During boot we leave the idmap in place until paging_init, as we previously had to wait for the zero page to become allocated and accessible. Now that we have a statically-allocated zero page, we can uninstall the idmap much earlier in the boot process, making it far easier to spot accidental use of physical addresses. This also brings the cold boot path in line with the secondary boot path. Signed-off-by:
