[PATCH 00/20] Switch to ELF modules
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

[PATCH 0/5] Deleting __intcall() from Syslinux
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

[PATCH 00/21] Upgrade to Lua 5.2.2, add filesystem module and get_key binding
Hi,
This series targets automatic boot menu generation, but most of it
is the Lua upgrade, because I got tired reading deprecated API docs.
It's mostly a straightforward forward port of the earlier Syslinux
specific changes to Lua 5.1, except that:
* I chose the add a stub getenv() implementation to the COM32 API
instead of #ifdefing out all the references in Lua, and
* I kept oslib
