The literal pool entry for identifying the vectors base is the only piece of information in the trampoline page that identifies the true location of the kernel. This patch moves it into a page-aligned region of the .rodata section and maps this adjacent to the trampoline text via an additional fixmap entry, which protects against any accidental leakage of the trampoline contents.
