CRIS v10: vmlinux.lds.S: ix kernel oops on boot and use common defines
- 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__.
