Content-Type: text/plain; charset=ISO-8859-1; format=flowed List-Id: Linux on PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi all, I've got a ppc64 box running 2.6.14. 64-bit kernel, 32-bit userspace. It has a ~86KB chunk of memory near the top of the process address space, and I'm not sure who's setting it up and what the purpose is. In /proc//maps it looks like this: fffea000-fffff000 rw-p fffea000 00:00 0 Can anyone enlighten me as to what this is for and who is allocating it? Thanks, Chris
