Hi Ingo,
A bunch of fixes that I dropped the ball on back in 3.7.
Mostly compilation fixes for errors that have happened
due to changes on the kernel side in 3.7.
Ben Hutchings (7):
liblockdep: Fix undefined symbol prandom_u32
liblockdep: Reduce MAX_LOCK_DEPTH to avoid overflowing
lock_chain::depth
liblockdep: Define the ARRAY_SIZE() macro
liblockdep: Enable -Wall by default
liblockdep: Fix 'unused value' warnings
liblockdep: Fix 'set but not used' warnings
liblockdep: Fix 'defined but not used' warning for init_utsname()
Vishal Thanki (1):
liblockdep: Remove -lpthread compiler option

__lock_pin_lock() now calls prandom_u32() which is not defined in
liblockdep. __lock_pin_lock() and its caller lock_pin_lock() are dead
code in liblockdep, but we still need to provide a definition of
prandom_u32() in case lazy binding is disabled.
