 * Linker-emitted symbols that bracket each section of the kernel image.
 *
 * The lumeos.lds.S linker script defines these as the start / end
 * addresses of contiguous regions.  Code that walks a section
 * (relocate_kernel walks .rela.dyn, the C++ ctor loop walks
 * .init_array, the VMM mapping code walks .text vs .rodata, ...)
 * imports the pair via this header.
 *
 * Mirrors Linux arch/riscv/include/asm/sections.h / asm-generic/sections.h.
 * Each name and pair is identical to Linux so that direct ports of mm/init.c
 * relocate_kernel logic compile unchanged against LumeOS.
