Hi,
I was playing around with kvm's nested virtualization feature on Intel
VT-x. When trying to access the GUEST_SMBASE (offset 0x4828)field of the
VMCS I got a "VMREAD/VMWRITE from/to unsupported VMCS component" error.
According to the Intel manual this field is not optional. The error

The fact that both spin_needbreak() and spin_is_contended() can be
used outside of sched is a bit confusing.
For example, in mm/com

There are two functions in this asm-generic file. Looking at
other arch which do not use the generic version, these two fcns
are within an #ifdef __KERNEL__ block, so make the generic one
consistent with those.
