X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=59f2e69d0f95bc00353628ef33fd534fbb8e3597;p=linux-2.6-omap-h63xx.git [S390] zfcpdump: Prevent zcore from beeing built as a kernel module. The zcore code switches to real addressing mode when creating a kernel dump. This is not possible, if it is built as a kernel module. With this patch zcore (zfcpdump) can't be built as a kernel module any more.
