Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs when CONFIG_BLK_DEV_INITRAMFS is not selected. This saves another 4 kbytes on most platfoms (some reserve PAGE_SIZE for initramfs).

* 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.
