Ioannis Glaropoulos 4f4b23b449 arch: arm: fp sharing: save & restore FP registers in context-switch ... When in Sharing Floating Point Services mode we want to dynamically save and restore the FP registers in thread context switch, depending on whether the swapped-in and swapped-out threads are currently using the FP registers. This commit adds this functionality to the ARM context switch mechanism. The logic consists of inspecting the corresponding status flag (present in thread.arch.mode) to decide whether to save or restore the FP registers.
