Message:

kernel: Some adjustments

• Mention NVME.
• Mention PAE (CONFIG_HIGHMEM64G) for 32-bit.
• Don't repeat the link to BLFS kernel config index twice on SysV. And don't display the long URL for it.
• Emphasis that BLFS UEFI kernel config is needed even if you'll use the UEFI bootloader of the host distro.

File:

• chapter10/kernel.xml (modified) (4 diffs)
