hi
I'm looking for a way to make a ramdisk which is not erased on reboot
this is for use with ipaq/linux.
i tought of booting with mem=32m and map a block device to the rest of
the 32M ram i have.
the probelm is that giving mem=32m to the kernel will cause the kernel
to map only the first 32m of physical memory to virtual one, so using
__pa(ptr) on the top 32m causes a kernel oops.
any idea ?
regards
erez.
