Commit 2a2a64714d9c ("ACPI: Disable MWAIT via DMI on broken Compal board")
introduced a workaround for MWAIT for a specific x86 system.

Move the code outside of acpi_processor.c to acpi/x86/ directory for
consistency and rename the functions associated with it, so their names
start with "acpi_proc_quirk_" to make the goal obvious.

No intentional functional impact.


Except for:

ia64-linux-ld: drivers/acpi/acpi_processor.o: in function `acpi_early_processor_control_setup':
acpi_processor.c:(.init.text+0x712): undefined reference to `acpi_proc_quirk_mwait_check'
ia64-linux-ld: drivers/acpi/processor_pdc.o: in function `acpi_early_processor_set_pdc':
processor_pdc.c:(.init.text+0x72): undefined reference to `acpi_proc_quirk_mwait_check'

which breaks all ia64 builds.

Time to retire that architecture yet ? No one but me seems to even
build test it.

Including 0-day it seems. This had been in linux-next for several weeks.


Not sure if 0-day is running on linux-next nowadays. There are other
build failures in there which don't seem to be reported either.

Unfortunately, looking into build failures (and crashes) in linux-next
would be a full-time job. I see those failures, but I just don't have the
time to analyze and report them all.
