geoip: adjust geoip{4,6}_{city,region}_name prototypes for !HAVE_GEOIP
Make the return type make the functions for HAVE_GEOIP. This fixes GCC's -Wdiscarded-qualifiers warnings when building without geoip support. Fixes: 8fd19eefa46b ("geoip: Fix memory leak when using GeoIPRecord") Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

bo_rx_buffers alloc_jumbo finds the buffers already != NULL, since data (shared with page in e1000_rx_buffer->rxbuf) has been re-alloc'd, but it's garbage, or at least not what is expected when in jumbo state. This results in an unusable adapter (packets don't get through), and a NULL pointer dereference on the next call to e1000_clean_rx_ring (other mtu change, link down, shutdown): BUG: unable to handle kernel NULL pointer dereference at (null) IP: [<ffffffff81194d6e>] put_compound_page+0x7e/0x330 [...] Call Trace: [<ffffffff81195445>] put_page+0x55/0x60 [<ffffffff815d9f44>] e1000_clean_rx_ring+0x134/0x200 [<ffffffff815da055>] e1000_clean_all_rx_rings+0x45/0x60 [<ffffffff815df5e0>] e1000_down+0x1c0/0x1d0 [<ffffffff811e2260>] ? deactivate_slab+0x7f0/0x840 [<ffffffff815e21bc>] e1000_change_mtu+0xdc/0x170 [<ffffffff81647050>] dev_set_mtu+0xa0/0x140 [<ffffffff81664218>] do_setlink+0x218/0xac0 [<ffffffff814459e9>] ? nla_parse+0xb9/0x120 [<ffffffff816652d0>] rtnl_newlink+0x6d0/0x890 [<ffffffff8104f000>] ? kvm_clock_read+0x20/0x40 [<ffffffff810a2068>] ? sched_clock_cpu+0xa8/0x100 [<ffffffff81663802>] rtnetlink_rcv_msg+0x92/0x260 By setting the allocator to a dummy version, netpoll can't mess up our rx buffers. The allocator is set back to a sane value in e1000_configure_rx.
