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.

ARM: EXYNOS: Add support AFTR mode on EXYNOS4210
ARM: SAMSUNG: use spin_lock_irqsave() in clk_{enable,disable}
ARM: S3C64XX: Define some additional always off clocks
ARM: S3C64XX: Reduce residency requirement for cpuidle WFI mode

ARM: SAMSUNG: add G2D to plat-s5p and mach-exynos
ARM: S3C64XX: Gate some more clocks by default
ARM: S3C64XX: Add basic cpuidle driver
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.

Commit f0fbf0abc0 ("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.

suspend/resume is used and the compiler has not inlined the
