[PATCH] lib/Kconfig: make PREEMPT_COUNT depend on PREEMPT in DEBUG_ATOMIC_SLEEP

by Yang Shi

When building non-preempt kernel (PREEMPT_NONE), PREEMPT_COUNT is still enabled if DEBUG_ATOMIC_SLEEP is enabled. But, it sounds not make sense to have PREEMPT_COUNT set in non-preempt kernel. So, make PREEMPT_COUNT depend on PREEMPT here.

[LSK-v4.1 PATCH] ARM: 8464/1: Update all mm structures with section adjustments

by David Brown

From: Laura Abbott <labbott(a)redhat.com> commit 08925c2f124f1bac6152a8b234268f9874fc70a5 upstream. Currently, when updating section permissions to mark areas RO or NX, the only mm updated is current->mm. This is working off the assumption that there are no additional mm structures at the time. This may not always hold true. (Example: calling modprobe early will trigger a fork/exec). Ensure all mm structres get updated with the new section information.

Hi Mark, Alex, Please consider following linaro-android pull request for "linux-linaro-lsk-v3.14-android" LSK branch for 16.02. This pull request contain patches cherry-picked from android-3.14 branch of https://android.googlesource.com/kernel/common and few linaro-android fixes already submitted to AOSP gerrit for review. android-3.14 test merge into lsk-v3.14-android branch had quiet a few complicated merge conflicts and it was easier to just cherry-pick the AOSP only changes for this pull request and skip the upstream/backported patches from AOSP which are already pulled by LTS.

[PATCH] arm64: reenable interrupt when handling ptrace breakpoint

The kernel just send out a SIGTRAP signal when handling ptrace breakpoint in debug exception, so it sounds safe to have interrupt enabled if it is not disabled by the parent process.

[PATCH V4 0/7] cpufreq: Locking fixes and cleanups

by Viresh Kumar

Hi Rafael, These are rest of the patches that fix some more locking issues with policy->rwsem and do some minor optimization/cleanups. These were part of the 13 patch series which was sent earlier. The last patch is new, and does what I suggested to one of your commits. V3->V4: - Reordered all the patches and created a new series. - s/global/common for common tunables - One new patch @Juri/Shilpa: I have added your Tested-by for the first 6 patches, please let me know if you don't want to add that. Viresh Kumar (7): cpufreq: Merge cpufreq_offline_prepare/finish routines cpufreq: Call __cpufreq_governor() with policy->rwsem held cpufreq: Remove cpufreq_governor_lock cpufreq: governor: Move common sysfs tunables to cpufreq_governor.c cpufreq: governor: No need to manage state machine now cpufreq: conservative: Update sample_delay_ns immediately cpufreq: ondemand: Rearrange od_dbs_timer() to void updating delay drivers/cpufreq/cpufreq.c | 93 +++++++++--------- drivers/cpufreq/cpufreq_conservative.c | 80 +++------------- drivers/cpufreq/cpufreq_governor.c | 170 ++++++++++++++++++++++++++++----- drivers/cpufreq/cpufreq_governor.h | 16 +++- drivers/cpufreq/cpufreq_ondemand.c | 153 +++++------------------------ 5 files changed, 240 insertions(+), 272 deletions(-) -- 2.7.1.370.gb2aa7f8

[LSK-v3.18 PATCH] ARM: 8464/1: Update all mm structures with section adjustments

by David Brown

From: Laura Abbott <labbott(a)redhat.com> commit 08925c2f124f1bac6152a8b234268f9874fc70a5 upstream. Currently, when updating section permissions to mark areas RO or NX, the only mm updated is current->mm. This is working off the assumption that there are no additional mm structures at the time. This may not always hold true. (Example: calling modprobe early will trigger a fork/exec). Ensure all mm structres get updated with the new section information. Reviewed-by: Kees Cook <keescook(a)chromium.org> Signed-off-by: Laura Abbott <labbott(a)fedoraproject.org> Signed-off-by: Russell King <rmk+kernel(a)arm.linux.org.uk> Signed-off-by: David Brown <david.brown(a)linaro.org> --- (resending with proper CCs) Bringing in this fix allows CONFIG_DEBUG_RODATA to work on ARM.

