Subject: [PATCH 3/3] KVM: PPC: Fix mmio length message
Date: Thu, 23 Dec 2021 18:15:28 -0300 [thread overview]
Message-ID: <20211223211528.3560711-4-farosas@linux.ibm.com> (raw)
In-Reply-To: <20211223211528.3560711-1-farosas@linux.ibm.com>
We check against 'bytes' but print 'run->mmio.len' which at that point
has an old value.
e.g. 16-byte load:
before:
__kvmppc_handle_load: bad MMIO length: 8
now:
__kvmppc_handle_load: bad MMIO length: 16
