This behavior has been confirmed by Marvell with a SATA analyzer. The Marvell port-multiplier apparently likes to see clean HOB information when accessing PMP registers. Since sata_mv uses PIO shadow register access, this doesn't happen automatically, as it might in a more purely FIS-based driver (eg. ahci). One way to fix this is to flag these commands with ATA_TFLAG_LBA48, forcing libata to write out the HOB fields with known (zero) values.

2008-02-24libata: automatically use DMADIR if drive/bridge requires itTejun Heo
Back in 2.6.17-rc2, a libata module parameter was added for atapi_dmadir. That's nice, but most SATA devices which need it will tell us about it in their IDENTIFY PACKET response, as bit-15 of word-62 of the returned data (as per ATA7, ATA8 specifications). So for those which specify it, we should automatically use the DMADIR bit. Otherwise, disc writing will fail by default on many SATA-ATAPI drives. This patch adds ATA_DFLAG_DMADIR and make ata_dev_configure() set it if atapi_dmadir is set or identify data indicates DMADIR is necessary. atapi_xlat() is converted to check ATA_DFLAG_DMADIR before setting DMADIR.

2008-02-23[NEIGH]: Fix race between neighbor lookup and table's hash_rnd update.Pavel Emelyanov
The neigh_hash_grow() may update the tbl->hash_rnd value, which is used in all tbl->hash callbacks to calculate the hashval. Two lookup routines may race with this, since they call the ->hash callback without the tbl->lock held. Since the hash_rnd is changed with this lock write-locked moving the calls to ->hash under this lock read-locked closes this gap.

2008-02-23[RTNL]: Validate hardware and broadcast address attribute for RTM_NEWLINKThomas Graf
RTM_NEWLINK allows for already existing links to be modified. For this purpose do_setlink() is called which expects address attributes with a payload length of at least dev->addr_len. This patch adds the necessary validation for the RTM_NEWLINK case. The address length for links to be created is not checked for now as the actual attribute length is used when copying the address to the netdevice structure. It might make sense to report an error if less than addr_len bytes are provided but enforcing this might break drivers trying to be smart with not transmitting all zero addresses.

2008-02-23Add memory barrier semantics to wake_up() & coLinus Torvalds
Oleg Nesterov and others have pointed out that on some architectures, the traditional sequence of set_current_state(TASK_INTERRUPTIBLE); if (CONDITION) return; schedule(); is racy wrt another CPU doing CONDITION = 1; wake_up_process(p); because while set_current_state() has a memory barrier separating setting of the TASK_INTERRUPTIBLE state from reading of the CONDITION variable, there is no such memory barrier on the wakeup side. Now, wake_up_process() does actually take a spinlock before it reads and sets the task state on the waking side, and on x86 (and many other architectures) that spinlock is in fact equivalent to a memory barrier, but that is not generally guaranteed. The write that sets CONDITION could move into the critical region protected by the runqueue spinlock. However, adding a smp_wmb() to before the spinlock should now order the writing of CONDITION wrt the lock itself, which in turn is ordered wrt the accesses within the spinlock (which includes the reading of the old state). This should thus close the race (which probably has never been seen in practice, but since smp_wmb() is a no-op on x86, it's not like this will make anything worse either on the most common architecture where the spinlock already gave the required protection).

(sorry for being offtpoic, but while experts are here...) A "typical" implementation of atomic_add_unless() can return 0 immediately after the first atomic_read() (before doing cmpxchg). In that case it doesn't provide any barrier semantics. See include/asm-ia64/atomic.h as an example. We should either change the implementation, or fix the docs.

Document huge memory/cache overhead of memory controller in Kconfig I was a little surprised that 2.6.25-rc* increased struct page for the memory controller. At least on many x86-64 machines it will not fit into a single cache line now anymore and also costs considerable amounts of RAM. At earlier review I remembered asking for a external data structure for this. It's also quite unobvious that a innocent looking Kconfig option with a single line Kconfig description has such a negative effect. This patch attempts to document these disadvantages at least so that users configuring their kernel can make a informed decision.

2008-02-23kernel-doc: fix function-pointer-parameter parsingRichard Kennedy
When running "make htmldocs" I'm seeing some non-fatal perl errors caused by trying to parse the callback function definitions in blk-core.c. The errors are "Use of uninitialized value in concatenation (.)..." in combination with: Warning(linux-2.6.25-rc2/block/blk-core.c:1877): No description found for parameter '' The function pointers are defined without a * i.e. int (drv_callback)(struct request *) The compiler is happy with them, but kernel-doc isn't. This patch teaches create_parameterlist in kernel-doc to parse this type of function pointer definition, but is it the right way to fix the problem ? The problem only seems to occur in blk-core.c. However with the patch applied, kernel-doc finds the correct parameter description for the callback in blk_end_request_callback, which is doesn't normally. I thought it would be a bit odd to change to code to use the more normal form of function pointers just to get the documentation to work, so I fixed kernel-doc instead - even though this is teaching it to understand code that might go away (The comment for blk_end_request_callback says that it should not be used and will removed at some point).
