2010-10-27epoll: make epoll_wait() use the hrtimer range featureShawn Bohrer3-17/+22
This make epoll use hrtimers for the timeout value which prevents epoll_wait() from timing out up to a millisecond early. This mirrors the behavior of select() and poll().

The conversion from cputime to the taskstats values uses the cputime_to_msecs primitive which effectively limits the granularity to milliseconds. Add the cputime_to_usecs primitive for architectures that have better, more precise CPU time values. Remove cputime_to_msecs primitive because there are no more users left.

2010-10-27delayacct: align to 8 byte boundary on 64-bit systemsJeff Mahoney1-1/+7
prepare_reply() sets up an skb for the response. The payload contains: +--------------------------------+ | genlmsghdr - 4 bytes | +--------------------------------+ | NLA header - 4 bytes | /* Aggregate header */ +-+------------------------------+ | | NLA header - 4 bytes | /* PID header */ | +------------------------------+ | | pid/tgid - 4 bytes | | +------------------------------+ | | NLA header - 4 bytes | /* stats header */ | + -----------------------------+ <- oops. aligned on 4 byte boundary | | struct taskstats - 328 bytes | +-+------------------------------+ The start of the taskstats struct must be 8 byte aligned on IA64 (and other systems with 8 byte alignment rules for 64-bit types) or runtime alignment warnings will be issued. This patch pads the pid/tgid field out to sizeof(long), which forces the alignment of taskstats. The getdelays userspace code is ok with this since it assumes 32-bit pid/tgid and then honors that header's length field. An array is used to avoid exposing kernel memory contents to userspace in the response.

2010-10-27delay-accounting: reimplement -c for getdelays.c to report information on a ↵Mel Gorman1-2/+36
target command Task delay-accounting was identified as one means of determining how long a process spends in congestion_wait() without adding new statistics. For example, if the workload should not be doing IO, delay-accounting could reveal how long it was spending in unexpected IO or delays. Unfortunately, on closer examination it was clear that getdelays does not act as documented. Commit a3baf649 ("per-task-delay-accounting: documentation") added Documentation/accounting/getdelays.c with a -c switch that was documented to fork/exec a child and report statistics on it but for reasons that are unclear to me, commit 9e06d3f9 deleted support for this switch but did not update the documentation. It might be an oversight or it might be because the control flow of the program meant that accounting information would be printed once early in the lifetime of the program making it of limited use. This patch reimplements -c for getdelays.c to act as documented. Unlike the original version, it waits until the command completes before printing any information on it. An example of it being used looks like $ ./getdelays -d -c find /home/mel -name mel print delayacct stats ON /home/mel /home/mel/.notes-wine/drive_c/windows/profiles/mel /home/mel/.wine/drive_c/windows/profiles/mel /home/mel/git-configs/dot.kde/share/apps/konqueror/home/mel PID 5923 CPU count real total virtual total delay total 42779 5051232096 5164722692 564207988 IO count delay total 41727 97804147758 SWAP count delay total 0 0 RECLAIM count delay total 0 0 [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Mel Gorman <mel@csn.ul.ie> Acked-by: Balbir Singh <balbir@in.ibm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Enumerator sets Component Tag (!= 0) immediately during device setup. This allows to identify the device if the redundant route exists in a RIO system.

2010-10-27synclink_gt: fix per device lockingPaul Fulghum1-13/+15
Fix a long standing bug with per device locking. Each device has an associated spinlock for synchronizing access to hardware and state information with the ISR. A single hardware card has one or more devices. Bug: Non ISR code correctly acquires and releases the per device lock. ISR incorrectly always acquires and releases the lock of the first device on the card. The decoupled and list based nature of the ISR and deferred processing interaction allowed this to work in normal operation. Exceptional events like an application forcing hardware shutdown, reset, or reconfiguration while active can trigger the bug. Fixed ISR to acquire and release the per device lock. One exception is manipulation of the GPIO card resource which is global and effectively owned by the first device of the card. Non-ISR access to GPIO resource is changed to use lock of first device on card.

This patch for SGI Altix/IA64 eliminates interval long timer holdoffs in cases where we don't start an interval timer before the expiration time. This sometimes happens when a number of interval timers on the same shub with the same interval run simultaneously.
