[PATCH] x86, efi: free memory with the correct call

From: Maarten Lankhorst
Date: Mon Jun 06 2011 - 11:57:51 EST


Commit 916f676f8dc introduced a call to free_bootmem_late while it
reserves memory with memblock_x64_reserve_range
Fix this call to silence the swapper BUGs:

BUG: Bad page state in process swapper pfn:00000
