We found the following warning when build kernel with W=1:
fs/fs_parser.c:192:5: warning: no previous prototype for ‘fs_param_bad_value’

Similar to what we need to do for VMX, the MSR permission bitmap
should not be accessed until the first KVM_RUN. This is important
because the memory map might not be up-to-date at the time of
KVM_SET_NESTED_STATE.
Paolo Bonzini (2):
KVM: x86: rename KVM_REQ_GET_VMCS12_PAGES
KVM: nSVM: delay
Allow userspace to set up the memory map after KVM_SET_NESTED_STATE;
to do so, move the call to nested_svm_vmrun_msrpm inside the
KVM_REQ_GET_NESTED_STATE_PAGES handler (which is currently
not used by nSVM). This is similar to what VMX does already.

We are going to use it for SVM too, so use a more generic name.

Hi all,
Changes since 20200925:
The vfs tree lost its build failure, but gained another for which I
applied a fix patch.
The net-next tree gained a conflict against the net tree.
The drm tree gained a build failure due to a semantic conflict with the
dma-mapping tree for which I have disabled a

When call function devm_platform_ioremap_resource(), we should use
IS_ERR() to check the return value and return PTR_ERR() if failed,
and it can print an error message itself if failed. So remove the
redundant dev_err() in this place.

KVM special-cases writes to MSR_IA32_TSC so that all CPUs have
the same base for the TSC. This logic is complicated, and we
do not want it to have any effect once the VM is started.
In particular, if any guest started to synchronize its TSCs
with writes to MSR_IA32_TSC rather than MSR_IA32_TSC_AD

While not destroying mutexes doesn't lead to memory leaks, it's still
the correct thing to do for mutex debugging accounting.
