2007-10-03libata: fix for sata_mv >64KB DMA segmentsOlof Johansson1-7/+19
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.

2007-10-02[SPARC64]: Fix missing load-twin usage in Niagara-1 memcpy.David S. Miller3-166/+221
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 <[email protected]>

2007-10-01[TCP]: secure_tcp_sequence_number() should not use a too fast clockEric Dumazet1-4/+6
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.

2007-10-01x86_64: increase VDSO_TEXT_OFFSET for ancient binutilsAndi Kleen1-1/+1
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."

2007-10-02[POWERPC] Fix xics set_affinity codeAnton Blanchard1-1/+1
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.

2007-10-01Fix possible splice() mmap_sem deadlockLinus Torvalds1-12/+34
Nick Piggin points out that splice isn't being good about the mmap semaphore: while two readers can nest inside each others, it does leave a possible deadlock if a writer (ie a new mmap()) comes in during that nesting.

on-disk version is newer." This reverts commit b394e43e995d08821588a22561c6a71a63b4ff27. Lachlan McIlroy says: It tried to fix an issue where log replay is replaying an inode cluster initialisation transaction that should not be replayed because the inode cluster on disk is more up to date. Since we don't log file sizes (we rely on inode flushing to get them to disk) then we can't just replay all the transations in the log and expect the inode to be completely restored. We lose file size updates. Unfortunately this fix is causing more (serious) problems than it is fixing.

2007-10-01robust futex thread exit raceMartin Schwidefsky2-20/+34
Calling handle_futex_death in exit_robust_list for the different robust mutexes of a thread basically frees the mutex. Another thread might grab the lock immediately which updates the next pointer of the mutex. fetch_robust_entry over the next pointer might therefore branch into the robust mutex list of a different thread. This can cause two problems: 1) some mutexes held by the dead thread are not getting freed and 2) some mutexs held by a different thread are freed. The next point need to be read before calling handle_futex_death.
