The patch titled
AFS/AF_RXRPC: Miscellaneous fixes
has been removed from the -mm tree. Its filename was
afs-af_rxrpc-miscellaneous-fixes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: AFS/AF_RXRPC: Miscellaneous fixes
From: David Howells <dhowells@xxxxxxxxxx>
Make miscellaneous fixes to AFS and AF_RXRPC:
(*) Make AF_RXRPC select KEYS rather than RXKAD or AFS_FS in Kconfig.
(*) Don't use FS_BINARY_MOUNTDATA.
(*) Remove a done 'TODO' item in a comemnt on afs_get_sb().
(*) Don't pass a void * as the page pointer argument of kmap_atomic() as this
breaks on m68k. Patch from Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>.
(*) Use match_*() functions rather than doing my own parsing.

If you say Y here, you will get an experimental Andrew File System
driver. It currently only supports unsecured read-only AFS access.
