o Commit 1833d6bc72
broke the build if
compiled with CONFIG_ES7000=y and CONFIG_X86_GENERICARCH=n

: undefined reference to `acpi_madt_oem_check'

: undefined reference to `mps_oem_check'

: undefined reference to `enable_apic_mode'
make: *** [.tmp_vmlinux1] Error 1
o Fix the build issue. Provided the definitions of missing functions.
o Don't have ES7000 machine. Only compile tested.
