Pull intel MID cleanups from Peter Anvin:
"Miscellaneous cleanups to the intel-mid code merged earlier in this
merge window"
* 'x86-intel-mid-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86, intel-mid: Cleanup some platform code's header files
x86, intel-mid: Add missing 'void' to functions without arguments
x86: Don't add new __cpuinit users to Merrifield platform code

platform_ipc.h and platform_msic.h are wrongly declaring functions as
external and with 'weak' attribute. This patch does a cleanup on those
header files.
It should have no functional change.

This patch adds missing 'void' to functions that doesn't receive

Commit bc20aa48bbb3068224a1c91f8332971fdb689fad ("x86, intel-mid:
Add Merrifield platform support") added new instances of __cpuinit
usage. We removed this a couple versions ago; we now want to remove
the compat no-op stubs. Introducing new users is not what we want to
see at this point in time, as it will break once the stubs are gone.
This also fixes an out of sync __init vs. __cpuinit -- as the former
is real, and the latter is a no-op; hence it would have been a section
mismatch.

Some SoC have MMIO regions that are shared across orthogonal
subsystems. This commit implements a possible solution for the
thread-safe access of such regions through a spinlock-protected API.
Concurrent access is protected with a single spinlock for the
entire MMIO address space. While this protects shared-registers,
it also serializes access to unrelated/unshared registers.
We add relaxed and non-relaxed variants, by using writel_relaxed and writel,
respectively. The rationale for this is that some users may not require
register write completion but only thread-safe access to a register.

Commit 65939301acdb (arm: set initrd_start/initrd_end for fdt scan)
caused the FDT initrd_start and initrd_end to override the

parameter. With this patch initrd_start and initrd_end will be
overridden if phys_initrd_start and phys_initrd_size are set by the
kernel initrd= parameter.

__und_usr_thumb function deals with thumb2 opcodes. In case of BE
image, it needs to byteswap half word thumb2 encoded instructions
before further processing them.
Without this fix BE image user-land thread executing first VFP
instruction encoded in thumb2 fails with SIGILL, because kernel
does not recognize instruction and does not enable VFP.

The commit 1d3ee88ae0d605629bf369
(bonding: add netlink attributes to slave link dev)
has add rtmsg_ifinfo() in bond_set_active_slave() and
bond_set_backup_slave(), so the two function need to
called in RTNL lock, but bond_loadbalance_arp_mon()
only calling these functions in RCU, warning message
will occurs.
fix this by add a new function bond_slave_state_change(),
which will reset the slave's state after slave link check,
so remove the bond_set_xxx_slave() from the cycle and only
record the slave_state_changed, this will call the new
function to set all slaves to new state in RTNL later.

A file descriptor opened for /dev/net/tun and a tun device are
connected with ioctl. Though understanding the connection is
important for trouble shooting, no way is given to a user to know
the connected device for a given file descriptor at userland.
This patch adds a new fdinfo field for the device name connected to
a file descriptor opened for /dev/net/tun.
Here is an example of the field:
# lsof | grep tun
qemu-syst 4565 qemu 25u CHR 10,200 0t138 12921 /dev/net/tun
...
# cat /proc/4565/fdinfo/25
pos: 138
flags: 0104002
iff: vnet0
# ip link show dev vnet0
8: vnet0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 ...
changelog:
v2: indent iff just like the other fdinfo fields are.
v3: remove unused variable.
Both are suggested by David Miller <davem@davemloft.net>.

DT: net: davinci_emac: couple more properties actually optional
Though described as required, couple more properties in the DaVinci EMAC
binding are actually optional, as the driver will happily function without them.
The patchset is against DaveM's 'net.git' tree this time.
[1/2] DT: net: davinci_emac: "ti,davinci-rmii-en" property is actually optional
[2/2] DT: net: davinci_emac: "ti,davinci-no-bd-ram" property is actually optional

The "ti,davinci-no-bd-ram" property for the DaVinci EMAC binding simply can't be
required one, as it's boolean (which means it's absent if false).
While at it, document the property better...

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 user tried to change generic options using "ethtool -s" command, while SFP
module is plugged out or during module detection, the command would have failed
with "Unsupported port type" message. The fix is to ignore the port option in
case it's same as the current port configuration.

RxRPC fixes
Here are some small AF_RXRPC fixes.
(1) Fix a place where a spinlock is taken conditionally but is released
unconditionally.
(2) Fix a double-free that happens when cleaning up on a checksum error.
(3) Fix handling of CHECKSUM_PARTIAL whilst delivering messages to userspace.

skb_kill_datagram() does not dequeue the skb when MSG_PEEK is unset.
This leaves a free'd skb on the queue, resulting a double-free later.

o Bound checks for number of receive descriptors and number of recieve rings.
Both of these have off-by-one errors.
o Vlan list was getting re-initialized in case of adapter reset.
o Tx queue was timing out because of missing start queue for a corresponding
netif_tx_disable.
o Loopback test failed because driver was not setting linkup variable
while handling link events.

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.

due to fragmented memory.

There is race condition when call netif_napi_add() after
register_netdevice(), as ->open() can be called without napi initialized
and trigger BUG_ON() on napi_enable(), like on below messages:
