## Oops Code

```
Oops: 0002 [#1] PREEMPT SMP
```

This is the error code value in hex. Each bit has a significance of its own:
- bit 0 == 0 means no page found, 1 means a protection fault
- bit 1 == 0 means read, 1 means write
- bit 2 == 0 means kernel, 1 means user-mode

/* fix_fft.c - Fixed-point in-place Fast Fourier Transform  */
/*
  All data are fixed-point short integers, in which -32768
  to +32768 represent -1.0 to +1.0 respectively. Integer
  arithmetic is used for speed, instead of the more natural
  floating-point.

  For the forward FFT (time -> freq), fixed scaling is
  performed to prevent arithmetic overflow, and to map a 0dB
  sine/cosine wave (i.e. amplitude = 32767) to two -6dB freq
