This patch implements VIRT_CPU_ACCOUNTING for ia64, which enable us to use more accurate cpu time accounting. The VIRT_CPU_ACCOUNTING is an item of kernel config, which s390 and powerpc arch have. By turning this config on, these archs change the mechanism of cpu time accounting from tick-sampling based one to state-transition based one. The state-transition based accounting is done by checking time (cycle counter in processor) at every state-transition point, such as entrance/exit of kernel, interrupt, softirq etc. The difference between point to point is the actual time consumed during in the state. There is no doubt about that this value is more accurate than that of tick-sampling based accounting.

On many chipsets, the checks for DPLL enable or VGA mode will prevent the pipeconf regs from being restored, which could result in a blank display or X failing to come back after resume.

Commit efcd9971 ("IPoIB/cm: Factor out ipoib_cm_free_rx_reap_list()") introduced a bug in ipoib_cm_dev_stop() when the receive drain times out. In that case, the function moves all the pending rx stuff into a private list but then calls ipoib_cm_free_rx_reap_list(), which handles a different list. Fix this by moving everything to the rx_reap_list that will actually get freed up. This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=906>.

由 Linus Torvalds 提交于
This reverts commit 1f84260c, which is suspected to be the reason for some very occasional and hard-to-trigger crashes that usually look related to memory allocation (mostly reported in networking, but since that's generally the most common source of shortlived allocations - and allocations in interrupt contexts - that in itself is not a big clue). See for example http://bugzilla.kernel.org/show_bug.cgi?id=9973 http://lkml.org/lkml/2008/2/19/278 etc. One promising suspicion for what the root cause of bug is (which also explains why it's so hard to trigger in practice) came from Eric Dumazet: "I wonder how SLUB_FASTPATH is supposed to work, since it is affected by a classical ABA problem of lockless algo. cmpxchg_local(&c->freelist, object, object[c->offset]) can succeed, while an interrupt came (on this cpu), and several allocations were done, and one free was performed at the end of this interruption, so 'object' was recycled. c->freelist can then contain the previous value (object), but object[c->offset] was changed by IRQ. We then put back in freelist an already allocated object." but another reason for the revert is simply that everybody agrees that this code was the main suspect just by virtue of the pattern of oopses.
