[Intrepid] SRU Update to 2.6.27.12

[Stefan Bader]

https://bugs.launchpad.net/bugs/321472

Note: contains two ABI bumpers:
* iwlwifi: use GFP_KERNEL to allocate Rx SKB memory
* fs: symlink write_begin allocation context fix

The second patch cannot be modified to avoid the ABI bump. Since the ABI has to 
be changed, I re-applied the following patch from the 2.6.27.10 update:
* iwlagn: fix RX skb alignment
