The generic SMP kernel update for Slackware 12.2 was built using the
.config for a huge kernel, not a generic one. The kernel previously
published as kernel-generic-smp and in the gemsmp.s directory works
and is secure, but is larger than it needs to be. It has been
replaced in the Slackware 12.2 patches with a generic SMP kernel.

A new svgalib_helper package (compiled for a 2.6.27.31 kernel) was
added to the Slackware 12.2 /patches.

An error was noticed in the SSA:2009-230-01 advisory concerning the
packages for Slackware -current 32-bit. The http links given refer to
packages with a -1 build version. The actual packages have a build
number of -2.


Here are the details from the Slackware 12.2 ChangeLog:
+--------------------------+
patches/packages/linux-2.6.27.31/kernel-modules-smp-2.6.27.31_smp-i686-2.tgz:
 Rebuilt the modules using the config-generic-smp-2.6.27.31-smp .config.
patches/packages/linux-2.6.27.31/kernel-generic-smp-2.6.27.31_smp-i686-2.tgz:
 Fixed the .config to use config-generic-smp-2.6.27.31-smp.
 The config-generic-huge-2.6.27.31-smp was mistakenly used for build -1.
 Thanks to Chuck56 for the report.
patches/packages/linux-2.6.27.31/kernel-source-2.6.27.31_smp-noarch-2.tgz:
 Changed the included .config to the config-generic-smp-2.6.27.31-smp version.
patches/packages/svgalib_helper-1.9.25_2.6.27.31-i486-1_slack12.2.tgz:
 Recompiled for 2.6.27.31.
