The first part of huge pile. Mostly it's untangling nameidata handling,
digging towards the pieces that kill intents and cleaning pathname
resolution in general. ->permission() sanitizing and sysctl procfs
treatment rewrite needed for it. A bunch of descriptor handling fixes.
Plus part of assorted patched from the last cycle sent by other folks.
A _lot_ more is still pending; this is what I'd managed to pull into
a series by this point. Please, pull from
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6.git/ for-linus

Shortlog:
Al Viro (24):
beginning of sysctl cleanup - ctl_table_set
allow delayed freeing of ctl_table_header
sysctl: make sure that /proc/sys/net/ipv4 appears before per-ns ones
sysctl: keep track of tree relationships
sanitize proc_sysctl
sanitize ->permission() prototype
permission checks for chdir need special treatment only on the last step
kill altroot
fix MAY_CHDIR/MAY_ACCESS/LOOKUP_ACCESS mess
pass MAY_OPEN to vfs_permission() explicitly
more nameidata removal: exec_permission_lite() doesn't need it
take noexec checks to very few callers that care
kill nameidata passing to permission(), rename to inode_permission()
preparation to __user_walk_fd cleanup
sanitize __user_walk_fd() et.al.
new (local) helper: user_path_parent()
don't pass nameidata to gfs2_lookupi()
don't pass nameidata to __ncp_lookup_validate()
f_count may wrap around
get rid of __user_path_lookup_open
get rid of indirect users of namei.h
remove remaining namei_{32,64}.h crap
get rid of corner case in dup3() entirely
fix RLIM_NOFILE handling
