When merged to Linus's latest tree the perf build is broken
due to following change in lib/rbtree.c object:

  lib: reduce the use of module.h wherever possible
  commit 8bc3bcc93a2b4e47d5d410146f6546bca6171663
  Author: Paul Gortmaker <paul.gortmaker@windriver.com>
  Date:   Wed Nov 16 21:29:17 2011 -0500

We need to move module.h header into export.h.

This renames for_each_set_bit_cont() to for_each_set_bit_from() because
it is analogous to list_for_each_entry_from() in list.h rather than
list_for_each_entry_continue().

This doesn't remove for_each_set_bit_cont() for now.

Adding implementation os bitmap_or function to the bitmap object. It is
stolen from the kernel lib/bitmap.o object.

It is used in upcomming patches.

This patch introduces the for_each_set_bit() macro and modifies feature
implementation to use it.

Upstream glibc commit 295e904 added a definition for __attribute_const__
to cdefs.h.  This causes the following error when building perf:

util/include/linux/compiler.h:8:0: error: "__attribute_const__"
redefined [-Werror] /usr/include/sys/cdefs.h:226:0: note: this is the
location of the previous definition

Wrap __attribute_const__ in #ifndef as we do for __always_inline.

Commit e66eed651fd1 ("list: remove prefetching from regular list
iterators") removed the include of prefetch.h from list.h, which
uncovered several cases that had apparently relied on that rather
obscure header file dependency.

So this fixes things up a bit, using

   grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]')
   grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]')

to guide us in finding files that either need <linux/prefetch.h>
inclusion, or have it despite not needing it.

There are more of them around (mostly network drivers), but this gets
many core ones.

Killing two more perf wide global variables: nr_counters and evsel_list
as a list_head.

There are more operations that will need more fields in perf_evlist,
like the pollfd for polling all the fds in a list of evsel instances.

Use option->value to pass the evsel_list to parse_{events,filters}.
