ACPI: Fix ARM32 platforms compile issue introduced by fw_table changes
Linus reported that:
After commit a103f46633fd the kernel stopped compiling for
several ARM32 platforms that I am building with a bare metal
compiler. Bare metal compilers (arm-none-eabi-) don't
define __linux__.
This is because the header <acpi/platform/acenv.h> is now
in the include path for <linux/irq.h>:
CC arch/arm/kernel/irq.o
CC kernel/sysctl.o
CC crypto/api.o
In file included from ../include/acpi/acpi.h:22,
from ../include/linux/fw_table.h:29,
from ../include/linux/acpi.h:18,
from ../include/linux/irqchip.h:14,
from ../arch/arm/kernel/irq.c:25:
../include/acpi/platform/acenv.h:218:2: error: #error Unknown target environment
218 | #error Unknown target environment
| ^~~~~
The issue is caused by the introducing of splitting out the ACPI code to
support the new generic fw_table code.
Rafael suggested [1] moving the fw_table.h include in linux/acpi.h to below
the linux/mutex.h. Remove the two includes in fw_table.h. Replace
linux/fw_table.h include in fw_table.c with linux/acpi.h.
