2011-07-21x86, perf: Make copy_from_user_nmi() a library functionRobert Richter
copy_from_user_nmi() is used in oprofile and perf. Moving it to other library functions like copy_from_user(). As this is x86 code for 32 and 64 bits, create a new file usercopy.c for unified code.

2011-07-21vfs: drop conditional inode prefetch in __do_lookup_rcuLinus Torvalds
It seems to hurt performance in real life. Yes, the inode will be used later, but the conditional doesn't seem to predict all that well (negative dentries are not uncommon) and it looks like the cost of prefetching is simply higher than depending on the cache doing the right thing. As usual. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2011-07-21FS-Cache: Fix __fscache_uncache_all_inode_pages()'s outer loopJan Beulich
The compiler, at least for ix86 and m68k, validly warns that the comparison: next <= (loff_t)-1 is always true (and it's always true also for x86-64 and probably all other arches - as long as pgoff_t isn't wider than loff_t). The intention appears to be to avoid wrapping of "next", so rather than eliminating the pointless comparison, fix the loop to indeed get exited when "next" would otherwise wrap. On m68k the following warning is observed: fs/fscache/page.c: In function '__fscache_uncache_all_inode_pages': fs/fscache/page.c:979: warning: comparison is always false due to limited range of data type Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Reported-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: David Howells <dhowells@redhat.com> Cc: Suresh Jayaraman <sjayaraman@suse.de> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: stable@kernel.org Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-07-21sched: Replace use of entity_key()Stephan Baerwolf
"entity_key()" is only used in "__enqueue_entity()" and its only function is to subtract a tasks vruntime by its groups minvruntime. Before this patch a rbtree enqueue-decision is done by comparing two tasks in the style: "if (entity_key(cfs_rq, se) < entity_key(cfs_rq, entry))" which would be "if (se->vruntime-cfs_rq->min_vruntime < entry->vruntime-cfs_rq->min_vruntime)" or (if reducing cfs_rq->min_vruntime out) "if (se->vruntime < entry->vruntime)" which is "if (entity_before(se, entry))" So we do not need "entity_key()". If "entity_before()" is inline we will also save one subtraction (only one, because "entity_key(cfs_rq, se)" was cached in "key") Signed-off-by: Stephan Baerwolf <stephan.baerwolf@tu-ilmenau.de> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/n/tip-ns12mnd2h5w8rb9agd8hnsfk@git.kernel.org Signed-off-by: Ingo Molnar <mingo@elte.hu>
2011-07-21sched: Separate group-scheduling code more clearlyJan H. Schönherr
Clean up cfs/rt runqueue initialization by moving group scheduling related code into the corresponding functions. Also, keep group scheduling as an add-on, so that things are only done additionally, i. e. remove the init_*_rq() calls from init_tg_*_entry(). (This removes a redundant initalization during sched_init()). In case of group scheduling rt_rq->highest_prio.curr is now initialized twice, but adding another #ifdef seems not worth it.

2011-07-21sched: Do not attempt to destroy uninitialized rt_bandwidthBianca Lutz
If a task group is to be created and alloc_fair_sched_group() fails, then the rt_bandwidth of the corresponding task group is not yet initialized. The caller, sched_create_group(), starts a clean up procedure which calls free_rt_sched_group() which unconditionally destroys the not yet initialized rt_bandwidth. This crashes or hangs the system in lock_hrtimer_base(): UP systems dereference a NULL pointer, while SMP systems loop endlessly on a condition that cannot become true. This patch simply avoids the destruction of rt_bandwidth when the initialization code path was not reached. (This was discovered by accident with a custom kernel modification.)

Use for_each_leaf_cfs_rq() instead of list_for_each_entry_rcu(), this achieves that load_balance_fair() only iterates those task_groups that actually have tasks on busiest, and that we iterate bottom-up, trying to move light groups before the heavier ones.

2011-07-21sched: update correct entity's runtime in check_preempt_wakeup()Paul Turner
While looking at check_preempt_wakeup() I realized that we are potentially updating the wrong entity in the fair-group scheduling case. In this case the current task's cfs_rq may not be the same as the one used for the comparison between the waking task and the existing task's vruntime. This potentially results in us using a stale vruntime in the pre-emption decision, providing a small false preference for the previous task. The effects of this are bounded since we always perform a hierarchal update on the tick.

