What: lock_policy_rwsem_* and unlock_policy_rwsem_* will not be
exported interface anymore.
When: 2.6.33
Why: cpu_policy_rwsem has a new cleaner definition making it local to
cpufreq core and contained inside cpufreq.c. Other dependent
drivers should not use it in order to safely avoid lockdep issues.

Problem: Files copied from sysfs appear empty or incomplete.
Cause: Due to the way seq_file works, some tools such as cp or tar
may not correctly copy files from sysfs.
Solution: Use 'cat' to read .gcda files and 'cp -d' to copy links.
Alternatively use the mechanism shown in Appendix B.

Kmemleak can also be disabled at boot-time by passing "kmemleak=off" on

Memory may be allocated or freed before kmemleak is initialised and
these actions are stored in an early log buffer. The size of this buffer
is configured via the CONFIG_DEBUG_KMEMLEAK_EARLY_LOG_SIZE option.
