Sabre and Psycho PCI controllers can have partial interrupt-map properties, meaning that on-board devices don't match up to any entries. Instead, they are fully specified from the beginning and we should pass them directly to the IRQ translator as-is. Also, fill in the necessary translator slots for the "graphics" and "expansion UPA" interrupts on Sabre, Psycho, and SYSIO SBUS. Increase PROMREG_MAX to 24, as seen on SUNW,ffb devices. Finally, prevent accidentally writing past the end of the of_device struct resource[] and irqs[] arrays. Spit out a log message when we ignore some entries because there are too many of them.

With this patch TX queue descriptors are not chained per default any more. The pointer to next descriptor is set only when next descriptor is prepaired for transfer. Also the mechanism of checking wether Spider is ready has been changed: it checks not for CARDOWNED flag in status of previous descriptor but for a TXDMAENABLED flag in Spider's register.

When sky2 driver gets lots of received packets at once, it can get stuck. The NAPI poll routine gets called back to keep going, but since no IRQ bits are set it doesn't make progress.

Jeff Garzik authored
Prior to this patch, the driver would do this for each port: read 8-bit PCS write 8-bit PCS read 8-bit PCS write 8-bit PCS In the field, flaky behavior has been observed related to this register. In particular, these overzealous register writes can cause misdetection problems. Update to do the following once (not once per port) at boot: read 16-bit PCS if needs changing, write 16-bit PCS And thereafter, we only perform a 'read 16-bit PCS' per port. This should eliminate all PCS writes in many cases, and be more friendly in the cases where we do need to enable ports. Signed-off-by: -

Some -mm-only material leaked into a patch destined for mainline, and I didn't notice. This was the replacement of system_utsname with utsname() that's required by the uts namespace patch. This patch reverts those changes (which are correct in -mm) so that mainline UML builds again. Signed-off-by:

This just turns off chmod() on the /proc/<pid>/ files, since there is no good reason to allow it, and had we disallowed it originally, the nasty /proc race exploit wouldn't have been possible. The other patches already fixed the problem chmod() could cause, so this is really just some final mop-up.. This particular version is based off a patch by Eugene and Marcel which had much better naming than my original equivalent one. Signed-off-by:

set_wmb should not be used in the kernel because it just confuses the code more and has no benefit. Since it is not currently used in the kernel this patch removes it so that new code does not include it. All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway. Hasn't been tested on any archs but x86 and x86_64 (and only compiled tested) Signed-off-by:Steven Rostedt <rostedt@goodmis.org> Signed-off-by:

In send_cpu_listeners(), which is called on the exit path, a down_write() was protecting operations like skb_clone() and genlmsg_unicast() that do GFP_KERNEL allocations. If the oom-killer decides to kill tasks to satisfy the allocations,the exit of those tasks could block on the same semphore. The down_write() was only needed to allow removal of invalid listeners from the listener list. The patch converts the down_write to a down_read and defers the removal to a separate critical region. This ensures that even if the oom-killer is called, no other task's exit is blocked as it can still acquire another down_read. Thanks to Andrew Morton & Herbert Xu for pointing out the oom related pitfalls, and to Chandra Seetharaman for suggesting this fix instead of using something more complex like RCU. Signed-off-by:

On systems with a large number of cpus, with even a modest rate of tasks exiting per cpu, the volume of taskstats data sent on thread exit can overflow a userspace listener's buffers. One approach to avoiding overflow is to allow listeners to get data for a limited and specific set of cpus. By scaling the number of listeners and/or the cpus they monitor, userspace can handle the statistical data overload more gracefully. In this patch, each listener registers to listen to a specific set of cpus by specifying a cpumask. The interest is recorded per-cpu. When a task exits on a cpu, its taskstats data is unicast to each listener interested in that cpu. Thanks to Andrew Morton for pointing out the various scalability and general concerns of previous attempts and for suggesting this design. [akpm@osdl.org: build fix] Signed-off-by:

Don't send taskstats (per-pid or per-tgid) on thread exit when no one is listening for such data. Currently the taskstats interface allocates a structure, fills it in and calls netlink to send out per-pid and per-tgid stats regardless of whether a userspace listener for the data exists (netlink layer would check for that and avoid the multicast). As a result of this patch, the check for the no-listener case is performed early, avoiding the redundant allocation and filling up of the taskstats structures. Signed-off-by:

Send per-tgid data only once during exit of a thread group instead of once with each member thread exit. Currently, when a thread exits, besides its per-tid data, the per-tgid data of its thread group is also sent out, if its thread group is non-empty. The per-tgid data sent consists of the sum of per-tid stats for all *remaining* threads of the thread group. This patch modifies this sending in two ways: - the per-tgid data is sent only when the last thread of a thread group exits. This cuts down heavily on the overhead of sending/receiving per-tgid data, especially when other exploiters of the taskstats interface aren't interested in per-tgid stats - the semantics of the per-tgid data sent are changed. Instead of being the sum of per-tid data for remaining threads, the value now sent is the true total accumalated statistics for all threads that are/were part of the thread group. The patch also addresses a minor issue where failure of one accounting subsystem to fill in the taskstats structure was causing the send of taskstats to not be sent at all. The patch has been tested for stability and run cerberus for over 4 hours on an SMP. [akpm@osdl.org: bugfixes] Signed-off-by:

Export I/O delays seen by a task through /proc/<tgid>/stats for use in top etc. Note that delays for I/O done for swapping in pages (swapin I/O) is clubbed together with all other I/O here (this is not the case in the netlink interface where the swapin I/O is kept distinct) [akpm@osdl.org: printk warning fix] Signed-off-by:

Shailabh Nagar authored
Create a "taskstats" interface based on generic netlink (NETLINK_GENERIC family), for getting statistics of tasks and thread groups during their lifetime and when they exit. The interface is intended for use by multiple accounting packages though it is being created in the context of delay accounting. This patch creates the interface without populating the fields of the data that is sent to the user in response to a command or upon the exit of a task. Each accounting package interested in using taskstats has to provide an additional patch to add its stats to the common structure. [akpm@osdl.org: cleanups, Kconfig fix] Signed-off-by:
