Subject: [PATCH 03/12] efi/arm*: Stop printing addresses of virtual mappings
Date: Thu,  8 Mar 2018 08:00:11 +0000	[thread overview]
Message-ID: <20180308080020.22828-4-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20180308080020.22828-1-ard.biesheuvel@linaro.org>

With the recent %p -> %px changes, we now get something like this in
the kernel boot log on ARM/arm64 EFI systems:

     Remapping and enabling EFI services.
       EFI remap 0x00000087fb830000 =>         (ptrval)
       EFI remap 0x00000087fbdb0000 =>         (ptrval)
       EFI remap 0x00000087fffc0000 =>         (ptrval)

The physical addresses of the UEFI runtime regions will also be
printed when booting with the efi=debug command line option, and the
virtual addresses can be inspected via /sys/kernel/debug/efi_page_tables
(if enabled). So let's just remove the lines above.
