[adding linaro-kernel, Andrey] Yes, it seems the base64 component is a misnomer, at least for now. Meanwhile, if this patch is targeted to the main linaro kernel, please send via the linaro-kernel list, cc'ing linaro-networking. If not, then perhaps a separate .conf file is in order? Anyway, I think we'd all prefer a resolution within the main linaro kernel for hugepage support. > > and we are building with it in our ci/job/linux-lng* scripts... perhaps those should be patched as well.

[PATCH v2 0/4] perf: parse the dwarf backtrace info from .debug_frame section

by Jean Pihet

On ARM the debug info is not present in the .eh_frame sections but in .debug_frame instead, in dwarf format. This patch set uses libunwind to load and parse the dwarf debug info from the .debug_frame section if no .eh_frame_hdr section is found; also it sets the hooks in the perf_regs and libunwind code for ARMv7. Dependencies: . if present, libunwind >= 1.1 is needed to prevent a segfault when parsing the dwarf info, . libunwind needs to be configured with --enable-debug-frame to prevent a linkage error. Note: --enable-debug-frame is automatically selected on ARM). The generated perf has been tested on ARMv7 (OMAP4, Marvell Armada XP) and x86_64, using the following commands: perf record -g [dwarf] -- <binary> perf report --sort symbol --call-graph --stdio Jean Pihet (2): perf tools: Check libunwind for availability of dwarf parsing feature perf: parse the .debug_frame section in case .eh_frame is not present Will Deacon (2): ARM: perf: add support for perf registers API ARM: perf: wire up perf_regs and unwind support for ARM arch/arm/Kconfig | 2 + arch/arm/include/uapi/asm/Kbuild | 1 + arch/arm/include/uapi/asm/perf_regs.h | 23 +++++++++++ arch/arm/kernel/Makefile | 1 + arch/arm/kernel/perf_regs.c | 30 ++++++++++++++ tools/perf/arch/arm/Makefile | 3 ++ tools/perf/arch/arm/include/perf_regs.h | 54 +++++++++++++++++++++++++ tools/perf/arch/arm/util/unwind.c | 48 ++++++++++++++++++++++ tools/perf/config/Makefile | 7 +++- tools/perf/config/feature-tests.mak | 11 ++++- tools/perf/util/unwind.c | 71 +++++++++++++++++++++++++-------- 11 files changed, 232 insertions(+), 19 deletions(-) create mode 100644 arch/arm/include/uapi/asm/perf_regs.h create mode 100644 arch/arm/kernel/perf_regs.c create mode 100644 tools/perf/arch/arm/include/perf_regs.h create mode 100644 tools/perf/arch/arm/util/unwind.c -- 1.7.11.7

[PATCH 0/4] driver core: Introduce initcall_driver() to eliminate boilerplate code

by Hanjun Guo

Lots of device drivers especially for platform/I2C/SPI bus devices, they want to be initialized earlier than other devices, so the driver use initcall such as subsys_initcall for the device initialization. But for those drivers, lots of them just do nothing special in xxx_initcall/module_exit, and produce lots of boilerplate. This patch set introduces a helper macro initcall_driver() to eliminate lots of boilerplate just like module_driver() did, and use it for platform/I2C/SPI bus devices. I use following command under the lastest kernel source code: $grep -r -E "*_initcall" drivers/ | cut -d":" -f1 |xargs grep -E "return platform_driver_register|return i2c_add_driver|return spi_register_driver" | cut -d":" -f1 | xargs grep "module_exit" | wc -l and get 205 hits, so if we use helper macro initcall_driver(), we can reduce thousands lines of code.
