Linus, Andrew,

Attached is the hugetlbpage patch for 2.5.48 containing following main 
changes:

1) Bug fixes (mainly in the unsuccessful attempts of hugepages).
2) Removal of Radix Tree field in key structure (as it is not needed).
3) Include the IPC_LOCK for permission to use hugepages.
4) Increment the key_counts during forks.

thanks,
rohit
