fpurestore() unconditionally changed fpstate to FPinactive when the kernel used the FPU. but in the FPinit case, the registers are not saved by mathemu(), resulting in all zero initialized registers being loaded once userspace uses the FPU so the process would have wrong MXCR value. the index overflow check was wrong with using shifted value. |
