Peter Anvin <hpa at linux.intel.com> CommitDate: Tue, 15 Apr 2014 13:23:49 -0700 readlink: Reduce size by calling _fwrite() instead of puts() We know how long the output is, so we might as well call _fwrite() directly, with the explicit termination set to \n instead of \0.

From: Matt Fleming <matt.fleming at linux.intel.com> This is a series of patches that, * shrink the core by moving things into an ldlinux ELF module * begin wiring up some of the C versions of various functions The core now only contains essential code and loads the ldlinux module to do everything else, like providing a command line interface and loading kernels.
