Issue: # perf probe -a 'do_sched_setscheduler pid policy param->sched_priority@user' did not work before. Fix: Make: # perf probe -a 'do_sched_setscheduler pid policy param->sched_priority@user' output equivalent to ftrace: # echo 'p:probe/do_sched_setscheduler _text+517384 pid=%r2:s32 policy=%r3:s32 sched_priority=+u0(%r4):s32' > /sys/kernel/debug/tracing/kprobe_events Other: 1. Right now, __match_glob() does not handle [u]<offset>. For now, use *u]<offset>. 2. @user attribute was introduced in commit 1e032f7c ("perf-probe: Add user memory access attribute support") Test: 1. perf probe -a 'do_sched_setscheduler pid policy param->sched_priority@user' 2 ./perf script sched 305669 [000] 1614458.838675: perf_bpf_probe:func: (2904e508) pid=261614 policy=2 sched_priority=1 3. cat /sys/kernel/debug/tracing/trace <...>-309956 [006] .... 1616098.093957: 0: prio: 1 Committer testing: Before: # perf probe -a 'do_sched_setscheduler pid policy param->sched_priority@user' param(type:sched_param) has no member sched_priority@user. Error: Failed to add events. # pahole sched_param struct sched_param { int sched_priority; /* 0 4 */ /* size: 4, cachelines: 1, members: 1 */ /* last cacheline: 4 bytes */ }; # After: # perf probe -a 'do_sched_setscheduler pid policy param->sched_priority@user' Added new event: probe:do_sched_setscheduler (on do_sched_setscheduler with pid policy sched_priority=param->sched_priority) You can now use it in all perf tools, such as: perf record -e probe:do_sched_setscheduler -aR sleep 1 # cat /sys/kernel/debug/tracing/kprobe_events p:probe/do_sched_setscheduler _text+1113792 pid=%di:s32 policy=%si:s32 sched_priority=+u0(%dx):s32 # Fixes: 1e032f7c ("perf-probe: Add user memory access attribute support") Signed-off-by: Sumanth Korikkar <sumanthk@linux.ibm.com> Reviewed-by: Thomas Richter <tmricht@linux.ibm.com> Acked-by: Masami Hiramatsu <mhiramat@kernel.org> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Ilya Leoshkevich <iii@linux.ibm.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Steven Rostedt (VMware) <rostedt@goodmis.org> Cc: bpf@vger.kernel.org LPU-Reference: 20200609081019.60234-2-sumanthk@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Pull remoteproc updates from Bjorn Andersson: "This introduces device managed versions of functions used to register remoteproc devices, add support for remoteproc driver specific resource control, enables remoteproc drivers to specify ELF class and machine for coredumps. It integrates pm_runtime in the core for keeping resources active while the remote is booted and holds a wake source while recoverying a remote processor after a firmware crash. It refactors the remoteproc device's allocation path to simplify the logic, fix a few cleanup bugs and to not clone const strings onto the heap. Debugfs code is simplifies using the DEFINE_SHOW_ATTRIBUTE and a zero-length array is replaced with flexible-array. A new remoteproc driver for the JZ47xx VPU is introduced, the Qualcomm SM8250 gains support for audio, compute and sensor remoteprocs and the Qualcomm SC7180 modem support is cleaned up and improved. The Qualcomm glink subsystem-restart driver is merged into the main glink driver, the Qualcomm sysmon driver is extended to properly notify remote processors about all other remote processors' state transitions" * tag 'rproc-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc: (43 commits) remoteproc: Fix an error code in devm_rproc_alloc() MAINTAINERS: Add myself as reviewer for Ingenic rproc driver remoteproc: ingenic: Added remoteproc driver remoteproc: Add support for runtime PM dt-bindings: Document JZ47xx VPU auxiliary processor remoteproc: wcss: Fix arguments passed to qcom_add_glink_subdev() remoteproc: Fix and restore the parenting hierarchy for vdev remoteproc: Fall back to using parent memory pool if no dedicated available remoteproc: Replace zero-length array with flexible-array remoteproc: wcss: add support for rpmsg communication remoteproc: core: Prevent system suspend during remoteproc recovery remoteproc: qcom_q6v5_mss: Remove unused q6v5_da_to_va function remoteproc: qcom_q6v5_mss: map/unmap mpss segments before/after use remoteproc: qcom_q6v5_mss: Drop accesses to MPSS PERPH register space dt-bindings: remoteproc: qcom: Replace halt-nav with spare-regs remoteproc: qcom: pas: Add SM8250 PAS remoteprocs dt-bindings: remoteproc: qcom: pas: Add SM8250 remoteprocs remoteproc: qcom_q6v5_mss: Extract mba/mpss from memory-region dt-bindings: remoteproc: qcom: Use memory-region to reference memory remoteproc: qcom: pas: Add SC7180 Modem support ...

