Commit 818b667ba57f68bf1e7240fa441dda0b11e6b944

Authored by Stephen Boyd
Committed by Linus Torvalds
1 parent 21b7d815b2
Exists in master and in 4 other branches v3.2_AM335xPSP_04.06.00.11, v3.2_NEWT335xPSP_04.06.00.11, v3.2_SBC_SMARTMEN, v3.2_SMARCT335xPSP_04.06.00.11

Remove unused PROC_CHANGE_PENALTY constant 

This constant hasn't been used since before the git era (2.6.12) and thus
can be dropped.
