Huacai Chen 95c5d3fbd3 LoongArch: Ensure FP/SIMD registers in the core dump file is up to date ... [ Upstream commit 656f9aec07 ] This is a port of commit 379eb01c21 ("riscv: Ensure the value of FP registers in the core dump file is up to date"). The values of FP/SIMD registers in the core dump file come from the thread.fpu. However, kernel saves the FP/SIMD registers only before scheduling out the process. If no process switch happens during the exception handling, kernel will not have a chance to save the latest values of FP/SIMD registers. So it may cause their values in the core dump file incorrect. To solve this problem, force fpr_get()/simd_get() to save the FP/SIMD registers into the thread.fpu if the target task equals the current task.
