Subject: alpha: remove __init annotation from exported page_is_ram()
From: Masahiro Yamada <masahiroy@xxxxxxxxxx>
commit 6ccbd7fd474674654019a20177c943359469103a upstream.
EXPORT_SYMBOL and __init is a bad combination because the .init.text
section is freed up after the initialization.
Commit c5a130325f13 ("ACPI/APEI: Add parameter check before error
injection") exported page_is_ram(), hence the __init annotation should
be removed.
This fixes the modpost warning in ARCH=alpha builds:
WARNING: modpost: vmlinux: page_is_ram: EXPORT_SYMBOL used for init symbol. Remove __init or EXPORT_SYMBOL.
Fixes: c5a130325f13 ("ACPI/APEI: Add parameter check before error injection")
