mips: LOONGSON32: drop a dangling Kconfig symbol

2026-02-26T23:01:26Z

[ Upstream commit d463fc5ca1ace0b2e8bb764df04fc12ecd6f8e2b ] CPU_HAS_LOAD_STORE_LR is not used anywhere in the kernel sources, so drop it.

MIPS: Fix HOTPLUG_PARALLEL dependency

2025-12-01T09:04:21Z

With MIPS, it is possible to have SMP enabled without HOTPLUG_CPU selected. However, in kernel/cpu.c, some code that uses HOTPLUG_PARALLEL also requires HOTPLUG_CPU to be selected. Therefore, we should fix the HOTPLUG_PARALLEL dependency to depend on HOTPLUG_CPU, not just SMP.

MIPS: loongson32: Switch to generic core

2025-08-29T20:34:31Z

The generic MIPS core is fully compatible with Loongson-1 SoCs, so migrate Loongson-1 to it. Main changes are: - Merge CPU_LOONGSON1B and CPU_LOONGSON1C into a unified CPU_LOONGSON32, as both are based on the GS232 core. - Consolidate LOONGSON1_LS1B and LOONGSON1_LS1C Kconfig options into MACH_LOONGSON32. - Enable MACH_GENERIC_CORE and remove the legacy custom implementation. - Remove all Loongson-1 platform devices and associated code, which are now obsolete due to Device Tree support. - Misc cleanup.

mips: Unconditionally select ARCH_HAS_CURRENT_STACK_POINTER

Now that the minimum supported version of LLVM for building the kernel has been bumped to 15.0.0, the selection of ARCH_HAS_CURRENT_STACK_POINTER can be made unconditional since it is always true.
