99 # Don't discard allocated memory used to track "memory" and "reserved" memblocks
100 # after early boot, so it can still be used to test for validity of memory.
141 determines what happens to newly added memory regions. Policy setting
145 Say Y here if you want all hot-plugged memory blocks to appear in
147 Say N here if you want the default policy to keep all hot-plugged
167 # Default to 4 for wider testing, though 8 might be more appropriate.
169 # PA-RISC 7xxx's spinlock_t would enlarge struct page from 32 to 44 bytes.
171 # a per-page lock leads to problems when multiple tables need to be locked

| D | Kconfig.debug | 6 could be used for debugging features that need to insert extra
7 field for every page. This extension enables us to save memory
8 by not allocating this extra memory according to boottime
19 slowdown, but helps to find certain types of memory corruption.
33 pages are not saved to the suspend image.
