Subject: [PATCH 1/2] powerpc/vmlinux.lds: Move _edata down
Date: Mon, 10 Aug 2009 15:06:24 +1000 (EST) [thread overview]
Message-ID: <ab02e115992881a734e8e90b7d3f2d8617db4bf2.1249880775.git.michael@ellerman.id.au> (raw)
Currently _edata does not include several data sections, this causes
the kernel's report of memory usage at boot to not match reality, and
also prevents kmemleak from working - because it scan between _sdata
and _edata for pointers to allocated memory.
This mirrors a similar change made recently to the x86 linker script.
