Subject[PATCH] i386 config
Date
Hi,

I noticed that it is impossible to select "Math emulation" in
test12-pre* basing on the default config in a single configuration process
using Menuconfig or xconfig. It is because of CONFIG_X86_FXSR being never
unset/set to "n". The following patch fixes this problem (the first chunk)
and it also contains some indentation fixes.

The second problem (the second patch) concerns CONFIG_JFFS_FS checking
in fs/config.in. Checking for != "n" there breaks xconfig, as it never
sets dep_* variables to "n". It is a well known xconfig bug, but not
easily fixable.

Regards
Andrzej
