Davi fixed a missing cast in the __put_user(), that was making timerfd return a single byte instead of the full value. Talking with Michael about the timerfd man page, we think it'd be better to use a u64 for the returned value, to align it with the eventfd implementation. This is an ABI change. The timerfd code is new in 2.6.22 and if we merge this into 2.6.23 then we should also merge it into 2.6.22.x. That will leave a few early 2.6.22 kernels out in the wild which might misbehave when a future timerfd-enabled glibc is run on them. mtk says: The difference would be that read() will only return 4 bytes, while the application will expect 8. If the application is checking the size of returned value, as it should, then it will be able to detect the problem (it could even be sophisticated enough to know that if this is a 4-byte return, then it is running on an old 2.6.22 kernel). If the application is not checking the return from read(), then its 8-byte buffer will not be filled -- the contents of the last 4 bytes will be undefined, so the u64 value as a whole will be junk.

Have put_unaligned() warn if types would be wrong for assignment, slap force-casts where needed. Cast the result of get_unaligned to typeof(*ptr).

u32* volatile cyclone_timer means volatile auto pointer to u32, which is clearly not what had been intended (we never even take the address of that variable, let alone pass it to something that could change it behind our back). u32 volatile * is what the authors apparently wanted to say, but in reality we don't need that qualifier there at all - it's (properly) only passed to iomem helpers which takes care of that stuff just fine.

Convert rel_info to host-endian before calling ip6_tnl_err(). The things become much more straightforward that way. The key observation (and the reason why that code actually worked) is that after ip6_tnl_err() we either immediately bailed out or had rel_info set to 0 or had it set to host-endian and guaranteed to hit (rel_type == ICMP_DEST_UNREACH && rel_code == ICMP_FRAG_NEEDED) case. So inconsistent endianness didn't really lead to bugs, but it had been subtle and prone to breakage. New variant is saner and obviously safe.
