  "message": "x86: make percpu symbols zerobased on SMP\n\n[ Based on original patch from Christoph Lameter and Mike Travis. ]\n\nThis patch makes percpu symbols zerobased on x86_64 SMP by adding\nPERCPU_VADDR() to vmlinux.lds.h which helps setting explicit vaddr on\nthe percpu output section and using it in vmlinux_64.lds.S.  A new\nPHDR is added as existing ones cannot contain sections near address\nzero.  PERCPU_VADDR() also adds a new symbol __per_cpu_load which\nalways points to the vaddr of the loaded percpu data.init region.\n\nThe following adjustments have been made to accomodate the address\nchange.\n\n* code to locate percpu gdt_page in head_64.S is updated to add the\n  load address to the gdt_page offset.\n\n* __per_cpu_load is used in places where access to the init data area\n  is necessary.\n\n* pda-\u003edata_offset is initialized soon after C code is entered as zero\n  value doesn\u0027t work anymore.\n\nThis patch is mostly taken from Mike Travis\u0027 \"x86_64: Base percpu\nvariables at zero\" patch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n",
