The driver will send some commands to firmware during the
initialization. Currently these commands are sent asynchronously,
which means that we firstly insert all of them to a pre-allocated
command queue, and then start to process them one by one. The
command queue will soon be exhausted if we keep adding new
initialization commands.
This issue can be resolved by sending initialization commands
synchronously because each command is consumed and the buffer is
recycled before queuing next command.

We currently use percpu order-0 pages in __netdev_alloc_frag
to deliver fragments used by __netdev_alloc_skb()
Depending on NIC driver and arch being 32 or 64 bit, it allows a page to
be split in several fragments (between 1 and 8), assuming PAGE_SIZE=4096
Switching to bigger pages (32768 bytes for PAGE_SIZE=4096 case) allows :
- Better filling of space (the ending hole overhead is less an issue)
- Less calls to page allocator or accesses to page->_count
- Could allow struct skb_shared_info futures changes without major
performance impact.
This patch implements a transparent fallback to smaller
pages in case of memory pressure.
It also uses a standard "struct page_frag" instead of a custom one.

Pull GPIO fix from Linus Walleij:
"A late GPIO fix: Roland Stigge found a problem in the LPC32xx driver
where a callback ignores one of its arguments. It needs to go into
stable too so sending this upstream immediately."
* tag 'gpio-fixes-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio:
gpio-lpc32xx: Fix value handling of gpio_direction_output()
One (missing spinlock init) was only introduced recently.
The other has been present as long as raid10 has been supported,
so is tagged for -stable.

Pull EDAC fixes from Mauro Carvalho Chehab:
"Three edac fixes at the memory enumeration logic:
- i3200_edac: Fixes a regression at the memory rank size, when the
memorias are dual-rank;
- i5000_edac: Fix a longstanding bug when calculating the memory
size: before Kernel 3.6, the memory size were right only
with one specific configuration;
- sb_edac: Fixes a bug since the initial release of the driver:
with 16GB DIMMs, there's an overflow at the memory size,
causing the number of pages per dimm (an unsigned value)
to have the highest bit equal to 1, effectively mangling
the memory size.
The third bug can potentially affect the error decoding logic as well."

The LAN8710/LAN8720 chips do have broken the "FlexPWR" smart power-saving
capability. Enabling it leads to the PHY not being able to detect Link when
cold-started without cable connected. Thus, make sure this is disabled.

Linux tunnels were written before RFC6040 and therefore never
implemented the corner case of ECN getting set in the outer header
and the inner header not being ready for it.
Section 4.2. Default Tunnel Egress Behaviour.
o If the inner ECN field is Not-ECT, the decapsulator MUST NOT
propagate any other ECN codepoint onwards. This is because the
inner Not-ECT marking is set by transports that rely on dropped
packets as an indication of congestion and would not understand or
respond to any other ECN codepoint [RFC4774]. Specifically:
* If the inner ECN field is Not-ECT and the outer ECN field is
CE, the decapsulator MUST drop the packet.
* If the inner ECN field is Not-ECT and the outer ECN field is
Not-ECT, ECT(0), or ECT(1), the decapsulator MUST forward the
outgoing packet with the ECN field cleared to Not-ECT.
This patch moves the ECN decap logic out of the individual tunnels
into a common place.
It also adds logging to allow detecting broken systems that
set ECN bits incorrectly when tunneling (or an intermediate
router might be changing the header).
Overloads rx_frame_error to keep track of ECN related error.
Thanks to Chris Wright who caught this while reviewing the new VXLAN
tunnel.
This code was tested by injecting faulty logic in other end GRE
to send incorrectly encapsulated packets.
