It appears you are applying the patch to an Android or other third-party
derivative of Linux, instead of Linux proper, or that either the kernel
or the patch you have fetched is corrupt.  Try re-fetching everything and
try again.  This sequence works for me:

   cd
   mkdir junk
   cd junk
   wget -q ftp://ftp.kernel.org/pub/linux/kernel/v3.0/linux-3.18.11.tar.xz
   wget -q ftp://ftp.kernel.org/pub/linux/kernel/projects/rt/3.18/patch-3.18.13-rt10.patch.xz
   tar xf l*xz
   cd linux*11
   unxz <../pat*xz | patch -p1

There are some (annoying) offset errors, but no fuzzies or rejects like you have
been seeing.
