434 *
435 * Macro which expands to output section for percpu area. If @vaddr
436 * is not blank, it specifies explicit base address and all percpu
437 * symbols will be offset from the given address. If blank, @vaddr
438 * always equals @laddr + LOAD_OFFSET.
439 *
440 * @phdr defines the output PHDR to use if not blank. Be warned that
441 * output PHDR is sticky. If @phdr is specified, the next output
442 * section in the linker script will go there too. @phdr should have
443 * a leading colon.
444 *
Tejun Heo3ac6cff2009-01-30 16:32:22 +0900445 * Note that this macros defines __per_cpu_load as an absolute symbol.
446 * If there is no need to put the percpu section at a predetermined
447 * address, use PERCPU().
