KVM: x86/mmu: Don't save mmu_invalidate_seq after checking private attr (2024-06-05 06:45:06 -0400)
The pull request is dominated by a couple large series for ARM
and x86 respectively, but apart from that things are calm.
----------------------------------------------------------------
ARM:
* Large set of FP/SVE fixes for pKVM, addressing the fallout
from the per-CPU data rework and making sure that the host
is not involved in the FP/SVE switching any more
* Allow FEAT_BTI to be enabled with NV now that FEAT_PAUTH
is completely supported
* Fix for the respective priorities of Failed PAC, Illegal
Execution state and Instruction Abort exceptions
* Fix the handling of AArch32 instruction traps failing their
condition code, which was broken by the introduction of
ESR_EL2.ISS2
* Allow vcpus running in AArch32 state to be restored in
System mode
* Fix AArch32 GPR restore that would lose the 64 bit state
under some conditions
RISC-V:
* No need to use mask when hart-index-bits is 0
* Fix incorrect reg_subtype labels in kvm_riscv_vcpu_set_reg_isa_ext()
x86:
* Fixes and debugging help for the #VE sanity check. Also disable
it by default, even for CONFIG_DEBUG_KERNEL, because it was found
to trigger spuriously (most likely a processor erratum as the
exact symptoms vary by generation).
* Avoid WARN() when two NMIs arrive simultaneously during an NMI-disabled
situation (GIF=0 or interrupt shadow) when the processor supports
virtual NMI. While generally KVM will not request an NMI window
when virtual NMIs are supported, in this case it *does* have to
single-step over the interrupt shadow or enable the STGI intercept,
in order to deliver the latched second NMI.
* Drop support for hand tuning APIC timer advancement from userspace.
Since we have adaptive tuning, and it has proved to work well,
drop the module parameter for manual configuration and with it a
few stupid bugs that it had.
