# This is a very special patch -- it allows us to build semi-usable kernels |

# on SGI IP28 (Indigo2 Impact R10000) systems. The patch is henceforth |

# regarded as a kludge by upstream, and thus, it will never get accepted upstream, |
| 66 |
# but for our purposes of building a kernel, it works. |

# Unless you're building an IP28 kernel, you really don't need care about what |
| 68 |
# this patch does, because if you are, you are probably already aware of what |
| 69 |
# it does. |
| 70 |
# All that said, the abilities of this patch are disabled by default and need |
| 71 |
# to be enabled by passing -mip28-cache-barrier. Only used to build kernels, |
| 72 |
# There is the possibility it may be used for very specific userland apps too. |
