According to AK09911 datasheet, if reset gpio is provided then deassert reset on ak8975_power_on() and assert reset on ak8975_power_off(). Without reset's deassertion during ak8975_power_on(), driver's probe fails on ak8975_who_i_am() while checking for device identity for AK09911 chip. AK09911 has an active low reset gpio to handle register's reset. AK09911 datasheet says that, if not used, reset pin should be connected to VID. This patch emulates this situation. Signed-off-by:

The ADC architecture on PMIC7 is changed as compared to PMIC5. The major change from PMIC5 is that all SW communication to ADC goes through PMK8350, which communicates with other PMICs through PBS when the ADC on PMK8350 works in master mode. The SID register is used to identify the PMICs with which the PBS needs to communicate. Add support for the same. Signed-off-by:

Add documentation for PMIC7 ADC peripheral. For the PMIC7-type PMICs, ADC peripheral is present in HW for the following PMICs: PMK8350, PM8350, PM8350b, PMR735a and PMR735b. Of these, only the ADC peripheral on PMK8350 is exposed directly to SW. If SW needs to communicate with ADCs on other PMICs, it specifies the PMIC to PMK8350 through the newly added SID register and communication between PMK8350 ADC and other PMIC ADCs is carried out through PBS(Programmable Boot Sequence) at the firmware level. In addition, add definitions for ADC channels and virtual channel definitions (combination of ADC channel number and PMIC SID number) per PMIC, to be used by ADC clients for PMIC7. Signed-off-by:

We may want to get rid of the iio_priv_to_dev() helper. That's a bit uncertain at this point. The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. For this driver, removing the iio_priv_to_dev() helper means passing the iio_dev object on hts221_allocate_buffers() & hts221_allocate_trigger(). Signed-off-by:

Pull the Kernel Concurrency Sanitizer from Thomas Gleixner: "The Kernel Concurrency Sanitizer (KCSAN) is a dynamic race detector, which relies on compile-time instrumentation, and uses a watchpoint-based sampling approach to detect races. The feature was under development for quite some time and has already found legitimate bugs. Unfortunately it comes with a limitation, which was only understood late in the development cycle: It requires an up to date CLANG-11 compiler CLANG-11 is not yet released (scheduled for June), but it's the only compiler today which handles the kernel requirements and especially the annotations of functions to exclude them from KCSAN instrumentation correctly. These annotations really need to work so that low level entry code and especially int3 text poke handling can be completely isolated. A detailed discussion of the requirements and compiler issues can be found here: https://lore.kernel.org/lkml/CANpmjNMTsY_8241bS7=XAfqvZHFLrVEkv_uM4aDUWE_kh3Rvbw@mail.gmail.com/ We came to the conclusion that trying to work around compiler limitations and bugs again would end up in a major trainwreck, so requiring a working compiler seemed to be the best choice. For Continous Integration purposes the compiler restriction is manageable and that's where most xxSAN reports come from. For a change this limitation might make GCC people actually look at their bugs. Some issues with CSAN in GCC are 7 years old and one has been 'fixed' 3 years ago with a half baken solution which 'solved' the reported issue but not the underlying problem. The KCSAN developers also ponder to use a GCC plugin to become independent, but that's not something which will show up in a few days. Blocking KCSAN until wide spread compiler support is available is not a really good alternative because the continuous growth of lockless optimizations in the kernel demands proper tooling support" * tag 'locking-kcsan-2020-06-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (76 commits) compiler_types.h, kasan: Use __SANITIZE_ADDRESS__ instead of CONFIG_KASAN to decide inlining compiler.h: Move function attributes to compiler_types.h compiler.h: Avoid nested statement expression in data_race() compiler.h: Remove data_race() and unnecessary checks from {READ,WRITE}_ONCE() kcsan: Update Documentation to change supported compilers kcsan: Remove 'noinline' from __no_kcsan_or_inline kcsan: Pass option tsan-instrument-read-before-write to Clang kcsan: Support distinguishing volatile accesses kcsan: Restrict supported compilers kcsan: Avoid inserting __tsan_func_entry/exit if possible ubsan, kcsan: Don't combine sanitizer with kcov on clang objtool, kcsan: Add kcsan_disable_current() and kcsan_enable_current_nowarn() kcsan: Add __kcsan_{enable,disable}_current() variants checkpatch: Warn about data_race() without comment kcsan: Use GFP_ATOMIC under spin lock Improve KCSAN documentation a bit kcsan: Make reporting aware of KCSAN tests kcsan: Fix function matching in report kcsan: Change data_race() to no longer require marking racing accesses kcsan: Move kcsan_{disable,enable}_current() to kcsan-checks.h ... -

