/* Nadir kernel linker script.
 *
 * Links the whole kernel (stage-2 entry + C code) as one flat binary loaded
 * by the boot sector at 0x10000. Virtual addresses equal physical ones: the
 * stage-2 page tables identity-map the first 1GB, so linked addresses work
 * as-is the moment long mode is on.
 *
 * Layout rules: the stage-2 entry (.boot32) must be the very first bytes of
 * the image, BSS exposes __bss_start/__bss_end for runtime zeroing, and
 * toolchain metadata sections are discarded so the binary is pure code+data.
