I see that /New/pcmcia-cs.20-Mar-98.tar.gz is out but it still needs:
/pcmcia/include/linux/config.h
#define CONFIG_MAX_MEMSIZE 1024
This is for the latest 2.1.x. I don't know if this addition breaks the
compile for earlier kernels but is necessary for 2.1.90.
This is a configurable option; your workaround works as long as the
kernel was configured with the default value for CONFIG_MAX_MEMSIZE.
Here's a patch to pcmcia's Configure script which *mostly* works. It
reads CONFIG_MAX_MEMSIZE either from a kernel source tree, or manually
from the keyboard. So as long as you pick one of those two options when
you run "make config" in the pcmcia directory, you'll be OK.
I haven't figured out a way to read CONFIG_MAX_MEMSIZE out of a running
kernel, though. I don't think it's currently possible; we'd probably
have to make a /proc interface to make this possible.
