Merge branch 'unicore32' of git://git.kernel.org/pub/scm/linux/kernel/git/epip/linux-2.6-unicore32
* 'unicore32' of git://git.kernel.org/pub/scm/linux/kernel/git/epip/linux-2.6-unicore32: unicore32: using generic-y format for one line asm-generic files unicore32: change PERCPU to PERCPU_SECTION unicore32: add KBUILD_DEFCONFIG with unicore32_defconfig (old debug_defconfig) unicore32: change zImage physical address, though it's PIC codes unicore32: move rtc-puv3.c to drivers/rtc directory
