Subject[PATCH] fs/ext4/extents_status.c: fix 64-bit number truncation bug
'0x7FDEADBEEF' will be truncated to 32-bit number under unicore32. Need
append 'ULL' for it.

The related warning (with allmodconfig under unicore32):

CC [M] fs/ext4/extents_status.o
fs/ext4/extents_status.c: In function ‘__es_remove_extent’:
fs/ext4/extents_status.c:813: warning: integer constant is too large for ‘long’ type
