Hi Kazuyasu-san,
I just stumbled across this thread and saw your many valuable contributions (e.g. kgdb support, swap support) some of which are not yet merged into the nios2mmu Linux Kernel branch on sopc.
Currently I'm in the process of merging the unstable branch (nios2 w/o MMU) into nios2mmu and also cleaning up some edges and ends of the code along the way.
I'd really like to get your contributions into the tree and thus would like to Cc: you on the patches I send to the nios2-dev mailinglist for review. Could you send me your email address via private message for that?
Thanks a lot
Tobias
