  "message": "percpu: align percpu readmostly subsection to cacheline\n\nCurrently percpu readmostly subsection may share cachelines with other\npercpu subsections which may result in unnecessary cacheline bounce\nand performance degradation.\n\nThis patch adds @cacheline parameter to PERCPU() and PERCPU_VADDR()\nlinker macros, makes each arch linker scripts specify its cacheline\nsize and use it to align percpu subsections.\n\nThis is based on Shaohua\u0027s x86 only patch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Shaohua Li \u003cshaohua.li@intel.com\u003e\n",
