x86: aperture_64.c: corner case wrong
If
fix == 0, aper_enabled == 1, gart_fix_e820 == 0
if (!fix && !aper_enabled)
return;
if (gart_fix_e820 && !fix && aper_enabled) {
if (e820_any_mapped(aper_base, aper_base + aper_size,
E820_RAM)) {
/* reserve it, so we can reuse it in second kernel */
printk(KERN_INFO "update e820 for GART\n");
add_memory_region(aper_base, aper_size, E820_RESERVED);
update_e820();
}
return;
}
/* different nodes have different setting, disable them all atfirst*/
we'll fall back here and disable all the settings, even when they were
all consistent.
What about this? (I hope it compiles...)
