From: Gerald Schaefer Date: Wed, 20 Sep 2006 13:59:26 +0000 (+0200) Subject: [S390] cleanup appldata. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1f38d61347203055b55e34083cce7a9cd8c529a9;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git [S390] cleanup appldata. Introduce asm header that contains the appldata data structures and the diag inline assembly.
