Subject: perf machine: Set kernel data mapping length
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4552cf0f774ae3d24bf31e91324586274a552a66;p=openwrt%2Fstaging%2Fblogic.git

perf machine: Set kernel data mapping length

Currently only text (function) mapping was set, so that the kernel data
addresses couldn't parsed correctly.  Fix it.
