Avi Kivity 58e690e6fd KVM: Fix bogus failure in kvm.ko module initialization
A bogus 'return r' can cause an otherwise successful module load to fail.
This both denies users the use of kvm, and it also denies them the use of
their machine, as it leaves a filesystem registered with its callbacks
pointing into now-freed module memory.

Fix by returning a zero like a good module.

Thanks to Richard Lucassen <mailinglists@lucassen.org> (?) for reporting
the problem and for providing access to a machine which exhibited it.

Avi Kivity bccf2150fe KVM: Per-vcpu inodes
Allocate a distinct inode for every vcpu in a VM.  This has the following
benefits:

 - the filp cachelines are no longer bounced when f_count is incremented on
   every ioctl()
 - the API and internal code are distinctly clearer; for example, on the
   KVM_GET_REGS ioctl, there is no need to copy the vcpu number from
   userspace and then copy the registers back; the vcpu identity is derived
   from the fd used to make the call

Right now the performance benefits are completely theoretical since (a) we
don't support more than one vcpu per VM and (b) virtualization hardware
inefficiencies completely everwhelm any cacheline bouncing effects.  But
both of these will change, and we need to prepare the API today.

Avi Kivity f17abe9a44 KVM: Create an inode per virtual machine
This avoids having filp->f_op and the corresponding inode->i_fop different,
which is a little unorthodox.

The ioctl list is split into two: global kvm ioctls and per-vm ioctls.  A new
ioctl, KVM_CREATE_VM, is used to create VMs and return the VM fd.

Bartlomiej Zolnierkiewicz 849138827c ide: make legacy IDE VLB modules check for the "probe" kernel params (v2)
Legacy IDE VLB host drivers didn't check for "probe" options when compiled
as modules, which was obviously wrong as we don't want module to poke at
random I/O ports by simply loading it.  Fix it by adding "probe" module param
to legacy IDE VLB host drivers.

v2:

Jan Beulich ed8ccee091 adjust legacy IDE resource setting (v2)
The change to force legacy mode IDE channels' resources to fixed non-zero
values confuses (at least some versions of) X, because the values reported
by the kernel and those readable from PCI config space aren't consistent
anymore.  Therefore, this patch arranges for the respective BARs to also
get updated if possible.
