This patch removes pci_disable_device() from __e100_shutdown().
pci_clear_master() is enough.

Self generated skbuffs in net/can/bcm.c are setting a skb->sk reference but
no explicit destructor which is enforced since Linux 3.11 with commit
376c7311 (net: add a temporary sanity check in skb_orphan()).

This patch adds some helper functions to make sure that a destructor is
properly defined when a sock reference is assigned to a CAN related skb.
To create an unshared skb owned by the original sock a common helper function
has been introduced to replace open coded functions to create CAN echo skbs.

The loop in vxlan_gro_receive() over the current set of candidates for
coalescing was wrongly aborted once a match was found. In rare cases,
this can cause a false-positives matching in the next layer GRO checks.

Since udp_add_offload() can be called from non-sleepable context e.g
under this call tree from the vxlan driver use case:

  vxlan_socket_create() <-- holds the spinlock
  -> vxlan_notify_add_rx_port()
     -> udp_add_offload()  <-- schedules

we should allocate the udp_offloads structure in atomic manner.

When the GPIO bitbang MDIO driver is used instead of the Davinci MDIO driver
we need to configure the phy_id string differently. Otherwise this string
looks like this "gpio.6" instead of "gpio-0" and the PHY is not found when
phy_connect() is called.

 "The major piece in here is the immutable bio_ve series from Kent, the
  rest is fairly minor.  It was supposed to go in last round, but
  various issues pushed it to this release instead.  The pull request
  contains:

   - Various smaller blk-mq fixes from different folks.  Nothing major
     here, just minor fixes and cleanups.

   - Fix for a memory leak in the error path in the block ioctl code
     from Christian Engelmayer.

   - Header export fix from CaiZhiyong.

   - Finally the immutable biovec changes from Kent Overstreet.  This
     enables some nice future work on making arbitrarily sized bios
     possible, and splitting more efficient.  Related fixes to immutable

Chris Mason reported a NULL pointer derefernence in generic_getxattr()
that was due to sb->s_xattr being NULL.

The reason is that the nfs #ifdef's for ACL support were misplaced, and
the nfs3 inode operations had the xattr operation pointers set up, even
though xattrs were not actually supported.  As a result, the xattr code
was being called without the infrastructure having been set up.

Move the #ifdef's appropriately.

Commit 0abdd7a8 ("dma-debug: introduce debug_dma_assert_idle()") was
reworked to expand the overlap counter to the full range expressable by
3 tag bits, but it has a thinko in treating the overlap counter as a
pure reference count for the entry.

Instead of deleting when the reference-count drops to zero, we need to
delete when the overlap-count drops below zero.  Also, when detecting
overflow we can just test the overlap-count > MAX rather than applying
special meaning to 0.

Commit 63d0f0a3 ("mm/readahead.c:do_readhead(): don't check for
->readpage") unintentionally made do_readahead return 0 for all valid
files regardless of whether readahead was supported, rather than the
expected -EINVAL.  This gets forwarded on to userspace, and results in
sys_readahead appearing to succeed in cases that don't make sense (e.g.
when called on pipes or sockets).  This issue is detected by the LTP
readahead01 testcase.

As the exact return value of force_page_cache_readahead is currently
never used, we can simplify it to return only 0 or -EINVAL (when
readpage or readpages is missing).  With that in place we can simply
forward on the return value of force_page_cache_readahead in
do_readahead.

This patch performs said change, restoring the expected semantics.

Commit 309381fe ("mm: dump page when hitting a VM_BUG_ON using
VM_BUG_ON_PAGE") added a bunch of VM_BUG_ON_PAGE() calls.

But, most of the ones in the slub code are for _temporary_ 'struct
page's which are declared on the stack and likely have lots of gunk in
them.  Dumping their contents out will just confuse folks looking at
bad_page() output.  Plus, if we try to page_to_pfn() on them or
soemthing, we'll probably oops anyway.

Turn them back in to VM_BUG_ON()s.

On kmem_cache_create_memcg() error path we set 'err', but leave 's' (the
new cache ptr) undefined.  The latter can be NULL if we could not
allocate the cache, or pointing to a freed area if we failed somewhere
later while trying to initialize it.  Initially we checked 'err'
immediately before exiting the function and returned NULL if it was set
ignoring the value of 's':

    out_unlock:
        ...
        if (err) {
            /* report error */
            return NULL;
        }
        return s;

Recently this check was, in fact, broken by commit f717eb3a ("slab:
do not panic if we fail to create memcg cache"), which turned it to:

    out_unlock:
        ...
        if (err && !memcg) {
            /* report error */
            return NULL;
        }
        return s;

As a result, if we are failing creating a cache for a memcg, we will
skip the check and return 's' that can contain crap.  Obviously, commit
f717eb3a intended not to return crap on error allocating a cache for
a memcg, but only to remove the error reporting in this case, so the
check should look like this:

    out_unlock:
        ...
        if (err) {
            if (!memcg)
                return NULL;
            /* report error */
            return NULL;
        }
        return s;

Change parameter types of s390's compat ipc syscall from unsigned long
to compat_ulong_t to enforce zero extension of these parameters.

This is not really a bug, since s390_ipc compat syscall is only a
wrapper to the generic compat_sys_ipc() syscall, which performs correct
zero and sign extension.

This was introduced with commit 56e41d3c ("merge compat sys_ipc
instances").

Commit d5dc77bf ("consolidate compat lookup_dcookie()") coverted all
architectures to the new compat_sys_lookup_dcookie() syscall.

The "len" paramater of the new compat syscall must have the type
compat_size_t in order to enforce zero extension for architectures where
the ABI requires that the caller of a function performed zero and/or
sign extension to 64 bit of all parameters.

We got a report that the pwritev syscall does not work correctly in
compat mode on s390.

It turned out that with commit 72ec3516 ("switch compat readv/writev
variants to COMPAT_SYSCALL_DEFINE") we lost the zero extension of a
couple of syscall parameters because the some parameter types haven't
been converted from unsigned long to compat_ulong_t.

This is needed for architectures where the ABI requires that the caller
of a function performed zero and/or sign extension to 64 bit of all
parameters.
