sparc64: Kill CONFIG_SPARC32_COMPAT
Browse files Browse the repository at this point in the history
It's completely superfluous, CONFIG_COMPAT is sufficient.

What this used to be is an umbrella for enabling code shared
by all 32-bit compat binary support types.  But with the
removal of SunOS and Solaris support, the only one left is
Linux 32-bit ELF.

Update defconfig.

This allows you to run 32-bit binaries on your 64-bit SPARC system.
Everybody wants this; say Y.
