This is v3 of a solution [1] (based on Will's, Catalin's and Mark's off-line suggestions) to move such common code in a single place: drivers/base/arch_topology.c (by creating such file and conditionally compiling it for arm and arm64 only). First 4 patches are actually fixes for the current code. Patch 5 is the actual refactoring. Patch 6 is a minor change suggested by Greg and can be squashed as needed. Patch 7 removes one of the extern symbols by changing a bit the now common code. Patch 8 removes the remaining externs (as required by Russell during v1 review) by creating a new header file include/linux/arch_topology.h and including that from arm, arm64 and drivers. Last patch addresses Dietmar's comments to v1 and adds a 'atd_' prefix to interfaces exported by drivers code and used by arch (and potentially others in the future). Changes from v2: - rebase on top of 4.11-rc4 - fix various problems pointed out by Greg, thanks for the review! (see patch 5 for details) The set is based on top of linux/master (4.11-rc4 c02ed2e75ef4) and it is also available from: git://linux-arm.org/linux-jl.git upstream/default_caps_factorize-v3 Best, - Juri [1] v1 - https://marc.info/?l=linux-kernel&m=148483680119355&w=2 v2 - https://marc.info/?l=linux-kernel&m=148663344018205&w=2 Juri Lelli (9): Documentation: arm: fix wrong reference number in DT definition Documentation/ABI: add information about cpu_capacity arm: fix return value of parse_cpu_capacity arm: remove wrong CONFIG_PROC_SYSCTL ifdef arm, arm64: factorize common cpu capacity default code drivers: remove useless comment from base/arch_topology.c arm,arm64,drivers: reduce scope of cap_parsing_failed arm,arm64,drivers: move externs in a new header file arm,arm64,drivers: add a prefix to drivers arch_topology interfaces Documentation/ABI/testing/sysfs-devices-system-cpu | 7 + Documentation/devicetree/bindings/arm/cpus.txt | 4 +- arch/arm/Kconfig | 1 + arch/arm/kernel/topology.c | 221 +------------------ arch/arm64/Kconfig | 1 + arch/arm64/kernel/topology.c | 226 +------------------ drivers/base/Kconfig | 8 + drivers/base/Makefile | 1 + drivers/base/arch_topology.c | 241 +++++++++++++++++++++ include/linux/arch_topology.h | 17 ++ 10 files changed, 288 insertions(+), 439 deletions(-) create mode 100644 drivers/base/arch_topology.c create mode 100644 include/linux/arch_topology.h -- 2.10.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
