Subject: [merged] efi-provide-empty-efi_enter_virtual_mode-implementation.patch removed from -mm tree
Date: Sun, 09 Aug 2020 19:39:29 -0700	[thread overview]
Message-ID: <20200810023929.xyUCDlLLz%akpm@linux-foundation.org> (raw)


The patch titled
     Subject: efi: provide empty efi_enter_virtual_mode implementation
has been removed from the -mm tree.  Its filename was
     efi-provide-empty-efi_enter_virtual_mode-implementation.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Andrey Konovalov <andreyknvl@google.com>
Subject: efi: provide empty efi_enter_virtual_mode implementation

When CONFIG_EFI is not enabled, we might get an undefined reference to
efi_enter_virtual_mode() error, if this efi_enabled() call isn't inlined
into start_kernel().  This happens in particular, if start_kernel() is
annodated with __no_sanitize_address.
