2009-06-17rb_tree: remove redundant if()-condition in rb_erase()Wolfram Strepp1-4/+4
Furthermore, notice that the initial checks: if (!node->rb_left) child = node->rb_right; else if (!node->rb_right) child = node->rb_left; else { ... } guarantee that old->rb_right is set in the final else branch, therefore we can omit checking that again.

2009-06-17rb_tree: make clear distinction between two different cases in rb_erase()Wolfram Strepp1-4/+4
There are two cases when a node, having 2 childs, is erased: 'normal case': the successor is not the right-hand-child of the node to be erased 'special case': the successor is the right-hand child of the node to be erased Here some ascii-art, with following symbols (referring to the code): O: node to be deleted N: the successor of O P: parent of N C: child of N L: some other node normal case: O N / \ / \ / \ / \ L \ L \ / \ P ----> / \ P / \ / \ / / N C \ / \ \ C / \ special case: O|P N / \ / \ / \ / \ L \ L \ / \ N ----> / C \ / \ \ C / \ Notice that for the special case we don't have to reconnect C to N.

2009-06-17lib/genalloc.c: remove unmatched write_lock() in gen_pool_destroyZygo Blaxell1-1/+0
There is a call to write_lock() in gen_pool_destroy which is not balanced by any corresponding write_unlock(). This causes problems with preemption because the preemption-disable counter is incremented in the write_lock() call, but never decremented by any call to write_unlock(). This bug is gen_pool_destroy, and one of them is non-x86 arch-specific code.

2009-06-17console: make blank timeout value a boot optionDaniel Mack2-6/+11
The console blank timer is currently hardcoded to 10*60 seconds which might be annoying on systems with no input devices attached to wake up the console again. Especially during development, disabling the screen saver can be handy - for example when debugging the root fs mount mechanism or other scenarios where no userspace program could be started to do that at runtime from userspace. This patch defines a core_param for the variable in charge which allows users to entirely disable the blank feature at boot time by setting it 0. The value can still be overwritten at runtime using the standard ioctl call - this just allows to conditionally change the default.

Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file.

Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

2009-06-17slow-work: use round_jiffies() for thread pool's cull and OOM timersChris Peterson1-9/+14
Round the slow work queue's cull and OOM timeouts to whole second boundary with round_jiffies(). The slow work queue uses a pair of timers to cull idle threads and, after OOM, to delay new thread creation. This patch also extracts the mod_timer() logic for the cull timer into a separate helper function. By rounding non-time-critical timers such as these to whole seconds, they will be batched up to fire at the same time rather than being spread out. This allows the CPU wake up less, which saves power.

2009-06-17remove put_cpu_no_resched()Thomas Gleixner3-5/+4
put_cpu_no_resched() is an optimization of put_cpu() which unfortunately can cause high latencies. The nfs iostats code uses put_cpu_no_resched() in a code sequence where a reschedule request caused by an interrupt between the get_cpu() and the put_cpu_no_resched() can delay the reschedule for at least HZ. The other users of put_cpu_no_resched() optimize correctly in interrupt code, but there is no real harm in using the put_cpu() function which is an alias for preempt_enable(). The extra check of the preemmpt count is not as critical as the potential source of missing a reschedule. Debugged in the preempt-rt tree and verified in mainline.

2009-06-17poll: avoid extra wakeups in select/pollEric Dumazet2-4/+39
After introduction of keyed wakeups Davide Libenzi did on epoll, we are able to avoid spurious wakeups in poll()/select() code too. For example, typical use of poll()/select() is to wait for incoming network frames on many sockets. But TX completion for UDP/TCP frames call sock_wfree() which in turn schedules thread. When scheduled, thread does a full scan of all polled fds and can sleep again, because nothing is really available. If number of fds is large, this cause significant load. This patch makes select()/poll() aware of keyed wakeups and useless wakeups are avoided. This reduces number of context switches by about 50% on some setups, and work performed by sofirq handlers.

2009-06-17m32r: remove obsolete hw_interrupt_typeThomas Gleixner8-15/+15
The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have been kept around for migration reasons. After more than two years it's time to remove them finally. This patch cleans up one of the remaining users. When all such patches hit mainline we can remove the defines and typedefs finally. Impact: cleanup Convert the last remaining users to struct irq_chip and remove the define.
