Though described as required, the "ti,davinci-rmii-en" property for the DaVinci
EMAC binding seems actually optional, as the driver should happily work without
it; the property is not specified either in the example device node or in the
actual EMAC device node for DA850 device tree, only AM3517 one.
While at it, document the property better...

When dealing with icmp messages, the skb->data points the
ip header that triggered the sending of the icmp message.
In gre_cisco_err(), the parse_gre_header() is called, and the
iptunnel_pull_header() is called to pull the skb at the end of
the parse_gre_header(), so the skb->data doesn't point the
inner ip header.
Unfortunately, the ipgre_err still needs those ip addresses in
inner ip header to look up tunnel by ip_tunnel_lookup().
So just use icmp_hdr() to get inner ip header instead of skb->data.

This patch removes grant transfer releasing code from netfront, and uses
gnttab_end_foreign_access to end grant access since
gnttab_end_foreign_access_ref may fail when the grant entry is
currently used for reading or writing.
* clean up grant transfer code kept from old netfront(2.6.18) which grants
pages for access/map and transfer. But grant transfer is deprecated in current
netfront, so remove corresponding release code for transfer.
* fix resource leak, release grant access (through gnttab_end_foreign_access)
and skb for tx/rx path, use get_page to ensure page is released when grant
access is completed successfully.
Xen-blkfront/xen-tpmfront/xen-pcifront also have similar issue, but patches
for them will be created separately.
V6: Correct subject line and commit message.
V5: Remove unecessary change in xennet_end_access.
V4: Revert put_page in gnttab_end_foreign_access, and keep netfront change in
single patch.
V3: Changes as suggestion from David Vrabel, ensure pages are not freed untill
grant acess is ended.
V2: Improve patch comments.

But there are many more, resulting in the machine going OOM after some
days.
From looking at the TPROXY code, and with help from Florian, I see
that the memory leak is introduced in tcp_v4_early_demux():
void tcp_v4_early_demux(struct sk_buff *skb)
{
/* ... */
iph = ip_hdr(skb);
th = tcp_hdr(skb);
if (th->doff < sizeof(struct tcphdr) / 4)
return;
sk = __inet_lookup_established(dev_net(skb->dev), &tcp_hashinfo,
iph->saddr, th->source,
iph->daddr, ntohs(th->dest),
skb->skb_iif);
if (sk) {
skb->sk = sk;
where the socket is assigned unconditionally to skb->sk, also bumping
the refcnt on it. This is problematic, because in our case the skb
has already a socket assigned in the TPROXY target. This then results
in the leak I see.
The very same issue seems to be with IPv6, but haven't tested.

It happens because in bond_ab_arp_probe() we change the flags of a slave
without holding the RTNL lock.
To fix this - remove the useless curr_active_lock, RCUify it and lock RTNL
while changing the slave's flags. Also, remove bond_ab_arp_probe() from
under any locks in bond_ab_arp_mon().

Currently we're calling it from under RCU context, however we're using some
functions that require rtnl to be held.
Fix this by restructuring the locking - don't call it under any locks,
aquire rcu_read_lock() if we're sending _only_ (i.e. we have the active
slave present), and use rtnl locking otherwise - if we need to modify
(in)active flags of a slave.

Currently bond_ab_arp_probe() is always called under rcu_read_lock(),
however to work with curr_active_slave we're still holding the
curr_slave_lock.
To remove that curr_slave_lock - rcu_dereference the bond's
curr_active_slave and use it further - so that we're sure the slave won't
go away, and we don't care if it will change in the meanwhile.

Submission d9aee59 "bnx2x: Don't release PCI bars on shutdown" separated
the PCI remove and shutdown flows, but pci_disable_device() is still
being called on both.
As a result, a dev_WARN_ONCE will be hit during shutdown for every bnx2x
VF probed on a hypervisor (as its shutdown callback will be called and later
pci_disable_sriov() will call its remove callback).
This calls the pci_disable_device() only on the remove flow.

Loading ipmi_si module while bmc is disconnected, we found the timeout

A respun version of the merges for the pull request previously sent with
a few additional fixes. The last two merges were fixed up by hand since
the branches have moved on and currently have the prior merge in them.
Quite a busy release for the SPI subsystem, mostly in cleanups big and
small scattered through the stack rather than anything else:
- New driver for the Broadcom BC63xx HSSPI controller.
- Fix duplicate device registration for ACPI.
- Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA
changes upon which the transiton depends).
- Some small optimisations to reduce the amount of time we hold locks
in the datapath, eliminate some redundant checks and the size of a
spi_transfer.
- Lots of fixes, cleanups and general enhancements to drivers,
especially the rspi and Atmel drivers.

we will always get compile errors if people accidentally try the
userspace and the kernel uid and gid types. The second patch an
overlooked and unused chunk of mips code that that fails to build
after the first patch.
The code hasn't been in linux-next for long (as I was out of it and
could not sheppared the cold properly) but the patch has been around
for a long time just waiting for the day when I had finished the
uid/gid conversions. Putting the code in linux-next did find the
compile failure on mips so I took the time to get that fix reviewed
and included. Beyond that I am not too worried about errors because
all these two patches do is delete a modest amount of code"
