Subject: [IA64] ensure XPC and XPNET are loaded on sn2 platforms only
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=408865ce4829376120489ac8011b72125453dcff;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[IA64] ensure XPC and XPNET are loaded on sn2 platforms only

These are SN2 only drivers.  They should have platform checks to prevent
them from doing evil stuff in GENERIC kernels.
