[svn-commits] tzafrir: branch 1.4 r3076 - /branches/1.4/Makefile.kernel26

[SVN commits to the Digium repositories]

Author: tzafrir
Date: Sat Sep 22 03:07:27 2007
New Revision: 3076

URL: http://svn.digium.com/view/zaptel?view=rev&rev=3076
Log:
Makefile Automatically enabling Zaptel MMX support. Disabled by default
for now.
* To enable, build with ZAPTEL_MMX_AUTO=yes (or any other non-empty
  value)
* There is a white list of configuration values (without the prefix 
  CONFIG_). One of them needs to be set in order for CONFIG_ZAPTEL_MMX
  to be enabled.
* Only adds support for kernel 2.6 . If anybody finds a simple way to do
  the same with 2.4 - patches are welcomes.
