linux /vmlinuz "foo bar"

In GRUB "foo bar" will be quoted and passed as single parameter to
"linux" command, then GRUB will add quotes again before building kernel
command line so kernel will see "foo bar" (with double quotes). What
happens later depends on kernel and/or programs that parse /proc/cmdline.

In general it is better to avoid spaces, it is always asking for
problems sooner or later.
