Kernel: Make kernel symbols available much earlier in the boot process This adds a new section .ksyms at the end of the linker map, reserves 5MiB for it (which are after end_of_kernel_image so they get re-used once MemoryManager is initialized) and then embeds the symbol map into the kernel binary with objcopy. This also shrinks the .ksyms section to the real size of the symbol file (around 900KiB at the moment). By doing this we can make the symbol map available much earlier in the boot process, i.e. even before VFS is available. 2021-07-14 19:04:18 +00:00			`#!/bin/sh`

Kernel: Make new kernel build process work on macOS Use objcopy from the toolchain so that the changes introduced in 7236584 will succeed on macOS. Fixes #8768. 2021-07-15 08:17:58 +00:00			`OBJCOPY="${OBJCOPY:-objcopy}"`