Pull atomics rework from Thomas Gleixner: "Peter Zijlstras rework of atomics and fallbacks. This solves two problems: 1) Compilers uninline small atomic_* static inline functions which can expose them to instrumentation. 2) The instrumentation of atomic primitives was done at the architecture level while composites or fallbacks were provided at the generic level. As a result there are no uninstrumented variants of the fallbacks. Both issues were in the way of fully isolating fragile entry code pathes and especially the text poke int3 handler which is prone to an endless recursion problem when anything in that code path is about to be instrumented. This was always a problem, but got elevated due to the new batch mode updates of tracing. The solution is to mark the functions __always_inline and to flip the fallback and instrumentation so the non-instrumented variants are at the architecture level and the instrumentation is done in generic code. The latter introduces another fallback variant which will go away once all architectures have been moved over to arch_atomic_*" * tag 'locking-urgent-2020-06-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: locking/atomics: Flip fallbacks and instrumentation asm-generic/atomic: Use __always_inline for fallback wrappers -

In some rare cases, for input data over 32 KB, lzo-rle could encode two different inputs to the same compressed representation, so that decompression is then ambiguous (i.e. data may be corrupted - although zram is not affected because it operates over 4 KB pages). This modifies the compressor without changing the decompressor or the bitstream format, such that: - there is no change to how data produced by the old compressor is decompressed - an old decompressor will correctly decode data from the updated compressor - performance and compression ratio are not affected - we avoid introducing a new bitstream format In testing over 12.8M real-world files totalling 903 GB, three files were affected by this bug. I also constructed 37M semi-random 64 KB files totalling 2.27 TB, and saw no affected files. Finally I tested over files constructed to contain each of the ~1024 possible bad input sequences; for all of these cases, updated lzo-rle worked correctly. There is no significant impact to performance or compression ratio. Signed-off-by:

After commit 12abc5ee ("tcp: add tcp_sock_set_nodelay") and commit c488aead ("tcp: add tcp_sock_set_user_timeout"), building the kernel with OCFS2_FS=y but without INET=y causes it to fail with: ld: fs/ocfs2/cluster/tcp.o: in function `o2net_accept_many': tcp.c:(.text+0x21b1): undefined reference to `tcp_sock_set_nodelay' ld: tcp.c:(.text+0x21c1): undefined reference to `tcp_sock_set_user_timeout' ld: fs/ocfs2/cluster/tcp.o: in function `o2net_start_connect': tcp.c:(.text+0x2633): undefined reference to `tcp_sock_set_nodelay' ld: tcp.c:(.text+0x2643): undefined reference to `tcp_sock_set_user_timeout' This is due to tcp_sock_set_nodelay() and tcp_sock_set_user_timeout() being declared in linux/tcp.h and defined in net/ipv4/tcp.c, which depend on TCP/IP being enabled.

Action Required memory error should happen only when a processor is about to access to a corrupted memory, so it's synchronous and only affects current process/thread. Recently commit 872e9a20 ("mm, memory_failure: don't send BUS_MCEERR_AO for action required error") fixed the issue that Action Required memory could unnecessarily send SIGBUS to the processes which share the error memory. But we still have another issue that we could send SIGBUS to a wrong thread. This is because collect_procs() and task_early_kill() fails to add the current process to "to-kill" list. So this patch is suggesting to fix it. With this fix, SIGBUS(BUS_MCEERR_AR) is never sent to non-current process/thread. Signed-off-by:

Patch series "hwpoison: fixes signaling on memory error" This is a small patchset to solve issues in memory error handler to send SIGBUS to proper process/thread as expected in configuration. Please see descriptions in individual patches for more details. This patch (of 2): Early-kill policy is controlled from two types of settings, one is per-process setting prctl(PR_MCE_KILL) and the other is system-wide setting vm.memory_failure_early_kill. Users expect per-process setting to override system-wide setting as many other settings do, but early-kill setting doesn't work as such. For example, if a system configures vm.memory_failure_early_kill to 1 (enabled), a process receives SIGBUS even if it's configured to explicitly disable PF_MCE_KILL by prctl(). That's not desirable for applications with their own policies. This patch is suggesting to change the priority of these two types of settings, by checking sysctl_memory_failure_early_kill only when a given process has the default kill policy. Note that this patch is solving a thread choice issue too. Originally, collect_procs() always chooses the main thread when vm.memory_failure_early_kill is 1, even if the process has a dedicated thread for memory error handling. SIGBUS should be sent to the dedicated thread if early-kill is enabled via vm.memory_failure_early_kill as we are doing for PR_MCE_KILL_EARLY processes. Signed-off-by:
