COW support in build kernels

mstone tells me that Copy-on-write support (which I would like to use in upgrades) requires git commit c53121c04317d23aa60664e08933218ef66f3ed6 from the vserver git. (git://dev.laptop.org/users/mstone/olpc-2.6). From IRC:
(02:40:52 PM) Ashsong_home: There are two fixes here, first the generic_sendpage() infrastructure that makes CoW work and the changes to olpc_defconfig that cause file permissions to be preserved across reboots on JFFS2. (02:41:24 PM) Ashsong_home: but if he adds me as a remote and runs git-remote update, he should be able to just merge the stated commits and git will do the right thing. (git remote add git://dev.laptop.org/users/mstone/olpc-2.6) (02:41:29 PM) Ashsong_home: We were trying to make this easy for him. (02:42:37 PM) Ashsong_home: (Incidentally, I think he didn't commit those changes because he wanted Dave to review the generic_sendpage stuff). (02:43:18 PM) Ashsong_home: I'm told that Dave and Herbert talked and that they agreed that since the sendpage patch was vserver-specific, Herbert was the appropriate judge of its correctness and that Andres should perform the merge. (02:43:23 PM) Ashsong_home: However, that's just hearsay.
I need working COW to keep making progress on upgrades, which I'd like to get into the builds early this week.
