bnx2x did not set dump->version in its .get_dump_flag() method.
Let's set it to BNX2X_DUMP_VERSION. It's not a particularly nice

deterministic.

There is no need to initialize the dump data with zeros.
data is allocated with vzalloc, so it's already zero-filled.
More importantly, the memset is harmful, because dump->len (the length
requested by userspace) can be bigger than the allocated buffer (whose
size is determined by asking the driver's .get_dump_flag method).

As reported by "kbuild test robot" there were some errors and warnings
on attempt to build kernel with "make ARCH=powerpc allmodconfig".
And this patch addresses both errors and warnings.
Below is a list of introduced changes:
1. Fix compile-time errors (misspellings in "dma_unmap_single") on PPC.
2. Use DMA address instead of "skb->data" as a pointer to data buffer.
This fixed warnings on pointer to int conversion on 64-bit systems.
3. Re-implemented initial allocation of Rx buffers in "arc_emac_open" in
the same way they're re-allocated during operation (receiving packets).
So once again DMA address could be used instead of "skb->data".
4. Explicitly use EMAC_BUFFER_SIZE for Rx buffers allocation.

When the EEH error is the result of a fenced host bridge, MMIO accesses
can be very slow (milliseconds) to timeout and return all 1's,
thus causing the driver various timeout loops to take way too long and
trigger soft-lockup warnings (in addition to taking minutes to recover).
It might be worthwhile to check if for any of these cases, ffffffff is
a valid possible value, and if not, bail early since that means the HW
is either gone or isolated. In the meantime, checking that the PCI channel
is offline would be workaround of the problem.

We therefore drop frames more than needed.
This patch tries order-3, order-2, order-1 and finally order-0

memory gets fragmented.
By using larger pages, and avoiding unnecessary get_page()/put_page()

false sharing on struct page.
Also use GFP_KERNEL allocations in initialization path, as allocating 12

The lifetime of an irq_cpu_rmap is odd: we have to allocate it before

As a result of this asymmetry, it was omitted from some failure paths.
On another failure path, we could try to remove IRQ handlers we
had not yet installed.
Move the irq_cpu_rmap allocation and freeing alongside IRQ handler
installation and removal, in efx_nic_{init,fini}_interrupts().

Zero pointer in rx_skb is how respective rxq_deinit() finds out out that a skb
slot is unallocated. If rxq_refill() fails (e.g. on OOM condition), subsequent
teardown would result in an attempt to kfree() invalid pointers.

Zero pointer in rx_skb or tx_skb is how respective *_deinit() functions find
out that a skb slot is unallocated. If *_init() functions unsuccessfully return
after the allocation (e.g. when subsequent dma_alloc_coherent() is not
successful), this would result in attempt to kfree() invalid pointers.

Due to some hardware integration issue, CPSW sliver modules requires a
reset across suspend/resume cycle for a successful clock gating to
CPGMAC (CPSW and Davinci MDIO) in AM335x PG1.0.
This issue is fixed in PG2.x, though to support suspend/resume on PG1.0
this reset is required.

Commits 4c09eed9 (net: fec: Enable imx6 enet checksum acceleration) and
baa70a5c (net: fec: enable pause frame to improve rx prefomance for 1G
network) introduced functionality into the FEC driver which is not
supported on MCF5272. The registers used to implement this functionality
do not exist on MCF5272. Since register defines for MCF5272 are separate
from register defines for other chips, building images for MCF5272 fails
as follows.
fec_main.c: In function 'fec_restart':
fec_main.c:520:8: error: 'FEC_RACC' undeclared (first use in this function)
fec_main.c:585:3: error: 'FEC_R_FIFO_RSEM' undeclared (first use in this function)

fec_main.c:591:3: error: 'FEC_OPD' undeclared (first use in this function)
Adding the missing register defines is not an option, since the registers
do not exist on MCF5272. Disable the added functionality for MCF5272 builds.

The ath9k Kconfig conflict was a change of a Kconfig option name right
next to the deletion of another option.
The xen-netback conflict was overlapping changes involving the
handling of the notify list in xen_netbk_rx_action().
Batman conflict resolution provided by Antonio Quartulli, basically
keep everything in both conflict hunks.
The nl80211 conflict is a little more involved. In 'net' we added a
dynamic memory allocation to nl80211_dump_wiphy() to fix a race that
Linus reported. Meanwhile in 'net-next' the handlers were converted
to use pre and post doit handlers which use a flag to determine
whether to hold the RTNL mutex around the operation.
However, the dump handlers to not use this logic. Instead they have
to explicitly do the locking. There were apparent bugs in the
conversion of nl80211_dump_wiphy() in that we were not dropping the
RTNL mutex in all the return paths, and it seems we very much should
be doing so. So I fixed that whilst handling the overlapping changes.
To simplify the initial returns, I take the RTNL mutex after we try
to allocate 'tb'.

The change set of 4305b541, "[SK_BUFF]: Convert skb->end to sk_buff_data_t"
converted skb->end from pointer type to sk_buff_data_t.
The pointed value should be accessed via skb_end_pointer().
Since arm arch doesn't define NET_SKBUFF_DATA_USES_OFFSET,
skb->end is effectively pointer. So it doesn't cause a real problem.
But this patch is good for consistency.
Found by inspection. Compile tested only.
