If st_kim_start() fails registered protocols should be removed. This is
done by calling st_reg_complete(), which as comment states is called
with spin lock held. But in st_register() when st_kim_start fails it
is called without holding spin lock, creating possibility of concurrent
access to st_gdata data members.
Hold spin lock while calling st_reg_complete if st_kim_start() fails.

The current code would attempt to negotiate a different protocol version if
the current negotiation timed out. This triggers an assert in the host (on debug
builds). Avoid this by negotiating a newer version only if the host properly
rejects the current version being negotiated.

This patch adds support for virtual IOMMU to the vmci module.  We switch
to DMA consistent mappings for guest queuepair and doorbell pages that
are passed to the device.  We still allocate each page individually,
since there's no guarantee that we'll get a contiguous block of physical
for an entire queuepair (especially since we allow up to 128 MiB!).

Also made the split between guest and host in the kernelIf struct much
clearer.  Now it's obvious which fields are which.

In the previous QUERY_PAGES command version we used one command to get the
required amount of boot, init and post init pages.  The new version uses the
op_mod field to specify whether the query is for the required amount of boot,
init or post init pages. In addition the output field size for the required
amount of pages increased from 16 to 32 bits.

In MANAGE_PAGES command the input_num_entries and output_num_entries fields
sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10.

In the pages request event the num_pages field also changed to 32 bits.

In the HCA-capabilities-layout the size and location of max_qp_mcg field has
been changed to support 24 bits.

This patch isn't compatible with firmware versions < 5; however, it  turns out that the

NULL pointer dereference in tg3 driver when !netdev || !netif_running(netdev)
condition is met and netdev is NULL. Then, the jump to the 'done' label
calls dev_close() with a netdevice that is NULL. Therefore, only call
dev_close() when we have a netdevice, but one that is not running.

It's always a bad idea to poll on HW bits without a timeout.

The i.MX28 RTC can be easily brought into a state in which the RTC is
not running (until after a power-on-reset) and thus the status bits
which are polled in the driver won't ever change.

This patch prevents the kernel from getting stuck in this case.

Fix a BUG which can trigger when direct-IO is used with AOE.

As discussed previously, the fact that some users of the block layer
provide bios that point to pages with a zero _count means that it is not
OK for the network layer to do a put_page on the skb frags during an
skb_linearize, so the aoe driver gets a reference to pages in bios and
puts the reference before ending the bio.  And because it cannot use
get_page on a page with a zero _count, it manipulates the value
directly.

It is not OK to increment the _count of a compound page tail, though,
since the VM layer will VM_BUG_ON a non-zero _count.  Block users that
do direct I/O can result in the aoe driver seeing compound page tails in
bios.  In that case, the same logic works as long as the head of the
compound page is used instead of the tails.  This patch handles compound
pages and does not BUG.

It relies on the block layer user leaving the relationship between the
page tail and its head alone for the duration between the submission of
the bio and its completion, whether successful or not.

Initially I improperly set a boundary for maximum number of input
packets to process on NAPI poll ("work") so it might be more than
expected amount ("weight").

This was really harmless but seeing WARN_ON_ONCE on every device boot is
not nice. So trivial fix ("<" instead of "<=") is here.

There might be a crash as during shutdown flow CNIC might try
to access resources already freed by bnx2x.
Change bnx2x_close() into dev_close() in __bnx2x_remove (shutdown flow)
to guarantee CNIC is notified of the device's change of status.

PTE write access error  might occur in MF_ALLOWED mode when IOMMU
is active. The patch adds rmmod HSI indicating to MFW to stop
running queries which might trigger this failure.

Add locking to protect different statistics flows from
running simultaneously.
This in order to serialize statistics requests sent to FW,
otherwise two outstanding queries may cause FW assert.
