* grub-core/kern/mm.c (grub_real_malloc): Decrease cut-off of moving the
...
pointer to 32K. This is the size of cache element which is the most
common allocation >1K. This way the pointer is always around blocks
of 32K and so we keep performance while decreasing fragmentation.

* grub-core/kern/mm.c (grub_real_malloc): Don't update the pointer to
...
current memory when allocating large chunks. This significantly
decreases memory fragmentation.
