- 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__.

* It is VERY DANGEROUS to fiddle around with the symbols in this

* script. It is for example quite vital that all generated sections
|
|
* that are used are actually named here, otherwise the linker will
|
|
* put them at the end, where the init stuff is which is FREED after
|
|
* the kernel has booted.
