more than that, 3 commits just after that commit should be reverted at
the same time.
they all depend on that commit.

and first checking of that commit, it would have problem with system
more than 512g ...

static int insert_identity_mapping(resource_size_t paddr, unsigned long vaddr,
unsigned long size)
pgd_t *vpgd, *ppgd;
ppgd = __va(real_mode_header->trampoline_pgd) + pgd_index(paddr);

it missed one . we should use

ppgd = (pgd_t *)__va(real_mode_header->trampoline_pgd) + pgd_index(paddr);
