      Merge branch 'for-upstream' of git://github.com/agraf/linux-2.6 into next · 25e531a9
      由 Avi Kivity 提交于 
      Alex says:

"Changes this time include:

  - Generalize KVM_GUEST support to overall ePAPR code
  - Fix reset for Book3S HV
  - Fix machine check deferral when CONFIG_KVM_GUEST=y
  - Add support for BookE register DECAR"

* 'for-upstream' of git://github.com/agraf/linux-2.6:
  KVM: PPC: Not optimizing MSR_CE and MSR_ME with paravirt.
  KVM: PPC: booke: Added DECAR support
  KVM: PPC: Book3S HV: Make the guest hash table size configurable
  KVM: PPC: Factor out guest epapr initialization

      KVM: disable uninitialized var warning · 79f702a6
      由 Michael S. Tsirkin 提交于 
      I see this in 3.5-rc1:

arch/x86/kvm/mmu.c: In function ‘kvm_test_age_rmapp’:
arch/x86/kvm/mmu.c:1271: warning: ‘iter.desc’ may be used uninitialized in this function

The line in question was introduced by commit
1e3f42f0

 static int kvm_test_age_rmapp(struct kvm *kvm, unsigned long *rmapp,
                              unsigned long data)
 {
-       u64 *spte;
+       u64 *sptep;
+       struct rmap_iterator iter;   <- line 1271
        int young = 0;

        /*

The reason I think is that the compiler assumes that
the rmap value could be 0, so

static u64 *rmap_get_first(unsigned long rmap, struct rmap_iterator
*iter)
{
        if (!rmap)
                return NULL;

        if (!(rmap & 1)) {
                iter->desc = NULL;
                return (u64 *)rmap;
        }

        iter->desc = (struct pte_list_desc *)(rmap & ~1ul);
        iter->pos = 0;
        return iter->desc->sptes[iter->pos];
}

will not initialize iter.desc, but the compiler isn't
smart enough to see that

        for (sptep = rmap_get_first(*rmapp, &iter); sptep;
             sptep = rmap_get_next(&iter)) {

will immediately exit in this case.
I checked by adding
        if (!*rmapp)
                goto out;
on top which is clearly equivalent but disables the warning.

This patch uses uninitialized_var to disable the warning without
increasing code size.

      KVM: Cleanup the kvm_print functions and introduce pr_XX wrappers · a737f256
      由 Christoffer Dall 提交于 
      Introduces a couple of print functions, which are essentially wrappers
around standard printk functions, with a KVM: prefix.

Functions introduced or modified are:
 - kvm_err(fmt, ...)
 - kvm_info(fmt, ...)
 - kvm_debug(fmt, ...)
 - kvm_pr_unimpl(fmt, ...)
 - pr_unimpl(vcpu, fmt, ...) -> vcpu_unimpl(vcpu, fmt, ...)
