(updated, rolled up) make section names compatible with -ffunction-sections -fdata-sections

Hi Andrew,

Here is the update against current Linus tree,
rolled up into one patch.

James Bottomley suggested a different naming scheme:
instead of swapping parts (.text.head -> .head.text), prepend .kernel to our special section names. This patch implements his idea.

ppc and v850 are dropped per comments from arch people. parisc and x86 had minor fixes. x86 fix added proper executable bits to a section:

-.section ".text.head"
+.section ".kernel.text.head","ax",@progbits

Does arch/m68k/kernel/sun3-head.S need the same fix?

The patch is run-tested on x86_64.

I would like to ask arch maintainers to ACK/NAK this patch, and Andrew to act accordingly.

Changelog follows:

The purpose of these patches is to make kernel buildable with "gcc -ffunction-sections -fdata-sections".

The problem is that with -ffunction-sections -fdata-sections gcc creates sections like .text.head and .data.nosave whenever someone has innocuous code like this:

static void head(...) {...}

or this:

int f(...) { static int nosave; ... }

somewhere in the kernel.

Kernel linker script is confused by such names and puts these sections in wrong places.

This patch renames all "magic" section names used by kernel to not have this format, eliminating the possibility of such collisions.

The purpose of these patches is to make kernel buildable with "gcc -ffunction-sections -fdata-sections".

The problem is that with -ffunction-sections -fdata-sections gcc creates sections like .text.head and .data.nosave whenever someone has innocuous code like this:

static void head(...) {...}

or this:

int f(...) { static int nosave; ... }

somewhere in the kernel.

Kernel linker script is confused by such names and puts these sections in wrong places.

This patch renames all "magic" section names used by kernel to not have this format, eliminating the possibility of such collisions.

Hi Andrew,

Here is the update against current Linus tree,
rolled up into one patch.

James Bottomley suggested a different naming scheme:
instead of swapping parts (.text.head -> .head.text), prepend .kernel to our special section names. This patch implements his idea.

ppc and v850 are dropped per comments from arch people. parisc and x86 had minor fixes. x86 fix added proper executable bits to a section:

-.section ".text.head"
+.section ".kernel.text.head","ax",@progbits

Does arch/m68k/kernel/sun3-head.S need the same fix?

The patch is run-tested on x86_64.

I would like to ask arch maintainers to ACK/NAK this patch, and Andrew to act accordingly.

Changelog follows:
