel image.  Since this is removed from any
runtime consideration, it's OK to reference any section from a .note*
section.

On i386 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.

Sam Ravnborg b70e325cfe kconfig: fix update-po-config
Massimo Maiurana <maiurana@gmail.com> reported that
update-po-config was broken:
1) spelling errors in Makefile so arch/um failed
2) UTF-8 was not supported

The following patch address the above problems.
kxgettext now append the output to the .pot file
generated by xgettext - so we have a header.
In all places UFT-8 is specifed so we now flawlessly
support UTF-8.
The Kconfig files had an empty string in a few cases -
these are now supressed in kxgettext.

With this the translators can now pick up where they left
and get it all translated.
There are ~11000 strings to be translated...

Mike Frysinger 4c6f2eb979 kbuild: add support for squashing uid/gid in gen_initramfs_list.sh
Sometimes it is useful to squash all uid's/gid's to 0:0 regardless of
current owner.  For example, in build systems that get run as arbitrary
users (uClinux-dist).  This adds a special "squash" keyword so you can do
'-g squash -u squash' and have ownership squashed to root.
