Introduce the kernel_fpu_begin() and kernel_fpu_end() function to enclose any in-kernel use of FPU instructions and registers. In enclosed sections, you can perform floating-point or vector (SIMD) computations. The functions take care of saving and restoring FPU register contents and controls. For usage details, see the guidelines in arch/s390/include/asm/fpu/api.h Signed-off-by: Hendrik Brueckner <brueckner@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> |
