(Actually, do we know which commit broke the ordering? We may want to
simply revert that one...)
BTW I'm currently trying to set-up automated scripts for n900/qemu
testing. I guess I'll try to run them on mainline kernel to catch such
stuff earlier.
One thing I'd like to know: how do you configure kernel to get output
on qemu? I was doing CONFIG_DEBUG_LL with specific uart, but that
needed patching the kernel, you apparently have something more clever.
I tried doing:
# CONFIG_DEBUG_LL is not set
CONFIG_DEBUG_LL_INCLUDE="mach/debug-macro.S"
CONFIG_UNCOMPRESS_INCLUDE="debug/uncompress.h"
but no output on console...
Thanks,
Pavel
