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)

* This is based on the T13 group document D1572 Revision 0 (August 14 2002)
|
|
* available at http://www.t13.org/docs2002/d1572r0.pdf. It is

|
|
* In a nutshell, arch/{i386,x86_64}/boot/setup.S populates a scratch
|
|
* table in the boot_params that contains a list of BIOS-enumerated
|
|
* boot devices.
|
|
* In arch/{i386,x86_64}/kernel/setup.c, this information is
|
|
* transferred into the edd structure, and in drivers/firmware/edd.c, that
|
|
* information is used to identify BIOS boot disk. The code in setup.S
|
|
* is very sensitive to the size of these structures.
