The following patch fixes a bug in the SGI Altix tioce_reserve_m32() code. The bug was that we could walking past the end of the CE ASIC 32/40bit PMU ATE Buffer, resulting in a PIO Reply Error. Signed-off-by:

In SLES10 (2.6.16) crash dumping (in my experience, LKCD) is unable to capture the second page of the 2-page task/stack allocation. This is particularly troublesome for dump analysis, as the stack traceback cannot be done. (A similar convention is probably needed throughout the kernel to make kernel multi-page allocations detectable for dumping) Multi-page kernel allocations are represented by the single page structure associated with the first page of the allocation. The page structures associated with the other pages are unintialized. If the dumper is selecting only kernel pages it has no way to identify any but the first page of the allocation. The fix is to make the task/stack allocation a compound page. Signed-off-by:

MPI programs using certain debug options have a long startup time. This was traced to a "vmalloc/vfree" in the code that reads /proc/sgi_sn/sn_topology. On large systems, vfree requires an IPI to all cpus to do TLB purging. Replace the vmalloc/vfree with kmalloc/kfree. Although the size of the structure being allocated is unknown, it will not not exceed 96 bytes. Signed-off-by:

SERIAL_SGI_IOC4 and BLK_DEV_SGIIOC4 depend upon SGI_IOC4, and SERIAL_SGI_IOC3 depends upon SGI_IOC3. Currently the definitions are out of order in the config sequence. Fix by including drivers/sn/Kconfig immediately after SGI_SN, upon which SGI_IOC4 and SGI_IOC3 depend. Signed-off-by:

RECLAIM_DISTANCE is checked on bootup against the SLIT table distances. Zone reclaim is important for system that have higher latencies but not for systems that have multiple nodes on one motherboard and therefore low latencies. We found that on motherboard latencies are typically 1 to 1.4 of local memory access speed whereas multinode systems which benefit from zone reclaim have usually more than 1.5 times the latency of a local access. Set the reclaim distance for IA64 to 1.5 times. Signed-off-by:

AMD K7/K8 CPUs only save/restore the FOP/FIP/FDP x87 registers in FXSAVE when an exception is pending. This means the value leak through context switches and allow processes to observe some x87 instruction state of other processes. This was actually documented by AMD, but nobody recognized it as being different from Intel before. The fix first adds an optimization: instead of unconditionally calling FNCLEX after each FXSAVE test if ES is pending and skip it when not needed. Then do a x87 load from a kernel variable to clear FOP/FIP/FDP. This means other processes always will only see a constant value defined by the kernel in their FP state. I took some pain to make sure to chose a variable that's already in L1 during context switch to make the overhead of this low. Also alternative() is used to patch away the new code on CPUs who don't need it. Patch for both i386/x86-64. The problem was discovered originally by Jan Beulich. Richard Brunner provided the basic code for the workarounds, with contribution from Jan. This is CVE-2006-1056 Cc: richard.brunner@amd.com Cc: jbeulich@novell.com Signed-off-by:

Update the schedule for the removal of drivers depending on OBSOLETE_OSS_DRIVER as follows: - adjust OBSOLETE_OSS_DRIVER dependencie - from the release of 2.6.16 till the release of 2.6.17: approx. two months for users to report problems with the ALSA drivers for the same hardware - after the release of 2.6.17 (and before 2.6.18): remove the subset of drivers marked at OBSOLETE_OSS_DRIVER without known regressions in the ALSA drivers for the same hardware Additionally, correct some OBSOLETE_OSS_DRIVER dependencies.

This fixes a hang in mpu401_uart.c that can occur when the mpu401 interface is non-existent or otherwise doesn't respond to commands but we issue IO anyway. snd_mpu401_uart_cmd now returns an error code that is passed up the stack so that an open() will fail immediately in such cases. Eventually discovered after wine/cxoffice would constantly cause hard lockups on my desktop immediately after loading (emulating Windows too well). Turned out that I'd recently moved my sound cards around and using /dev/sequencer now talks to a sound card with a broken MPU. This second version changes -EFAULT to -EIO and frees open resources on error too. Test booted and seems to work ok. Signed-off-by:

Fix for bug #6395: Fail to resume on Tecra M2 with ADM1032 and Intel 82801DBM The BIOS of the Tecra M2 doesn't like it when it has to reboot or resume after the i2c-i801 driver has left the SMBus in PEC mode. The most simple fix is to clear the PEC bit after after every transaction. That's what this driver was doing up to 2.6.15 (inclusive). Thanks to Daniele Gaffuri for the very good report.

On the MSI-K8T-NEO2 FIR ( Athlon-64, Socket 939 with VIA-K8T800- Chipset and onboard Sound,... ) the BIOS lets you choose "DISABLED" or "AUTO" for the On-Board Sound Device. If you add another PCI-Sound-Card the BIOS disables the on-board device. So far I have a Quirk, that does set the correspondent BIT in the PCI-registers to enable the soundcard. But how to ensure that the code is executed ONLY on excactly this kind of boards (not any other with similar Chipset)? Cc: Jaroslav Kysela <perex@suse.cz> Acked-by:

[PATCH] cs5535_gpio.c: call cdev_del() during module_exit to unmap kobject references and other cleanups During module unloading, cdev_del() must be called to unmap cdev related kobject references and other cleanups(such as inode->i_cdev being set to NULL) which prevents the OOPS upon subsequent loading, usage and unloading of modules(as seen in the mail thread http://marc.theaimsgroup.com/?l=linux-kernel&m=114533640609018&w=2).

In cases where a struct kretprobe's *_handler fields are non-NULL, it is possible to cause a system crash, due to the possibility of calls ending up in zombie functions. Documentation clearly states that unused *_handlers should be set to NULL, but kprobe users sometimes fail to do so. Fix it by setting the non-relevant fields of the struct kretprobe to NULL.
