The building of drivers/acpi/acpica/utglobal.o is throwing
a number of sparse warnins about undeclared symbols. This is
due to defining DEFINE_ACPI_GLOBALS then making the macro
ACPI_INIT_GLOBAL() define it but never declaring the fact this
is an extern declared varible.

This is some of the sparse warnings that are being fixed here:

drivers/acpi/acpica/utglobal.c: note: in included file (through include/acpi/acpi.h):
./include/acpi/acpixf.h:104:1: warning: symbol 'acpi_gbl_enable_interpreter_slack' was not declared. Should it be static?
./include/acpi/acpixf.h:113:1: warning: symbol 'acpi_gbl_auto_serialize_methods' was not declared. Should it be static?
./include/acpi/acpixf.h:120:1: warning: symbol 'acpi_gbl_create_osi_method' was not declared. Should it be static?
./include/acpi/acpixf.h:126:1: warning: symbol 'acpi_gbl_use_default_register_widths' was not declared. Should it be static?
./include/acpi/acpixf.h:136:1: warning: symbol 'acpi_gbl_enable_table_validation' was not declared. Should it be static?
./include/acpi/acpixf.h:141:1: warning: symbol 'acpi_gbl_enable_aml_debug_object' was not declared. Should it be static?
./include/acpi/acpixf.h:149:1: warning: symbol 'acpi_gbl_copy_dsdt_locally' was not declared. Should it be static?
./include/acpi/acpixf.h:157:1: warning: symbol 'acpi_gbl_do_not_use_xsdt' was not declared. Should it be static?

Note, if this isn't the correct place to fix, where should this be
going?

This file belongs to ACPICA.  As a general rule, ACPICA changes should
be submitted as pull requests to the upstream ACPICA project on
GitHub, from where they are backported (semi-automatically) to Linux.

However, if an upstream ACPICA pull request has been submitted, a
corresponding Linux patch can be posted with a Link: tag pointing to
that pull request.

Thanks!
