4.12-stable review patch. If anyone has any objections, please let me know.
From: Gregory CLEMENT <gregory.clem...@free-electrons.com>
commit 76127d6fe00062bddb25515d8a4f44633c41fe14 upstream.
As we already did for Armada XP switch from virt_to_phys() to
The reason for it was well explained by Mark Rutland so let's quote him:
"virt_to_phys() is intended to operate on the linear/direct mapping of
__pa_symbol() is intended to operate on the kernel mapping, which may
not be in the linear/direct mapping on all architectures. e.g. arm64 and
x86_64 map the kernel image and RAM separately.
On 32-bit ARM the kernel image mapping is tied to the linear/direct
mapping, so that works, but as it's semantically wrong (and broken for
generic code), the DEBUG_VIRTUAL checks complain."
