Pull clock framework fixes from Michael Turquette: "The clk fixes for 4.0-rc4 comprise three themes. First are the usual driver fixes for new regressions since v3.19. Second are fixes to the common clock divider type caused by recent changes to how we round clock rates. This affects many clock drivers that use this common code. Finally there are fixes for drivers that improperly compared struct clk pointers (drivers must not deref these pointers). While some of these drivers have done this for a long time, this did not cause a problem until we started generating unique struct clk pointers for every consumer. A new function, clk_is_match was introduced to get these drivers working again and they are fixed up to no longer deref the pointers themselves" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: ASoC: kirkwood: fix struct clk pointer comparing ASoC: fsl_spdif: fix struct clk pointer comparing ARM: imx: fix struct clk pointer comparing clk: introduce clk_is_match clk: don't export static symbol clk: divider: fix calculation of initial best divider when rounding to closest clk: divider: fix selection of divider when rounding to closest clk: divider: fix calculation of maximal parent rate for a given divider clk: divider: return real rate instead of divider value clk: qcom: fix platform_no_drv_owner.cocci warnings clk: qcom: fix platform_no_drv_owner.cocci warnings clk: qcom: Add PLL4 vote clock clk: qcom: lcc-msm8960: Fix PLL rate detection clk: qcom: Fix slimbus n and m val offsets clk: ti: Fix FAPLL parent enable bit handling

kasan, module, vmalloc: rework shadow allocation for modules

2015-03-13T01:46:08Z

Current approach in handling shadow memory for modules is broken. Shadow memory could be freed only after memory shadow corresponds it is no longer used. vfree() called from interrupt context could use memory its freeing to store 'struct llist_node' in it: void vfree(const void *addr) { ... if (unlikely(in_interrupt())) { struct vfree_deferred *p = this_cpu_ptr(&vfree_deferred); if (llist_add((struct llist_node *)addr, &p->list)) schedule_work(&p->wq); Later this list node used in free_work() which actually frees memory. Currently module_memfree() called in interrupt context will free shadow before freeing module's memory which could provoke kernel crash. So shadow memory should be freed after module's memory. However, such deallocation order could race with kasan_module_alloc() in module_alloc(). Free shadow right before releasing vm area. At this point vfree()'d memory is not used anymore and yet not available for other allocations. New VM_KASAN flag used to indicate that vm area has dynamically allocated shadow memory so kasan frees shadow only if it was previously allocated.

clk: introduce clk_is_match

2015-03-11T22:56:59Z

Some drivers compare struct clk pointers as a means of knowing if the two pointers reference the same clock hardware. This behavior is dubious (drivers must not dereference struct clk), but did not cause any regressions until the per-user struct clk patch was merged. Now the test for matching clk's will always fail with per-user struct clk's. clk_is_match is introduced to fix the regression and prevent drivers from comparing the pointers manually.
