As part of the Radix MMU support we added some feature sections in the
SLB miss handler. These are intended to catch the case that we
incorrectly take an SLB miss when Radix is enabled, and instead of
crashing weirdly they bail out to a well defined exit path and trigger
an oops.

However the way they were written meant the bailout case was enabled by
default until we did CPU feature patching.

On powermacs the early debug prints in setup_system() can cause an SLB
miss, which happens before code patching, and so the SLB miss handler
would incorrectly bailout and crash during boot.

Fix it by inverting the sense of the feature section, so that the code
which is in place at boot is correct for the hash case. Once we
determine we are using Radix - which will never happen on a powermac -
only then do we patch in the bailout case which unconditionally jumps.

Description: tail replacement using inotify
 inotail is a replacement for the 'tail' program which is used to output the
 last portions of a file. It makes use of the inotify infrastructure in recent
 versions of the Linux kernel to speed up tailing files in the follow
 mode (the '-f' option). Ancient versions of tail poll the file every second by
 default while inotail (and tail from the GNU coreutils as of version 7.5)
 listens to special events sent by the kernel through the inotify API to
 determine whether a file needs to be reread.
