      [PARTITION] MSDOS: Fix Sun num_partitions handling. · b84d8796
      由 Mark Fortescue 提交于 
      Correct the Solaris x86 number of partitions (slices) is a way that is
backward compatible with the earlier size.

This works without a new VTOC structure definition as the timestamp
and v_asciilabel fields in the VTOC are not used by the kernel yet.

      Remove fs.h from mm.h · 4e950f6f
      由 Alexey Dobriyan 提交于 
      Remove fs.h from mm.h. For this,
 1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
 2) Add back fs.h or less bloated headers (err.h) to files that need it.

As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
rebuilt down to 3444 (-12.3%).

Cross-compile tested without regressions on my two usual configs and (sigh):

      Introduce CONFIG_SUSPEND for suspend-to-Ram and standby · 296699de
      由 Rafael J. Wysocki 提交于 
      Introduce CONFIG_SUSPEND representing the ability to enter system sleep
states, such as the ACPI S3 state, and allow the user to choose SUSPEND
and HIBERNATION independently of each other.

Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
been chosen and the kernel is intended for SMP systems.

Also, introduce CONFIG_PM_SLEEP which is automatically selected if
CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
code needed for both suspend and hibernation.

The top-level power management headers and the ACPI code related to
suspend and hibernation are modified to use the new definitions (the
changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
the number of ifdefs).

There are many other files in which CONFIG_PM can be replaced with
CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
the future.

      [PATCH] sched: add above_background_load() function · d02c7a8c
      由 Con Kolivas 提交于 
      Add an above_background_load() function which can be used by other
subsystems to detect if there is anything besides niced tasks running.

Place it in sched.h to allow it to be compiled out if not used.

Unused for now, but it is a useful hint to the IO scheduler and to
swap-prefetch.

      [PATCH] sched: increase SCHED_LOAD_SCALE_FUZZ · b47e8608
      由 Ingo Molnar 提交于 
      increase SCHED_LOAD_SCALE_FUZZ that adds a small amount of
over-balancing: to help distribute CPU-bound tasks more fairly on SMP
systems.

the problem of unfair balancing was noticed and reported by Tong N Li.

so they now nicely converge to the expected 80% long-term CPU usage.
