* lis3: separate configuration function for 8 bit deviceSamu Onkalo2010-05-25

* scripts/get_maintainer.pl: default to not include unspecified tagsFlorian Mickler2010-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the default of the option --git-all-signature-types to be disabled by default. The effect being, that only certain (currently Signed-Off-By:, Acked-by: and Reviewed-By:) tags are used to get adresses of potential maintainers. Motivated is this change by the desire to not 'spam' people unnecessary: A Tested-By or a Reported-By is not ment as a hint that those people want to/are able to review patches to the code in question. In a quest to find resilient statistics for this i came up with this: I produced a list of all the tag-signers not already covered with a signed-off/acked/reviewed tag somewhere in the last year of git history. Those were 650 addresses of "assumed non-developers". And to check if those "assumed non-developers" are professional testers/reporters worth cc'ing, i then counted their total appearences in the git log: 469 were mentioned only once. 123 were mentioned twice. 38 three times 8 four times 5 six times 5 five times 1 eight times 1 fourteen times I believe this supports my thesis, that the ''non-maintainer-tags'' are not actively useful for patch-review. (except probably the guy mentioned fourteen times...) But of course one could also find arguments to poke holes in this statistics, for example does this statistic not include code-locality: A tested-by on a patch that touches some specific piece of code can be more worth than a signed-off in another part of the tree. But... let's play it safe and let's err on the "safe" side meaning to not spam those people when in doubt. We already have the signed-off's and Maintainers file. So this should be ok. And if need be, the maintainers can always forward the patch.

* scripts/get_maintainer.pl: optionally ignore non-maintainer signaturesJoe Perches2010-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using --git to determine who to send a patch to, get_maintainers will currently include all signatures. This can include signers that simply report an issue or test a patch. Signers that use this tag are not necessarily good candidates to review new patches. This patch allows get_maintainers to optionally restrict output to only signatures that use Signed-off-by:, Acked-by:, or Reviewed-by:. Signed-off-by: is included because those are people who are responsible for the code. Acked-by: is questionable, but as signers that use this tag tend to be active linux gatekeepers, false positives are tolerable. Reviewed-by: is included because signers responsible for the code thought that the review feedback for a changeset by that signer was valuable. This patch has been modified from Florian's original submission to change the supported signature types to the canonical forms and use slightly different spacing. A couple of spacing issues were also corrected in the original source. The command line argument was also renamed.

This was corrected with linux 2.6.3 when Keith M Wesolowski changed the implementation to use the parisc approach of having an array of spinlocks to protect the atomic_t. These warnings were also removed from the sparc implementation when the new implementation was merged in BKrev:402e4949VThdc6D3iaosSFUgabMfvw, but the warning still remained in some other places without any 24-bit-only atomic_t implementation inside the kernel.

Benefits over using a private pagevec: neater code, 128 bytes fewer stack used, percpu lru ordering is preserved, and finally don't need to flush pagevec before returning so batching may be shared with other LRU insertions."

* hangcheck-timer: fix x86_32 bugsYury Polyanskiy2010-05-25
| | | | | | | | | | | | | | | | | | | | | | | | drivers/char/hangcheck-timer.c is doubly broken. When the overflown value of TIMER_FREQ is abnormally low, it spams the syslog with KERN_CRIT messages "Hangcheck: hangcheck value past margin!" But whether it happens or not depends on HZ and lpj in a complex way. People have hit it occasionally as far as google search can tell. First, the following line overflows unsigned long: # define TIMER_FREQ (HZ*loops_per_jiffy) Second, and more importantly, loops_per_jiffy has little to do with the con= version from the the time scale of get_cycles() (aka rdtsc) to the time scale of jiffies. The attached patch resolves both of the problems.

* endian: #define __BYTE_ORDERJoakim Tjernlund2010-05-25
| | | | | | | | | | | | | | | | | Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.

* cpuidle: add a repeating pattern detector to the menu governorArjan van de Ven2010-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the menu governor uses the (corrected) next timer as key item for predicting the idle duration. It turns out that there are specific cases where this breaks down: There are cases where we have a very repetitive pattern of idle durations, where the idle period is pretty much the same, for reasons completely unrelated to the next timer event. Examples of such repeating patterns are network loads with irq mitigation, the mouse moving but in theory also the wifi beacons. This patch adds a relatively simple detector for such repeating patterns, where the standard deviation of the last 8 idle periods is compared to a threshold. With this extra predictor in place, measurements show that the DECAY factor can now be increased (the decaying average will now decay slower) to get an even more stable result.
