I am trying to port something that I had written for 2.0.22 to 2.1.32 and
I ran into major problems....
I had used some kernel functions that were there in 2.0.22 but now
they are missing in 2.1.32. they are
vremap (which used to be in mm/vmalloc.h)
proc_register_dynamic (used to be in fs/proc/root.c)
and memcpy_fromfs/tofs (used to be in asm/segment.h
(now only in asm-mips/segment.h))
Suprisingly i find that there are some kernel routines that use the above
functions (for example proc_register_dynamic is sunrpc/stats.c)
Now my question is why have these been removed?
Why do files that use these compile (or do they??)
and what can i use as a replacement for these functions...
Sorry if I am asking something that has already been discussed on this list..
Also I checked and saw a note in drivers/scsi/ncr53c8xx.c which said that
I should use ioremap instead of vremap....do they perform the same
function??? (what I want to do is allocate a space for my module
that is beyond the physical address space for the kernel but exists in
the main memory... ie. in my 32 MB box, I want to keep 8 MB for my stuff
that the rest of the kernel cannot use...so I used to pass a mem=24M to
the lilo command line and then map the remaining 8MB for my use...)
thanx in advance
