Subject: [PATCH 12/13] KVM: arm: avoid binary number literals for gcc-4.2
Date: Fri, 16 Dec 2016 11:56:33 +0100 [thread overview]
Message-ID: <20161216105634.235457-13-arnd@arndb.de> (raw)
In-Reply-To: <20161216105634.235457-1-arnd@arndb.de>
Old gcc versions prior to 4.3 don't understand the 0b... syntax for
numbers, and this seems to be the only instance in the kernel, so better
use hexadecimal instead.
arch/arm/include/asm/kvm_mmu.h:127:38: error: invalid suffix "b101" on integer constant
Fixes: 159793001d7d ("ARM: KVM: force cache clean on page fault when caches are off")
