Hi Linus, Today's linux-next build (x86_64 allmodconfig) failed like this: drivers/rtc/rtc-m48t35.c: In function 'm48t35_read_time': drivers/rtc/rtc-m48t35.c:59: error: implicit declaration of function 'readb' drivers/rtc/rtc-m48t35.c:60: error: implicit declaration of function 'writeb' drivers/rtc/rtc-m48t35.c: In function 'm48t35_probe': drivers/rtc/rtc-m48t35.c:168: error: implicit declaration of function 'ioremap' drivers/rtc/rtc-m48t35.c:168: warning: assignment makes pointer from integer without a cast drivers/rtc/rtc-m48t35.c:188: error: implicit declaration of function 'iounmap' Caused by commit d1dbd82e2ff02181a7102088a9fe83e17ddbcb47 ("RTC: M48T35: new RTC driver") which also presumably should depend on some architecture or feature. I have reverted it for now. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
