Subject: [GIT PULL] First batch of KVM changes for Linux 5.12
Linus,
I am sending an early pull request with the material that does not depend
on any bare metal changes, especially since ARM64 and PPC submaintainers
have already sent their stuff to me.
The following changes since commit 87aa9ec939ec7277b730786e19c161c9194cc8ca:
KVM: x86/mmu: Fix TDP MMU zap collapsible SPTEs (2021-02-04 04:38:53 -0500)
are available in the Git repository at:
https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus

Merge tag 'kvmarm-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2021-02-12 11:23:44 -0500)
----------------------------------------------------------------
x86:
- Support for userspace to emulate Xen hypercalls
- Raise the maximum number of user memslots
- Scalability improvements for the new MMU. Instead of the complex
"fast page fault" logic that is used in mmu.c, tdp_mmu.c uses an
rwlock so that page faults are concurrent, but the code that can run
against page faults is limited. Right now only page faults take the
lock for reading; in the future this will be extended to some
cases of page table destruction. I hope to switch the default MMU
around 5.12-rc3 (some testing was delayed due to Chinese New Year).
- Cleanups for MAXPHYADDR checks
- Use static calls for vendor-specific callbacks
- On AMD, use VMLOAD/VMSAVE to save and restore host state
- Stop using deprecated jump label APIs
- Workaround for AMD erratum that made nested virtualization unreliable
- Support for LBR emulation in the guest
- Support for communicating bus lock vmexits to userspace
- Add support for SEV attestation command
- Miscellaneous cleanups
PPC:
- Support for second data watchpoint on POWER10
- Remove some complex workarounds for buggy early versions of POWER9
- Guest entry/exit fixes
ARM64
- Make the nVHE EL2 object relocatable
- Cleanups for concurrent translation faults hitting the same page
- Support for the standard TRNG hypervisor call
- A bunch of small PMU/Debug fixes
- Simplification of the early init hypercall handling
Non-KVM changes (with acks):
- Detection of contended rwlocks (implemented only for qrwlocks,
because KVM only needs it for x86)
- Allow __DISABLE_EXPORTS from assembly code
- Provide a saner follow_pfn replacements for modules
----------------------------------------------------------------
Regarding conflicts, I would have expected git to figure it out,
but anyway the line in the pull request is the correct one:
<<<<<<< pull request (correct)
vcpu->arch.reserved_gpa_bits = kvm_vcpu_reserved_gpa_bits_raw(vcpu);
=======
vcpu->arch.cr3_lm_rsvd_bits = rsvd_bits(cpuid_maxphyaddr(vcpu), 63);
>>>>>>> 5.11

Paolo
