While building the Malta defconfig, sparse spat the following warnings: >>>>>>>>>>>>>>>>>> arch/mips/math-emu/kernel_linkage.c:31:6: warning: symbol 'fpu_emulator_init_fpu' was not declared. Should it be static? arch/mips/math-emu/kernel_linkage.c:54:5: warning: symbol 'fpu_emulator_save_context' was not declared. Should it be static? arch/mips/math-emu/kernel_linkage.c:68:5: warning: symbol 'fpu_emulator_restore_context' was not declared. Should it be static? >>>>>>>>>>>>>>>>>> This patch fixes these errors by adding the proper prototypes to the include/asm-mips/fpu.h header, and actually using this header in the sparse-spotted source file. Build-tested with Malta defconfig.
