Indexed-count memory management allows addition and removal of contiguous
lmb blocks with a single command. When compared to the series of calls
previously required to manage contiguous blocks, indexed-count decreases
command frequency and reduces risk of buffer overflow.
Changes in v2:
--------------
-[PATCH 1/2]: -remove potential memory leak when parsing command
-use u32s drc_index and count instead of u32 ic[]
in dlpar_memory
-[PATCH 2/2]: -use u32s drc_index and count instead of u32 ic[]
in dlpar_memory
Changes in v3:
--------------
-[PATCH 1/2]: -add logic to handle invalid drc_index input
-update indexed-count trigger to follow naming convention
-update dlpar_memory to follow kernel if-else style
-[PATCH 2/2]: -add logic to handle invalid drc_index input
Changes in v4:
--------------
-[PATCH 1/2]: -add logic to handle kstrdup failure
-add logic to handle invalid command format
Changes in v5:
--------------
-[PATCH 2/2]: -update for() loop to use start_index
