When we have CONFIG_STRICT_KERNEL_RWX enabled, we try to split the
kernel linear (1:1) mapping so that the kernel text is in a separate

We could achieve that just by always using 64K pages for the linear

When we have CONFIG_STRICT_KERNEL_RWX enabled, we want to split the

Currently we always use a small page at the text/data boundary, even

When we have CONFIG_STRICT_KERNEL_RWX enabled, we want to split the

But the current logic uses small pages for the entire text section,
regardless of whether a larger page size would fit. eg. with the
boundary at
If we look closely at the logic in create_physical_mapping(), when
we're doing STRICT_KERNEL_RWX, we do the following steps:
- determine the gap from where we are to the end of the range
- choose an appropriate mapping_size based on the gap
- check if that mapping_size would overlap the
At boot we print the ranges we've mapped for the linear mapping and
what page size we've used. Also track whether the range is mapped
executable or not and display that as well.
