The patch titled
Subject: memblock: replace __alloc_bootmem with memblock_alloc_from
has been removed from the -mm tree. Its filename was
memblock-replace-__alloc_bootmem-with-memblock_alloc_from.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Mike Rapoport <rppt@linux.vnet.ibm.com>
Subject: memblock: replace __alloc_bootmem with memblock_alloc_from
The functions are equivalent, just the later does not require nobootmem
translation layer.
The conversion is done using the following semantic patch:
@@
expression size, align, goal;
@@
- __alloc_bootmem(size, align, goal)
+ memblock_alloc_from(size, align, goal)
