On a few places, it sometimes need to indicate a negation of a
parameter, like:
!@fshared
This pattern happens, for example, at:
kernel/futex.c
and it is perfectly valid. However, kernel-doc currently
transforms it into:
!**fshared**
This won't do what it would be expected.
Fortunately, fixing the script is a simple matter of storing
the "!" before "@" and adding it after the bold markup, like:

The pattern @foo->bar() is valid, as it can be used by a
function pointer inside a struct passed as a parameter.
Right now, it causes a warning:
./drivers/firewire/core-transaction.c:606: WARNING: Inline strong start-string without end-string.
In this specific case, the kernel-doc markup is:
/**
* fw_core_remove_address_handler() - unregister an address handler
* @handler: callback
*
* To be called in process context.
*
* When fw_core_remove_address_handler() returns, @handler->callback() is

In the switchdev mode, when running "cat
/sys/class/net/NIC/statistics/tx_packets", the ppcnt register is
accessed to get the latest values. But currently this command can
not get the correct values from ppcnt.
From firmware manual, before getting the 802_3 counters, the 802_3
data layout should be set to the ppcnt register.
When the command "cat /sys/class/net/NIC/statistics/tx_packets" is
run, before updating 802_3 data layout with ppcnt register, the
monitor counters are tested. The test result will decide the
802_3 data layout is updated or not.
Actually the monitor counters do not support to monitor rx/tx
stats of 802_3 in switchdev mode. So the rx/tx counters change
will not trigger monitor counters. So the 802_3 data layout will
not be updated in ppcnt register. Finally this command can not get
the latest values from ppcnt register with 802_3 data layout.

MLX5_CORE uses the 'imply' keyword to depend on VXLAN, PTP_1588_CLOCK,
MLXFW and PCI_HYPERV_INTERFACE.
This was useful to force vxlan, ptp, etc.. to be reachable to mlx5
regardless of their config states.
Due to the changes in the cited commit below, the semantics of 'imply'
was changed to not force any restriction on the implied config.
As a result of this change, the compilation of MLX5_CORE=y and VXLAN=m
would result in undefined references, as VXLAN now would stay as 'm'.
To fix this we change MLX5_CORE to have a weak dependency on
these modules/configs and make sure they are reachable, by adding:
depend on symbol || !symbol.
For example: VXLAN=m MLX5_CORE=y, this will force MLX5_CORE to m

Add a dedicated hook to handle flushing TLB entries on behalf of the
guest, i.e. for a paravirtualized TLB flush, and use it directly instead
of bouncing through kvm_vcpu_flush_tlb().
For VMX, change the effective implementation implementation to never do
INVEPT and flush only the current context, i.e. to always flush via
INVVPID(SINGLE_CONTEXT). The INVEPT performed by __vmx_flush_tlb() when
@invalidate_gpa=false and enable_vpid=0 is unnecessary, as it will only
flush guest-physical mappings; linear and combined mappings are flushed
by VM-Enter when VPID is disabled, and changes in the guest pages tables
do not affect guest-physical mappings.
When EPT and VPID are enabled, doing INVVPID is not required (by Intel's
architecture) to invalidate guest-physical mappings, i.e. TLB entries
that cache guest-physical mappings can live across INVVPID as the
mappings are associated with an EPTP, not a VPID. The intent of
@invalidate_gpa is to inform vmx_flush_tlb() that it must "invalidate
gpa mappings", i.e. do INVEPT and not simply INVVPID. Other than nested
VPID handling, which now calls vpid_sync_context() directly, the only
scenario where KVM can safely do INVVPID instead of INVEPT (when EPT is
enabled) is if KVM is flushing TLB entries from the guest's perspective,
i.e. is only required to invalidate linear mappings.
For SVM, flushing TLB entries from the guest's perspective can be done
by flushing the current ASID, as changes to the guest's page tables are
associated only with the current ASID.
Adding a dedicated ->tlb_flush_guest() paves the way toward removing
@invalidate_gpa, which is a potentially dangerous control flag as its
meaning is not exactly crystal clear, even for those who are familiar
with the subtleties of what mappings Intel CPUs are/aren't allowed to
keep across various invalidation scenarios.

Note, the "vpid == 0" checks in the vpid_sync_*() helpers aren't

Use vpid_sync_context() directly for flows that run if and only if
enable_vpid=1, or more specifically, nested VMX flows that are gated by
vmx->nested.msrs.secondary_ctls_high.SECONDARY_EXEC_ENABLE_VPID being
set, which is allowed if and only if enable_vpid=1. Because these flows
call __vmx_flush_tlb() with @invalidate_gpa=false, the if-statement that
decides between INVEPT and INVVPID will always go down the INVVPID path,
i.e. call vpid_sync_context() because
"enable_ept && (invalidate_gpa || !enable_vpid)" always evaluates false.
This helps pave the way toward removing @invalidate_gpa and @vpid from
__vmx_flush_tlb() and its callers.
Opportunstically drop unnecessary brackets in handle_invvpid() around an

such feature.
While here, add more comments to it, as the script is
getting more complex. So, better to add more things, to avoid
accidentally breaking it while improving it.

It seems that Mageia and OpenMandriva will reunite on a single
distribution. In any case, both came from Mandriva. So, it is
close enough to use the same logic.
So, add support for it.
Tested with OpenMandriva 4.1 and with Mageia 7.1.

Currently, with openSUSE Tumbleweed 20200303, it keeps
recommending this forever:
sudo zypper install --no-recommends rsvg-view
This dependency will never be fulfilled there, as the package
now is named as on other distros: rsvg-convert.
So, improve the detection to avoid such issue.

The Arch-linux detection is hit by catting /etc/issue, whose
contents is (nowadays):
Arch Linux \r (\l)
It sounds a little ackward to print such string, so,
instead, let's use the /etc/os-release file, with exists
on lots of distributions and should provide a more reliable
result.
We'll keep the old tests before it, in order to avoid possible
regressions with the other distros, although the new way should
probably work on all the currently supported distributions.

Frame pointers are completely broken by vmenter.S because it clobbers
RBP:
arch/x86/kvm/svm/vmenter.o: warning: objtool: __svm_vcpu_run()+0xe4: BP used as a scratch register
That's unavoidable, so just skip checking that file when frame pointers
are configured in.
On the other hand, ORC can handle that code just fine, so leave objtool
enabled in the !FRAME_POINTER case.

Commit 7561252892 ("audit: always check the netlink payload length
in audit_receive_msg()") fixed a number of missing message length
checks, but forgot to check the length of userspace generated audit
records. The good news is that you need CAP_AUDIT_WRITE to submit
userspace audit records, which is generally only given to trusted
processes, so the impact should be limited.

Call disable_interrupts() if we have to revert to polling in order not to

For the algorithm that does not match the bank, a positive

tpm_ibmvtpm_send() can fail during PowerVM Live Partition Mobility resume
with an H_CLOSED return from ibmvtpm_send_crq(). The PAPR says, 'The
"partner partition suspended" transport event disables the associated CRQ
such that any H_SEND_CRQ hcall() to the associated CRQ returns H_Closed
until the CRQ has been explicitly enabled using the H_ENABLE_CRQ hcall.'
This patch adds a check in tpm_ibmvtpm_send() for an H_CLOSED return from
ibmvtpm_send_crq() and in that case calls tpm_ibmvtpm_resume() and
retries the ibmvtpm_send_crq() once.
