From 8b89a1169437541a2a9b62c8f7b1a5c0ceb0fbde Mon Sep 17 00:00:00 2001 From: Grygorii Strashko Date: Tue, 21 Jan 2014 15:50:36 -0800 Subject: [PATCH] mm/hugetlb.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. Signed-off-by: Grygorii Strashko Signed-off-by: Santosh Shilimkar Cc: "Rafael J.
