Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: Blackfin arch: fix a broken define in dma-mapping Blackfin arch: fix bug - Turn on DEBUG_DOUBLEFAULT, booting SMP kernel crash Blackfin arch: fix bug - shared lib function in L2 failed be called Blackfin arch: fix incorrect limit check for bf54x check_gpio Blackfin arch: fix bug - Cpufreq assumes clocks in kHz and not Hz. Blackfin arch: dont warn when running a kernel on the oldest supported silicon Blackfin arch: fix bug - kernel build with write back policy fails to be booted up Blackfin arch: fix bug - dmacopy test case fail on all platform Blackfin arch: Fix typo when adding CONFIG_DEBUG_VERBOSE Blackfin arch: don't copy bss when copying L1 Blackfin arch: fix bug - Fail to boot jffs2 kernel for BF561 with SMP patch Blackfin arch: handle case of d_path() returning error in decode_address()
