# 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!!

			# 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.
