The printk's that use it don't actually need to print it out at all, the rpc_task tag isn't really interesting here. Acked by Trond Myklebust.

ChangeSet@1.1338, 2003-10-09 11:23:31-07:00, ak@muc.de [PATCH] Prefetch workaround for Athlon/Opteron This is the latest iteration of the workaround for the Athlon/Opteron prefetch erratum. Sometimes the CPU would incorrectly report an exception on prefetch. This supercedes the previous dumb workaround of checking for AMD CPUs in prefetch(). That one bloated the kernel by several KB and lead to lots of unnecessary checks in hot paths. Also this one handles user space faults too, so the kernel can effectively isolte the user space from caring about this errata. Instead it handles it in the slow path of the exception handler (the check is only done when the kernel would normally trigger seg fault or crash anyways) All the serious criticisms to the previous patches have been addressed. It checks segment bases now, handles vm86 mode and avoids deadlocks when the prefetch exception happened inside mmap_sem. This includes review and fixes from Jamie Lokier and Andrew Morton. Opcode decoder based on code from Richard Brunner.

Paul McKenney convinced me that there's no *guarantee* that all archs will refuse the speculate the atomic ops above the state test, eg: CPU0 (stopref_set_state) CPU1 (stopref) atomic_set(&ack, 0); if (state == XXX) wmb(); atomic_inc(&ack); state = XXX; Certainly Alpha needs a rmb() inside stopref to guarantee it sees the same ordering. ChangeSet@1.1325, 2003-10-09 07:42:03-07:00, rusty@rustcorp.com.au [PATCH] ipt_limit fix for HZ=1000 The range that the iptables limit extension can specify depends on HZ. This means that rules which worked i386 2.4 (100 HZ) won't work on 2.6. The solution is to adjust the precision based on the HZ value (keeping the range of possible values the same). For extra geek cred, this is done by calculating a power-of-two constant below the maximum multiplication factor, which gcc then turns into a simple shift.

In both cases the error is pretty trivial. This patch is the minimum change to fix the problems. The _IOR() type problem fix in aty128fb.c depends on the fact that the size of a pointer is the same as "size_t", so we don't have to use _IOR_BAD() to keep the ioctl number the same.

ChangeSet@1.1319, 2003-10-08 18:59:24-07:00, jamie@shareable.org [PATCH] futex bug fixes This fixes two serious bugs in the futex code. One is a race condition which results in list corruption when FUTEX_REQUEUE is used. It is due to the split locks change introduced in 2.6.0-test6, and oopses when triggered. The other is a security hole. A program can use FUTEX_FD to create futexes on mms or inodes which don't reference them, and when those structures are reused by a different mm or inode, the addresses match. The effect is that a malicious or flawed program can steal wakeups from completely unrelated tasks, causing them to block (or worse if they are counting on the token passing property). These are the specific changes: 1. Each futex_q retains a reference to its key mm or inode. 2. The condition for a futex_q to indicate that it's woken can usually be interrogated lock-free. 3. futex_wait calls the hash function once instead of three times, and usually takes the per-bucket lock once too. 4. When a futex is woken, the per-bucket lock is not usually taken, so that's one less cache line transfer during heavy SMP futex use. 5. The wait condition and barriers in futex_wait are simpler. 5. FUTEX_REQUEUE is fixed. The per-bucket lock juggling is done in such a way that there are no race conditions against the tests for whether a futex is woken. This patch is an combination of patches previously sent to the list. An equivalent patch has been in Andrew Morton's tree for a while, with no failure reports. Also I have been running it on my own SMP box for a while. Conversely, we have received an oops report for the 2.6.0-test6 code, so the fix is needed. ChangeSet@1.1318, 2003-10-08 18:59:16-07:00, jamie@shareable.org [PATCH] set sigio target to current->pid and only if not already set 1. send_sigio() sends to a specific thread, _not_ a process. (It can also send to a process group, but that's not relevant here). This is useful, and should stay as it is. Therefore it makes _no sense_ to call f_setown() with current->tgid. Presently the kernel is inconsistent about it, with some places using current->pid and some others using current->tgid. This patch changes f_setown() calls to use current->pid. 2. In some places, f_setown() is called not at the user's direct request, but as a side effect of another function. Specifically: dnotify and file leases. It is good to allow a program the flexibility to specify a different pid than the default, using F_SETOWN. Presently they can do this after the dnotify or lease call, but there is a small time window when it will be temporarily set to current->tgid (which as pointed out above, is not always right). The window is avoidable if the program can use F_SETOWN prior to the dnotify or lease call. This is exactly what the "force" argument to f_setown() is for, and this patch changes it to zero in those callers. This change is not likely to affect any existing programs.

This brings us closer to working out of the box on the now popular VIA and NVidia Nforce3 based Athlon64 and Opteron boards. To be really good we would need more ACPI changes (still waiting for that to be all merged through the usual channels). With this we mostly work with acpi=off at least. Also it syncs us up with bugfixes done in 2.4. - Disable IO-APIC by default on non SMP VIA/NVidia boards. This is a bit of a hack, but needed to work around ACPI bugs. Can be overwriten with "apic". - Add acpi=ht, meaning run ACPI boot setup, but do not enable the interpreter.
