# NOTE: we SHOULD be using at least binutils 2.15.90.0.1 everywhere for proper
# .eh_frame ld optimisation and symbol visibility support, but it hasnt been
# well tested in gentoo on any arch other than amd64!!

# 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,
# 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
# this patch does, because if you are, you are probably already aware of what
# it does.
# All that said, the abilities of this patch are disabled by default and need
# to be enabled by passing -mip28-cache-barrier. Only used to build kernels,
# There is the possibility it may be used for very specific userland apps too.
