Subject: [PATCH] x86: fix es7000 compiling

es7000 is broken...

we applied one patch out of order...
| commit a73aaedd95703bd49f4c3f9df06fb7b7373ba905
| Author: Yinghai Lu <yhlu.kernel@...il.com>

|
|    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
