[Xen-devel] [PATCH v3 0/6] x86: Meltdown band-aid overhead reduction
1: NOP out most XPTI entry/exit code when it's not in use
2: disable XPTI when RDCL_NO
3: x86: log XPTI enabled status
4: use %r12 to write zero into xen_cr3
5: reduce .text.entry
6: avoid double CR3 reload when switching to guest user mode
