Tejun Heo | 19df0c2 | 2011-01-25 14:26:50 +0100 | [diff] [blame] | 730 | * Macro which expands to output section for percpu area. |
| 731 | * |
| 732 | * @cacheline is used to align subsections to avoid false cacheline |
| 733 | * sharing between subsections for different purposes. |
| 734 | * |
| 735 | * If @vaddr is not blank, it specifies explicit base address and all |
| 736 | * percpu symbols will be offset from the given address. If blank, |
| 737 | * @vaddr always equals @laddr + LOAD_OFFSET. |
Tejun Heo | 3e5d8f9 | 2009-01-13 20:41:35 +0900 | [diff] [blame] | 738 | * |
| 739 | * @phdr defines the output PHDR to use if not blank. Be warned that |
| 740 | * output PHDR is sticky. If @phdr is specified, the next output |
| 741 | * section in the linker script will go there too. @phdr should have |
| 742 | * a leading colon. |
| 743 | * |
Tejun Heo | 3ac6cff | 2009-01-30 16:32:22 +0900 | [diff] [blame] | 744 | * Note that this macros defines __per_cpu_load as an absolute symbol. |
