Ralf Baechle 51d943f07d MIPS: Fix for warning from FPU emulation code ... The default implementation of 'cpu_has_fpu' macro calls smp_processor_id() which causes this warning to be printed when preemption is enabled: [ 4.664000] Algorithmics/MIPS FPU Emulator v1.5 [ 4.676000] BUG: using smp_processor_id() in preemptible [00000000] code: ini [ 4.700000] caller is fpu_emulator_cop1Handler+0x434/0x27b8 This problem got introduced in November 2009 by af1d2af877ef6c36990671bc86a5b9c5bb50b1da (lmo) [MIPS: Fix emulation of 64-bit FPU on 64-bit CPUs.] rsp. da0bac3341 (kernel.org) [MIPS: Fix emulation of 64-bit FPU on FPU-less 64-bit CPUs.] in 2.6.32. Fixed by rewriting cop1_64bit() to return a constant whenever possible but most importantly avoid the use pf cpu_has_fpu entirely.
