follow the same structure.
Also remove board declarations tabs and double whitespace in the header.

Hi Oleksij,
We have tested this j1939 stack according to SAE J1939-21. It works fine for
most cases, but when we test multipacket broadcast message function we found
the receiver can't receive those packets.

Advertise pkr_mask to cache the conditions where pretection key checks
for supervisor pages are needed. When the accessed pages are those with
a translation for which the U/S flag is 0 in at least one
paging-structure entry controlling the translation, they are the
supervisor pages and PKRS
PKRU represents the PKU register utilized in the protection key rights
check for user pages. Protection Keys for Superviosr Pages (PKS) extends
the protection key architecture to cover supervisor pages.
Rename the *pkru* related variables and functions to *pkr* which stands
for both of the PKRU
PKS MSR passes through guest directly. Configure the MSR to match the
L0/L1 settings so that nested VM runs PKS properly.

PKS(Protection Keys for Supervisor Pages) is a feature that extends the
Protection Key architecture to support thread-specific permission
restrictions on supervisor pages.
A new PKS MSR(PKRS) is defined in kernel to support PKS, which holds a
set of permissions associated with each protection
Protection Keys for Supervisor Pages (PKS) uses IA32_PKRS MSR (PKRS) at
index 0x6E1 to allow software to manage supervisor protection key
rights. For performance consideration, PKRS intercept will be disabled
so that the guest can access the PKRS without VM exits.
PKS introduces dedicated control
This RFC series introduce the KVM support for PKS which have dependency
on PKS kernel patches for some definitions. The latest kernel patch set
can be found at

Protection Keys for Supervisor Pages(PKS) is a feature that
Existence of PKS is enumerated via CPUID.(EAX=7H,ECX=0):ECX[31]. It is
enabled by setting CR4.PKS when long mode is active. PKS is only
implemented when EPT is enabled and requires the support of VM_{ENTRY,
EXIT}_LOAD_IA32_PKRS currently.

pkr_mask bitmap indicates if protection key checks are needed for user
pages currently. It is indexed by page fault error code bits [4:1] with
PFEC.RSVD replaced by the ACC_USER_MASK from the page tables. Refactor
it by reverting to the use of PFEC.RSVD. After that, PKS and PKU can

The code for preallocate_vmalloc_pages() was written under the
assumption that the p4d_offset() and pud_offset() functions will perform
present checks before dereferencing the parent entries.
This assumption is wrong an leads to a bug in the code which causes the

KVM_GET_SUPPORTED_HV_CPUID is a vCPU ioctl but its output is now
independent from vCPU and in some cases VMMs may want to use it as a system
ioctl instead. In particular, QEMU doesn CPU feature expansion before any
vCPU gets created so KVM_GET_SUPPORTED_HV_CPUID can't be used.

Hyper-V Synthetic timers require SynIC but we don't seem to check that

kvm_vcpu_ioctl_get_hv_cpuid() doesn't use its vcpu parameter anymore,
drop it. Also, the function is now untied from vcpu, rename it accordingly.
No functional change intended.

KVM_GET_SUPPORTED_HV_CPUID was initially implemented as a vCPU ioctl but
this is not very useful when VMM is just trying to query which Hyper-V
features are supported by the host prior to creating VM/vCPUs. The data
in KVM_GET_SUPPORTED_HV_CPUID is mostly static with a few exceptions but

It is really inconvenient when KVM_GET_SUPPORTED_HV_CPUID output depends on
whether some other capabilities are enabled as VMM needs to be aware of the
correct sequence (which becomes an API).
Enlightened VMCS is not the only feature which requires explicit enablement.
In particular, SynIC has to
