Subject: [RFC PATCH 3/3] x86, acpi: Mark __init strings as such

Make use of the pi_<level>() helpers to mark the strings printed during
initialization for automatic release. Do so for the strings used in
command line parsing as well, by using the __init_str() macro.

Also convert the remaining printk() calls to their pr_<level> /
pi_<level> counterparts.

This moves ~1.7 kB from the .rodata section to .init.rodata.

Signed-off-by: Mathias Krause <minipli@...glemail.com>

Should the checkpatch warnings be handled, too, e.g. removing the line
breaks for strings?:

WARNING: quoted string split across lines
#421: FILE: arch/x86/kernel/acpi/boot.c:1263:
+               pi_notice("Warning: DMI blacklist says broken, but acpi "
+                         "forced\n");

I'd rather not remove the braces as it's IMHO more readable and more
consistent with the coding style with them, as this is just the start
of a huge if-else-if-.. block:

WARNING: braces {} are not necessary for single statement blocks
#453: FILE: arch/x86/kernel/acpi/boot.c:1520:
+       if (strcmp(arg, _("off")) == 0) {
                disable_acpi();
        }
