x86: Ioremap: fix wrong physical address handling in PAT code
The following two commits fixed a problem that x86 ioremap() doesn't handle
physical address higher than 32-bit properly in X86_32 PAE mode.
ffa71f33a820d1ab3f2fc5723819ac60fb76080b (x86, ioremap: Fix incorrect
physical address handling in PAE mode)
35be1b716a475717611b2dc04185e9d80b9cb693 (x86, ioremap: Fix normal
ram range check)
But these fixes are not enough, since pat_pagerange_is_ram() in PAT code
also has a same problem. This patch fixes it.
