Subject: [PATCH 0/6] KVM: towards maintainable kvm_make_all_cpus_request()
Date: Thu,  6 Apr 2017 22:20:50 +0200	[thread overview]
Message-ID: <20170406202056.18379-1-rkrcmar@redhat.com> (raw)

[1/6] makes a significant change for s390 and might be too dangerous
because of that.
I'm ok with returning 0 from s390's kvm_arch_vcpu_should_kick() until we
sort out architecture-specific kicks.

Adding kvm_vcpu_wake_up() in [6/6] is the reason why the other patches
were included.

Compile tested on s390, lightly tested and checked that kvm_*_request()
uses are being optimized on x86.


Radim Krčmář (6):
  KVM: fix guest_mode optimization in kvm_make_all_cpus_request()
  KVM: use kvm_{test,clear}_request instead of {test,clear}_bit
  KVM: x86: use kvm_make_request instead of set_bit
  KVM: remove #ifndef CONFIG_S390 around kvm_vcpu_wake_up
  KVM: mark requests that do not need a wakeup
  KVM: perform a wake_up in kvm_make_all_cpus_request
