However, the full list of errors isn't that unmanageable, so I'm following up with a digested list...drivers/net/ethernet/sfc/efx.c:646:3: error: call to '__compiletime_assert_648' declared with attribute error: BUILD_BUG_ON failed: sizeof(struct efx_rx_page_state) + EFX_PAGE_IP_ALIGN + EFX_RX_USR_BUF_SIZE > PAGE_SIZE / 2: 2 errors in 2 logs v3.10-rc1/s390x/s390-allyesconfig v3.10-rc1/s390x/s390-allmodconfig
that seems to a BUILD_BUG_ON that only triggers on s390, because we have L1_CACHE_BYTES defined with 256 bytes... which seems to be more than any other architecture has. There was a different network driver that had a similar BUILD_BUG_ON, but it got removed. Right, it was the igb driver: http://comments.gmane.org/gmane.linux.network/261378
