Subject: [PATCH] ARM: KVM: fix KVM_CAP_ARM_SET_DEVICE_ADDR reporting
Date: Wed, 3 Apr 2013 10:43:13 +0100 [thread overview]
Message-ID: <1364982193-21867-1-git-send-email-marc.zyngier@arm.com> (raw)
Commit 3401d54696f9 (KVM: ARM: Introduce KVM_ARM_SET_DEVICE_ADDR
ioctl) added support for the KVM_CAP_ARM_SET_DEVICE_ADDR capability,
but failed to add a break in the relevant case statement, returning
the number of CPUs instead.
Luckilly enough, the CONFIG_NR_CPUS=0 patch hasn't been merged yet
(https://lkml.org/lkml/diff/2012/3/31/131/1), so the bug wasn't
noticed.
Just give it a break!
