[PATCH v7 0/2] context tracker support for arm64

by Larry Bassel

Implement and enable context tracking for arm64 (which is a prerequisite for FULL_NOHZ support). This patchset builds upon earlier work by Kevin Hilman and is based on Will Deacon's tree. Changes v6 to v7: * Rename parameter of ct_user_exit from restore to syscall Changes v5 to v6: * Don't save far_el1 in x26 in el0_dbg path (not needed) * TIF_NOHZ processes go through the slow path (so no register save/restore is needed in ct_user_enter) Changes v4 to v5: * Improvement to code restoring far_el1 (suggested by Christopher Covington) * Improvement to register save/restore in ct_user_enter Changes v3 to v4: * Rename parameter of ct_user_exit from save to restore * Rebased patch to Will Deacon's tree (branch remotes/origin/aarch64 of git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git) Changes v2 to v3: * Save/restore necessary registers in ct_user_enter and ct_user_exit * Annotate "error paths" out of el0_sync with ct_user_exit Changes v1 to v2: * Save far_el1 in x26 temporarily Larry Bassel (2): arm64: adjust el0_sync so that a function can be called arm64: enable context tracking arch/arm64/Kconfig | 1 + arch/arm64/include/asm/thread_info.h | 4 +++ arch/arm64/kernel/entry.S | 58 +++++++++++++++++++++++++++++++----- 3 files changed, 56 insertions(+), 7 deletions(-) -- 1.8.3.2

[PATCH V4 0/3] cpufreq: add support for intermediate (stable) frequencies

by Viresh Kumar

Doug raised many important concerns on V3: https://www.mail-archive.com/linux-kernel@vger.kernel.org/msg645134.html and so here is another iteration with improvements. @Stephen: I have dropped you Tested-by's as patches are updated and requires a retest, sorry for that :( Douglas Anderson, recently pointed out an interesting problem due to which udelay() was expiring earlier than it should. While transitioning between frequencies few platforms may temporarily switch to a stable frequency, waiting for the main PLL to stabilize. For example: When we transition between very low frequencies on exynos, like between 200MHz and 300MHz, we may temporarily switch to a PLL running at 800MHz. No CPUFREQ notification is sent for that. That means there's a period of time when we're running at 800MHz but loops_per_jiffy is calibrated at between 200MHz and 300MHz. And so udelay behaves badly. To get this fixed in a generic way, lets introduce another set of callbacks get_intermediate() and target_intermediate(), only for drivers with target_index() and CPUFREQ_ASYNC_NOTIFICATION unset. get_intermediate should return a stable intermediate frequency platform wants to switch to, and target_intermediate() should set CPU to to that frequency, before jumping to the frequency corresponding to 'index'. Core will take care of sending notifications and driver doesn't have to handle them in target_intermediate() or target_index(). This patchset also update Tegra to use this new infrastructure and is already tested by Stephen. V3->V4: - Allow get_intermediate() to return zero when we don't need to switch to intermediate first - Get rid of 'goto' and create another routine for handling intermediate freqs - Allow target_index() to fail, its not a crime :) - Fix tegra driver to return zero from get_intermediate() for few situations (refer to patch 3/4) - Fix issues with tegra's patch, like s/rate/rate * 1000 - Overall there are more modifications that what Doug requested as I felt we need better support from core. - Looks much better now, thanks Doug :) V2-V3: - Fix spelling error: s/Uset/Used - Update tegra with the changes Stephen suggested - Include a dependency patch sent separately earlier (3/4) V1-V2: Almost changed completely, V1 was here: https://lkml.org/lkml/2014/5/15/40 Viresh Kumar (3): cpufreq: handle calls to ->target_index() in separate routine cpufreq: add support for intermediate (stable) frequencies cpufreq: Tegra: implement intermediate frequency callbacks Documentation/cpu-freq/cpu-drivers.txt | 29 ++++++++- drivers/cpufreq/cpufreq.c | 111 ++++++++++++++++++++++++++------- drivers/cpufreq/tegra-cpufreq.c | 81 ++++++++++++++---------- include/linux/cpufreq.h | 25 ++++++++ 4 files changed, 186 insertions(+), 60 deletions(-) -- 2.0.0.rc2

[PATCH V2 1/3] regulator: return -EINVAL from regulator_set_voltage() for !CONFIG_REGULATOR

by Viresh Kumar

Currently regulator_set_voltage() returns zero when support for regulators isn't present in kernel, i.e. CONFIG_REGULATOR=n. Make it return -EINVAL to propagate error instead of success here. Audit of all users of this routine is done to make sure nothing breaks due to this change.
