Subject: x86: correctly wire up the newuname system call
From: Christoph Hellwig <hch@xxxxxx>
Before commit e28cbf22933d0c0ccaf3c4c27a1a263b41f73859 ("improve
sys_newuname() for compat architectures") 64-bit x86 had a private
implementation of sys_uname which was just called sys_uname, which other
architectures used for the old uname. Due to some merge issues with the
uname refactoring patches we ended up calling the old uname version for
both the old and new system call slots, which lead to the domainname filed
never be set which caused failures with libnss_nis.
