Add missing init section definitions

2008-02-19T20:00:18+00:00

When adding __devinitconst etc. the __initconst variant
were missed.
Add this one and proper definitions for .head.text for use
in .S files.
The naming .head.text is preferred over .text.head as the
latter will conflict for a function named head when introducing
-ffunctions-sections.

Remove __INIT_REFOK and __INITDATA_REFOK

2008-02-03T07:58:07+00:00

Commit 312b1485fb509c9bc32eda28ad29537896658cb8 made __INIT_REFOK expand
into .section .section ".ref.text", "ax".  Since the assembler doesn't
tolerate stuttering in the source that broke all MIPS builds.

Since with this change Sam downgraded __INIT_REFOK to just a backward
compat thing and there being only a single use in the MIPS arch code the
best solution is to delete both of __INIT_REFOK and __INITDATA_REFOK (which
was equally broken) being unused anyway these can be deleted.

Introduce new section reference annotations tags: ref, refdata, __refconst

2008-01-28T22:21:19+00:00

Today we have the following annotations for functions/data
referencing __init/__exit functions / data:

__init_refok     => for init functions
__initdata_refok => for init data
__exit_refok     => for exit functions

There is really no difference between the __init and __exit
versions and simplify it and to introduce a shorter annotation
the following new annotations are introduced:

__ref      => for functions (code) that
              references __*init / __*exit
__refdata  => for variables
__refconst => for const variables

Whit this annotation is it more obvious what the annotation
is for and there is no longer the arbitary division
between __init and __exit code.

The mechanishm is the same as before - a special section
is created which is made part of the usual sections
in the linker script.

We will start to see annotations like this:

-static struct pci_serial_quirk pci_serial_quirks[] = {
+static const struct pci_serial_quirk pci_serial_quirks[] __refconst = {
-----------------
-static struct notifier_block __cpuinitdata cpuid_class_cpu_notifier =
+static struct notifier_block cpuid_class_cpu_notifier __refdata =
----------------
-static int threshold_cpu_callback(struct notifier_block *nfb,
+static int __ref threshold_cpu_callback(struct notifier_block *nfb,

[The above is just random samples].

Note: No modifications were needed in modpost
to support the new sections due to the newly introduced
blacklisting.

Use separate sections for dev/cpu/__mem code/data

2008-01-28T22:21:17+00:00

Introducing separate sections for __dev* (HOTPLUG),
__cpu* (HOTPLUG_CPU) and __mem* (MEMORY_HOTPLUG)
allows us to do a much more reliable Section mismatch
check in modpost. We are no longer dependent on the actual
configuration of for example HOTPLUG.

This has the effect that all users see much more
Section mismatch warnings than before because they
were almost all hidden when HOTPLUG was enabled.
The advantage of this is that when building a piece
of code then it is much more likely that the Section
mismatch errors are spotted and the warnings will be
felt less random of nature.

compiler.h: introduce __section()

Add a new helper: __section() that makes a section definition
much shorter and more readable.

store __setup_str_* in a more compact way

2007-10-17T15:42:56+00:00

__setup_str_* are referenced only during boot, hence there's no need to
waste image space for aligning these strings (with the aim of improving
performance).

Add assembler equivalents to __init{,date}_refok

2007-10-16T16:42:49+00:00

I need __INIT_REFOK to fix a MODPOST warning for a few MIPS configs which
have to call init code from .text very early in the game due to bootloader
issues.  __INITDATA_REFOK is just for consistency.