2011-07-21ptrace: fix ptrace_signal() && STOP_DEQUEUED interactionOleg Nesterov
Simple test-case, int main(void) { int pid, status; pid = fork(); if (!pid) { pause(); assert(0); return 0x23; } assert(ptrace(PTRACE_ATTACH, pid, 0,0) == 0); assert(wait(&status) == pid); assert(WIFSTOPPED(status) && WSTOPSIG(status) == SIGSTOP); kill(pid, SIGCONT); // <--- also clears STOP_DEQUEUD assert(ptrace(PTRACE_CONT, pid, 0,0) == 0); assert(wait(&status) == pid); assert(WIFSTOPPED(status) && WSTOPSIG(status) == SIGCONT); assert(ptrace(PTRACE_CONT, pid, 0, SIGSTOP) == 0); assert(wait(&status) == pid); assert(WIFSTOPPED(status) && WSTOPSIG(status) == SIGSTOP); kill(pid, SIGKILL); return 0; } Without the patch it hangs. After the patch SIGSTOP "injected" by the tracer is not ignored and stops the tracee. Note also that if this test-case uses, say, SIGWINCH instead of SIGCONT, everything works without the patch. This can't be right, and this is confusing. The problem is that SIGSTOP (or any other sig_kernel_stop() signal) has no effect without JOBCTL_STOP_DEQUEUED. This means it is simply ignored after PTRACE_CONT unless JOBCTL_STOP_DEQUEUED was set "by accident", say it wasn't cleared after initial SIGSTOP sent by PTRACE_ATTACH. At first glance we could change ptrace_signal() to add STOP_DEQUEUED after return from ptrace_stop(), but this is not right in case when the tracer does not change the reported SIGSTOP and SIGCONT comes in between. This is even more wrong with PT_SEIZED, SIGCONT adds JOBCTL_TRAP_NOTIFY which will be "lost" during the TRAP_STOP | TRAP_NOTIFY report. So lets add STOP_DEQUEUED _before_ we report the signal. It has no effect unless sig_kernel_stop() == T after the tracer resumes us, and in the latter case the pending STOP_DEQUEUED means no SIGCONT in between, we should stop. Note also that if SIGCONT was sent, PT_SEIZED tracee will correctly report PTRACE_EVENT_STOP/SIGTRAP and thus the tracer can notice the fact SIGSTOP was cancelled. Also, move the current->ptrace check from ptrace_signal() to its caller, get_signal_to_deliver(), this looks more natural.

2011-07-21mmc: fix runtime PM with -ENOSYS suspend caseOhad Ben-Cohen
In the case where a driver returns -ENOSYS from its suspend handler to indicate that the device should be powered down over suspend, the remove routine of the driver was not being called, leading to lots of confusion during resume. The problem is that runtime PM is disabled during this process, and when we reach mmc_sdio_remove, calling the runtime PM functions here (validly) return errors, and this was causing us to skip the remove function. Fix this by ignoring the error value of pm_runtime_get_sync(), which can return valid errors. This also matches the behaviour of pci_device_remove().

Fix clock rate setting in the mxs-mmc driver. Previously, if div2 was 0 then the value for TIMING_CLOCK_RATE would have been 255 instead of 0. The limits for div1 (TIMING_CLOCK_DIVIDE) and div2 (TIMING_CLOCK_RATE+1) were also not correctly defined. Can easily be reproduced on mx23evk: default clock for high speed sdio cards is 50 MHz.

different interfaces If overlapping networks with different interfaces was added to the set, the type did not handle it properly. Example ipset create test hash:net,iface ipset add test 192.168.0.0/16,eth0 ipset add test 192.168.0.0/24,eth1 Now, if a packet was sent from 192.168.0.0/24,eth0, the type returned a match. In the patch the algorithm is fixed in order to correctly handle overlapping networks. Limitation: the same network cannot be stored with more than 64 different interfaces in a single set.

2011-07-21kexec, x86: Fix incorrect jump back address if not preserving contextHuang Ying
In kexec jump support, jump back address passed to the kexeced kernel via function calling ABI, that is, the function call return address is the jump back entry. Furthermore, jump back entry == 0 should be used to signal that the jump back or preserve context is not enabled in the original kernel. But in the current implementation the stack position used for function call return address is not cleared context preservation is disabled. The patch fixes this bug.

2011-07-21perf tools: Add automated tests for events parsingJiri Olsa
Adding builtin test for parse_events function, which is responsible for parsing/processing "-e" option for stat/top/record commands. This new test will run within the builtin test command suite (perf test). One or several tests were added for each type of event. More tests could be added easily if needed.
