Commit 5f77898de1 does not completely
fix the problem of handling allocations with irqs disabled.. The
below patch on top of it fixes the problem completely.
Based on review by "Ivan Vecera" <ivecera@redhat.com>..
"
Small note, the root of the problem was that non-atomic allocation was requested with IRQs disabled. Your patch description does not contain wwhy were the IRQs disabled.
The function bnad_mbox_irq_alloc incorrectly uses 'flags' var for two different things, 1) to save current CPU flags and 2) for request_irq
call.
First the spin_lock_irqsave disables the IRQs and saves _all_ CPU flags (including one that enables/disables interrupts) to 'flags'. Then the 'flags' is overwritten by 0 or 0x80 (IRQF_SHARED). Finally the spin_unlock_irqrestore should restore saved flags, but these flags are now either 0x00 or 0x80. The interrupt bit value in flags register on x86 arch is 0x100.
This means that the interrupt bit is zero (IRQs disabled) after spin_unlock_irqrestore so the request_irq function is called with disabled interrupts.

Fix the condition where PS3 network RX hangs when no network
TX is occurring by calling gelic_card_enable_rxdmac() during
RX_DMA_CHAIN_END event processing.
The gelic hardware automatically clears its RX_DMA_EN flag when
it detects an RX_DMA_CHAIN_END event. In its processing of
RX_DMA_CHAIN_END the gelic driver is required to set RX_DMA_EN
(with a call to gelic_card_enable_rxdmac()) to restart RX DMA
transfers. The existing gelic driver code does not set
RX_DMA_EN directly in its processing of the RX_DMA_CHAIN_END
event, but uses a flag variable card->rx_dma_restart_required
to schedule the setting of RX_DMA_EN until next inside the
interrupt handler.
It seems this delayed setting of RX_DMA_EN causes the hang since
the next RX interrupt after the RX_DMA_CHAIN_END event where
RX_DMA_EN is scheduled to be set will not occur since RX_DMA_EN
was not set. In the case were network TX is occuring, RX_DMA_EN
is set in the next TX interrupt and RX processing continues.

Overview:
Support mapping of priorities to traffic classes and
traffic classes to transmission queues ranges in the net device.
The queue ranges are (count, offset) pairs relating to the txq
array.
This can be done via DCBX negotiation or by kernel.
As a result Enhanced Transmission Selection (ETS) and Priority Flow
Control (PFC) are supported between L2 network traffic classes.
Mapping:
This patch uses the netdev_set_num_tc, netdev_set_prio_tc_map and
netdev_set_tc_queue functions to map priorities to traffic classes
and traffic classes to transmission queue ranges.
This mapping is performed by bnx2x_setup_tc function which is
connected to the ndo_setup_tc.
This function is always called at nic load where by default it
maps all priorities to tc 0, and it may also be called by the
kernel or by the bnx2x upon DCBX negotiation to modify the mapping.
rtnl lock:
When the ndo_setup_tc is called at nic load or by kernel the rtnl
lock is already taken. However, when DCBX negotiation takes place
the lock is not taken. The work is therefore scheduled to be
handled by the sp_rtnl task.
Fastpath:
The fastpath structure of the bnx2x which was previously used
to hold the information of one tx queue and one rx queue was
redesigned to represent multiple tx queues, one for each traffic
class.
The transmission queue supplied in the skb by the kernel can no
longer be interpreted as a straightforward index into the fastpath
structure array, but it must rather be decoded to the appropriate
fastpath index and the tc within that fastpath.
Slowpath:
The bnx2x's queue object was redesigned to accommodate multiple
transmission queues. The queue object's state machine was enhanced
to allow opening multiple transmission-only connections on top of
the regular tx-rx connection.
Firmware:
This feature relies on the tx-only queue feature introduced in the
bnx2x 7.0.23 firmware and the FW likewise must have the bnx2x multi
cos support.

There is no software fallback implemented for SCTP or FCoE checksumming,
and so it should not be passed on by software devices like bridge or bonding.
For VLAN devices, this is different. First, the driver for underlying device
should be prepared to get offloaded packets even when the feature is disabled
(especially if it advertises it in vlan_features). Second, devices under
VLANs do not get replaced without tearing down the VLAN first.
This fixes a mess I accidentally introduced while converting bonding to
ndo_fix_features.
NETIF_F_SOFT_FEATURES are removed from BOND_VLAN_FEATURES because they
are unused as of commit 712ae51afd.

Software defined version number is not stable enough to be used
in device type naming scheme. The patch changes it to use implicit
soc name for spi device type definition. In this way, we can easily
align the naming scheme with device tree binding, which comes later.
It removes fifosize from spi_imx_data and adds devtype there, so that
fifosize can be set in an inline function according to devtype.
Also, cpu_is_mx can be replaced by inline functions checking devtype.

spi_imx0_7_config into mx31_config. As a result, type SPI_IMX_VER_0_7

It also renames function spi_imx0_4_reset to mx31_reset to keep
