[Qemu-ppc] [PATCH] PowerPC: Add TM bits into msr_mask


From: wei . guo . simon
Subject: [Qemu-ppc] [PATCH] PowerPC: Add TM bits into msr_mask
Date: Wed, 28 Feb 2018 09:51:37 +0800

From: Simon Guo <address@hidden>

During migration, cpu_post_load() will use msr_mask to determine which
PPC MSR bits will be sync to the target side. Hardware Transaction
Memory(HTM) has been supported since Power8. This patch adds TM/TS bits
into msr_mask for Power8, so that transactional application can be
migrated across qemu.
