2016-04-20ARM: dts: r8a7779: Correct interrupt type for ARM TWDGeert Uytterhoeven
The ARM TWD interrupt is a private peripheral interrupt (PPI), and per the ARM GIC documentation, whether the type for PPIs can be set is IMPLEMENTATION DEFINED. For R-Car H1 devices the PPI type cannot be set, and so when we attempt to set the type for the ARM TWD interrupt it fails. This has gone unnoticed because it fails silently, and because we cannot re-configure the type it has had no impact. Nevertheless fix the type for the TWD interrupt so that it matches the hardware configuration. Based on patches by Jon Hunter for Tegra20/30 and OMAP4.

2016-04-20ARM: dts: r8a7793: add CAN clocks to device treeSimon Horman
The R-Car CAN controllers can derive the CAN bus clock not only from their peripheral clock input (clkp1) but also from the other internal clock (clkp2) and external clock fed on CAN_CLK pin. Describe those clocks in the device tree along with the USB_EXTAL clock from which clkp2 is derived. Based on work by Sergei Shtylyov for the r8a7791 SoC.

2016-03-25mm, kasan: stackdepot implementation. Enable stackdepot for SLABAlexander Potapenko
Implement the stack depot and provide CONFIG_STACKDEPOT. Stack depot will allow KASAN store allocation/deallocation stack traces for memory chunks. The stack traces are stored in a hash table and referenced by handles which reside in the kasan_alloc_meta and kasan_free_meta structures in the allocated memory chunks. IRQ stack traces are cut below the IRQ entry point to avoid unnecessary duplication. Right now stackdepot support is only enabled in SLAB allocator. Once KASAN features in SLAB are on par with those in SLUB we can switch SLUB to stackdepot as well, thus removing the dependency on SLUB stack bookkeeping, which wastes a lot of memory. This patch is based on the "mm: kasan: stack depots" patch originally prepared by Dmitry Chernenkov. Joonsoo has said that he plans to reuse the stackdepot code for the mm/page_owner.c debugging facility.

2016-03-25arch, ftrace: for KASAN put hard/soft IRQ entries into separate sectionsAlexander Potapenko
KASAN needs to know whether the allocation happens in an IRQ handler. This lets us strip everything below the IRQ entry point to reduce the number of unique stack traces needed to be stored. Move the definition of __irq_entry to <linux/interrupt.h> so that the users don't need to pull in <linux/ftrace.h>. Also introduce the __softirq_entry macro which is similar to __irq_entry, but puts the corresponding functions to the .softirqentry.text section.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "There are only three patches this time, most other changes to files in include/asm-generic tend to go through the tree of whoever depends on the change. Two patches are cleanups for stuff that is no longer needed, the main change is to adapt the generic version of BUG_ON() for CONFIG_BUG=n to make it behave consistently with BUG(). This avoids undefined behavior along with a number of warnings about that undefined behavior in randconfig builds when we keep going on after hitting a BUG_ON()" * tag 'asm-generic-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic: remove old nonatomic-io wrapper files asm-generic: default BUG_ON(x) to if(x)BUG() asm-generic: page.h: Remove useless get_user_page and free_user_page
