From c2f69cdafebb3a46e43b5ac57ca12b539a2c790f Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Tue, 21 Jan 2014 15:50:27 -0800 Subject: kernel/power/snapshot.c: 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. Acked-by: "Rafael J.
