zeal 5c427ff9e4 KS8695: fix ks8695_rx() unreasonable action.
ks8695_rx() will call refill_buffers() for every incoming packet.
Its not necessary. We just need do it after finishing receiving thing.
And the 'RX dma engine' is in the same situation.
This blocks our user space application. The following patch may fix it.

zeal fa6cae143d KS8695: fix ks8695_rx_irq() bug.
ks8695 rx irq is edge-level. Before arriving at irq handler, the
corresponding status bit has been clear(irq's ack).
So we should not check it after that.

Figo.zhang 31b73ab3ef NET/KS8695: add support NAPI for Rx
Add support NAPI Rx API for KS8695NET driver.

v2, change the Rx function to NAPI.

in <KS8695X Integrated Multi-port Gateway Solution Register Description
 v1.0>:

Interrupt Enable Register (offset 0xE204)
Bit29 : WAN MAC Receive Interrupt Enable
Bit16 : LAN MAC Receive Interrupt Enable

Interrupt Status Register (Offset 0xF208)
Bit29: WAN MAC Receive Status
Bit16: LAN MAC Receive Status

see arch/arm/mach-ks8695/devices.c:
ks8695_wan_resources[] and ks8695_lan_resources[]
have IORESOURCE_IRQ , it have define the RX irq,
for wan, irq = 29; for lan ,irq = 16.
so we can do this read the interrupt status:

unsigned long mask_bit = 1 << ksp->rx_irq;
status = readl(KS8695_IRQ_VA + KS8695_INTST);

Uwe Kleine-König 78a9c9c974 register at91_ether using platform_driver_probe
at91ether_probe lives in .init.text, so using platform_driver_register
to register it is wrong because binding a device after the init memory
is discarded (e.g. via sysfs) results in an oops.

As requested by David Brownell platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially.
This saves some memory, but devices registered after the driver is
probed are not bound (probably there are none) and binding via sysfs
isn't possible.

Russell King 8cfd9e923b [ARM] RiscPC: Fix etherh oops
The 8390 driver was structured by Al Viro to allow the flexibility
required by platforms.  lib8390.c contains the core code which drivers
explicitly include:
- 8390.c includes lib8390.c to provide the standard ISA based driver.
- etherh.c includes it with the accessors defined for RiscPC platforms,
  where it is addressed via the MMIO accessors with a device dependent
  register spacing.

Other platform drivers do something similar.

However, b9a9b4b caused the kernel to contain not only the etherh
private build of lib8390 (included in etherh.c) but also lib8390.c
itself, and referred the new net_device_ops methods to the ISA version.
The result of this is is not pretty:

Uwe Kleine-König fb22d72782 [NET] am79c961a: fix spin_lock usage
spin_lock functions take a pointer to the lock, not the lock itself.
This error was noticed by compiling ebsa110_defconfig for linux-rt where
the locking functions obviously are more picky about their arguments.
