[PATCH v2 0/3] System-wide tunables

[DJ Delorie]

This patch series is the initial implementation of system-wide
tunables, which I mentioned a few months ago.

The first part has ldconfig read tunable information from
/etc/tunables.conf and store it to /etc/ld.so.cache.  Reusing ldconfig
means no new documentation or training would be required of sysadmins,
or reprogramming of distro packaging.

The second part optimizes the loading of /etc/ld.so.cache and allows
for it to be loaded independently of searching for libraries.

The third part applies the stored tunable information to the running
application.

Changes since v1: fixed format bug in error() and rebased.  No other
  changes.

DJ Delorie (3):
  Add system-wide tunables: ldconfig part
  Add system-wide tunables: cache ld.so.cache
  Add system-wide tunables: Apply tunables part
