From: Matt Fleming <matt.fleming at intel.com> The following patch series is available at, git://git.zytor.com/users/mfleming/syslinux.git elflink All patches are against the 'elflink' branch. This series fixes a few serious bugs and some behavioural incompatibilities with the 4.x series. Matt Fleming (19): ldlinux: Initialise 'p' before using it. ldlinux: Parse

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. The config file parsing

From: Matt Fleming <matt.fleming at linux.intel.com> These patches are based on the elflink branch. This set of patches is my attempt at moving the command-line interface functionality out of the core and into an ELF module to reduce the size of the core. The most interesting patch is [PATCH 4/4] which moves the cli code out of core/elflink and into com32/elflink/modules. [PATCH 4/4] is

From: Matt Fleming <matt.fleming at intel.com> Since we can't use __intcall() for EFI, and since we can now have the ELF module code resolve all our symbols at runtime, we should delete as many references to __intcall() as possible and just access the symbols directly. The most interesting patch is the support for weak symbols. We need to be able to reference derivative-specific

From: Matt Fleming <matt.fleming at linux.intel.com> This series fixes some bugs and switches the elflink branch to be entirely ELF modules. It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!). Now there should be no duplicate code because we don't need COM32 and
