This reverts commit 3c2e7f7de3240216042b61073803b61b9b3cfb22.
Initializing the mapping from MTRR to PAT values was reported to
fail nondeterministically, and it also caused extremely slow boot
(due to caching getting disabled---bug 103321) with assigned devices.

As reported by Dmitry Vyukov, we really shouldn't do ipc_addid() before
having initialized the IPC object state. Yes, we initialize the IPC
object in a locked state, but with all the lockless RCU lookup work,
that IPC object lock no longer means that the state cannot be seen.
We already did this for the IPC semaphore code (see commit e8577d1f0329:
"ipc/sem.c: fully initialize sem_array before making it visible") but we
clearly forgot about msg and shm.

Netfilter/IPVS updates for net-next
The following pull request contains Netfilter/IPVS updates for net-next
containing 90 patches from Eric Biederman.
The main goal of this batch is to avoid recurrent lookups for the netns
pointer, that happens over and over again in our Netfilter/IPVS code. The idea
consists of passing netns pointer from the hook state to the relevant functions
and objects where this may be needed.
You can find more information on the IPVS updates from Simon Horman's commit
merge message:
c3456026adc0 ("Merge tag 'ipvs2-for-v4.4' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/ipvs-next").
Exceptionally, this time, I'm not posting the patches again on netdev, Eric
already Cc'ed this mailing list in the original submission. If you need me to
make, just let me know.

====================
net: switchdev: use specific switchdev_obj_*
This patchset changes switchdev add, del, dump operations from this:
int (*switchdev_port_obj_add)(struct net_device *dev,
struct switchdev_obj *obj,
struct switchdev_trans *trans);
int (*switchdev_port_obj_del)(struct net_device *dev,
struct switchdev_obj *obj);
int (*switchdev_port_obj_dump)(struct net_device *dev,
struct switchdev_obj *obj);
to something similar to the notifier_call callback of a notifier_block:
int (*switchdev_port_obj_add)(struct net_device *dev,
enum switchdev_obj_id id,
const void *obj,
struct switchdev_trans *trans);
int (*switchdev_port_obj_del)(struct net_device *dev,
enum switchdev_obj_id id,
const void *obj);
int (*switchdev_port_obj_dump)(struct net_device *dev,
enum switchdev_obj_id id, void *obj,
int (*cb)(void *obj));
This allows the caller to pass and expect back a specific switchdev_obj_*
structure (e.g. switchdev_obj_fdb) instead of the generic switchdev_obj one.
This will simplify pushing the callback function down to the drivers.
The first 3 patches get rid of the dev parameter of the dump callback, since it
is not always neeeded (e.g. vlan_dump) and some drivers (such as DSA drivers)
may not have easy access to it.
Patches 4 and 5 implement the change in the switchdev operations and its users.
Patch 6 extracts the inner switchdev_obj_* structures from switchdev_obj and
removes this last one.
v2: fix error spotted by kbuild (extra ';' inline switchdev_port_obj_dump).

The net_device associated to a dump operation does not have to be passed

This happens because __s64 is by default defined as "long" on ppc64,
not as "long long". However, to fix these warnings, it's possible to
define the __SANE_USERSPACE_TYPES__ so that __s64 gets defined to
"long long" on ppc64, too.

Both new_steering_entry() and existing_steering_entry() return values
based on their success or failure, but currently they fall through
silently. This can make troubleshooting difficult, as we were unable
to tell which one of these two functions returned errors or
specifically what code was returned. This patch remedies that
situation by passing the return codes to err, which is returned by
mlx4_qp_attach_common() itself.
This also addresses a leak in the call to mlx4_bitmap_free() as well.

The modular driver supports only one card, just like the built-in

Note that this limitation is a problem which affects all Nubus card

====================
net: L3 master device
The VRF device is essentially a Layer 3 master device used to associate
netdevices with a specific routing table and to influence FIB lookups
via 'ip rules' and controlling the oif/iif used for the lookup.
This series generalizes the VRF into L3 master device, l3mdev. Similar
to switchdev it has a Kconfig option and separate set of operations
in net_device allowing it to be completely compiled out if not wanted.
The l3mdev methods rely on the 'master' aspect and use of
netdev_master_upper_dev_get_rcu to retrieve the master device from a
given netdevice if it is enslaved to an L3_MASTER.
The VRF device is converted to use the l3mdev operations. At the end the
vrf_ptr is no longer and removed, as are all direct references to VRF.
The end result is a much simpler implementation for VRF.
Thanks to Nikolay for suggestions (eg., use of the master linkage which
is the key to making this work) and to Roopa, Andy and Shrijeet for
early reviews.
v3
- added license header to l3mdev.c
- export symbols in l3mdev.c for use with GPL modules
- removed netdevice header from l3mdev.h (not needed) and fixed
typo in comment
v2
- rebased to top of net-next
- addressed Niks comments (checking master, removing extra lines, and
flipping the order of patches 1 and 2)

While auditing TCP stack for upcoming 'lockless' listener changes,
I found I had to change fastopen_init_queue() to properly init the object
before publishing it.
Otherwise an other cpu could try to lock the spinlock before it gets
properly initialized.
Instead of adding appropriate barriers, just remove dynamic memory
allocations :
- Structure is 28 bytes on 64bit arches. Using additional 8 bytes
for holding a pointer seems overkill.
- Two listeners can share same cache line and performance would suffer.
If we really want to save few bytes, we would instead dynamically allocate
whole struct request_sock_queue in the future.
