Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote). Upstream: https://github.com/xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2)

* Because of the wide memory address space between physical RAM banks on the

|
* our memory map representation. Assuming all memory nodes have equal access
|
|
* characteristics, we then have generic discontiguous memory support.
|
|
*
|
|
* The sparsemem banks are matched with the physical memory bank addresses
|
|
