If the kernel may make use of 64 bit addresses outside of the compatibility address space then we need to set KX such that those accesses can succeed. Do so for MIPS64 kernels.

CM3 has 64 bit GCR_ERROR_* registers, but the code in mips_cm_error_report was previously only reading 32 bits of it in MIPS32 kernels. Fix by splitting the reads for CM2 & CM3, and making use of the read64_ variants of the accessor function for CM3.

If we run a MIPS32 kernel on a system using CM3 we may still need to access 64 bit GCRs, as will be done in later patches. Allow this by having the read64_gcr_* accessor functions perform 2 x 32 bit reads on those systems.

A boundary exists beyond which the timer frequency becomes high enough that timer interrupts saturate the system and either cause it to slow to a crawl or stop functioning entirely. Where that boundary lies depends upon a number of factors such as the overhead of each interrupt and the overall speed of the CPU, but correlates strongly with the clock frequency at which the CPU runs. When running on emulators during bringup or debug of a CPU that clock frequency is very low, which results in the boundary at which the timer frequency becomes unsustainable being very low. The current minimum of 48Hz pushes against boundary in certain situations in current systems. Allow the kernel to be configured for a 24Hz timer frequency in order to avoid problems on such slow running systems.

ARCH_USE_BUILTIN_BSWAP will use __builtin_bswap16(), __builtin_bswap32() and __builtin_bswap64() where available. This allows better instruction scheduling. On pre-R2 processors it will result in 32 bit and 64 bit swapping being performed in a call to a __bswapsi2() rsp. __bswapdi2() functions, so we add these, too. For a 4.2 kernel with GCC 4.9 this yields the following kernel sizes: text data bss dec hex filename 3996071 155804 88992 4240867 40b5e3 vmlinux ip22 baseline 3985687 159900 88992 4234579 409d53 vmlinux ip22 + bswap patch 6913157 378552 251024 7542733 7317cd vmlinux ip27 baseline 6878581 378552 251024 7508157 7290bd vmlinux ip27 + bswap patch 5773777 268752 187424 6229953 5f0fc1 vmlinux malta baseline 5773401 268752 187424 6229577 5f0e49 vmlinux malta + bswap patch Presumably the code size improvments yield better cache hit rate thus better performance compensating for the extra function call but this will still need to be benchmarked.

If the CLEAN_SHUTDOWN flag is not set when a cache is loaded then all cache blocks are marked as dirty and a full writeback occurs. __commit_transaction() is responsible for setting/clearing CLEAN_SHUTDOWN (based the flags_mutator that is passed in). Fix this issue, of the cache's on-disk flags being wrong, by making sure __commit_transaction() does not reset the flags after the mutator has altered the flags in preparation for them being serialized to disk. before: sb_flags = mutator(le32_to_cpu(disk_super->flags)); disk_super->flags = cpu_to_le32(sb_flags); disk_super->flags = cpu_to_le32(cmd->flags); after: disk_super->flags = cpu_to_le32(cmd->flags); sb_flags = mutator(le32_to_cpu(disk_super->flags)); disk_super->flags = cpu_to_le32(sb_flags); Reported-by: NBogdan Vasiliev <bogdan.vasiliev@gmail.com> Signed-off-by: NJoe Thornber <ejt@redhat.com> Signed-off-by: NMike Snitzer <snitzer@redhat.com> Cc: stable@vger.kernel.org

Mapping an image with a long parent chain (e.g. image foo, whose parent is bar, whose parent is baz, etc) currently leads to a kernel stack overflow, due to the following recursion in the reply path: rbd_osd_req_callback() rbd_obj_request_complete() rbd_img_obj_callback() rbd_img_parent_read_callback() rbd_obj_request_complete() ...

Currently we leak parent_spec and trigger a "parent reference underflow" warning if rbd_dev_create() in rbd_dev_probe_parent() fails. The problem is we take the !parent out_err branch and that only drops refcounts; parent_spec that would've been freed had we called rbd_dev_unparent() remains and triggers rbd_warn() in rbd_dev_parent_put() - at that point we have parent_spec != NULL and parent_ref == 0, so counter ends up being -1 after the decrement.

Other bug fixes include - a partial revert of a broken tegra gpio patch - irq affinity for arm ccn - suspend on one Armada 385 machine - enable ZONE_DMA to avoid an OMAP crash for over 2GB RAM - turning on a regulator on beagleboard-x15 for HDMI - making the omap gpmc debug code visible - setup of orion network switch - a rare build regression for pxa" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (22 commits) ARM: OMAP2+: Fix imprecise external abort caused by bogus SRAM init thermal: exynos: Fix register read in TMU ARM: OMAP2+: Fix oops with LPAE and more than 2GB of memory ARM: tegra: Comment out gpio-ranges properties ARM: dts: uniphier: fix IRQ number for devices on PH1-LD6b ref board drivers/perf: arm_pmu: avoid CPU device_node reference leak bus: arm-ccn: Fix irq affinity setting on CPU migration bus: arm-ccn: Handle correctly no-more-cpus case ARM: mvebu: correct a385-db-ap compatible string ARM: meson6: DTS: Fix wrong reg mapping and IRQ numbers MAINTAINERS: Update Allwinner entry and add new maintainer ARM: ux500: modify initial levelshifter status ARM: pxa: fix pxa3xx DFI lockup hack Documentation: ARM: List new omap MMC requirements memory: omap-gpmc: dump "before" state before first modification memory: omap-gpmc: Fix unselectable debug option for GPMC ARM: dts: am57xx-beagle-x15: set VDD_SD to always-on ARM: dts: Fix audio card detection on Peach boards ARM: EXYNOS: Fix double of_node_put() when parsing child power domains ARM: orion: Fix DSA platform device after mvmdio conversion ...

Merge tag 'trace-fixes-v4.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "Running tests on other changes, the system locked up due to lots of warnings. It was caused by the stack tracer triggering a warning about using rcu_dereference() when RCU was not watching. This can happen due to the fact that the stack tracer uses the function tracer to check each function, and there are functions that may be called and traced when RCU stopped watching. Namely when a function is called just before going idle or to userspace and after RCU stopped watching that current CPU. The first patch makes sure that RCU is watching when the stack tracer uses RCU. The second patch is to make sure that the stack tracer does not get called by functions in NMI, as it's not NMI safe" * tag 'trace-fixes-v4.3-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Do not allow stack_tracer to record stack in NMI tracing: Have stack tracer force RCU to be watching
