X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=db7e826030dc6775b862468476c1fd08b10f0799;p=thirdparty%2Fkernel%2Flinux.git

parisc: Enhance debug code for PAT firmware

Enhance output when running PAT firmware, which is helpful when
developing the QEMU emulator. The added code is behind an ifdef,
so no performance overhead for normal kernels.
