- Move alignment to page size of init data outside ifdef for BLK_DEV_INITRD.
  The reservation up to page size of memory after init data was previously
  not done if BLK_DEV_INITRD was undefined.
  This caused a kernel oops when init memory pages were freed after startup,
  data placed in the same page as the last init memory would also be freed
  and reused, with disastrous results.

- Use macros for initcalls and .text sections.

- Replace hardcoded page size constant with PAGE_SIZE define.

- Change include/asm-cris/page.h to use the _AC macro to instead
  of testing __ASSEMBLY__.
