Subject: [PATCH] Documentation: arm: Replace use of virt_to_phys with __pa_symbol
Date: Fri,  3 Mar 2017 12:42:01 +0100	[thread overview]
Message-ID: <1488541321-17225-1-git-send-email-geert+renesas@glider.be> (raw)

All low-level PM/SMP code using virt_to_phys() should actually use
__pa_symbol() against kernel symbols.  Update the documentation to move
away from virt_to_phys().

Cfr. commit 6996cbb2372189f7 ("ARM: 8641/1: treewide: Replace uses of
virt_to_phys with __pa_symbol")