[GIT PULL] [lsk-v3.18-android] linaro-android-3.18 topic branch updates for 16.02

by Amit Pundir

Hi Mark, Alex, Please consider following linaro-android pull request for "linux-linaro-lsk-v3.18-android" LSK branch for 16.02. I run into few conflicts while merging aosp/android-3.18 branch: Conflicts: * arch/arm/Kconfig Pick changes from AOSP commit 7514b4f5c78b "FROMLIST: arm: mm: support ARCH_MMAP_RND_BITS." and skip changes from linaro-android commit 3daddaa28cbf "arm: enable ARCH_MMAP_RND_BITS only for MMU platforms" which are no longer needed. * arch/arm64/mm/mmap.c Pick changes from AOSP commit 527d350d5e91 "FROMLIST: arm64: mm: support ARCH_MMAP_RND_BITS." over changes from LTS commit c4a7bf89fbff "arm64/mm: Remove hack in mmap randomize layout" which are no longer valid. * include/net/sock.h LTS and AOSP both cherry-picked/backported upstream commit 1d0ab253872c "net: add sk_fullsock() helper" but AOSP removed TCPF_NEW_SYN_RECV check part from the backport. Lets stick with AOSP changes. * mm/page_alloc.c Conflict here is due to LTS and AOSP both cherrypicking upstream commit 99592d598eca "mm: when stealing freepages, also take pages created by splitting buddy page" and couple more of AOSP backported commits f34a097caa34 "UPSTREAM: mm: always steal split buddies in fallback allocations" and a4edf85a8b92 "UPSTREAM: mm: more aggressive page stealing for UNMOVABLE allocations". Resolution: Keep all of AOSP changes. I have also logged this ^^ merge conflict + resolution part in the merge commit.

[PATCH] scsi: fdomain: add missing CONFIG_ to PCMCIA

by Yang Shi

There are some "#ifdef PCMCIA" in the driver code, but all of them missed CONFIG_ prefix. Correct PCMCIA to CONFIG_PCMCIA. Signed-off-by: Yang Shi <yang.shi(a)linaro.org> --- I happened to find this problem when I was tracking down another problem, however this driver looks very old, not sure if anybody cares about it or not.

[PATCH V2 0/7] cpufreq: governors: Fix ABBA lockups

by Viresh Kumar

Hi Rafael, Here is the V2 with updated patches as suggested by you guys. These are pushed here: git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/governor-kobject The first four patches are for 4.5, if possible and others you can keep for 4.6. V1->V2: - Improved changelogs, thanks Rafael. - Added new dbs_data->mutex to avoid concurrent updates to tunables. - Moved kobj_type to common_dbs_data. - Updated macros to static inline routines - s/show/governor_show - s/store/governor_store - Improved comments @Juri: More testing requested :) Viresh Kumar (7): cpufreq: governor: Treat min_sampling_rate as a governor-specific tunable cpufreq: governor: New sysfs show/store callbacks for governor tunables cpufreq: governor: Drop unused macros for creating governor tunable attributes Revert "cpufreq: Drop rwsem lock around CPUFREQ_GOV_POLICY_EXIT" cpufreq: Merge cpufreq_offline_prepare/finish routines cpufreq: Call __cpufreq_governor() with policy->rwsem held cpufreq: Remove cpufreq_governor_lock drivers/cpufreq/cpufreq.c | 93 +++++++++++++---------------- drivers/cpufreq/cpufreq_conservative.c | 79 +++++++++---------------- drivers/cpufreq/cpufreq_governor.c | 105 +++++++++++++++++++++++++-------- drivers/cpufreq/cpufreq_governor.h | 104 ++++++++------------------------ drivers/cpufreq/cpufreq_ondemand.c | 79 +++++++++---------------- include/linux/cpufreq.h | 4 -- 6 files changed, 203 insertions(+), 261 deletions(-) -- 2.7.0.79.gdc08a19

[PATCH V3 00/13] cpufreq: governors: Fix ABBA lockups

by Viresh Kumar

Hi Rafael, Things look much much better now. I have rebased this series over pm/bleeding-edge, that has all your patches. I have moved ahead and done few more changes in this series, that should get rid of all the lockdeps we were getting earlier, that includes fixing lockdep issue in update_sampling_rate() that we were chasing. These are pushed here again: git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/governor-kobject @Juri/Shilpa: Can you please confirm if all the issues got resolved now ? V2->V3: - The first patch from V2, that was moving min_sampling_rate to per governor structure was dropped, as you suggested. - Also, I have moved common tunables to struct dbs_data now, which you also suggested sometime back. - Last 5 patches are all new and fix rest of the issues we were facing. -- viresh Viresh Kumar (13): cpufreq: governor: Create generic macro for global tuners cpufreq: governor: Move common tunables to 'struct dbs_data' cpufreq: governor: New sysfs show/store callbacks for governor tunables cpufreq: governor: Drop unused macros for creating governor tunable attributes Revert "cpufreq: Drop rwsem lock around CPUFREQ_GOV_POLICY_EXIT" cpufreq: Merge cpufreq_offline_prepare/finish routines cpufreq: Call __cpufreq_governor() with policy->rwsem held cpufreq: Remove cpufreq_governor_lock cpufreq: governor: Move common sysfs tunables to cpufreq_governor.c cpufreq: governor: No need to manage state machine now cpufreq: governor: Keep list of policy_dbs within dbs_data cpufreq: ondemand: Traverse list of policy_dbs in update_sampling_rate() cpufreq: conservative: Update sample_delay_ns immediately drivers/cpufreq/cpufreq.c | 98 ++++++------ drivers/cpufreq/cpufreq_conservative.c | 143 ++++-------------- drivers/cpufreq/cpufreq_governor.c | 266 +++++++++++++++++++++++++-------- drivers/cpufreq/cpufreq_governor.h | 156 ++++++++----------- drivers/cpufreq/cpufreq_ondemand.c | 241 +++++------------------------ include/linux/cpufreq.h | 4 - 6 files changed, 381 insertions(+), 527 deletions(-) -- 2.7.1.370.gb2aa7f8

