2009-06-24tracing: Reset iterator in t_start()Li Zefan
The iterator is m->private, but it's not reset to trace_types in t_start(). If the output is larger than PAGE_SIZE and t_start() is called the 2nd time, things will go wrong.

2009-06-24tracing/events: Don't increment @pos in s_start()Li Zefan
While testing syscall tracepoints posted by Jason, I found 3 entries were missing when reading available_events. The output size of available_events is < 4 pages, which means we lost 1 entry per page. The cause is, it's wrong to increment @pos in s_start(). Actually there's another bug here -- reading avaiable_events/set_events can race with module unload: # cat available_events | s_start() | s_stop() | | # rmmod foo.ko s_start() | call = list_entry(m->private) | @call might be freed and accessing it will lead to crash.

2009-06-24perf_counter, x86: Set global control MSR correctlyYong Wang
Previous code made an assumption that the power on value of global control MSR has enabled all fixed and general purpose counters properly. However, this is not the case for certain Intel processors, such as Atom - and it might also be firmware dependent. Each enable bit in IA32_PERF_GLOBAL_CTRL is AND'ed with the enable bits for all privilege levels in the respective IA32_PERFEVTSELx or IA32_PERF_FIXED_CTR_CTRL MSRs to start/stop the counting of respective counters. Counting is enabled if the AND'ed results is true; counting is disabled when the result is false. The end result is that all fixed counters are always disabled on Atom processors because the assumption is just invalid. Fix this by not initializing the ctrl-mask out of the global MSR, but setting it to perf_counter_mask.

2009-06-24ide: relax DMA info validity checkingBartlomiej Zolnierkiewicz
There are some broken devices that report multiple DMA xfer modes enabled at once (ATA spec doesn't allow it) but otherwise work fine with DMA so just delete ide_id_dma_bug(). [ As discovered by detective work by Frans and Bart, due to how handling of the ID block was handled before commit c419993 ("ide-iops: only clear DMA words on setting DMA mode") this check was always seeing zeros in the fields or other similar garbage. Therefore this check wasn't actually checking anything. Now that the tests actually check the real bits, all we see are devices that trigger the check yet work perfectly fine, therefore killing this useless check is the best thing to do. -DaveM ] Reported-by: Frans Pop <elendil@planet.nl> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: David S.

2009-06-24ide-cd: Don't warn on bogus block size unless it actually matters.David S. Miller
Frans Pop reported that his CDROM drive reports a blocksize of 2352, and this causes new warnings due to commit e8e7b9eb11c34ee18bde8b7011af41938d1ad667 ("ide-cd: fix oops when using growisofs"). What we're trying to do is make sure that "blocklen >> SECTOR_BITS" is something the block layer won't choke on. And for Frans' case "2352 >> SECTOR_BITS" is equal to "2048 >> SECTOR_BITS", and thats "4". So warning in this case gives no real benefit.
