Subject[PATCH v2 0/8] Mark literal strings in __init / __exit code
Date
This is v2 of the patch series initially posted here:

https://lkml.org/lkml/2014/6/22/149

I've integrated Joe's idea of also providing printk_init() /
printk_exit() wrappers for code that cannot (or doesn't want to) be
converted to the pi_*() / pe_*() wrappers.

Patches 4 and 5 are cleanup patches I stumbled over while changing the
corresponding code to make use of the new pi_*() helpers.

This version addresses the symbol filtering issue, by filtering the
pseudo symbols in kallsyms (patch 8). This removes them even in the
KALLSYMS_ALL case.

I've changed a few more files, pushing up the memory moved from .rodata
to .init.rodata to ~3 kB. This should free up a page after init for
almost any x86 system.

Comments?


Mathias Krause (8):
init.h: Add __init_str / __exit_str macros
printk: Provide pi_<level> / pe_<level> macros for __init / __exit
code
x86, acpi: Mark __init strings as such
x86, mm: Make x86_init.memory_setup() return a const char *
x86, mm: early_panic() - pass on the message as string
x86, mm: e820 - mark __init strings as such
x86: setup - mark __init strings as such
kallsyms: exclude pseudo symbols for __init / __exit strings
