[PATCH] Docs/mm: fix documentation warning for GFP parameter in kmalloc_obj, kmalloc_objs and kmalloc_flex

[Jakov Novak]

Compiling the documentation currently gives the errors:

WARNING: ./include/linux/slab.h:1100 Excess function parameter 'GFP' description in 'kmalloc_obj'
WARNING: ./include/linux/slab.h:1112 Excess function parameter 'GFP' description in 'kmalloc_objs'
WARNING: ./include/linux/slab.h:1127 Excess function parameter 'GFP' description in 'kmalloc_flex'
WARNING: ./include/linux/slab.h:1100 Excess function parameter 'GFP' description in 'kmalloc_obj'
WARNING: ./include/linux/slab.h:1112 Excess function parameter 'GFP' description in 'kmalloc_objs'
WARNING: ./include/linux/slab.h:1127 Excess function parameter 'GFP' description in 'kmalloc_flex'

This effectively omits the GFP parameter from the current kernel
documentation. This patch marks the "..." parameter with the previous
description of the GFP parameter along with an "optional" tag in
parantheses.
