[PATCH] memory hotadd fixes: not-aligned memory hotadd handling fix
ioresouce handling code in memory hotplug allows not-aligned memory hot add. But when memmap and other memory structures are initialized, parameters should be aligned. (if not aligned, initialization of mem_map will do wrong, it assumes parameters are aligned.) This patch fix it. And this patch allows ioresource collision check to handle -EEXIST.
