The patch titled
Subject: mm/sparse: use memblock apis for early memory allocations
has been removed from the -mm tree. Its filename was
mm-sparse-use-memblock-apis-for-early-memory-allocations.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Santosh Shilimkar <santosh.shilimkar@xxxxxx>
Subject: mm/sparse: use memblock apis for early memory allocations
Switch to memblock interfaces for early memory allocator instead of
bootmem allocator. No functional change in beahvior than what it is in
current code from bootmem users points of view.
Archs already converted to NO_BOOTMEM now directly use memblock interfaces
instead of bootmem wrappers build on top of memblock. And the archs which
still uses bootmem, these new apis just fallback to exiting bootmem APIs.
