Ahh. I can re-create that now.
Yes, doing
make ARCH=i386 allnoconfig
followed by
make oldconfig
is broken. And doing a trivial "git bisect run" to pinpoint where
CONFIG_64BIT goes away gives us
f467c5640c29ad258c3cd8186a776c82fc3b8057 is the first bad commit
which does that
"kconfig: only write '# CONFIG_FOO is not set' for visible symbols"
and it turns out that CONFIG_64BIT is not a visible symbol on x86-32,
because that question is disabled when ARCH != "x86".
bool "64-bit kernel" if ARCH = "x86"
And the problem with that, is that *next* time around this config file
is used, because we don't have that
# CONFIG_64BIT is not set
line, we don't turn it into
CONFIG_64BIT=n
and then the "depends on" in X86_64
config X86_64
def_bool y
depends on 64BIT
no longer hides it.
Hmm. Ulf, Masahiro, comments?
Should we just revert that commit?
Thomas, can you verify that a
git revert f467c5640c29ad258c3cd8186a776c82fc3b8057
fixes the problem for you?
