+ * Calculate ram split, for memory below and above 4G. It's a bit

+ *
+ * - Traditional split is 3.5G (lowmem = 0xe0000000). This is the
+ * default value for max_ram_below_4g now.
+ *
+ * - Then, to gigabyte align the memory, we move the split to 3G
+ * (lowmem = 0xc0000000). But only in case we have to split in
+ * the first place, i.e. ram_size is larger than (traditional)
+ * lowmem. And for new machine types (gigabyte_align = true)
+ * only, for live migration compatibility reasons.
+ *
+ * - Next the max-ram-below-4g option was added, which allowed to
+ * reduce lowmem to a smaller value, to allow a larger PCI I/O
+ * window below 4G. qemu doesn't enforce gigabyte alignment here,
+ * but prints a warning.
+ *
+ * - Finally max-ram-below-4g got updated to also allow raising lowmem,
+ * so legacy non-PAE guests can get as much memory as possible in
+ * the 32bit address space below 4G.
+ *
+ * Examples:
+ * qemu -M pc-1.7 -m 4G (old default) -> 3584M low, 512M high
