kexec/i386: remove PAGE_SIZE alignment from relocate_kernel
Impact: save kernel .text by loosening kexec page alignment This patch removes PAGE_SIZE alignment from relocate_kernel(). Before kexec jump patches are merged, control page is mapped to relocate_kernel in kexec page tables, so relocate_kernel must be PAGE_SIZE aligned. Now, control page is mapped to identity mapped address, so relocate_kernel need not to be PAGE_SIZE aligned any more. This can reduce a few KB from kernel text segement.
