Here is a collection of fixes (and some intermixed cleanups) that were considered less important and thus not included in the later parts of the 3.9-rc cycle. It's a bit all over the map, contents wise. A series of ux500 fixes and cleanups, a bunch of various fixes for OMAP and tegra, and some for Freescale i.MX and even Qualcomm MSM. Note that there's also a patch on this branch to globally turn off -Wmaybe-uninitialized when building with -Os. It's been posted several times by Arnd and no dissent was raised, but nobody seemed interested to pick it up. So here it is, as the topmost patch. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJRggtQAAoJEIwa5zzehBx3TmYP/i4Kt3JDYEbYyAqNsH3nb0mN 3kLwViUxDdS/aZCXEaNYLwZBUgl1Zyz3oRd39zFCo4dRM2uG1AW+lC73AP3/eW6n 2oHxI43xzwjDNPxRkiipB4NXPyIoIdbRXM6/QIxXzM9zD3MJXj7BpBBpDgGAsLov BQ2r28idxZE6jB4puPjVZCuyG5UMjA0Ko2Fp2em7QXarQBBscDvhAtjqNZ3JPtlN thASsou1B8805J7jf5G8Wz6fNeVJg2wlWMgE9ywJpKFbut4cGM4riS/QvB0fTe6d tmkCae0bw3UD+D+N1gYcZpeGve8oPSHbeyhrSPAfI/wAVBh0J397MgJW5/f0vW8p DffLjQI+S450Kw0Bab41Tn0JnMnXtYUo56yjemdxa/NQJF34ycBFQ3HOm6nFxo7U 6tce2O775uvG0+rJfDbX6M+Mu7QoIi0p8sOdg0/W+pFK08xvaezsOc1NjqTvuYoC s/2LYiIJqVG6tFVU0i/46duQhdp0I/Oj7wXtFXH0ZvZPBz0cDaSU3irB3QA9pNt5 PI6JEBg0FUPUork24gShSUf7un4Itrjlq20HTkC9/z1skx87PbB3Wa7A8jnHeFme tpuPRvmfBWhIhp06AIA8znhDik9xuJ4B7ypsFNM0VyoV/qx+TSIHbViVQuwcOf9b nAidtuhMjE+P2sAu+VGU =bzsu -----END PGP SIGNATURE----- Merge tag 'fixes-nc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC non-critical fixes from Olof Johansson: "Here is a collection of fixes (and some intermixed cleanups) that were considered less important and thus not included in the later parts of the 3.9-rc cycle.
