Linus, please apply.
This patch:
Compatibility layer ping corruption bug (Rusty)
Sparc alignment bugfix (Rusty)
REJECT fix + TCP RST re-enable (Rusty)
ICMP REDIRECT suppression fix (Rusty)
ipqueue -W bugfixes (James Morris,
Andrew Morton)
This breaks source compatibility for x86 (but not binary
compatibility), and both source and binary compatibility for platforms
where it didn't work before anyway 8).
Rusty.
