On failure to allocate from grub_relocator_firmware_alloc_region() in malloc_in_range() the function would stop enforcing the alignment, and the following was returned: lib/relocator.c:431: trying to allocate in 0x200000-0xffbf9fff aligned 0x200000 size 0x406000 lib/relocator.c:1197: allocated: 0x74de2000+0x406000 lib/relocator.c:1407: allocated 0x74de2000/0x74de2000 Fix this by making sure that target always contains a suitably aligned address. After the change the return from the function is: lib/relocator.c:431: trying to allocate in 0x200000-0xffb87fff aligned 0x200000 size 0x478000 lib/relocator.c:1204: allocated: 0x74c00000+0x478000 lib/relocator.c:1414: allocated 0x74c00000/0x74c00000 Fixes: 3a5768645c05 (First version of allocation from firmware) Signed-off-by: Roger Pau Monné <roger.pau@citrix.com> Reviewed-by: Daniel Kiper <daniel.kiper@oracle.com>
