about the config_linux settings for the kernel:

why is this configured:

CONFIG_HIGHMEM4G=y
CONFIG_HIGHMEM=y
CONFIG_HIGHIO=y

Support for highmem is only worth when the system has more than 4g, and then, there is a penalty for each page access. also, pages are bigger (so more memory can be dimensioned).

This should be a more practical configuration:

CONFIG_NOHIGHMEM=y
# CONFIG_HIGHMEM4G is not set
# CONFIG_HIGHMEM64G is not set
# CONFIG_HIGHMEM is not set
