commit
063b8a4cee8088224bcdb79bcd08db98df16178e upstream.
The input parameter 'phys_index' of memory_block_action() is actually the
section number, but not the phys_index of memory_block. This is a relic
from the past when one memory block could only contain one section.
Rename it to start_section_nr.
And also in remove_memory_section(), the 'node_id' and 'phys_device'
arguments are not used by anyone. Remove them.
