 - The `memory_map` field contains an overview of the available physical memory. This tells our kernel how much physical memory is available in the system and which memory regions are reserved for devices such as the VGA hardware. The memory map can be queried from the BIOS or UEFI firmware, but only very early in the boot process. For this reason, it must be provided by the bootloader because there is no way for the kernel to retrieve it later. We will need the memory map later in this post.
 - The `physical_memory_offset` tells us the virtual start address of the physical memory mapping. By adding this offset to a physical address, we get the corresponding virtual address. This allows us to access arbitrary physical memory from our kernel.
-- This physical memory offset can be customized by adding a `[package.metadata.bootloader]` table in Cargo.toml and setting the field `physical-memory-offset = "0x0000f00000000000"` (or any other value). However, note that the bootloader can panic if it runs into physical address values that start to overlap with the the space beyond the offset, i.e., areas it would have previously mapped to some other early physical addresses. So in general, the higher the value (> 1 TiB), the better.

 The bootloader passes the `BootInfo` struct to our kernel in the form of a `&'static BootInfo` argument to our `_start` function. We don't have this argument declared in our function yet, so let's add it:
