1) Can somebody throw some light on what exactly is the difference
between m8xx_cpm_hostalloc() and kmalloc().

1) Cache coherency, and 2) need to allocate memory to CPM before the
kernel memory allocator has been initialized.

2) Why is the difference important in ppc linux ?

It's unique to the 8xx/82xx/85xx CPM peripherals that are used early
in the kernel start up process, not to the PowerPC Linux in general.
