Memory for passing additional parameters to fadump capture kernel
is allocated during subsys_initcall level, using memblock. But
as slab is already available by this time, allocation happens via
the buddy allocator. This may work for radix MMU but is likely to
fail in most cases for hash MMU as hash MMU needs this memory in
the first memory block for it to be accessible in real mode in the
capture kernel (second boot). So, allocate memory for additional
parameters area as soon as MMU mode is obvious.

Version v2 of this series was applied.
If needed, can you rebase this patch ?
Sorry, I didn't get that. Rebase on top of which tree/branch?
I meant on top of any tree including the applied version.
FYI, there was no functional change from v2 to v3. Only a
"Reviewed-by" tag was added.
Then I guess there is nothing to do.
Christophe