[PATCH V2 00/16] PM / OPP: Introduce APIs to transition OPPs

by Viresh Kumar

Hi Guys, This patchset add APIs in OPP layer to allow OPPs transitioning from within OPP layer. Currently all OPP users need to replicate the same code to switch between OPPs. While the same can be handled easily by OPP-core. The first 7 patches update the OPP core to introduce the new APIs and the next Nine patches update cpufreq-dt for the same. 11 out of 17 are already Reviewed by Stephen, only few are left :) @Rafael: I will send a pull request once that is done. Testing: - Tested on exynos 5250-arndale (dual-cortex-A15) - Tested for both Old-V1 bindings and New V2 bindings - Tested with regulator names as: 'cpu-supply' and 'cpu0-supply' - Tested with Unsupported supply ranges as well, to check the opp-disable logic V1->V2: - Locking fixes as suggested by Stephen - Made dev_pm_opp_put_regulator(), as we can't rely on dev_name() to get name of the supply (Stephen/Mark B.) - Other minor modifications Viresh Kumar (16): PM / OPP: get/put regulators from OPP core PM / OPP: Disable OPPs that aren't supported by the regulator PM / OPP: Introduce dev_pm_opp_get_max_volt_latency() PM / OPP: Introduce dev_pm_opp_get_max_transition_latency() PM / OPP: Parse clock-latency and voltage-tolerance for v1 bindings PM / OPP: Manage device clk PM / OPP: Add dev_pm_opp_set_rate() cpufreq: dt: Convert few pr_debug/err() calls to dev_dbg/err() cpufreq: dt: Rename 'need_update' to 'opp_v1' cpufreq: dt: OPP layers handles clock-latency for V1 bindings as well cpufreq: dt: Pass regulator name to the OPP core cpufreq: dt: Unsupported OPPs are already disabled cpufreq: dt: Reuse dev_pm_opp_get_max_transition_latency() cpufreq: dt: Use dev_pm_opp_set_rate() to switch frequency cpufreq: dt: drop references to DT node cpufreq: dt: No need to allocate resources anymore drivers/base/power/opp/core.c | 420 ++++++++++++++++++++++++++++++++++++++++++ drivers/base/power/opp/opp.h | 13 ++ drivers/cpufreq/cpufreq-dt.c | 290 ++++++++++------------------- include/linux/pm_opp.h | 27 +++ 4 files changed, 555 insertions(+), 195 deletions(-) -- 2.7.0.79.gdc08a19

[RFC V5] Add gup trace points support

by Yang Shi

v5: * Fixed a typo introduced by v4 rebase * Removed redundant "#define CREATE_TRACE_POINTS" from architecture specifc gup.c v4: * Adopted Steven's suggestion to use "unsigned int" for nr_pages to save space in ring buffer since it is unlikely to have more than 0xffffffff pages are touched by gup in one invoke * Remove unnecessray type cast v3: * Adopted suggestion from Dave Hansen to move the gup header include to the last * Adopted comments from Steven: - Use DECLARE_EVENT_CLASS and DEFINE_EVENT - Just keep necessary TP_ARGS * Moved archtichture specific fall-backable fast version trace point after the do while loop since it may jump to the slow version. * Not implement recording return value since Steven plans to have it in generic tracing code v2: * Adopted commetns from Steven - remove all reference to tsk->comm since it is unnecessary for non-sched trace points - reduce arguments for __get_user_pages trace point and update mm/gup.c accordingly * Added Ralf's acked-by for patch 4/7. Some background about why I think this might be useful. When I was profiling some hugetlb related program, I got page-faults event doubled when hugetlb is enabled. When I looked into the code, I found page-faults come from two places, do_page_fault and gup. So, I tried to figure out which play a role (or both) in my use case. But I can't find existing finer tracing event for sub page-faults in current mainline kernel. So, I added the gup trace points support to have finer tracing events for page-faults. The below events are added: __get_user_pages __get_user_pages_fast fixup_user_fault Both __get_user_pages and fixup_user_fault call handle_mm_fault. Just added trace points to raw version __get_user_pages since all variants will call it finally to do real work. Although __get_user_pages_fast doesn't call handle_mm_fault, it might be useful to have it to distinguish between slow and fast version.
