[PATCH] validate_mem without CONFIG_ISA - 2.4.x backport

[Pavel Roskin]

Hello!

My patch to fix a crash in validate_mem() without CONFIG_ISA defined
(http://lists.infradead.org/pipermail/linux-pcmcia/2003-April/000039.html)
needs to be applied to 2.4.x kernels as well.  The patch against
2.4.21-rc2-ac2 is attached.

Can anybody apply or forward the patch or I should send it in Marcelo
and/or Alan myself?
