| Subject | [PATCH] xen/balloon: Use the correct sizeof when declaring frame_list |

The type of the item in frame_list is xen_pfn_t which is not an unsigned long on ARM but an uint64_t. With the current computation, the size of frame_list will be 2 * PAGE_SIZE rather than PAGE_SIZE. I bet it's just mistake when the type has been switched from "unsigned long" to "xen_pfn_t" in commit 965c0aaafe3e75d4e65cd4ec862915869bde3abd "xen: balloon: use correct type for frame_list".
