Linus Torvalds 3e10585335 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
