=== Highlights === * Lots of plumbers android mini-summit planning and discussions * Todd Poynor from Google implemented timerfd support for alarmtimers and asked me to review the changes for AOSP. The feature has been a todo of mine for awhile, so its very cool to see it implemented. Since they will be using this for Android, so I queued it for upstream as well. The hope is this would provide a proper upstream replacement for the android alarmdev. * Reviewed a number of community patches and queued a few of them for 3.11 * Worked with Minchan on a new iteration of the volatile range patchset. There's a bit of contention about approaches around the interface (he doesn't see some of the lsf-mm objections as an issue), so we're trying to sort that out. * Talked w/ tglx about getting DanielL to act as submaintainer for clockevent drivers. * Reviewed blueprints and did weekly email status * Submitted expense report for Dublin flight * Zoran found a timekeeping suspend bug, so worked with him to review his patch, get it to lkml, and queued for upstream. === Plans === * Answer some community questions on volatile ranges and Android's usage of ashmem * Try to address kdb-fiq concerns. * ION research/discussion === Issues === * NA

[PATCH] KVM: allow host header to be included even for !CONFIG_KVM

by Kevin Hilman

The new context tracking subsystem unconditionally includes kvm_host.h headers for the guest enter/exit macros. This causes a compile failure when KVM is not enabled. Fix by adding an IS_ENABLED(CONFIG_KVM) check to kvm_host so it can be included/compiled even when KVM is not enabled.

[ACTIVITY] (Linus Walleij) 2013-05-04 - 2013-05-17

by Linus Walleij

== Linus Walleij linusw == === Highlights === * Torvalds did pull the GPIO changes from Grant in the end. I have been spending some time on QA stuff like discussing with Fengguang @Intel on getting automated 0day builds of my kernel.org trees back on line and that is running smoothly now. Also figured out how to run Arnds buildall.mak script. * Collected a set of ux500 fixes post-v3.10-rc1 and sent a pull request to the ARM SoC maintainers. * Continued to apply DMA40 patches from Lee on a specific DMA40 branch targeted for ARM SoC. Got some ACKs and awaiting some more ACKs. A first branch will be prepared for pull request to ARM SoC soon-ish. * Discussed future ux500 work with Lee. * Reviewed lots of pinctrl code but have a hard time to keep up. I have collected a set of fixes to send to Torvalds. This is growing wildly... * Updated my profile @HR Connection as requested. * Reviewed TI-Nspire timer driver. === Plans === * Help Grant with stacking up some GPIO fixes. * Finalize U300 DT+multiplatform patch set. Maybe send a partial pull request with the stuff I have. * Integrate Integrator PCI patch set, then start to delete board files and convert to multiplatform. * Convert Nomadik pinctrl driver to register GPIO ranges from the gpiochip side. * Test the PL08x patches on the Ericsson Research PB11MPCore and submit platform data for using pl08x DMA on that platform. * Get hands dirty with regmap. === Issues === * Need a PCI branch at ARM SoC to request Integrator PCI DT patches to be pulled into. * Some impediments from internal turmoil @ST-Ericsson. Thanks, Linus Walleij

Hi Vikas Sajian, I agree with Tomasz Figa's opinion. Backlight/LCD framework should be used. eDP panel backlight on SMDK5210 board can be controlled by PWM; thus, pwm-backlight driver should be used. Also, eDP panel reset pin should be controlled by using platform-lcd driver. > > CCing Richard, Florian and linux-fbdev.

[PATCH] cpufreq: arm_big_little_dt: Register driver only if DT has valid data

by Viresh Kumar

If arm_big_little_dt driver is enabled, then it will always try to register with big LITTLE cpufreq core driver. In case DT doesn't have relevant data for cpu nodes, i.e. operating points aren't present, then we should exit early and shouldn't register with big LITTLE cpufreq core driver. Otherwise we will fail continuously from the driver->init() routine. This patch fixes this issue.

[PATCH V2 0/3] Emergency write support for virtio console devices.

by Pranavkumar Sawargaonkar

This patch-set implements early printk support for virtio console devices by adding and using emergency write register to virtio console's config space. The current virtio early printk code in kernel expects that hypervisor will provide some mechanism generally a hypercall to support early printk. This patch-set does not break existing hypercall based early print support. This implementation adds: 1. Emergency writeonly register named emerg_wr in virtio console's config space. 2. Host feature flags namely VIRTIO_CONSOLE_F_EMERG_WRITE for telling guest about early-write capability in console device. Emergency write mechanism: 1. When a guest wants to out some character, it has to simply write the character to emerg_wr register in config space of virtio console device.

[PATCH] ARM: add support for kernel mode NEON/VFP

by Ard Biesheuvel

In order to safely support the use of NEON or VFP instructions in kernel mode, some precautions need to be taken: - the userland context that may be present in the registers (even if the NEON/VFP is currently disabled) must be stored under the correct task (which may not be 'current' in the UP case), - to avoid having to keep track of additional vfpstates for the kernel side, disallow the use of NEON/VFP in interrupt context and run with preemption disabled, - after use, re-enable preemption and re-enable the lazy restore machinery by disabling the NEON/VFP unit. This patch adds the functions kernel_vfp_begin() and kernel_vfp_end() which take care of the above.

[PATCH V1 resend] cpufreq: Raname index as data in cpufreq_frequency_table

by Viresh Kumar

"Index" field of struct cpufreq_frequency_table was never index and isn't used at all by cpufreq core. And is only useful for cpufreq drivers for their personal use. Many people now a days blindly set it in ascending order with the assumption that core is using it for some work. This patch renames it to "data" as that's what its purpose it. All users of the same are fixed too.

kexec for armv7

by Pankaj Pandey

Hi, I am working on kexec for ARM(armv7 architecture ) on Linux-2.6.32.59. I am unable to boot secondary kernel zImage using kexec. It got hanged after "Uncompressing Linux.....done, b ooting the kernel." I debugged through hardware debugger and found issue in "arch/arm/kernel/head.S" at __turn_mmu_on which is failing to initialized the mmu. I will highly appreciate if you can suggest some pointers to debug this issue. kexec command use: kexec -l /home/zImage --command-line=`cat /proc/cmdline` kexec -e Thanks and Regards, Pankaj Pandey
