The chps[] array in struct channel_subsystem is one too short; therefore the code doesn't realize the chpid ff is already known. When several devices on chpid ff become available, the message "new_channel_path: could not register ff" is displayed for every device but the first one. Signed-off-by:

finish_arch_switch needs to update the user cpu time as well, not just the system cpu time. Otherwise the partial user cpu time of a process that is stored in the lowcore will be (mis-)accounted to the next process. Signed-off-by:

The show_task function walks the kernel stack backchain of processes assuming that the processes are not running. Since this assumption is not correct walking the backchain can lead to an addressing exception and therefore to a kernel hang. So prevent the kernel hang (you still get incorrect results) verity that all read accesses are within the bounds of the kernel stack before performing them. Signed-off-by:

Provide ECB and CBC encrypt / decrypt functions to crypto API to speed up our hardware accelerated DES implementation. This new functions allow the crypto API to call ECB / CBC directly with large blocks in difference to the old functions that were calles with algorithm block size (8 bytes for DES). This is up to factor 10 faster than our old hardware implementation :) Signed-off-by:

Move the HOTPLUG_CPU option under "Processor type" instead of under "Bus options". This makes it the same for i386 as most other processor types (arm, ia64, parisc, ppc, s390, & x86_64; but not for powerpc). Besides, it takes me too long to find it under Bus options. I can't be the only person who has trouble finding it. Signed-off-by:

Add support for the PowerPC MPC83xx watchdog. The MPC83xx has a simple watchdog that once enabled it can not be stopped, has some simple timeout range selection, and the ability to either reset the processor or take a machine check. Signed-off-by:

Anything that writes into a tmpfs filesystem is liable to disproportionately decrease the available memory on a particular node. Since there's no telling what sort of application (e.g. dd/cp/cat) might be dropping large files there, this lets the admin choose the appropriate default behavior for their site's situation. Introduce a tmpfs mount option which allows specifying a memory policy and a second option to specify the nodelist for that policy. With the default policy, tmpfs will behave as it does today. This patch adds support for preferred, bind, and interleave policies. The default policy will cause pages to be added to tmpfs files on the node which is doing the writing. Some jobs expect a single process to create and manage the tmpfs files. This results in a node which has a significantly reduced number of free pages. With this patch, the administrator can specify the policy and nodes for that policy where they would prefer allocations. This patch was originally written by Brent Casavant and Hugh Dickins. I added support for the bind and preferred policies and the mpol_nodelist mount option. Signed-off-by:

This is a 2.6 patch that adds support for the watchdog timer built into the EPX-C3 single board computer manufactured by Winsystems, Inc. Driver details: This is for x86 only. This watchdog is pretty basic and simple. It is only configurable via jumpers on the SBC, and it only has either a 1.5s or 200s interval. The watchdog can either be auto-configured to start as soon as the machine powers up (bad idea for the 1.5s interval!) or it can be enabled and disabled by writing to io port 0x1ee. Petting the watchdog involves writing any value to io port 0x1ef. The only unfortunate thing about this watchdog (and it is not at all uncommmon in watchdogs that linux supports) is that it is not a PCI or ISA-PNP device and as such it isn't at all probeable. Either the watchdog exists as 2 bytes at 0x1ee, or it doesn't. Thus, using this driver on a machine that doesn't have that watchdog can potentially hang/crash the system, etc. So only use this driver if you in fact are on a Winsystems EPX-C3 SBC. Anyway this driver fits into the already-existing watchdog framework quite nicely and I already tested it on my EPX-C3 and it works like a charm. Signed-off-by:

Add a new SCHED_BATCH (3) scheduling policy: such tasks are presumed CPU-intensive, and will acquire a constant +5 priority level penalty. Such policy is nice for workloads that are non-interactive, but which do not want to give up their nice levels. The policy is also useful for workloads that want a deterministic scheduling policy without interactivity causing extra preemptions (between that workload's tasks). Signed-off-by:

Add driver support for a 2 port PCI IOC3-based serial card on Altix boxes: This is a re-submission. On the original submission I was asked to organize the code so that the MIPS ioc3 ethernet and serial parts could be used with this driver. Stanislaw Skowronek was kind enough to provide the shim layer for this - thanks Stanislaw. This patch includes the shim layer and the Altix PCI ioc3 serial driver. The MIPS merged ioc3 ethernet and serial support is forthcoming. Signed-off-by:

Fixed the refcounting on failure exits in sys_mq_open() and cleaned the logics up. Rules are actually pretty simple - dentry_open() expects vfsmount and dentry to be pinned down and it either transfers them into created struct file or drops them. Old code had been very confused in that area - if dentry_open() had failed either in do_open() or do_create(), we ended up dentry and mqueue_mnt dropped twice, once by dentry_open() cleanup and then by sys_mq_open(). Fix consists of making the rules for do_create() and do_open() same as for dentry_open() and updating the sys_mq_open() accordingly; that actually leads to more straightforward code and less work on normal path.

Given the semantic changes in both the device-model and fc-transport APIs, the driver's handling of port-type RSCNs via a series of ADISCs and PLOGIs can cause series of badness ranging from unexpectedly device loss to devices not being discovered. In the interim, disable (via a module-parameter) this feature and allow RSCN management to continue to occur within the driver's DPC thread. Signed-off-by:
