The following commits:
7094e6acaf7a ("riscv: Simplify xip and !xip kernel address conversion macros") 9b79878ced8f ("riscv: Remove CONFIG_PHYS_RAM_BASE_FIXED")
expose CONFIG_PHYS_RAM_BASE for all kernel types whereas this value is implementation-specific, so that breaks the kernel genericity.
The first patch in this patchset removes the usage of CONFIG_PHYS_RAM_BASE by introducing a new global variable that holds this value.
The second patch reverts 9b79878ced8f ("riscv: Remove CONFIG_PHYS_RAM_BASE_FIXED").
The last patch is an optimization 'symmetrical' to the one introduced in the first patch: this is not a fix, then it is not necessary to pull this into -fixes.
Alexandre Ghiti (3): riscv: Get rid of CONFIG_PHYS_RAM_BASE in kernel physical address conversion Revert "riscv: Remove CONFIG_PHYS_RAM_BASE_FIXED" riscv: Optimize kernel virtual address conversion macro
