The Cadence GEM is based on the MACB Ethernet controller but has a few small changes with regards to register and bitfield placement. This patch detects the presence of a GEM by reading the module ID register and setting a flag appropriately.

Create a common macb_platform_data for macb that both at91 and avr32 can use. In future we can use this to support other architectures that use the same IP block with the macb driver. v2: rename eth_platform_data to macb_platform_data and allow at91_ether to share the platform data with macb.

由 Javier Martinez Canillas 提交于
The IRQF_SAMPLE_RANDOM flag is marked as deprecated and will be removed. Every input point to the kernel's entropy pool have to better document the type of entropy source it is. drivers/char/random.c now implements a set of interfaces that can be used for devices to collect enviromental noise. IRQF_SAMPLE_RANDOM will be replaced with these add_*_randomness exported functions. Network drivers are not a good source of entropy. They use as a source of entropy essentially a remote host. Which means that the source of entropy can be potentially controlled by an attacker. Also, with heavy workloads the entropy decreases due to less hardware interrupts happening thanks to irq mitigation and NAPI. If a system relies in its network interface as a entropy source it has a false sense of security. Systems that don't have devices whose drivers are good sources of entropy, should either use a hardware random number generator or feed the kernel's entropy pool from userspace using other sources of entropy such as EGD, video_entropyd, timer_entropyd and audio-entropyd.

On a busy network, the macb driver could get stuck in the interrupt handler, quickly triggering the watchdog, due to a confluence of factors: 1. macb_poll re-enables interrupts unconditionally, even when it will be called again because it exhausted its rx budget 2. macb_interrupt only disables interrupts after scheduling macb_poll, but scheduling fails when macb_poll is already scheduled because it didn't call napi_complete 3. macb_interrupt loops until the interrupt status register is clear, which will never happen in this case if the driver doesn't disable the RX interrupt Since macb_interrupt runs in interrupt context, this effectively locks up the machine, triggering the hardware watchdog. This issue was readily reproducible on a flooded network with a modified 2.6.27.48 kernel. The same problem appears to still be in the 2.6.36-rc8 driver code, so I am submitting this patch against that version. I have not tested this version of the patch except to make sure the kernel compiles. Signed-off-by: NJoshua Hoke <joshua.hoke@sixnet.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The NETPOLL API requires that interrupts remain disabled in netpoll_send_skb(). The use of "A functions set" in the NETPOLL API callbacks causes the interrupts to get enabled and can lead to kernel instability. The solution is to use "B functions set" to prevent the irqs from getting enabled while in netpoll_send_skb(). A functions set: local_irq_disable()/local_irq_enable() spin_lock_irq()/spin_unlock_irq() spin_trylock_irq()/spin_unlock_irq() B functions set: local_irq_save()/local_irq_restore() spin_lock_irqsave()/spin_unlock_irqrestore() spin_trylock_irqsave()/spin_unlock_irqrestore() Signed-off-by: NDongdong Deng <dongdong.deng@windriver.com> Acked-by: NMatt Mackall <mpm@selenic.com> Signed-off-by: NDavid S.
