Jann Horn a0341fc198 ibmasm: don't write out of bounds in read handler 
This read handler had a lot of custom logic and wrote outside the bounds of
the provided buffer. This could lead to kernel and userspace memory
corruption. Just use simple_read_from_buffer() with a stack buffer.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
