[PATCH 4/9] namespaces: utsname: switch to using uts namespaces

From: Serge E. Hallyn
Date: Thu May 18 2006 - 11:49:16 EST

Replace references to system_utsname to the per-process uts namespace
where appropriate. This includes things like uname.

Changes: Per Eric Biederman's comments, use the per-process uts namespace
for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c
