Helge Deller e6b0f4f7e3 ipv6: Ensure natural alignment of const ipv6 loopback and router addresses ... [ Upstream commit 60365049cc ] On a parisc64 kernel I sometimes notice this kernel warning: Kernel unaligned access to 0x40ff8814 at ndisc_send_skb+0xc0/0x4d8 The address 0x40ff8814 points to the in6addr_linklocal_allrouters variable and the warning simply means that some ipv6 function tries to read a 64-bit word directly from the not-64-bit aligned in6addr_linklocal_allrouters variable. Unaligned accesses are non-critical as the architecture or exception handlers usually will fix it up at runtime. Nevertheless it may trigger a performance penality for some architectures. For details read the "unaligned-memory-access" kernel documentation. The patch below ensures that the ipv6 loopback and router addresses will always be naturally aligned. This prevents the unaligned accesses for all architectures.
