2009-08-28ipw2200: firmware DMA loading reworkZhu Yi
Bartlomiej Zolnierkiewicz reported an atomic order-6 allocation failure for ipw2200 firmware loading in kernel 2.6.30. High order allocation is likely to fail and should always be avoided. The patch fixes this problem by replacing the original order-6 pci_alloc_consistent() with an array of order-1 pages from a pci pool. This utilized the ipw2200 DMA command blocks (up to 64 slots). The maximum firmware size support remains the same (64*8K).

2009-08-23drivers/net: fixed drivers that support netpoll use ndo_start_xmit()Dongdong Deng
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: Dongdong Deng <dongdong.deng@windriver.com> Acked-by: Matt Mackall <mpm@selenic.com> Signed-off-by: David S.

2009-08-23E100: fix interaction with swiotlb on X86.Krzysztof Hałasa
E100 places it's RX packet descriptors inside skb->data and uses them with bidirectional streaming DMA mapping. Data in descriptors is accessed simultaneously by the chip (writing status and size when a packet is received) and CPU (reading to check if the packet was received). This isn't a valid usage of PCI DMA API, which requires use of the coherent (consistent) memory for such purpose. Unfortunately e100 chips working in "simplified" RX mode have to store received data directly after the descriptor. Fixing the driver to conform to the API would require using unsupported "flexible" RX mode or receiving data into a coherent memory and using CPU to copy it to network buffers. This patch, while not yet making the driver conform to the PCI DMA API, allows it to work correctly on X86 with swiotlb (while not breaking other architectures).

2009-08-21rtl8187: always set MSR_LINK_ENEDCA flag with RTL8187BHerton Ronaldo Krzesinski
RTL8187B always needs MSR_LINK_ENEDCA flag to be set even when it is in no link mode, otherwise it'll not be able to associate when this flag is not set after the change "mac80211: fix managed mode BSSID handling". By accident, setting BSSID of AP before association makes 8187B to successfuly associate even when ENEDCA flag isn't set, which was the case before the mac80211 change. But now the BSSID of AP we are trying to associate is only available after association is successful, and any attempt to associate without the needed flag doesn't work.

2009-08-20ibm_newemac: emac_close() needs to call netif_carrier_off()Petri Gynther
When ibm_newemac netdev instance is shutdown with "ifconfig down", the netdev interface does not go properly down. netif_carrier_ok() keeps returning TRUE even after "ifconfig down". The problem can be seen when ibm_newemac instances are slaves of a bonding interface. The bonding interface code uses netif_carrier_ok() to determine the link status of its slaves. When ibm_newemac slave is shutdown with "ifconfig down", the bonding interface won't detect any link status change because netif_carrier_ok() keeps returning TRUE.
