Subject: [PATCH 1/3] ACPI: scan: substitute empty_zero_page with helper ZERO_PAGE(0)
Date: Tue, 18 Oct 2022 23:57:53 +0200	[thread overview]
Message-ID: <20221018215755.33566-1-giulio.benetti@benettiengineering.com> (raw)

Not all zero page implementations use empty_zero_page global pointer so
let's substitute empty_zero_page occurence with helper ZERO_PAGE(0).
