[PATCH v8 6/9] vmcore: allocate ELF note segment in the 2nd kernel vmalloc memory

2013-05-22 Thread HATAYAMA Daisuke
The reasons why we don't allocate ELF note segment in the 1st kernel (old memory) on page boundary is to keep backward compatibility for old kernels, and that if doing so, we waste not a little memory due to round-up operation to fit the memory to page boundary since most of the buffers are in per-