The default remains to always read from primary, users can opt-in with the new crush_location and read_from_replica options. Note that reading from replica is safe for general use only since Octopus. - support for RADOS allocation hint flags (myself). Currently used by rbd to propagate the compressible/incompressible hint given with the new compression_hint map option and ready for passing on more advanced hints, e.g. based on fadvise() from the filesystem. - support for efficient cross-quota-realm renames (Luis Henriques) - assorted cap handling improvements and cleanups, particularly untangling some of the locking (Jeff Layton)" * tag 'ceph-for-5.8-rc1' of git://github.com/ceph/ceph-client: (29 commits) rbd: compression_hint option libceph: support for alloc hint flags libceph: read_from_replica option libceph: support for balanced and localized reads libceph: crush_location infrastructure libceph: decode CRUSH device/bucket types and names libceph: add non-asserting rbtree insertion helper ceph: skip checking caps when session reconnecting and releasing reqs ceph: make sure mdsc->mutex is nested in s->s_mutex to fix dead lock ceph: don't return -ESTALE if there's still an open file libceph, rbd: replace zero-length array with flexible-array ceph: allow rename operation under different quota realms ceph: normalize 'delta' parameter usage in check_quota_exceeded ceph: ceph_kick_flushing_caps needs the s_mutex ceph: request expedited service on session's last cap flush ceph: convert mdsc->cap_dirty to a per-session list ceph: reset i_requested_max_size if file write is not wanted ceph: throw a warning if we destroy session with mutex still locked ceph: fix potential race in ceph_check_caps ceph: document what protects i_dirty_item and i_flushing_item ...

Pull iommu updates from Joerg Roedel: "A big part of this is a change in how devices get connected to IOMMUs in the core code. It contains the change from the old add_device() / remove_device() to the new probe_device() / release_device() call-backs. As a result functionality that was previously in the IOMMU drivers has been moved to the IOMMU core code, including IOMMU group allocation for each device. The reason for this change was to get more robust allocation of default domains for the iommu groups. A couple of fixes were necessary after this was merged into the IOMMU tree, but there are no known bugs left. The last fix is applied on-top of the merge commit for the topic branches. Other than that change, we have: - Removal of the driver private domain handling in the Intel VT-d driver. This was fragile code and I am glad it is gone now. - More Intel VT-d updates from Lu Baolu: - Nested Shared Virtual Addressing (SVA) support to the Intel VT-d driver - Replacement of the Intel SVM interfaces to the common IOMMU SVA API - SVA Page Request draining support - ARM-SMMU Updates from Will: - Avoid mapping reserved MMIO space on SMMUv3, so that it can be claimed by the PMU driver - Use xarray to manage ASIDs on SMMUv3 - Reword confusing shutdown message - DT compatible string updates - Allow implementations to override the default domain type - A new IOMMU driver for the Allwinner Sun50i platform - Support for ATS gets disabled for untrusted devices (like Thunderbolt devices). This includes a PCI patch, acked by Bjorn. - Some cleanups to the AMD IOMMU driver to make more use of IOMMU core features. - Unification of some printk formats in the Intel and AMD IOMMU drivers and in the IOVA code. - Updates for DT bindings - A number of smaller fixes and cleanups. * tag 'iommu-updates-v5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (109 commits) iommu: Check for deferred attach in iommu_group_do_dma_attach() iommu/amd: Remove redundant devid checks iommu/amd: Store dev_data as device iommu private data iommu/amd: Merge private header files iommu/amd: Remove PD_DMA_OPS_MASK iommu/amd: Consolidate domain allocation/freeing iommu/amd: Free page-table in protection_domain_free() iommu/amd: Allocate page-table in protection_domain_init() iommu/amd: Let free_pagetable() not rely on domain->pt_root iommu/amd: Unexport get_dev_data() iommu/vt-d: Fix compile warning iommu/vt-d: Remove real DMA lookup in find_domain iommu/vt-d: Allocate domain info for real DMA sub-devices iommu/vt-d: Only clear real DMA device's context entries iommu: Remove iommu_sva_ops::mm_exit() uacce: Remove mm_exit() op iommu/sun50i: Constify sun50i_iommu_ops iommu/hyper-v: Constify hyperv_ir_domain_ops iommu/vt-d: Use pci_ats_supported() iommu/arm-smmu-v3: Use pci_ats_supported() ...

Starting from v4.19 commit 29ef680a ("memcg, oom: move out_of_memory back to the charge path") cgroup oom killer is no longer invoked only from page faults. Now it implements the same semantics as global OOM killer: allocation context invokes OOM killer and keeps retrying until success.

Rename the current flush_icache_range to flush_icache_user_range as per commit ae92ef8a ("PATCH] flush icache in correct context") there seems to be an assumption that it operates on user addresses.
