commit 0ef3439cd80ba7770723edb0470d15815914bb62 upstream.
Fix a regression caused by making the 486SX separately selectable in
Kconfig, for which the HIGHMEM64G setting has not been updated and
therefore has become exposed as a user-selectable option for the M486SX
configuration setting unlike with original M486 and all the other
settings that choose non-PAE-enabled processors:
High Memory Support
> 1. off (NOHIGHMEM)
2. 4GB (HIGHMEM4G)
3. 64GB (HIGHMEM64G)
choice[1-3?]:
With the fix in place the setting is now correctly removed:
High Memory Support
> 1. off (NOHIGHMEM)
2. 4GB (HIGHMEM4G)
choice[1-2?]:
