/**

 * PERCPU_VADDR - define output section for percpu area

 * PERCPU_SECTION - define output section for percpu area

 * @cacheline: cacheline size

 * @vaddr: explicit base address (optional)

 * @phdr: destination PHDR (optional)

 *

 * Macro which expands to output section for percpu area.

 *

 * @cacheline is used to align subsections to avoid false cacheline

 * sharing between subsections for different purposes.

 *

 * If @vaddr is not blank, it specifies explicit base address and all

 * percpu symbols will be offset from the given address.  If blank,

 * @vaddr always equals @laddr + LOAD_OFFSET.

 *

 * @phdr defines the output PHDR to use if not blank.  Be warned that

 * output PHDR is sticky.  If @phdr is specified, the next output

 * section in the linker script will go there too.  @phdr should have

 * a leading colon.

 *

 * Note that this macros defines __per_cpu_load as an absolute symbol.

 * If there is no need to put the percpu section at a predetermined

 * address, use PERCPU_SECTION.

 * Align to PAGE_SIZE and outputs output section for percpu area.  This

 * __per_cpu_start will be identical.

 *

 * This macro is equivalent to ALIGN(PAGE_SIZE); PERCPU_VADDR(@cacheline,,)

 * except that __per_cpu_load is defined as a relative symbol against

 * .data..percpu which is required for relocatable x86_32 configuration.
