Fix bug in sata_mv for cases where the IOMMU layer has merged SG entries to larger than 64KB. They need to be split up before being sent to the driver. Just for simplicity's sake, split up at 64K boundary instead of 64K size, since that's what the common code does anyway.

Remove unneeded check that caused problems with jumbo frame sizes. The check was recently added and is wrong. When using jumbo frames the sky2 driver does fragmentation, so rx_data_size is less than mtu.

They contain 64-bit instructions so wouldn't work on 32-bit kernels or 32-bit hardware. Since there are no users, blow them away. They probably were only ever created because there are atomic_sub_if_positive and atomic_dec_if_positive which exist only for sake of semaphores. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

This driver erroneously zeros dev->tx_queue_len, since mp->tx_ring_size has not yet been initialized. Actually, the driver shouldn't modify tx_queue_len at all and should leave the value set by alloc_etherdev(), currently 1000.

For the case where the source is not aligned modulo 8 we don't use load-twins to suck the data in and this kills performance since normal loads allocate in the L1 cache (unlike load-twin) and thus big memcpys swipe the entire L1 D-cache. We need to allocate a register window to implement this properly, but that actually simplifies a lot of things as a nice side-effect. Signed-off-by: David S. Miller <davem@davemloft.net>

TCP V4 sequence numbers are 32bits, and RFC 793 assumed a 250 KHz clock. In order to follow network speed increase, we can use a faster clock, but we should limit this clock so that the delay between two rollovers is greater than MSL (TCP Maximum Segment Lifetime : 2 minutes) Choosing a 64 nsec clock should be OK, since the rollovers occur every 274 seconds.

This is followup to Patrick's patch. A little optimization to enqueue routine allows to remove artificial limitation on queue length. Plus, testing showed that hash function used by SFQ is too bad or even worse. It does not even sweep the whole range of hash values. Switched to Jenkins' hash.

For some reason old binutils genertate larger headers so increase the text offset of the vdso to avoid linker errors. Roland McGrath explains: "There are extra symbols in the '.dynsym' section that are responsible for the size difference (They also cause corresponding inflation in '.gnu.version') Older ld's wrongly generated these unneeded symbols in .dynsym. This was fixed not all that long ago (2006); binutils-2.17.50.0.6 might be the first fixed version, but I have not verified for sure where the cutoff was. The unneeded symbols et al from old ld add almost 700 bytes excess. This limits fairly tightly the amount by which the actual text and data in the vDSO can grow in the future without pushing the whole file over 4kb. If it does grow later on, we should consider changing the layout with a config option or something to pack it better without that padding, when building the kernel with newer binutils."

On a POWER6 machine running 2.6.23-rc8 I sometimes see the following error: xics_set_affinity: No online cpus in the mask 00000000,00000000,00000000,00000001 for irq 20 In a desperate attempt to get a changelog entry in 2.6.23, I took a look into it. It turns out we are passing a real and not a virtual irq into get_irq_server. This works for the case where hwirq < NR_IRQS and we set virq = hwirq. In my case however hwirq = 590082 and we try and access irq_desc[590082], slightly past the end at 512 entries. Lucky we ship lots of memory with our machines.
