Hi,
I have noticed that virtio-rng only returns zero for kernels = 2.6.33

Wow.
Note: this is based on the latest master branch.
I'm sending this before 3.9-rc1 is released since this can cause extra
conflicts unless we make this available to all arch before we start
adding new stuff.
Please review: every change is trivial and should not change anything.

X86 does not use this any more. The remaining user, s390's !user_alloc
check, can be simply removed since KVM_SET_MEMORY_REGION ioctl is no
longer supported.
Note: fixed powerpc's indentations with spaces to suppress checkpatch
errors.
Signed-off-by: Takuya Yoshikawa
Except ia64's stale code, KVM_SET_MEMORY_REGION support, this is only
used for sanity checks in __kvm_set_memory_region() which can easily
be changed to use slot id instead.

This patch drops the parameter old, a copy of the old memory slot, and
adds a new parameter named change to know the change being requested.
This not only cleans up the code but also removes extra copying of the
memory slot structure.

This patch makes the parameter old a const pointer to the old memory
slot and adds a new parameter named change to know the change being
requested: the former is for removing extra copying and the latter is

the kvmclock initialization failed for whatever reason.

The physical memory fixmapped for the pvclock clock_gettime vsyscall
was allocated, and thus is not a kernel symbol. __pa() is the proper
method to use in this case.
