b18bf0948e x86, apic: Include module.h header in apic_flat_64.c
apic_flat_64.c needs to include module.h because it uses
EXPORT_SYMBOL_GPL().

This fixes these warnings on some !SMP randconfigs:

  arch/x86/kernel/apic/apic_flat_64.c:31: warning: data definition has no type or storage class
  arch/x86/kernel/apic/apic_flat_64.c:31: warning: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL'
  arch/x86/kernel/apic/apic_flat_64.c:31: warning: parameter names (without types) in function declaration

bb74e8ca35 hwmon: (coretemp) Fix compile error if CONFIG_SMP is not defined
cpu_sibling_mask() is not defined unless CONFIG_SMP is defined, so it
must not be used directly in the code without ifdef protection.

To solve the problem and avoid ifdefs in the code, define
for_each_sibling() and use it instead.

ff2a9941ca block: move bd_set_size() above rescan_partitions() in __blkdev_get()
02e352287a (block: rescan partitions on invalidated devices on
-ENOMEDIA too) relocated partition rescan above explicit bd_set_size()
to simplify condition check.  As rescan_partitions() does its own bdev
size setting, this doesn't break anything; however,
rescan_partitions() prints out the following messages when adjusting
bdev size, which can be confusing.

  sda: detected capacity change from 0 to 146815737856
  sdb: detected capacity change from 0 to 146815737856

This patch restores the original order and remove the warning
messages.

stable: Please apply together with 02e352287a (block: rescan
        partitions on invalidated devices on -ENOMEDIA too).

68fa61c026 hrtimers: Reorder clock bases
The ordering of the clock bases is historical due to the
CLOCK_REALTIME and CLOCK_MONOTONIC constants. Now the hrtimer bases
have their own enumeration due to the gap between CLOCK_MONOTONIC and
CLOCK_BOOTTIME. So we can be more clever as most timers end up on the
CLOCK_MONOTONIC base due to the virtue of POSIX declaring that
relative CLOCK_REALTIME timers are not affected by time changes. In
desktop environments this is slowly changing as applications switch to
absolute timers, but I've observed empty CLOCK_REALTIME bases often
enough. There is no performance penalty or overhead when
CLOCK_REALTIME timers are active, but in case they are not we don't
skip over a full cache line.

f24444b01b hrtimers: Make struct hrtimer_cpu_base layout less stupid
In the HIGHRES=y case we access the members at the end of struct
hrtimer_cpu_base first and then the one at the beginning. Move the
hrtimer data to front, so we have linear progressing access.

9ec2690758 timerfd: Manage cancelable timers in timerfd
Peter is concerned about the extra scan of CLOCK_REALTIME_COS in the
timer interrupt. Yes, I did not think about it, because the solution
was so elegant. I didn't like the extra list in timerfd when it was
proposed some time ago, but with a rcu based list the list walk it's
less horrible than the original global lock, which was held over the
list iteration.
