With tickless kernel and software coordination os P-states, ondemand can look at wrong idle statistics. This can happen when ondemand sampling is happening on CPU 0 and due to software coordination sampling also looks at utilization of CPU 1. If CPU 1 is in tickless state at that moment, its idle statistics will not be uptodate and CPU 0 thinks CPU 1 is idle for less amount of time than it actually is. This can be resolved by looking at all the busy times of CPUs, which is accurate, even with tickless, and use that to determine idle time in a round about way (total time - busy time). Thanks to Arjan for originally reporting the ondemand bug on Lenovo T61. Signed-off-by:

Visualize-EG, Graffiti and A4450A graphics cards on PARISC can be configured in double-buffer and standard mode, but the stifb driver supports standard mode only. This patch detects double-buffered cards more reliable. It is a real bugfix for a very nasty problem for all parisc users which have wrongly configured their graphic card. The problem: The stifb graphics driver will not detect that the card is wrongly configured and then nevertheless just enables the graphics mode, which it shouldn't. In the end, the user will see no further updates / boot messages on the screen. We had documented this problem already on our FAQ (http://parisc-linux.org/faq/index.html#viseg "Why do I get corrupted graphics with my Vis-EG/Graffiti/A4450A card?") but people still run into this problem. So having this fix in as early as possible can help us. Signed-off-by:

Need to initialize map_bh.b_state to zero. Otherwise, in case of a faulty user-buffer its possible to go into dio_zero_block() and submit a page by mistake - since it checks for buffer_new(). http://marc.info/?l=linux-kernel&m=118551339032528&w=2 akpm: Linus had a (better) patch to just do a kzalloc() in there, but it got lost.

This patch causes device-mapper to reject any barrier requests. This is done since most of the targets won't handle this correctly anyway. So until the situation improves it is better to reject these requests at the first place. Since barrier requests won't get to the targets, the checks there can be removed. Signed-off-by:

The handling of the re-registration case is wrong here; the "test" that was returned from auth_domain_lookup will not be used again, so that reference should be put. And auth_domain_lookup never did anything with "new" in this case, so we should just clean it up ourself. Thanks to Akinobu Mita for bug report, analysis, and testing.

The value of nperbucket calculated here is too small--we should be rounding up instead of down--with the result that the index j in the following loop can overflow the raparm_hash array. At least in my case, the next thing in memory turns out to be export_table, so the symptoms I see are crashes caused by the appearance of four zeroed-out export entries in the first bucket of the hash table of exports (which were actually entries in the readahead cache, a pointer to which had been written to the export table in this initialization code). It looks like the bug was probably introduced with commit fce1456a ("knfsd: make the readahead params cache SMP-friendly"). Cc: Greg Banks <gnb@melbourne.sgi.com> Signed-off-by:
