2012-03-14ARM: shmobile: remove additional __io() macro useArnd Bergmann1-1/+1
setup-r8a7779.c has grown a new user of the __io() macro. Rob Herring's PIO cleanup series already gets rid of all other uses in shmobile, so we should ensure that this one gets removed as well. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

2012-03-10ARM: EXYNOS: fix cycle count for periodic mode of clock event timersChanghwan Youn1-8/+13
EXYNOS SOC series use MCT for kernel timer and MCT has two types of clock event timers, which are mct-comp and mct-tick. Because the clock rate of each event timer is diffent from the other, this patch fixes cycles_per_jiffy for each timer's periodic mode.

2012-03-10x86: Derandom delay_tsc for 64 bitThomas Gleixner1-2/+2
Commit f0fbf0abc093 ("x86: integrate delay functions") converted delay_tsc() into a random delay generator for 64 bit. The reason is that it merged the mostly identical versions of delay_32.c and delay_64.c. Though the subtle difference of the result was: static void delay_tsc(unsigned long loops) { - unsigned bclock, now; + unsigned long bclock, now; Now the function uses rdtscl() which returns the lower 32bit of the TSC. On 32bit that's not problematic as unsigned long is 32bit. On 64 bit this fails when the lower 32bit are close to wrap around when bclock is read, because the following check if ((now - bclock) >= loops) break; evaluated to true on 64bit for e.g. bclock = 0xffffffff and now = 0 because the unsigned long (now - bclock) of these values results in 0xffffffff00000001 which is definitely larger than the loops value. That explains Tvortkos observation: "Because I am seeing udelay(500) (_occasionally_) being short, and that by delaying for some duration between 0us (yep) and 491us." Make those variables explicitely u32 again, so this works for both 32 and 64 bit.

2012-03-09ARM: SAMSUNG: Add __init attribute to samsung_bl_set()Tushar Behera1-1/+1
s3c_set_platdata() is defined with __init attribute, hence all functions referencing this function should also be defined with __init attribute. samsung_bl_set() is referenced only in '__init xxx_machine_init()' functions, thus this change won't put any additional constraint on the usage of samsung_bl_set().
