increased overhead in some places. If unsure say N here.

+ entire low memory range.
- If you have doubts about the BIOS (e.g. suspend/resume does not
- work or there's kernel crashes after certain hardware hotplug
- events) and it's not AMI or Phoenix, then you might want to enable
- X86_CHECK_BIOS_CORRUPTION=y to allow the kernel to check typical
