1d45edeb90 selinux: don't require auditing 
Audit is bad. It affects performance under all circumstances. It's also
dirty.

From LWN: "Andy submitted a patch to fix this particular problem, but he
didn't stop there. He has come to the conclusion that the audit
subsystem is beyond repair, so his patch marks the whole thing as being
broken, making it generally inaccessible. He cited a number of problems
beyond this security issue: it hurts performance even when it is not
being used, it is not (in his mind) reliable, it has problems with
various architectures, and "its approach to freeing memory is
terrifying." All told, Andy said, we're better off without it"

c403bdb631 KVM: VMX: Do not allow reexecute_instruction() when skipping MMIO instr 
[ Upstream commit c4409905cd6eb42cfd06126e9226b0150e05a715 ]

Re-execution after an emulation decode failure is only intended to
handle a case where two or vCPUs race to write a shadowed page, i.e.
we should never re-execute an instruction as part of MMIO emulation.
As handle_ept_misconfig() is only used for MMIO emulation, it should
pass EMULTYPE_NO_REEXECUTE when using the emulator to skip an instr
in the fast-MMIO case where VM_EXIT_INSTRUCTION_LEN is invalid.

And because the cr2 value passed to x86_emulate_instruction() is only
destined for use when retrying or reexecuting, we can simply call
emulate_instruction().

Fixes: d391f1207067 ("x86/kvm/vmx: do not use vm-exit instruction length
                      for fast MMIO when running nested")

f5c517bbcb arm64: smp: fix smp_send_stop() behaviour 
commit d0bab0c39e32d39a8c5cddca72e5b4a3059fe050 upstream.

On a system with only one CPU online, when another one CPU panics while
starting-up, smp_send_stop() will fail to send any STOP message to the
other already online core, resulting in a system still responsive and
alive at the end of the panic procedure.

Make smp_send_stop() account also for the online status of the calling CPU
while evaluating how many CPUs are effectively online: this way, the right
number of STOPs is sent, so enforcing a proper freeze of the system at the
end of panic even under the above conditions.
