Did you mean to include <asm/acpi.h>?
Why?
Because arch_apei_report_x86_error() used in the patch is defined
there. The indirect include works but pulls in additional definitions
not needed by the patch.

Do you prefer the more generic include?

Okay.

I agree, it's generally a good practice to avoid pulling up additional
definitions. I had this when I made the declaration in generic header
file and may be I did not consider it changing initially as my build
didn't break after moving the declaration from generic header to arch
specific header file.

I will take care henceforth and make the changes as required.

Thanks,
