[ Upstream commit 1aaa557b2db95c9506ed0981bc34505c32d6b62b ]
'make randconfig' can produce a .config file with
"CONFIG_MEMORY_RESERVE=" (no value) since it has no default.
When a subsequent 'make all' is done, kconfig restarts the config
and prompts for a value for MEMORY_RESERVE. This breaks
scripting/automation where there is no interactive user input.
Add a default value for MEMORY_RESERVE. (Any integer value will
work here for kconfig.)
Fixes a kconfig warning:
.config:214:warning: symbol value '' invalid for MEMORY_RESERVE
* Restart config...
Memory reservation (MiB) (MEMORY_RESERVE) [] (NEW)
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") # from beginning of git history
