* lib/mpi: mpi_write_sgl(): purge redundant pointer arithmeticNicolai Stange2016-04-051-2/+1
| | | | | | | | | | | | | | | | | | | Within the copying loop in mpi_write_sgl(), we have if (lzeros) { ... p -= lzeros; y = lzeros; } p = p - (sizeof(alimb) - y); If lzeros == 0, then y == 0, too. Thus, lzeros gets subtracted and added back again to p. Purge this redundancy. Signed-off-by: Nicolai Stange <nicstange@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* lib/mpi: mpi_write_sgl(): fix style issue with lzero decrementNicolai Stange2016-04-051-2/+2
| | | | | | | | | | | | | | | | | | | | Within the copying loop in mpi_write_sgl(), we have if (lzeros > 0) { ... lzeros -= sizeof(alimb); } However, at this point, lzeros < sizeof(alimb) holds. Make this fact explicit by rewriting the above to if (lzeros) { ... lzeros = 0; } Signed-off-by: Nicolai Stange <nicstange@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* lib/mpi: mpi_write_sgl(): fix skipping of leading zero limbsNicolai Stange2016-04-051-12/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if the number of leading zeros is greater than fits into a complete limb, mpi_write_sgl() skips them by iterating over them limb-wise. However, it fails to adjust its internal leading zeros tracking variable, lzeros, accordingly: it does a p -= sizeof(alimb); continue; which should really have been a lzeros -= sizeof(alimb); continue; Since lzeros never decreases if its initial value >= sizeof(alimb), nothing gets copied by mpi_write_sgl() in that case. Instead of skipping the high order zero limbs within the loop as shown above, fix the issue by adjusting the copying loop's bounds.

* hwrng: exynos - Runtime suspend device after initKrzysztof Kozlowski2016-04-051-1/+2
| | | | | | | | | | | | | | The driver uses pm_runtime_put_noidle() after initialization so the device might remain in active state if the core does not read from it (the read callback contains regular runtime put). The put_noidle() was chosen probably to avoid unneeded suspend and resume cycle after the initialization. However for this purpose autosuspend is enabled so it is safe to runtime put just after the initialization.

Look at what went wrong, by looking at the output of that test, in tools/perf/tarpkg Admittedly, this should be shortcircuited to showing what went wrong directly from the 'make build-test' step, but lets first fix this tarpkg one and the problem it spotted, which should be fixed by adding some extra file to the tools/perf/MANIFEST so that detached tarballs continue being self contained and build successfully.

" e23604edac2a Merge branch 'timers-nohz-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Now that we have introduced atomic_fetch_or(), fetch_or() is only used by the scheduler in order to deal with thread_info flags which type can vary across architectures. Lets confine fetch_or() back to the scheduler so that we encourage future users to use the more robust and well typed atomic_t version instead. While at it, fetch_or() gets robustified, pasting improvements from a previous patch by Ingo Molnar that avoids needless expression re-evaluations in the loop.

| * | timers/nohz: Convert tick dependency mask to atomic_tFrederic Weisbecker2016-03-293-34/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tick dependency mask was intially unsigned long because this is the type on which clear_bit() operates on and fetch_or() accepts it. But now that we have atomic_fetch_or(), we can instead use atomic_andnot() to clear the bit. This consolidates the type of our tick dependency mask, reduce its size on structures and benefit from possible architecture optimizations on atomic_t operations.

Not to mention fetch_or() doesn't refer to any namespace, adding even more confusion. So lets provide an atomic_t version. Current and next users of fetch_or() are thus encouraged to use atomic_t.
