 * Memory caches are used to preallocate memory ahead of various MMU flows,
 * e.g. page fault handlers.  Gracefully handling allocation failures deep in
 * MMU flows is problematic, as is triggering reclaim, I/O, etc... while
 * holding MMU locks.  Note, these caches act more like prefetch buffers than
 * classical caches, i.e. objects are not returned to the cache on being freed.
 *
 * The @capacity field and @objects array are lazily initialized when the cache
 * is topped up (__kvm_mmu_topup_memory_cache()).
