sparse_init() requires to temporary allocate two large buffers:

large that Linux is not bootable on small memory machines, such as a kdump

Changelog:
v1 - v2
- Addressed comments from Oscar Salvador
In sparse_init() we allocate two large buffers to temporary hold usemap and

Change sprase_init() to only find the pnum ranges that belong to a specific

Delete all the code that became obsolete with this change.
