2005-10-17[IB] mthca: Better limit checking and reportingJack Morgenstein
Check the sizes of CQs, QPs and SRQs when creating objects, and fail instead of creating too-big queues. Also return real limits instead of just plausible-sounding values from mthca_query_device().

2005-10-17[IB] Fix leak on MAD initialization failureRoland Dreier
There is a bug in ib_mad_init_device(): if ib_agent_port_open() fails for a given port, then the current code doesn't call ib_mad_port_close() for that port. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-17[IB] mthca: detect SRQ overflowRoland Dreier
The hardware relies on us keeping one extra work request that never gets used in SRQs. Add checks to the SRQ work request posting functions so that they fail when someone is about to use up that extra work request, rather than when someone uses the very last work request. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-17[IB] mthca: SRQ limit reached eventsRoland Dreier
Our hardware supports generating an event when the number of receives posted to a shared receive queue (SRQ) falls below a user-specified limit. Implement mthca_modify_srq() to arm the limit, and add code to handle dispatching SRQ events when they occur. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-10-17[IB] uverbs: Fix up resource creation error pathsRoland Dreier
By waiting to add resources to our lists until after the last operation that can fail, we don't have to remove them from their lists in the error path. Also, we should hold the idr mutex until we know whether resource creation has succeed or failed, to avoid someone finding a resource in our table before we're ready.

2005-10-17[IB] uverbs: ABI-breaking fixes for userspace verbsRoland Dreier
Introduce new userspace verbs ABI version 3. This eliminates some unneeded commands, and adds support for user-created completion channels. This cleans up problems with file leaks on error paths, and also makes sure that file descriptors are always installed into the correct process. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2005-10-17Increase default RCU batching sharplyLinus Torvalds
Dipankar made RCU limit the batch size to improve latency, but that approach is unworkable: it can cause the RCU queues to grow without bounds, since the batch limiter ended up limiting the callbacks. So make the limit much higher, and start planning on instead limiting the batch size by doing RCU callbacks more often if the queue looks like it might be growing too long.

2005-10-17[PATCH] fix black/white-only svideo input in vpx3220 decoderRonald S. Bultje
Fix the fact that the svideo input will only give input in black/white in some circumstances. Reason is that in the PCI controller driver (zr36067), after setting input, we reset norm, which overwrites the input register with the default. This patch makes it always set the correct value for the input when changing norm. Signed-off-by: Ronald S.

2005-10-17[PATCH] fix vpx3220 offset issue in SECAMRonald S. Bultje
Fix bug #5404 in kernel bugzilla. It basically updates the vpx3220 initialization tables with some newer values that we've had in CVS for a while (and that, for some reason, never ended up in the kernel... must've gotten lost). Those fix a ~16 pixels noise at the top of the picture in at least SECAM, although (now that I think about it) PAL was probably affected, also. Signed-off-by: Ronald S.

2005-10-17[PATCH] SVGATextMode fixSamuel Thibault
Fix bug 5441. I didn't know about messy programs like svgatextmode... Couldn't this be integrated in some linux/drivers/video/console/svgacon.c ?... So because of the existence of the svgatextmode program, the kernel is not supposed to touch to CRT_OVERFLOW/SYNC_END/DISP/DISP_END/OFFSET ? Disabling the check in vgacon_resize() might help indeed, but I'm really not sure whether it will work for any chipset: in my patch, CRT registers are set at each console switch, since stty rows/cols apply to consoles separately... The attached solution is to keep the test, but if it fails, we assume that the caller knows what it does (i.e. it is svgatextmode) and then disable any further call to vgacon_doresize. Svgatextmode is usually used to _expand_ the display, not to shrink it. And it is harmless in the case of a too big stty rows/cols: the display will just be cropped. I tested it on my laptop, and it works fine with svgatextmode. A better solution would be that svgatextmode explicitely tells the kernel not to care about video timing, but for this an interface needs be defined and svgatextmode be patched.

2005-10-17[PATCH] list: add missing rcu_dereference on first elementHerbert Xu
It seems that all the list_*_rcu primitives are missing a memory barrier on the very first dereference. For example, #define list_for_each_rcu(pos, head) \ for (pos = (head)->next; prefetch(pos->next), pos != (head); \ pos = rcu_dereference(pos->next)) It will go something like: pos = (head)->next prefetch(pos->next) pos != (head) do stuff We're missing a barrier here. pos = rcu_dereference(pos->next) fetch pos->next barrier given by rcu_dereference(pos->next) store pos Without the missing barrier, the pos->next value may turn out to be stale. In fact, if "do stuff" were also dereferencing pos and relying on list_for_each_rcu to provide the barrier then it may also break. So here is a patch to make sure that we have a barrier for the first element in the list. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Acked-by: "Paul E.

2005-10-16Fix memory ordering bug in page reclaimLinus Torvalds
As noticed by Nick Piggin, we need to make sure that we check the page count before we check for PageDirty, since the dirty check is only valid if the count implies that we're the only possible ones holding the page. We always did do this, but the code needs a read-memory-barrier to make sure that the orderign is also honored by the CPU. (The writer side is ordered due to the atomic decrement and test on the page count, see the discussion on linux-kernel) Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-10-16[PATCH]: highest_possible_processor_id() has to be a macroAl Viro
... otherwise, things like alpha and sparc64 break and break badly. They define cpu_possible_map to something else in smp.h *AFTER* having included cpumask.h. If that puppy is a macro, expansion will happen at the actual caller, when we'd already seen #define cpu_possible_map ... and we will get the right thing used. As an inline helper it will be tokenized before we get to that define and that's it; no matter what we define later, it won't affect anything. We get modules with dependency on cpu_possible_map instead of the right symbol (phys_cpu_present_map in case of sparc64), or outright link errors if they are built-in.

2005-10-14[PATCH] wireless/airo: Build fixMatteo Croce
The aironet PCI driver has a build dependency on ISA that prevent the driver to compile on systems that doesn't support ISA, like x86_64. The driver really doesn't depend on ISA, it does some ISA stuff in the initialization code, since the driver supports both ISA and PCI cards. So the driver should depend on ISA_DMA_API to build on all systems, and this will not hurt PCI at all.
