From: Dan Gopstein <dgopst...@nyu.edu>
Replace usages of the locally defined ABS() macro with calls to the
canonical abs() from kernel.h and remove the old definitions of ABS()
Signed-off-by: Dan Gopstein <dgopst...@nyu.edu>
---
v2->v3:
* replace local ABS() with kernel's abs()
v1->v2:
* unmangled the patch
* added example to commit text
