7a3a16fe7d pata_legacy: don't call ata_host_detach() after initialization failure
ata_host_detach() detaches an attached port and shouldn't be called on
a port which hasn't been attached yet.  pata_legacy incorrectly calls
ata_host_detach() on unattached port after initialization failure
causing oops.  Fix it.

69c3683ca7 netconsole: avoid null pointer dereference at show_local_mac()
This patch avoids a null pointer dereference when we read local_mac 
for netconsole in configfs and shows default local mac address
value.

A null pointer dereference occurs when we call show_local_mac() via 
local_mac entry in configfs before we setup the content of netpoll
using netpoll_setup().

b5c15fc004 [IPV6]: Fix reversed local_df test in ip6_fragment
I managed to reverse the local_df test when forward-porting this
patch so it actually makes things worse by never fragmenting at
all.

Thanks to David Stevens for testing and reporting this bug.

Bill Fink pointed out that the local_df setting is also the wrong
way around.

4a0962abd1 dentries: Extract common code to remove dentry from lru
Extract the common code to remove a dentry from the lru into a new function
dentry_lru_remove().

Two call sites used list_del() instead of list_del_init().  AFAIK the
performance of both is the same.  dentry_lru_remove() does a list_del_init().

As a result dentry->d_lru is now always empty when a dentry is freed.

329c97f0af One less parameter to __d_path
All callers to __d_path pass the dentry and vfsmount of a struct path to
__d_path.  Pass the struct path directly, instead.

ac748a09fc Make set_fs_{root,pwd} take a struct path
In nearly all cases the set_fs_{root,pwd}() calls work on a struct
path. Change the function to reflect this and use path_get() here.

4ac9137858 Embed a struct path into struct nameidata instead of nd->{dentry,mnt}
This is the central patch of a cleanup series. In most cases there is no good
reason why someone would want to use a dentry for itself. This series reflects
that fact and embeds a struct path into nameidata.

Together with the other patches of this series
- it enforced the correct order of getting/releasing the reference count on
  <dentry,vfsmount> pairs
- it prepares the VFS for stacking support since it is essential to have a
  struct path in every place where the stack can be traversed
- it reduces the overall code size:

without patch series:
   text    data     bss     dec     hex filename
5321639  858418  715768 6895825  6938d1 vmlinux

with patch series:
   text    data     bss     dec     hex filename
5320026  858418  715768 6894212  693284 vmlinux

This patch:

Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.
