Impact: fix es7000 compiling

make[1]: *** [arch/x86/kernel/es7000_32.o] Error 1

we applied one patch out of order...
| commit a73aaedd95703bd49f4c3f9df06fb7b7373ba905
| Author: Yinghai Lu <yhlu.kernel@gmail.com>
| Date: Sun Sep 14 02:33:14 2008 -0700
|
| x86: check dsdt before find oem table for es7000, v2
|
| v2: use __acpi_unmap_table()

that patch need
x86: use early_ioremap in __acpi_map_table
x86: always explicitly map acpi memory
acpi: remove final __acpi_map_table mapping before setting acpi_gbl_permanent_mmap
acpi/x86: introduce __apci_map_table, v4

workaround it here

after those patches applied, need to revert this one
