My primary target now is create stable kernel for both Android and Maemo. I'm trying to create minimalistic Android patchset for applying to kernel-omap1 or kernel-power. quilt is very useful in that task.
Current progress:
user@maemo-sdk:~/kernel.power$ quilt files
drivers/misc/Kconfig
drivers/misc/Makefile
drivers/misc/pmem.c
drivers/rtc/Kconfig
drivers/rtc/Makefile
drivers/rtc/alarm.c
drivers/staging/Kconfig
drivers/staging/Makefile
drivers/staging/android/Kconfig
drivers/staging/android/Makefile
drivers/staging/android/binder.c
drivers/staging/android/binder.h
drivers/staging/android/logger.c
drivers/staging/android/logger.h
drivers/staging/android/lowmemorykiller.c
drivers/staging/android/ram_console.c
drivers/staging/android/timed_gpio.c
drivers/staging/android/timed_gpio.h
drivers/staging/android/timed_output.c
drivers/staging/android/timed_output.h
include/linux/android_aid.h
include/linux/android_alarm.h
include/linux/android_pmem.h
include/linux/ashmem.h
init/Kconfig
mm/Makefile
mm/ashmem.c

I plan to test new kernel patch and upload it and rootfs (which I promised upload today. sorry) as it will be done.

wifi, sound etc. has to be solved. once primary target will be achieved.
