linux/arch/mips
Linus Torvalds 0c02183427 ARM:
* Clean up vCPU targets, always returning generic v8 as the preferred target
 
 * Trap forwarding infrastructure for nested virtualization (used for traps
   that are taken from an L2 guest and are needed by the L1 hypervisor)
 
 * FEAT_TLBIRANGE support to only invalidate specific ranges of addresses
   when collapsing a table PTE to a block PTE.  This avoids that the guest
   refills the TLBs again for addresses that aren't covered by the table PTE.
 
 * Fix vPMU issues related to handling of PMUver.
 
 * Don't unnecessary align non-stack allocations in the EL2 VA space
 
 * Drop HCR_VIRT_EXCP_MASK, which was never used...
 
 * Don't use smp_processor_id() in kvm_arch_vcpu_load(),
   but the cpu parameter instead
 
 * Drop redundant call to kvm_set_pfn_accessed() in user_mem_abort()
 
 * Remove prototypes without implementations
 
 RISC-V:
 
 * Zba, Zbs, Zicntr, Zicsr, Zifencei, and Zihpm support for guest
 
 * Added ONE_REG interface for SATP mode
 
 * Added ONE_REG interface to enable/disable multiple ISA extensions
 
 * Improved error codes returned by ONE_REG interfaces
 
 * Added KVM_GET_REG_LIST ioctl() implementation for KVM RISC-V
 
 * Added get-reg-list selftest for KVM RISC-V
 
 s390:
 
 * PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
   Allows a PV guest to use crypto cards. Card access is governed by
   the firmware and once a crypto queue is "bound" to a PV VM every
   other entity (PV or not) looses access until it is not bound
   anymore. Enablement is done via flags when creating the PV VM.
 
 * Guest debug fixes (Ilya)
 
 x86:
 
 * Clean up KVM's handling of Intel architectural events
 
 * Intel bugfixes
 
 * Add support for SEV-ES DebugSwap, allowing SEV-ES guests to use debug
   registers and generate/handle #DBs
 
 * Clean up LBR virtualization code
 
 * Fix a bug where KVM fails to set the target pCPU during an IRTE update
 
 * Fix fatal bugs in SEV-ES intrahost migration
 
 * Fix a bug where the recent (architecturally correct) change to reinject
   #BP and skip INT3 broke SEV guests (can't decode INT3 to skip it)
 
 * Retry APIC map recalculation if a vCPU is added/enabled
 
 * Overhaul emergency reboot code to bring SVM up to par with VMX, tie the
   "emergency disabling" behavior to KVM actually being loaded, and move all of
   the logic within KVM
 
 * Fix user triggerable WARNs in SVM where KVM incorrectly assumes the TSC
   ratio MSR cannot diverge from the default when TSC scaling is disabled
   up related code
 
 * Add a framework to allow "caching" feature flags so that KVM can check if
   the guest can use a feature without needing to search guest CPUID
 
 * Rip out the ancient MMU_DEBUG crud and replace the useful bits with
   CONFIG_KVM_PROVE_MMU
 
 * Fix KVM's handling of !visible guest roots to avoid premature triple fault
   injection
 
 * Overhaul KVM's page-track APIs, and KVMGT's usage, to reduce the API surface
   that is needed by external users (currently only KVMGT), and fix a variety
   of issues in the process
 
 This last item had a silly one-character bug in the topic branch that
 was sent to me.  Because it caused pretty bad selftest failures in
 some configurations, I decided to squash in the fix.  So, while the
 exact commit ids haven't been in linux-next, the code has (from the
 kvm-x86 tree).
 
 Generic:
 
 * Wrap kvm_{gfn,hva}_range.pte in a union to allow mmu_notifier events to pass
   action specific data without needing to constantly update the main handlers.
 
 * Drop unused function declarations
 
 Selftests:
 
 * Add testcases to x86's sync_regs_test for detecting KVM TOCTOU bugs
 
 * Add support for printf() in guest code and covert all guest asserts to use
   printf-based reporting
 
 * Clean up the PMU event filter test and add new testcases
 
 * Include x86 selftests in the KVM x86 MAINTAINERS entry
