For ARM64, when tracing with tracepoint events, the IP and pstate are set to 0, preventing the perf code parsing the callchain and resolving the symbols correctly. ./perf record -e sched:sched_switch -g --call-graph dwarf ls [ perf record: Captured and wrote 0.146 MB perf.data ] ./perf report -f Samples: 194 of event 'sched:sched_switch', Event count (approx.): 194 Children Self Command Shared Object Symbol 100.00% 100.00% ls [unknown] [.] 0000000000000000 The fix is to implement perf_arch_fetch_caller_regs for ARM64, which fills several necessary registers used for callchain unwinding, including pc,sp, fp and spsr . With this patch, callchain can be parsed correctly as follows: ...... + 2.63% 0.00% ls [kernel.kallsyms] [k] vfs_symlink + 2.63% 0.00% ls [kernel.kallsyms] [k] follow_down + 2.63% 0.00% ls [kernel.kallsyms] [k] pfkey_get + 2.63% 0.00% ls [kernel.kallsyms] [k] do_execveat_common.isra.33 - 2.63% 0.00% ls [kernel.kallsyms] [k] pfkey_send_policy_notify pfkey_send_policy_notify pfkey_get v9fs_vfs_rename page_follow_link_light link_path_walk el0_svc_naked .......

* 'for-next/cpu-init' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: ARM64: kernel: unify ACPI and DT cpus initialization ARM64: kernel: make cpu_ops hooks DT agnostic
-
Lorenzo Pieralisi authored
The code that initializes cpus on arm64 is currently split in two different code paths that carry out DT and ACPI cpus initialization. Most of the code executing SMP initialization is common and should be merged to reduce discrepancies between ACPI and DT initialization and to have code initializing cpus in a single common place in the kernel. This patch refactors arm64 SMP cpus initialization code to merge ACPI and DT boot paths in a common file and to create sanity checks that can be reused by both boot methods. Current code assumes PSCI is the only available boot method when arm64 boots with ACPI; this can be easily extended if/when the ACPI parking protocol is merged into the kernel. Signed-off-by:

ARM64 CPU operations such as cpu_init and cpu_init_idle take a struct device_node pointer as a parameter, which corresponds to the device tree node of the logical cpu on which the operation has to be applied. With the advent of ACPI on arm64, where MADT static table entries are used to initialize cpus, the device tree node parameter in cpu_ops hooks become useless when booting with ACPI, since in that case cpu device tree nodes are not present and can not be used for cpu initialization. The current cpu_init hook requires a struct device_node pointer parameter because it is called while parsing the device tree to initialize CPUs, when the cpu_logical_map (that is used to match a cpu node reg property to a device tree node) for a given logical cpu id is not set up yet. This means that the cpu_init hook cannot rely on the of_get_cpu_node function to retrieve the device tree node corresponding to the logical cpu id passed in as parameter, so the cpu device tree node must be passed in as a parameter to fix this catch-22 dependency cycle. This patch reshuffles the cpu_logical_map initialization code so that the cpu_init cpu_ops hook can safely use the of_get_cpu_node function to retrieve the cpu device tree node, removing the need for the device tree node pointer parameter. In the process, the patch removes device tree node parameters from all cpu_ops hooks, in preparation for SMP DT/ACPI cpus initialization consolidation. Signed-off-by:

The documented semantics of flush_cache_all are not possible to provide for arm64 (short of flushing the entire physical address space by VA), and there are currently no users; KVM uses VA maintenance exclusively, cpu_reset is never called, and the only two users outside of arch code cannot be built for arm64. While cpu_soft_reset and related functions (which call flush_cache_all) were thought to be useful for kexec, their current implementations only serve to mask bugs. For correctness kexec will need to perform maintenance by VA anyway to account for system caches, line migration, and other subtleties of the cache architecture. As the extent of this cache maintenance will be kexec-specific, it should probably live in the kexec code. This patch removes flush_cache_all, and related unused components, preventing further abuse.

Two watchdog changes that came through different trees had a non conflicting conflict, that is, one changed the semantics of a variable but no actual code conflict happened. So the merge appeared fine, but the resulting code did not behave as expected. Commit 195daf66 ("watchdog: enable the new user interface of the watchdog mechanism") changes the semantics of watchdog_user_enabled, which thereafter is only used by the functions introduced by b3738d29 ("watchdog: Add watchdog enable/disable all functions"). There further appears to be a distinct lack of serialization between setting and using watchdog_enabled, so perhaps we should wrap the {en,dis}able_all() things in watchdog_proc_mutex. This patch fixes a s2r failure reported by Michal; which I cannot readily explain. But this does make the code internally consistent again. Reported-and-tested-by:

In commit 8ff16cf7 ("Documentation: devicetree: m25p80: add "nor-jedec" binding"), we added a generic "nor-jedec" binding to catch all mostly-compatible SPI NOR flash which can be detected via the READ ID opcode (0x9F). This was discussed and reviewed at the time, however objections have come up since then as part of this discussion: http://lkml.kernel.org/g/20150511224646.GJ32500@ld-irv-0074 It seems the parties involved agree that "jedec,spi-nor" does a better job of capturing the fact that this is SPI-specific, not just any NOR flash. This binding was only merged for v4.1-rc1, so it's still OK to change the naming. At the same time, let's move the documentation to a better name. Next up: stop referring to code (drivers/mtd/devices/m25p80.c) from the documentation. Signed-off-by:
