caused by
4645b6af9427: x86: Use early pre-allocated page table buffer top-down

32 bit fixmap will use the pre-allocated range too. it needs range to
be continuous...

please drop
4645b6af9427: x86: Use early pre-allocated page table buffer top-down
3c417751e4f0: x86: Rename e820_table_* to pgt_buf_*

and will send out new version of

 x86: Rename e820_table_* to pgt_buf_*

Thanks
