Subject: [RFC 26/37] KVM: s390: protvirt: Only sync fmt4 registers
Date: Thu, 24 Oct 2019 07:40:48 -0400	[thread overview]
Message-ID: <20191024114059.102802-27-frankja@linux.ibm.com> (raw)
In-Reply-To: <20191024114059.102802-1-frankja@linux.ibm.com>

A lot of the registers are controlled by the Ultravisor and never
visible to KVM. Also some registers are overlayed, like gbea is with
sidad, which might leak data to userspace.

Hence we sync a minimal set of registers for both SIE formats and then
check and sync format 2 registers if necessary.

Also we disable set/get one reg for the same reason. It's an old
interface anyway.
