Subject: linux-next: manual merge of the kvm-ppc tree with the kvm tree
Hi Alexander,
Today's linux-next merge of the kvm-ppc tree got a conflict in
Documentation/virtual/kvm/api.txt between commit bf5590f37919 ("KVM:
Reformat KVM_SET_ONE_REG register documentation") from the kvm tree and
commit a0840240c0c6 ("KVM: PPC: Book3S: Fix LPCR one_reg interface")
from the kvm-ppc tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
Stephen Rothwell sfr@...b.auug.org.au

+ consists of those hcalls for which in-kernel handlers were implemented
+ before this capability was implemented. If disabled, the kernel will
+ not to attempt to handle the hcall, but will always exit to userspace
+ to handle it. Note that it may not make sense to enable some and
+ disable others of a group of related hcalls, but KVM does not prevent
+ userspace from doing that.
+
+ If the hcall number specified is not one that has an in-kernel
+ implementation, the KVM_ENABLE_CAP ioctl will fail with an EINVAL
+ error.
