See patch below. Remove unused function 'mf_getSrcHistory' (that will never be used ever according to Stephen Rothwell) and also remove most of (under 'if 0') code from mf_src_proc_show() where the function was called.

Hi, We can get rid of a memset in arch/powerpc/platforms/cell/spufs/lscsa_alloc.c::spu_alloc_lscsa_std() by using vzalloc() rather than vmalloc()+memset().

Create sysfs interface to export data from H_BEST_ENERGY hcall that can be used by administrative tools on supported pseries platforms for energy management optimizations. sys/device/system/cpu/pseries_(de)activate_hint_list and sys/device/system/cpu/cpuN/pseries_(de)activate_hint will provide hints for activation and deactivation of cpus respectively. These hints are abstract number given by the hypervisor based on the extended knowledge the hypervisor has regarding the system topology and resource mappings. The activate and the deactivate sysfs entry is for the two distinct operations that we could do for energy savings. When we have more capacity than required, we could deactivate few core to save energy. The choice of the core to deactivate will be based on /sys/devices/system/cpu/deactivate_hint_list. The comma separated list of cpus (cores) will be the preferred choice. If we have to activate some of the deactivated cores, then /sys/devices/system/cpu/activate_hint_list will be used. The per-cpu file /sys/device/system/cpu/cpuN/pseries_(de)activate_hint further provide more fine grain information by exporting the value of the hint itself.

These APIs take logical cpu number as input Change cpu_first_thread_in_core() to cpu_first_thread_sibling() Change cpu_last_thread_in_core() to cpu_last_thread_sibling() These APIs convert core number (index) to logical cpu/thread numbers Add cpu_first_thread_of_core(int core) Changed cpu_thread_to_core() to cpu_core_index_of_thread(int cpu) The goal is to make 'threads_per_core' accessible to the pseries_energy module. Instead of making an API to read threads_per_core, this is a higher level wrapper function to convert from logical cpu number to core number. The current APIs cpu_first_thread_in_core() and cpu_last_thread_in_core() returns logical CPU number while cpu_thread_to_core() returns core number or index which is not a logical CPU number. The new APIs are now clearly named to distinguish 'core number' versus first and last 'logical cpu number' in that core. The new APIs cpu_{first,last}_thread_sibling() work on logical cpu numbers. While cpu_first_thread_of_core() and cpu_core_index_of_thread() work on core index. Example usage: (4 threads per core system) cpu_first_thread_sibling(5) = 4 cpu_last_thread_sibling(5) = 7 cpu_core_index_of_thread(5) = 1 cpu_first_thread_of_core(1) = 4 cpu_core_index_of_thread() is used in cpu_to_drc_index() in the module and cpu_first_thread_of_core() is used in drc_index_to_cpu() in the module. Make API changes to few callers. Export symbols for use in modules.

POWER5 added popcntb, and POWER7 added popcntw and popcntd. As a first step this patch does all the work out of line, but it would be nice to implement them as inlines with an out of line fallback. The performance issue with hweight was noticed when disabling SMT on a large (192 thread) POWER7 box. The patch improves that testcase by about 8%.

And in particular, use it in 'pipe_fcntl()'. The other pipe functions do not need to use the 'careful' version, since they are only ever called for things that are already known to be pipes. The normal read/write/ioctl functions are called through the file operations structures, so if a file isn't a pipe, they'd never get called. But pipe_fcntl() is special, and called directly from the generic fcntl code, and needs to use the same careful function that the splice code is using.

.. and change it to take the 'file' pointer instead of an inode, since that's what all users want anyway. The renaming is preparatory to exporting it to other users. The old 'pipe_info()' name was too generic and is already used elsewhere, so before making the function public we need to use a more specific name.
