4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael S. Tsirkin <m...@redhat.com>
commit 766d3571d8e50d3a73b77043dc632226f9e6b389 upstream.
KVM_X86_DISABLE_EXITS_HTL really refers to exit on halt.
Obviously a typo: should be named KVM_X86_DISABLE_EXITS_HLT.
Fixes: caa057a2cad ("KVM: X86: Provide a capability to disable HLT intercepts")
