Whether it is a 32- or 64-bit kernel, it has a 4K page size. If that were not true, the rx_mtu reduction would not have triggered. I have additional information obtained from a kmemleak kernel. Driver p54usb and mac80211 do not show any memory leaks, at least in STA mode. I tested this by running normal traffic for about 15 minutes, and then rmmod'ed p54usb. If kernel leaks are the problem, then they are arising from hostapd. Userland memory leaks can be checked with valgrind.
