2007-09-25ACPI: hpet: ACPI Error (utglobal-0126): Unknown exception code: 0xFFFFFFF0Zhao Yakui
If hpet has been initialized before registering hpet driver, the callback function of hpet_resources will return the status code of -EBUSY, which is not defined in the ACPI exception table. So when ACPI checks the status code of callback function, it will report the unknown exception code. So the status code in ACPI is used instead of the generic error code in the ACPI callback function of hpet_resources. For example: -EBUSY is replaced by AE_ALREADY_EXISTS -EINVAL is replaced by AE_NO_MEMORY http://bugzilla.kernel.org/show_bug.cgi?id=8630 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2007-09-24raid5: fix 2 bugs in ops_complete_biofillDan Williams
1/ ops_complete_biofill tried to avoid calling handle_stripe since all the state necessary to return read completions is available. However the process of determining whether more read requests are pending requires locking the stripe (to block add_stripe_bio from updating dev->toead). ops_complete_biofill can run in tasklet context, so rather than upgrading all the stripe locks from spin_lock to spin_lock_bh this patch just unconditionally reschedules handle_stripe after completing the read request. 2/ ops_complete_biofill needlessly qualified processing R5_Wantfill with dev->toread. The result being that the 'biofill' pending bit is cleared before handling the pending read-completions on dev->read. R5_Wantfill can be unconditionally handled because the 'biofill' pending bit prevents new R5_Wantfill requests from being seen by ops_run_biofill and ops_complete_biofill.

2007-09-23IB/mlx4: Fix data corruption triggered by wrong headroom marking orderJack Morgenstein
This is an addendum to commit 0e6e7416 ("IB/mlx4: Handle new FW requirement for send request prefetching"). We also need to handle prefetch marking properly for S/G segments, or else the HCA may end up processing S/G segments that are not fully written and end up sending the wrong data. This can actually cause data corruption in practice, especially on systems with relatively slow CPUs (where the HCA is more likely to prefetch while the CPU is in the middle of writing a work request into memory). We write S/G segments in reverse order into the WQE, in order to guarantee that the first dword of all cachelines containing S/G segments is written last (overwriting the headroom invalidation pattern). The entire cacheline will thus contain valid data when the invalidation pattern is overwritten.

2007-09-22ACPI: disable lower idle C-states across suspend/resumeThomas Gleixner
device_suspend() calls ACPI suspend functions, which seems to have undesired side effects on lower idle C-states. It took me some time to realize that especially the VAIO BIOSes (both Andrews jinxed UP and my elfstruck SMP one) show this effect. I'm quite sure that other bug reports against suspend/resume about turning the system into a brick have the same root cause. After fishing in the dark for quite some time, I realized that removing the ACPI processor module before suspend (this removes the lower C-state functionality) made the problem disappear. Interestingly enough the propability of having a bricked box is influenced by various factors (interrupts, size of the ram image, ...). Even adding a bunch of printks in the wrong places made the problem go away. The previous periodic tick implementation simply pampered over the problem, which explains why the dyntick / clockevents changes made this more prominent. We avoid complex functionality during the boot process and we have to do the same during suspend/resume. It is a similar scenario and equaly fragile. Add suspend / resume functions to the ACPI processor code and disable the lower idle C-states across suspend/resume. Fall back to the default idle implementation (halt) instead.

2007-09-22[SCSI] scsi_transport_spi: fix domain validation failure from incorrect ↵James Bottomley
width setting Domain Validation in the SPI transport class is failing on boxes with damaged cables (and failing to the extent that the box hangs). The problem is that the first test it does is a cable integrity test for wide transfers and if this fails, it turns the wide bit off. The problem is that the next set of tests it does turns wide back on again, with the result that it runs through the entirety of DV with a known bad setting and then hangs the system. The attached patch fixes the problem by physically nailing the wide setting to what it deduces it should be for the whole of Domain Validation.

2007-09-22[POWERPC] adbhid: Enable KEY_FN key reportingAristeu Rozanski
When a Fn key is used in combination with another key in ADB keyboards it will generate a Fn event and then a second event that can be a different key than pressed (Fn + F1 for instance can generate Fn + brightness down if it's configured like that). This enables the reporting of the Fn key to the input system. As Fn is a dead key for most purposes, it's useful to report it so applications can make use of it. One example is apple_mouse (https://jake.ruivo.org/uinputd/trunk/apple_mouse/) that emulates the second and third keys using a combination of keyboard keys and the mouse button. Other applications may use the KEY_FN as a modifier as well. I've been updating and using this patch for months without problems.

This adds the option for the pmac_zilog driver to use the major/minor numbers recently allocated specifically for it (/dev/ttyPZn) instead of the /dev/ttySn numbers. The advantage of doing this is that it allows the pmac_zilog and 8250 drivers to coexist. The disadvantage of doing this is that it is a user-visible ABI change and it will break existing working setups on powermacs, and could be confusing to users.

2007-09-20[PPP] L2TP: Fix skb handling in pppol2tp_xmitHerbert Xu
This patch makes pppol2tp_xmit call skb_cow_head so that we don't modify cloned skb data. It also gets rid of skb2 we only need to preserve the original skb for congestion notification, which is only applicable for ppp_async and ppp_sync. The other semantic change made here is the removal of socket accounting for data tranmitted out of pppol2tp_xmit. The original code leaked any existing socket skb accounting. We could fix this by dropping the original skb owner. However, this is undesirable as the packet has not physically left the host yet. In fact, all other tunnels in the kernel do not account skb's passing through to their own socket. In partciular, ESP over UDP does not do so and it is the closest tunnel type to PPPoL2TP. So this patch simply removes the socket accounting in pppol2tp_xmit. The accounting still applies to control packets of course. I've also added a reminder that the outgoing checksum here doesn't work. I suppose existing deployments don't actually enable checksums.

2007-09-20[POWERPC] Cleanups for physmap_of.c (v2)David Gibson
This patch includes a whole batch of smallish cleanups for drivers/mtd/physmap_of.c. - A bunch of uneeded #includes are removed - We switch to the modern linux/of.h etc. in place of asm/prom.h - Use some helper macros to avoid some ugly inline #ifdefs - A few lines of unreachable code are removed - A number of indentation / line-wrapping fixes - More consistent use of kernel idioms such as if (!p) instead of if (p == NULL) - Clarify some printk()s and other informative strings. - parse_obsolete_partitions() now returns 0 if no partition information is found, instead of returning -ENOENT which the caller had to handle specially. - (the big one) Despite the name, this driver really has nothing to do with drivers/mtd/physmap.c. The fact that the flash chips must be physically direct mapped is a constrant, but doesn't really say anything about the actual purpose of this driver, which is to instantiate MTD devices based on information from the device tree. Therefore the physmap name is replaced everywhere within the file with "of_flash". The file itself and the Kconfig option is not renamed for now (so that the diff is actually a diff).
